How To Choose a Solar Company

Putting solar panels on your roof could lower your electricity payments while benefiting the planet by reducing your carbon footprint through renewable energy use. Key considerations when looking at local solar installers are as follows.

Check Licensing

Hiring a licensed solar installer is critical. This ensures that the work is done correctly using current best installation practices. While electricians and plumbers in Colorado have state-issued licenses from the Colorado Electrical Board or Colorado State Plumbing Board, counties and cities can issue their own solar professional if they choose.

Read Customer Reviews

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

Compare Multiple Quotes

Get free, detailed quotes from three to five solar companies. A quote should list all costs and identify the exact solar parts included. Comparing several quotes can help you find the option that best fits your budget.

Ask About the Warranty

Quality solar installations should come with strong workmanship and performance warranties. A workmanship warranty addresses any installation defects (such as poor wiring, cracks in the panels, or poor alignment), while a performance warranty ensures a certain level of energy production. Strong guarantees demonstrate a company's confidence in its work.

Evaluate Financing and Incentives

Switching to solar power can help decrease your energy expenses over time. Be sure to consider these aspects when determining the cost and value of solar panels.

  • Compare system purchase options: Solar panels can be purchased outright or financed over time with leases or loans. Verify key financing details like fees, payment schedule, annual percentage rate (APR), and ownership implications when financing solar panels.
  • Look into utility rebates: Local utility companies may offer additional rebates to encourage homeowners to install solar panels. Check the eligibility rules and rebate values with your local utility provider to determine what your savings could be.
  • Research federal and state tax credits: There’s a 26% federal tax credit available for the full cost of solar systems until 2032. Many states also provide incentives. The credits can result in significant savings for solar buyers.

Cost of Solar Installation in Thornton

The average Thornton homeowner will spend around $14,488 on a home solar system after federal tax refunds.

Some homeowners prefer to lease solar panels in order to reduce upfront costs.

Although solar energy is a great option for many, it might not be ideal for homeowners in wet, dark areas.
