Frequently Asked Questions
Do I need a permit for a residential solar system in Zion?
Yes. The City of Zion requires a building permit and an electrical permit for any system over 1 kW. A qualified installer will handle the paperwork.
Can I install solar on a metal roof?
Absolutely. Most installers use ballasted mounting systems that attach without penetrating the roof, preserving warranty and minimizing leaks.
What happens if my utility goes down?
Standard grid‑tied systems shut off automatically for safety. To retain power during outages, add a battery storage system (e.g., Tesla Powerwall) – many installers offer bundled packages.
How long will my panels last?
Most panels carry a 25‑year performance warranty guaranteeing 80% output at year 25; actual lifespan often exceeds 30 years with proper maintenance.
