What we do not handle
- Solar installation quotes. We are not a solar installer or referral broker. For quotes, contact local installers directly or use a marketplace like EnergySage.
- Engineering review of specific projects. Calculators give estimates only — site-specific design must come from a licensed engineer or installer.
- Refund or warranty issues with solar equipment. Contact the manufacturer or installer who sold you the equipment.
