Passive Systems

A thermosyphon system, which includes integrated collectors and what is known as a thermosyphon system, costs between $1,000 and $3,000 before the cost of labor.

Passive systems, which do not have a backup heater, rely on the heat from the sun and may involve complicated plumbing to separate the cold and hot water. Even while they are less expensive up front than the active choices, they are also more cumbersome and less trustworthy in colder climates.

Active Systems

Active systems are significantly more frequent in houses opting for a long-term, sustainable water heating technology, despite the fact that they have greater upfront expenditures. The two systems, which are referred to as direct and indirect, cost on average between $2,000 and $4,000 each. Direct systems are more effective in warm climates, but indirect systems, which incorporate the use of antifreeze and a heat exchanger, are most effective in cold climates. Additionally, these hookups are equipped with electric or gas backup generators, eliminating the risk of taking an ice-cold shower on a gloomy day.

What Factors Influence the Cost to Install a Solar Water Heater?

Professional water heater professionals will design each system to be specific to your home, including the amount of direct sunshine it receives and the amount of water you use on a daily basis. The following will be the expenses associated with this project:

As a matter of fact, expert installation is required in some areas.

Solar Water Heater Passive System Cost

With regard to solar energy, a passive or active version may be employed for an average cost of $1,000 to $3,000, depending on the model. Each one collects and stores water that has been heated by the sun for later use. Of the two methods, passive is the more affordable but also the less efficient and more restricting of the two. As a result, the active design will be advantageous to the majority of homeowners. This type is relatively simple to build and use, but it has a number of disadvantages as well.

This effectively means that a household will have to maintain their present water heater as a backup.

They can both be incredibly heavy, which will limit the areas where they can be properly put on a roof due to the weight of the equipment. Integral collector-storage and thermosyphon systems are the two types of passive solar heating systems.

  • Integral Collector-Storage (ICS): This type of collector is frequently less costly. A large number of homeowners have successfully constructed their own from the ground up. It prepares the water for the ordinary home tank by heating it. When hot water is required in the plumbing, the tank will draw from the “batch” that has been stored. ICS devices will not function in temperatures that fall below freezing or in conditions that are excessively heavy. Thermosyphon: This is a more costly option. The hot water rises to the top of the collector and is channeled into a storage tank below the collection. This tank’s level must be higher than the collector’s level in order to get anything. After that, it is transferred to a second tank within the house. The weight of these units is considerably greater than that of ICS units, and they may not be able to support the weight of some roofs. They also have a greater number of components.

Active Solar Heater Systems

Active solar water heaters are priced between $2,000 and $4,000. A solar collector as well as a heat storage facility are required. Due to the fact that the storage compartment can keep far more heat and is provided with an internal electric or gas backup, the chance of running out of hot water after several overcast days is almost eliminated. Although the technology is slightly more expensive to purchase and install, it removes the requirement for a typical backup unit. Due to the fact that it totally replaces the conventional system, only the expenses associated with an active system must be addressed.

  • Make use of gravity to transport water directly through the collector in order to heat it. A direct-acting kind works well in warm conditions
  • Indirect-acting types pump antifreeze via a collector, then return it to the tank, where it heats the water using a heat exchanger. Generally speaking, these sorts are more dependable in colder locations when temperatures fall below freezing.

“According to Jeff Botelho, a professional plumber and member of the Expert Board Review, indirect units require periodic maintenance to ensure that there are no cross connections between the antifreeze and the potable water system. “Because these units frequently require toxic antifreeze to function properly, indirect units require some periodic maintenance,” he says. “When selecting a solar water heater, keep in mind the expense of yearly or semiannual maintenance.”

Tank and Collector Sizes

The amount of equipment required will have a significant impact on the final cost. More utilization by households will necessitate increased storage capacity as well as an increase in energy consumption. The larger the collecting system, the greater the amount of energy required.

  • Calculating Collector Area- The rule of thumb is 40 square feet for a couple, and 8 to 14 square feet for each additional home consumer above and beyond that. This indicates that a minimum of 56 to 68 square feet must be set aside for roof installation for every four inhabitants. Calculating Tank Capacity- An 80-gallon system, which is considered typical, will provide the optimum performance for the average home. This is an excellent size for three to four people. A 50-gallon tank would be plenty for one to two people to live off of. In comparison, five or six persons use 120 gallons of water.

