“No moving parts” is not the same as “no maintenance.” Arizona dust cuts production all spring, 115° heat cycling loosens connections all summer, monsoon tests every roof penetration, and pigeons work year-round. Here is what maintenance actually involves, what you can do yourself, and what a professional plan costs.

Arizona is simultaneously the best place in America to own solar and one of the hardest places on the equipment. Four things erode a system here, and none of them announce themselves:
DIY: glance at your monitoring app weekly (a five-second habit that catches most failures), keep an eye out for birds gathering on the roofline, and hose panels from the ground at dawn if you must — never with a pressure washer, never on hot glass. Not DIY: anything involving walking the array, opening electrical equipment, or the roof penetrations. String voltage is live whenever the sun is up, and tile breaks under people who do not walk it daily.
Panel cleaning companies clean glass. Solar installers check electronics. Almost nobody inspects the mounts, flashing and sealant holding the array through your roof — the single place where a neglected solar system turns into a five-figure interior repair. We are an Arizona Roofing Contractors Association board member; every maintenance visit we run inspects the roof under the array, every time.

The SolarCare Plan is maintenance as a subscription: two scheduled visits a year — typically before and after monsoon season — each including performance verification against expected output, a full written inspection report, professional panel cleaning, and the roof-and-mount inspection nobody else does. Around it: priority scheduling, a technician on site within 48 hours in an emergency, and 10% off any repair.
The arithmetic: our standalone inspection is $299, so two visits at list would be $598 before cleaning, the roof inspection or any of the membership benefits. Prefer one-off? A single $299 inspection is the right first step for a system that has never been checked — the first visit usually finds something, and better us than the monsoon.
