If your solar system stops producing, check from the ground for a tripped solar breaker, an off AC disconnect, inverter error codes, and a lost monitoring connection. Don't climb on the roof or open equipment. Inverter failures, wiring faults, and critter damage are common repairs, and manufacturer warranties may still apply even if your installer is gone.

Solar panels have no moving parts, but systems still fail. Inverters wear out, wiring gets damaged, critters chew cables, and storms take their toll. A drop in production can go unnoticed for months if no one is watching. And because some solar companies have gone out of business, many Atlanta homeowners own "orphaned" systems with no installer to call.
Signs your system needs attention
- Your monitoring app shows zero or much lower production than the same month last year
- Your electric bill jumped without a change in usage
- The inverter displays an error code, a red or orange light, or no display at all
- The monitoring app stopped reporting (sometimes just a Wi-Fi issue, sometimes more)
- Visible damage: cracked glass, loose panels, scorch marks, or dangling wires
- Squirrel or bird nests under the panels
Quick checks you can do safely from the ground
- Check whether the solar breaker in your main panel has tripped.
- Make sure the AC disconnect near your meter is on.
- Note any error codes or status lights on the inverter, and photograph them.
- Check whether your monitoring device lost its internet connection.
Don't climb onto the roof or open any equipment. Panels produce electricity whenever light hits them, and DC wiring can carry dangerous voltage even when the system is "off."
Common repairs
- Inverter replacement. String inverters commonly need replacement before the panels do. Microinverters and optimizers can fail individually.
- Wiring and connector faults. Loose or corroded connectors, chewed cables, and ground faults can shut a system down or create a hazard.
- Critter guards. Mesh barriers around the array's edge can keep squirrels and birds out from underneath.
- Panel replacement. A damaged panel may need to be replaced with a compatible model if the original is no longer made.
Do panels need cleaning?
In most of Metro Atlanta, regular rain does a fair job of keeping panels clean. Heavy spring pine pollen and debris from trees can build up, especially on low-tilt panels. If production drops noticeably after pollen season, a professional cleaning may help. Avoid pressure washers, harsh chemicals, and walking on panels, all of which can cause damage and void warranties.
Warranties
Check your paperwork before paying for repairs. Panels and inverters typically carry manufacturer warranties, and your installer may have offered a workmanship warranty. If your installer is out of business, the equipment manufacturer's warranty may still apply, though labor may not be covered. A service company can help you file a claim.
Leased systems
If you lease your system or buy power under a PPA, the company that owns the equipment is usually responsible for maintenance and repairs. Contact them first; unauthorized repairs could breach your contract.
If your system isn't producing, request a solar service company near you and choose "Existing system not working."
Frequently asked questions
Why did my solar system stop producing?
Common causes include a tripped breaker, an inverter fault, a wiring or connector problem, or damage from animals or storms. Sometimes only the monitoring stopped reporting. A qualified technician can diagnose it safely.
My solar company went out of business. Who can fix my system?
Many independent solar service companies work on systems they didn't install. Equipment manufacturers' warranties may still cover failed parts, though labor may not be included.
Do I need to clean my solar panels in Atlanta?
Rain usually keeps them reasonably clean, but heavy spring pollen and tree debris can build up. If production drops after pollen season, a professional cleaning may help. Avoid pressure washers and walking on panels.