Solar Water Heater Installation Costs

The cost of solar water heater installation by a competent expert is around $70 per hour. The installation of these systems might be significantly more difficult than the installation of other types of water heaters. Installation of a traditional design will normally take no more than one day, whereas solar units may take many days to complete. As a result, labor expenses will account for a major portion of your total payment. Other elements that will influence your costs include whether the equipment will be used for a pool or spa, where it will be installed in and around the property, how much sun you can expect, and whether or not tax credits will be available for the equipment purchased.

Heating a Spa or Pool

Installing solar heaters for a pool or spa will cost between $3,000 and $4,000, depending on the size of the system. A solar collector, a filter, a flow control valve, and a pump are some of the components that will be used in the installation. The machine pushes water up from the pool or spa, past the filter, and into the collectors, where it is warmed by the collectors. The cost of installing other types of pool heating systems is not very different, but the solar version will have no ongoing operational expenses.

The major drawback is that a large number of collectors will be required, which would need a roof area that ranges from 50 percent to 100 percent of the pool’s surface area to accommodate them.

Location in the House

The complexity of installation and the number of hours required might vary significantly depending on where the collectors are being installed. Depending on the situation, they can be fastened to the roof, the wall, or the ground. Construction on the roof will be more perilous, and it will require more time and measures. Furthermore, the collectors’ closeness to their storage tank is critical. If they are located close enough to each other, less plumbing and labor will be required. Your contractor may select a location that is more remote simply because it will allow the collectors to be oriented for best solar exposure.

Sun Exposure

The complexity of installation as well as the number of hours required might vary substantially depending on where the collectors are being installed. Roofs, walls, and the ground can all be used as mounting points for these items. Roof work will be more perilous, and it will require more time and safety procedures as a consequence. Furthermore, the collectors’ closeness to their storage tank is critical. If they are located close enough to one another, less plumbing and labor will be required.

Tax Credits

The tax credit available for this equipment is 30%, which might have a significant influence on the ultimate cost of the equipment. The average $4,000 system would cost $2,800 if this amount were taken into consideration. On top of that, each state and each county has its own set of municipal incentives. There are state incentives that reward households with up to $6,000 in cash for the energy they save. Homeowners are more likely to receive rebates and incentives ranging from $1,000 to $3,000.

You may also inquire with your installing contractor or your utility provider for information on state and local rebates and incentives.

Advantages of Solar Water Heater/Geyser

There is a 30% tax credit available for this equipment, which might have a significant influence on the ultimate cost. The average $4,000 system would cost $2,800 if this amount were taken into account. State and municipal governments also provide their own incentives to encourage economic development. For energy savings, there are state incentives that may pay homes up to $6,000 in cash. Homes are more frequently eligible for rebates and incentives in the range of $1,000 to $3,000 per household.

You may also get information on state and municipal rebates from your installing contractor or your utility provider.

Disadvantages

Because everyone is virtually assured to receive significant savings month after month, one of the main drawbacks is the substantial initial investment required. The regular household will most likely struggle to come up with the necessary finances to have a professional installation performed. It may take months to save up for the expenditure, but in the long term, it may be well worth the effort to save up. It is expected that these systems would survive for decades, and their payback period is generally about three to six years.

There are a number of disadvantages to solar-powered systems that should be considered.

They will be able to run many appliances at the same time while heating water in this manner.

The solar collectors for a heater will only function in the direction of the water heater and will not supply the amount of power that a PV system can. PV systems are more expensive to install, with an average cost of roughly $27,000 to do so.

DIY or Hire a Pro?

The large initial investment is one of the only drawbacks because everyone is virtually assured to realize significant monthly savings. It is possible that the ordinary household will struggle to come up with the necessary finances to have a professional installation performed. While saving for the expenditure may take months, it may be well worth the effort in the long term. These systems are expected to survive for decades, with a payback period ranging from 3 to 6 years in most instances. Following that, any money saved on energy costs is turned into a profit for the homeowner’s benefit.

Others would like to have a set of panels that can generate enough electricity to power the entire house.

The solar collectors for a heater will only function in the direction of the water heater and will not give the amount of power that a PV system can offer.

FAQs

The sun’s warmth and solar energy are used to heat water for the residence, which is what it is really all about! In order to warm up the water, either it is cycled through a collector or it is warmed by the addition of a non-freezing liquid that has been heated in the collectors. The water is then kept in a tank until it is needed by the house or business.

