Solar photovoltaic (PV) panels are one of many renewable energy technologies available for homeowners. There are many ways to incorporate solar energy into your home, from installing a residential solar system to installing skylights or joining a community solar program.

While you can go the traditional route of installing solar panels on your roof, there are also alternative ways to incorporate solar energy into your home.

Solar energy is extremely abundant. According to the National Renewable Energy Laboratory(NREL), the sunshine reaching the planet every hour has enough energy to cover global consumption for an entire year. Homeowners and businesses can use solar technology to convert that energy into electricity.

Using the power of the sun can provide both financial and environmental benefits. Traditional power plants and water heating systems rely on fossil fuels, and electricity prices can fluctuate based on your utility company. Alternatively, you can use sunlight to generate electricity or provide direct heating for your home, offsetting electricity costs and releasing zero emissions in the process.

There are many solar technologies, but homeowners have three main options at their disposal:

While you can use solar panels to power your entire home, full system installation can cost between $15,000 to $20,000. Homeowners with solar panels can normally achieve a payback period of less than 10 years, depending on their location, local electricity rates and available solar incentives. But if you don’t have rooftop space for solar panels or prefer to avoid the upfront cost, there are several alternatives to using solar energy:

There are multiple options for using solar energy to power or light your home. We outline some of the most common uses of solar energy for homes below.

Installing a solar power system is the most effective way to power your entire home using solar energy. The best solar panels can last more than 25 years, providing your home with clean energy and utility bill savings for decades. However, solar panel systems include a high upfront cost.

According to our March 2023 survey of 1,000 homeowners with solar, it costs $2.85 per watt on average to install a solar panel system. Based on this figure, you could expect to pay around $14,250 for a 5 kilowatt (kW) system or $28,500 for a 10 kW system. In both cases, you can claim solar incentives like the solar Investment Tax Credit(ITC) to lower project costs.

If you’re considering solar energy but prefer to avoid a major investment, there are alternative technologies that come at a lower cost.

Solar water heaters use collector panels directly exposed to the sun’s rays to generate hot water for your home. The solar collectors use a heat transfer fluid such as ethylene glycol to capture thermal energy, which is then used to heat water for residential use.

The price of solar water heaters can range from $1,500 to $13,000, depending on the size and complexity. Large solar water heaters compare to PV panels in terms of price, but small units are more affordable.

Generally, passive solar water heaters are more affordable than solar panel systems but have a longer payback period. According to a cost analysis by the U.S. Department of Energy, the payback period of solar water heaters can exceed 10 years.

In warm climates, a solar water heater can potentially cover 100% of your hot water needs. However, you may need an electric or gas-fired heating system as backup in colder locations.

Solar energy systems are available in all sizes. You can invest in a large rooftop system to generate electricity for your entire home or you can use a portable solar kit to power small appliances.

Based on our research, there are portable solar generators with built-in batteries and power outlets priced below $2,000. Smaller systems cannot provide enough power for HVAC equipment or refrigerators, but you can connect small devices such as LED lights and smartphone chargers.

The large solar panels used for rooftop and ground-mount systems are designed for professional installation. Since portable solar kits have lower voltages and power ratings, they are suitable for DIY installations.

You can also use small solar panels to power outdoor sheds and light fixtures, instead of having to wire long circuits between your main panel and outdoor areas. Based on our market research, you can find outdoor solar lights with built-in PV panels and batteries below $100. There is a wide range of lighting products available, including solar security lights and rechargeable flashlights.

Using solar energy is not limited to home heating and electric power generation. The sun is also a source of free natural lighting, which you can utilize inside your home. For example, you can install skylights or solar tubes to allow sunlight into your home while reducing solar heat gain. While LED bulbs consume up to 90% less electricity than traditional lamps, solar skylights have zero energy usage.

The cost of solar tubes and skylights varies depending on their design. You can find basic solar tubes with an installed cost of around $500, while large skylights can exceed $2,000.

Some energy consumers may not have the option of installing solar panels, including renters without a private roof area or people without adequate roof space. In these cases, you can join a community solar project instead of purchasing your own panels.

Community solar systems are shared by many electricity consumers who participate as shareholders or subscribers. The electricity generated by a community solar project is measured and split among participants based on their ownership share or subscription to the project.

Community solar systems also offer mobility for renters. If you move to another address while subscribing to a community solar project, you can assign your solar energy credits to your new power bill. This method is much simpler than having to relocate a rooftop solar system.

However, community solar power is not available everywhere. Check with your state or local government to see if you have access to community solar projects in your area.

