How To Choose a Solar Company

Adopting solar power lets homeowners lower utility bills while helping the environment by reducing your carbon footprint using clean energy. If you’re deciding whether to go solar, consider these key factors for choosing an installer.

Check Licensing

It's important to hire a licensed solar installer. This ensures that the work is done properly using current installation best practices. To install solar energy systems in Washington, D.C., a contractor must have a license in the trade for which the system is designed. Photovoltaic installers must be licensed electricians through the Department of Licensing and Consumer Protection, solar HVAC installers must have an HVAC license and solar water heater installers must be licensed plumbers.

Read Customer Reviews

Check Google Reviews, TrustPilot, the Better Business Bureau (BBB), and other review sites to see what past customers are saying about local solar installers. Detailed reviews on these platforms can help you evaluate a provider's trustworthiness and customer service. Stay away from companies with few or mainly poor reviews.

Compare Multiple Quotes

Contact 3–5 solar companies for free, detailed quotes. Quotes should clearly outline all costs and specify the exact solar components included. Comparing multiple quotes helps identify the most cost-effective option for you.

Ask About the Warranty

Quality solar installations should have comprehensive workmanship and performance guarantees. The workmanship warranty covers any installation issues such as poor wiring, cracks in the panels, or poor alignment. The performance guarantee ensures a specific energy output level. Strong warranties indicate that a solar installer has faith in its installations.

Evaluate Financing and Incentives

Solar energy is great for helping you lower electricity bills over time. Make sure you consider these aspects when considering the final cost and value of solar panels.

  • Look into utility rebates: More rebates might be available from local power companies looking to encourage homeowners to install solar panels. Contact your local utility provider to learn rebate values and qualification criteria, so you can determine your possible savings.
  • Compare system purchase options: Solar panels can be purchased outright or paid for over time through a lease or loan. Review all terms when financing, such as fees, payment schedule, annual percentage rate (APR), and ownership implications.
  • Research federal and state tax credits: A 26% federal solar tax credit on the full system cost is available through 2032. Many states also offer incentives. These credits provide substantial savings for solar customers.

Cost of Solar Installation in Washington

The cost of solar panels varies based on your system's capacity and the technology being used. The typical Washington solar array has a capacity of 8.4 kilowatts. Homeowners in the area should expect to pay around $3,540 per kilowatt; the average Washington homeowners spends about $20,713 on a new solar system after accounting for federal tax breaks. (Some homeowners prefer to lease solar panels to lower upfront costs.) A personalized quote from a local solar installer will account for things like the panel type, capacity, and size of the planned system, and should include prices for labor, permit fees, and preliminary work.

Frequently Asked Questions About Solar in Washington, DC

Generally speaking, a solar photovoltaic (PV) system can be used to power any household appliance or system that uses electricity. In the simplest case, you can use a solar water heating system.

With home solar energy, you can recoup the cost of the system over time, lower your home's carbon footprint, and be better prepared if there's an outage to the local grid.

It depends on your home's location and what type of panels you're installing. Since there's a moderate amount of snowfall in Washington, your best time to install solar panels is in the spring and fall.

Your payback period is the time to achieve an ROI on your solar panels. It will vary based on their rated capacity, the rate your utility charges per kilowatt of power, and the average sunlight in your area. Washington gets quite a bit of sunlight per day, so an average payback period could last up to 19.1 years per 5 kW of capacity.

The specific required maintenance steps will vary based on the type of solar panels you have. With any system, you should clean and inspect each panel once a quarter. Your solar energy company might offer comprehensive plans where they'll do the maintenance for you.

While solar energy might not be the best option for some in wet or dark areas, the latest generation of equipment and energy storage systems could boost your property's solar viability enough where you could achieve a return on investment. A contractor could also recommend a different primary source of renewable energy like wind or geothermal to boost your generation.

When it comes to taxes, the federal government offers a tax credit of up to 30% of the panels' cost. Depending on where you live, you could also claim or apply for state or property tax incentives. Regarding insurance, your monthly premium may be slightly higher because solar panels increase your property's value. You should talk with your accountant or insurance agent for information specific to your case.
