Today's Homeowner looks at dozens of datapoints on solar companies to come up with our data-driven rankings. It's not possible for a company to pay for preferential treatment in our rankings. We look at the following key factors in determining who should top our list:
Installing solar panels can cut your electricity costs and help the environment by reducing your carbon footprint. When determining whether a solar provider is the best option for you, consider these key factors.
It's important to hire a licensed solar installer. This help guarantee that the work is done correctly using the most up-to-date installation methods. While electricians and plumbers in Colorado have state-issued licenses from the Colorado Electrical Board or Colorado State Plumbing Board, the state's unique home-rule structure means counties and cities can issue their own solar professional if they choose.
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 evaluate a company's dependability and customer service. Use caution with companies that have barely any reviews or mostly negative ones.
Get free, detailed quotes from at least three solar companies. A quote should outline all costs and identify the exact solar parts included. Comparing several quotes can help you find the option that best fits your budget.
High-quality solar installations should come with robust workmanship and performance warranties. The workmanship guarantee covers any installation issues like poor wiring, poor alignment, or cracks in the panels. The output warranty guarantees an energy generation baseline. Strong warranties reflect a solar provider's confidence in its installations.
Solar panels can help decrease your electricity costs over time. When considering solar panel's cost and value, be sure to factor in these considerations.