How long do solar hot water systems last?

They have a lifetime of around 20 years on average. They are intended to endure between 15 and 30 years.

How hot do solar hot water heaters get?

They live an average of 20 years in the wild. 15 to 30 years is the expected lifespan of the item.

Do solar water heaters work on cloudy days?

The ability of solar water heaters to operate on overcast days is dependent on the circumstances. After several gloomy days, passive units will be unable to provide hot water and will be forced to rely on a backup heater to keep the water hot. Because of their increased thermal capacity and the availability of electric or gas backups, active systems can function for significantly longer periods of time when the sun is not shining.

Do solar hot water heaters save money?

Weather conditions determine whether solar water heaters are functional on overcast days. If there have been multiple overcast days, passive units will be unable to deliver hot water and will be forced to use a backup heater. Because of their increased thermal capacity and the availability of electric or natural gas backups, active systems can function for significantly longer periods of time when the sun is not shining.

Immediately following the completion of your installation, your solar hot water system will begin to provide free warm water using the sun’s energy. As a consequence, you will see immediate benefits in the form of much decreased utility expenses. Over the course of its long useful life, your solar hot water system will finally pay for itself and then some more. Solar hot water systems have a median lifespan of roughly 20 years, with some systems lasting considerably longer periods of time.

In addition to the financial benefits, installing solar hot water decreases your reliance on fossil fuels, which minimizes your carbon footprint and makes it a smart decision for the environment.

Cost of solar hot water systems

What is the potential cost of a solar hot water installation up front? Before rebates and incentives, the typical cost of a complete system is roughly $9,500 dollars. The anticipated price of $6,300 is based on the savings from the 26 percent home investment tax credit (ITC). Most importantly, the cost of your system is determined by the quality and size of the system you select. Building a solar hot water system built to serve a big family house, for example, will be more expensive than installing a system designed to serve a single or two inhabitants.

Financial benefits of solar hot water

Investing in a solar hot water system for your house will lower your monthly energy costs, but the actual amount you save will depend on the quantity of hot water you use, your location’s weather and solar potential, as well as any applicable incentives or tax breaks. Installing solar hot water will almost always result in a significant reduction in your monthly water heating expenditures. This is because the vast majority of your hot water will now be generated by free solar energy rather than by fossil fuels such as electricity, natural gas, or oil, all of which cost money on a monthly basis.

For example, the payback time for a system that replaces natural gas will be longer than the payback period for a system that replaces electricity or gasoline since natural gas is a less expensive fuel than electricity or gasoline.

Estimating the Cost and Energy Efficiency of a Solar Water Heater

Estimate the annual running costs of a solar water heating system before making a purchase decision and compare multiple solutions. If you invest in a more energy-efficient system, which will almost certainly cost more to acquire, you may calculate the energy savings and payback period over a longer period of time. Before you can pick and compare the costs of various systems, you must first determine the size of the system that will be necessary for your residence. For a solar water heating system, you will need the following information to calculate the annual running costs:

  • The solar energy factor (SEF) of the system is calculated. The kind of auxiliary tank fuel (gas or electric) and its expenses (current rates may be obtained from your local utility)

Solar energy factor (SEF) of the system; The kind of auxiliary tank fuel (gas or electric) and its expenses (current rates may be obtained from your local utility); and

WITH A GAS AUXILIARY TANK SYSTEM:

Natural gas, for example, is sometimes sold in units known as “therms.” 100 000 British thermal units are included in one (1) therm (Btus). Examine your utility bills to see how much fuel you consume during the summer months, when gas is not utilized for space heating. For example, if you use gas for cooking and drying clothing, you would wish to deduct around 60% of your summer total energy use as the energy required to heat water. When it comes to traditional water heaters, the Uniform Energy Factor (UEF) measures their energy efficiency.

  1. The higher the value of the UEF, the more energy-efficient the water heating system.
  2. Household gas water heaters must have a UEF of at least 0.64 in order to be compliant.
  3. Daily water heating energy = (summer months fuel use)*EF*0.6/ (summer months fuel use)*EF*0.6/ (summer months fuel use)*EF*0.6/ (number of days in summer months) The quantity of fuel consumed is proportional to the amount of water consumed and the temperature.
  4. Heat energy for daily water heating = (gallons of hot water per day)*(8.35 pounds per gallon)*(1 btu/lbs per degree Fahrenheit)*(1 btu/lbs per degree Fahrenheit)* (Hot water temperature- Cold water temperature).
  5. It is assumed that the incoming water temperature is 58 degrees Fahrenheit and the hot water temperature is 135 degrees Fahrenheit.
  6. With natural gas, this results in a daily water heating energy consumption of 0.4105 therms/day, or 12.03 kWh per day with electricity.

