Common Questions
How long do solar panels last?
Most solar panels are warrantied for 25 years and continue producing at 80-90% efficiency after that. Many systems last 30-40 years with minimal degradation.
Do solar panels work on cloudy days?
Yes, but at reduced efficiency (10-30% of full sun output). However, net metering credits from sunny days offset cloudy periods.
Will solar panels damage my roof?
No, when properly installed. Quality installers use flashing and sealants that protect your roof. Many warranties cover roof penetrations.
What happens when I sell my home?
Studies show solar adds $10,000-$30,000 to home value. Owned systems transfer with the home. Leased systems require lease transfer or buyout.
Do I need to clean my panels?
Most rooftop systems are cleaned by rain. In dusty areas, annual cleaning may improve output by 1-5%. Avoid high-pressure washing.