Depending on where you live, you may have the option of choosing your electricity provider. For example, Texas has a deregulated power sector in which consumers can choose an electricity plan. In this case, you can look for energy plans that use 100% renewable energy. However, this option is only available in certain regions of the U.S.

Solar energy systems reduce your energy costs by lowering how much you use traditional utility services. The power generated by solar panels is subtracted from your electricity bills, and the heating provided by a solar hot water system is subtracted from your gas bills. You can also use solar lighting to harness natural light, lessening your reliance on electricity.

Solar technologies can achieve better results when combined with energy efficiency measures like using LED lighting or adding insulation. In this case, you can achieve energy savings from both efficiency measures and solar power generation.

There are many types of renewable energy systems you can deploy to power your home, but solar energy offers several advantages. Solar panels have simple maintenance needs, and you can combine your panels with a battery storage system to achieve a continuous power supply. Solar panels also have a long lifespan of 25 to 30 years, and leading solar brands offer a 25-year product warranty to handle manufacturer and performance issues.

The most efficient solar panels can convert around 20% to 23% of the sun’s energy into electricity. However, adequate panel positioning is key to achieving a high energy output. Solar cells will not perform as well in shaded areas. Professional solar installers can ensure your panels are placed at a tilt angle that maximizes exposure to sunlight.

The cost of solar energy systems varies widely depending on the specific technology and system size. A portable solar generator can cost you less than $1,000, but a large rooftop array with a home battery can surpass $30,000 before incentives.

In the case of traditional solar systems, there are four main payment options:

Generally, you will see the highest return on investment with a cash purchase or solar loan. You also own your solar system under both financing methods and can claim solar incentives to lower your overall cost.

With a solar lease or PPA, you essentially rent a solar system from a provider. A solar PPA is similar to a lease but instead of paying a monthly fee to use the solar panels, you pay an agreed price per kilowatt-hour for the energy generated. While PPA prices are set lower than local electric tariffs, you will never own the system and cannot claim certain incentives like the federal solar tax credit.

Leases and PPAs are only available for solar panel systems that have several kilowatts of capacity. You generally cannot use a lease or PPA to purchase a portable solar kit or non-photovoltaic equipment such as solar water heaters and skylights.

You can find many financial incentives for solar energy systems throughout the U.S., but different technologies qualify for different incentives. The solar federal tax credit is available for:

The 30% federal tax credit is available for solar energy systems installed on primary and secondary homes used directly by the owner, not rental properties. Solar water heaters qualify depending on the application — they are eligible when used for homes, but not when used in swimming pools. In the case of skylights, there is a maximum tax credit of $600.

Depending on your location, additional incentives may be available from government agencies or electric utility companies. You can visit the Database of State Incentives for Renewables and Efficiency(DSIRE) to read about the solar incentive programs available near you. The database also covers other renewable sources and energy efficiency measures.

Solar technology can be a worthwhile home investment if you want to use clean energy to lower your power bills. While a traditional solar system can power your entire home, solar installation represents a major investment of over $15,000 before incentives. If you are looking for a more affordable project, you can consider other solar technologies such as:

The cost of these technologies varies but is generally much lower cost than a rooftop solar system. For example, you can find portable solar generators for $1,000 to $2,000 or less. Regardless of the technology you choose, investing in solar energy offers both financial and environmental benefits such as lowering your electricity costs and offsetting fossil fuel use.

If you choose to install a solar system, high-quality solar panels come with 25 product warranties on average, with a typical payback period of less than 10 years. The best solar companies also offer installation and workmanship warranties for added protection.

The three most common uses of solar energy include generating electricity with solar panels, using solar thermal collectors to heat water and providing natural lighting for buildings. You can invest in various technologies to achieve the above uses of solar energy, including solar panels, solar water heaters and sun tubes.

There is a wide range of solar technologies that you can use for your home, including:

The cost of solar technologies varies depending on what you purchase. For example, solar panel systems can cost upwards of $15,000 to $20,000 while portable generators can cost $2,000 or less.

We recommend contacting a qualified solar installation company if you want to purchase a solar panel system. An installer can determine the ideal number of solar panels for your home based on your monthly power bills, sunlight conditions and energy needs. Opting for a professional installation is also safer due to the height of your roof and electrical wiring requirements.

You can also find DIY solar kits designed to power small appliances off the grid. While you can typically install small solar kits yourself, they are not meant to generate electricity for an entire home. However, you can use DIY solar kits to power a camper van or tool shed.

Generating your own electricity with solar panels or other renewable energy systems can help lower your carbon footprint. You can also reduce fossil fuel consumption with eco-friendly technologies and home upgrades such as LED bulbs and energy-efficient air conditioners.