It is often preferable to size a solar system based on benchmark loads or the number of bedrooms in a house rather than actual consumption, which is subject to change depending on the number and behavior of residents of a home.

Annual Cost of Convention Natural Gas Heating

The Daily Water Heating Energy, the efficiency of the conventional heater, and the price of fuel all play a role in how much fuel is used for conventional heating on an annual basis. Estimated yearly cost of operation = (365 days/year) * (Daily Water Heating Energy therms/day)41,045 UEFSEF UEFSEF UEFSEF UEFSEF UEFSEF As an illustration, use the following benchmark values for daily energy consumption: UEF of 0.64 and a natural gas price of $1.10/therm: OR(365 days/year) (0.4105 therms/day) (0.64 USEF) ($1.10/therm) OR(365 days/year) (0.4105 therms/day) therm) = $257.52/year (estimated yearly running cost) Fuel Cost (therm) Example: Given a SEF of 1.1 and a per-therm cost of $1.10, the total cost of the gas is 365 x 0.4105 x 1.1 = $149.83.

Based on the DOE hot water heater test procedure, the energy consumption per day in the above equations is based on an incoming water temperature of 58°F, a hot water temperature of 135°F, and a total hot water production of 64.3 gallons per day, which is the average consumption for a household of three people.

WITH AN ELECTRIC AUXILIARY TANK SYSTEM:

You must know or be able to convert the unit cost of power expressed in kilowatt-hours (kWh). In 2021, the average electricity rate in the United States will be 10.42 cents per kilowatt-hour. With an average power rate of 30.55 cents per kilowatt-hour, Hawaii has the highest average electricity rate in the world. The average electricity rate in Louisiana is 7.01 cents per kilowatt-hour, making it the state with the lowest average power rate. With a UEF of 1.0 and an electricity price of $0.1042/kWh, the following is an example of Annual Water Heating Costs for an electric water heater:Annual Water Heating Cost = (365 days/year) x 12.03 kWh/day x (1.0) SEF x ($0.1042) = $457.54/year (assuming a UEF of 1.0 and an electricity price of $0.1042/kWh).

  1. Solar water heaters that are active
  2. Solar water heaters that are passive

Each of these functions differently and is comprised of separate pieces of equipment.

Active solar water heaters

In active solar water heaters, a pump is used to move hot water from the solar collectors or absorbers to the rest of the house. These are often seen in colder locations, as the water is stored in a tank that can be kept indoors to avoid freezing during the winter. There are two basic types of active solar water heaters: passive solar water heaters and hybrid solar water heaters.

  • Active solar water heaters move hot water from solar collectors or absorbers to your residence with the use of a pump. Due to the fact that the water is held in a tank that may be kept indoors to avoid freezing, they are typically seen in colder climes. In terms of active solar water heaters, there are two main types:

Passive solar water heaters

Passive solar water heaters do not require the use of circulating pumps to transfer the hot water around the tank. The use of convection as the water circulation mechanism, in which hotter water rises to the surface and colder water descends, allows them to circulate water more efficiently. Passive solar water systems are often less expensive than active solar water systems since they do not necessitate the purchase of additional equipment to pump the water. Passive solar water heaters are often classified into two categories:

  • It is possible to use an integral collector solar water heater to heat a significant amount of black water stored in an isolated box with a lid that allows sunlight to pass through. When you need hot water, the sunshine heats the water directly in the black tanks, which then flows into your plumbing system. Thermal collectors made of metal flat plate collectors are used to heat small batches of water on your roof using passive thermosyphon systems. When you turn on your hot water valves, hot water from the top of the batch collector flows down from your roof to your faucets, saving you money on energy costs. These are typically built to hold 40 gallons of water
  • However, some are smaller.

The use of a tankless heater as a backup energy source is common in passive systems, and these heaters can be either gas or electric.

What are the most popular brands of solar water heaters?

An increasing number of firms are developing solar heaters to take advantage of the expanding applications of solar technology in our daily life. These are some of the most popular models currently available on the market.

