How To Choose a Solar Company

Going solar can be a great way to save money on electricity costs and help the planet by reducing your carbon footprint using renewable energy. Here are some key factors to consider when deciding if a solar installer is reliable.

Check Licensing

Make sure you hire a licensed solar installer. This help guarantee that the work is done correctly using the most up-to-date installation methods. Since 2012, Virginia's Department of Professional and Occupational Regulation has issued Alternative Energy Systems (AES) licenses to contractors who install solar PV systems. A contractor with an AES license may need to subcontract HVAC, plumbing or electrical work.

Read Customer Reviews

Check review sites like TrustPilot, the Better Business Bureau (BBB), and Google Reviews to see feedback from past customers on local solar companies. Detailed reviews can help you assess a company's reliability and customer service. Use caution with companies that have very few reviews or mostly negative ones.

Compare Multiple Quotes

Call at least three solar companies for free, itemized quotes. A quote should outline all costs and specify the solar equipment included. Reviewing multiple quotes helps you find the best option that fits your budget.

Ask About the Warranty

Top-notch solar installations should have strong workmanship and performance guarantees. A workmanship warranty covers installation issues, such as poor alignment, cracks in the panels, or poor wiring. A performance warranty ensures a minimum energy output. Comprehensive warranties indicate that a solar company believes in its work.

Evaluate Financing and Incentives

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

  • Research federal and state tax credits: A 26% federal tax credit for the full solar system cost is available through 2032. Many states provide incentives, too. The credits can result in substantial savings for solar buyers.
  • Compare system purchase options: Solar panels may be paid for outright or financed through loans or leases. Check 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 financial incentives might be available from electric companies looking to motivate homeowners to install solar panels. Contact your local utility provider to learn rebate values and eligibility rules, so you can determine your possible savings.
