Solar Panel Repair and Inverter Diagnostics in El Cajon
If your solar system in El Cajon has stopped producing, shows an inverter error, or was installed by a company that is gone, we diagnose it and tell you plainly what is wrong. The first evaluation is free.
What we do in El Cajon
We diagnose and repair existing solar systems (inverters, panels, optimizers, wiring, monitoring) and add Tesla Powerwall batteries to existing systems. You do not need to have bought your system from us.
Your utility decides what upgrades are worth
This area is served by SDG&E and is not in a community choice program, so your bill and rate plan come straight from SDG&E. That makes the bill itself the first thing we look at.
What is hard on solar here
Inland heat is hard on inverters and connectors. Many systems here run hot every summer, and a fault can sit unnoticed because the roof is still making plenty of power on a sunny day.
