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

Verify that your solar installer is properly licensed. This ensures that the work is done properly using current installation best practices. Delaware treats solar installation no differently from any other electrical work. Solar contractors must be licensed electricians, and the government recommends they apply for certification from the North American Board of Certified Energy Practitioners (NABCEP) on top of their license.

Read Customer Reviews

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

Compare Multiple Quotes

Get free, detailed quotes from 3–5 solar companies. The quotes should outline all costs and identify the exact solar parts included. Looking at several quotes can help you find the best value for your budget.

Ask About the Warranty

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

Evaluate Financing and Incentives

Solar power can help decrease your electricity costs in the long run. When considering solar panel's cost and value, be sure to factor in these considerations.

  • Research federal and state tax credits: There’s a 26% federal tax credit available for total solar system costs until 2032. Many states also offer incentives. The credits can result in significant savings for solar buyers.
  • Compare system purchase options: Solar panels can be purchased upfront or financed through leases or loans. Confirm important financing details such as payment schedule, annual percentage rate (APR), fees, and ownership implications when financing your solar system.
  • Look into utility rebates: More discounts might be available from utility companies looking to encourage homeowners to switch to solar power. Contact your local utility provider to learn rebate values and qualification criteria, so you can calculate your possible savings.

There are many advantages of home solar energy. You can qualify for tax benefits, reduce emissions, and raise your property values. With the right storage equipment, solar panels can also offer you additional energy security and offer some protection from power outages.

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

With net metering programs offered by many utilities, you could ultimately make a profit from your system when your payback period is done.

While solar energy is an ideal option for many, it might not be ideal for homeowners in wet, dark areas. In these cases, you could consider other forms of renewable energy, such as wind or geothermal power, as a primary source. It is also important to speak to a qualified installer to determine if their solar system is compatible with the climate and environment of your area. Even if you choose a different form of renewable energy altogether, you'll still help the environment and could still qualify for distributed generation or other money-saving programs.

Solar panels are becoming more popular for their low upkeep costs and high efficiency under a variety of conditions. Depending on how much sunlight your property receives, you may find they're the best performing source of renewable energy compared to others.
