FAQHow do solar panel warranties work and what actually gets coveredPanel manufacturers typically guarantee 80 to 90 percent output for 25 years, while installers warrant labor and equipment for 5 to 10 years, but warranty coverage excludes damage from extreme weather, accidents, or improper maintenance.
Tips and mistakesWhat maintenance does a solar panel system actually requireSolar panels need occasional cleaning and a professional inspection every few years, but most systems require very little maintenance beyond replacing the inverter after 10 to 15 years.
Costs and pricingHow much money will I actually save with solar panels over 25 yearsCalculate savings by multiplying your average monthly electricity bill by 300 months, subtracting your installed cost and ongoing maintenance, but accuracy depends on local electricity rates, system efficiency, and how long you stay in your home.
FAQWhat happens to my electricity bill when solar panels produce more power than I useMost utilities credit your account for excess power your panels send to the grid at your standard retail electricity rate, though some areas offer lower compensation, so confirm your utility's policy before installation.
