Adopting solar power lets homeowners cut utility bills while benefiting the planet by reducing your carbon footprint using clean energy. If you’re deciding whether to go solar, consider these key factors for choosing an installer.
Verify that your solar installer is properly licensed. This help guarantee that the work is done correctly using current best installation practices. The Commonwealth of Pennsylvania does not issue state-level contracting licenses, so each city or county can set its own requirements and terms.

Detailed reviews on these platforms can help you assess a provider's reliability and customer service. Avoid companies with few or mainly poor reviews.
To find a solar company that fits your budget, ask for free, detailed quotes from three to five providers. The quotes should list all costs as well as all solar equipment included. Comparing several quotes helps you identify the best value.
Quality solar installations should have comprehensive workmanship and performance warranties. The workmanship guarantee covers any installation problems such as poor alignment, poor wiring, or cracks in the panels. The performance guarantee ensures a specific energy output level.
