Frequently Asked Questions

Everything you need to know about choosing a solar company
Look for licensing, warranties, customer reviews, and experience. Avoid pushy sales tactics and compare at least 3 quotes.
Customer reviews show how a company treats people. Expert ratings show how well they do the technical work.
National companies offer stability and scale. Regional companies offer local expertise and personal service.
In the USA, solar installation typically costs $15,000–$25,000 before federal tax credits (30% ITC brings it down to roughly $10,500–$17,500 after credit).
Three warranties: equipment (10–25 years), performance (25 years), and workmanship (5–10 years).
1 to 3 months total — permitting and paperwork take most of the time. Actual physical installation is only 1 to 3 days.