How to select the right solar water heater

Depending on the environment, some types of solar water heating systems perform better than others.

  • Direct systems are most effective in climates where temperatures rarely fall below zero degrees Fahrenheit. Cold conditions make indirect active systems more resistant to freezing damage than direct active systems. Do you want your solar heating system to serve a dual purpose? Make an investment in a system that circulates indirectly. During the intervals between supplying your house with warm water and heating your swimming pool or spa, the heating fluid may be diverted to do so. Families who use more hot water during daylight hours benefit from passive systems that are integrated into the home. Family members will not have to worry about running out of hot water for morning showers because of the ability to produce many tiny batches of warmed water. Do you have more roof space than you do ground space? A thermosyphon solar water heater is designed to be installed on your roof, allowing you to have more room in your living area. Because integral collector storage systems can weigh more than 400 pounds, you must ensure that your roof is capable of supporting the weight of a large water tank.

Furthermore, you must take into account the amount of sunshine that your home receives, how much hot water you use on a daily basis, and your financial situation. In your search for solar water heater choices, seek for ratings from the Solar Rating and Certification Corporation (SRC Corporation) (SRCC). Ratings from the SRCC make it simple to evaluate different brands and models by relying on professional third-party data. Because every home is different, you should obtain professional advice to ensure that you select the most appropriate system for your residence.

How much money can you save with a solar water heater?

Solar water heaters demand a significant initial cost – in some circumstances, upwards of $5,000 – to be installed. However, following installation, a solar hot water system will gradually begin to pay for itself by reducing the amount of money that is spent on energy bills. In fact, solar hot water heaters may often reduce your water heating expenditures by 50 percent to 80 percent, depending on your location. Your solar water heater will continue to provide almost free hot water for the rest of its useful life once you have reached the end of your solar payback period.

Always keep in mind that, depending on how much hot water your household consumes, you may be required to employ a backup grid-connected hot water system. The following information will be required in order to determine your potential savings:

  • What amount of hot water your household need on a daily basis
  • Fuel costs for your backup heater are calculated as follows: For additional information on the energy expenses associated with backup heaters, contact your local utility company. The SRRC, also known as the solar energy factor rating, of the equipment you want to use. These figures offer you an indication of how efficiently your appliance will utilise solar energy gathered
  • How much of your hot water consumption occurs during daylight hours
  • And how much of your electricity consumption occurs during daylight hours. Using more hot water when there is less sunlight available implies relying more on expensive grid electricity. Your solar water heating system’s expected lifespan is given below. The longer the life expectancy of your heating system components, the more money you’ll save.

You can calculate the annual running cost of your solar water heater using the information you have gathered. When you compare this to your typical monthly utility expenditures, you can see how much energy you could save by converting to solar power.

What rebates and incentives are available for solar water heaters?

Installing a solar water heater is eligible for a tax credit equal to 26 percent of the costs of doing so under the Investment Tax Credit, often known as the federal solar tax credit. For example, let us assume that your solar water heater costs $5,000. You’ll receive a tax credit of $1,300, which will reduce the total cost of your system to just $3,700, saving you money. In addition, your local utility provider may provide special discounts or rebates for the installation of eligible equipment, depending on their policies.

Should I get a solar water heater or a home solar panel system?

Until a few years ago, solar water heaters were a popular choice for many people. Instead, the current tendency is for homeowners to simply install a solar panel system on their property. Why? Because the price of solar panels has dropped significantly in recent years. When it comes to cost-effectiveness, pairing a domestic solar panel system with an electric water heater is the best choice. Not only will the solar panel system cover your hot water expenditures, but it will also cover the energy costs of your whole home.

  1. Solar water heaters, on the other hand, can be beneficial in some situations.
  2. Only the water must be heated by the sunshine; it does not need to be converted into energy, which would then power a system to heat the water.
  3. Solar hot water heaters may be the ideal option for you if you have limited space and want to maximize the benefits of solar energy.
  4. They’ll also be able to assess which option is ideal for you – whether to obtain just one or both of the options.

Key takeaways

  • Solar water heaters, which use solar energy to heat water with the assistance of solar collectors on your roof, are becoming increasingly popular. Water heaters that are active in the solar energy system utilize a pump to circulate hot water from the solar collectors to your residence. Instead of using pumps to circulate the water, passive solar water heaters use convection to do this. It is possible to spend up to $5,000 on a solar water heater that can reduce your hot water heating expenditures by half. Renewable energy systems such as solar hot water heaters are eligible for the federal solar tax credit. Additional incentives from local governments and utility providers may be available.

Adding a solar water heater to your existing water heating system can save you thousands of dollars over the long term in water heating costs and energy. As an added bonus, it will help to extend the life of your existing water heater. Let us not lose sight of the fact that solar energy is a renewable energy source.

Any time you can put solar energy to use, you are contributing to the preservation of the environment. It is possible to buy active sun water heaters and passive solar water heaters. Active solar water heaters are the more common type. The following two categories are discussed in further detail:

Active Solar Water Heaters

With an active solar water heater system, copper tubing is connected to a solar panel on the roof, which is located either above your water heater tank or above a separate tank (in the event of a two-tank system). The tank cycles the water up to the solar panel, where it passes through the solar panel, where the water is heated, and then transmits the water back to the water heater or to another tank.

Passive Solar Water Heaters

A passive solar water heater system does its work by heating water stored in a tank on the roof. It does not require a sequence of solar panels to circulate the hot water through the system; instead, it uses sunlight to do it. They are the preferred method because to the ease with which they can be installed and the durability with which they are built. Its sole disadvantage is that the passive tank on the roof must be in close proximity to the storage tank that circulates the water in order for the system to work properly.

If you live in a climate with a chilly winter and significant temperature fluctuations, a thermosyphon system is what you need.

ICS systems are intended for use in temperate areas.

Solar Water Heater Prices

Recent technological advancements have made solar water heaters both more affordable and more efficient, and fresh advancements are being developed on a daily basis. In order to determine the cost of building such a system, a variety of variables must be considered. This list of variables includes factors such as geographic location, climate, kind of system, type of roof, and tank capacity.

Active Solar Water Heater Prices

Approximately 20 to 25 gallons of water per person are used by a typical household in the United States. In the case of a typical four-person family, a system that can heat 100 gallons of water each month will cost between $8,000 and $10,000, depending on the size of the system and its location. It is possible that you will spend as much as $12,000 to $15,000 on a system that satisfies your demands if your water use is higher than typical and you require a larger tank and additional solar panels.

Passive Solar Water Heater Prices

A passive solar water heater system is often less expensive than an active solar water heater system, both in terms of components and in terms of installation. There is no need for solar collectors, and the pipe required for installation is less expensive. The cost of a passive solar water heater system, assuming the same 4-person typical home as in the active scenario, will range between $5,000 and $8,000, depending on the technology. When it comes to passive systems, there isn’t much of a price difference between the two types (ICS and Thermosyphon solar water heaters).

Tax discount for Solar Heaters

Both in terms of material costs and in terms of installation costs, a passive solar water heater system is often less expensive than an active solar water heater system. It is not essential to use solar collectors, and the pipe required for installation is less expensive than with traditional solar technology. In the active situation, you may expect to pay between $5,000 and $8,000 for a solar water heater system.

In the passive scenario, you can expect to pay between $5,000 and $8,000. When it comes to passive systems, there isn’t much of a price difference between the two options (ICS and Thermosyphon solar water heaters).

Labor Cost $70 8-24 $560-$1,680
Total Cost $2,560-$5,680 each 1 $2,560-$5,680

Other considerations and costs

  • Because of the possibility of running out of residential hot water supplies, passive systems are often linked with a high level of expenses. The backup heater, switches, and all of the necessary piping to connect the system to a tank are all included in one package. These fees can easily exceed $1,000 and can reach as high as $4,000 in some instances. With a solar water heater, you can also heat your spa or pool, and the cost of the system is typically between $3,000 and $4,000, which is not significantly more expensive than a regular pool heating system. It is also important to consider where the collector will be installed in the home, since this has a considerable influence on the overall cost of the project. Because of the sluggish labor rates, as well as the need for a ladder and roof work, it will be more efficient when mounted to the roof
  • Nonetheless, the cost of labor may be prohibitively expensive. Tax credits are frequently given to such initiatives, and they can be worth up to 30 percent of the entire cost, or $2,800, depending on the circumstances. Incentives from the state and municipal governments may be available, and there is also the benefit of lower energy bills. It is common for the payback time on this investment to begin between three and six years after the initial expenditure.
