Solar not working?
Start here.

Safe, step-by-step checks for the most common home solar problems, by symptom and by brand, with links to each manufacturer’s own guidance.

By symptom

Low productionSolar Panels Not Producing Enough?“Less than expected” needs a fair comparison first. Here is how to check your system against the right baseline before calling anyone.Sudden dropSolar Production Dropped Suddenly?A sudden drop is usually easier to trace than a slow decline, because something changed on a specific day. Find that day first.Monitoring offlineSolar Monitoring App Offline? What to DoAn offline app usually means the system lost its internet link, not that the panels stopped. Restore reporting first, then check production.Health checkHow to Tell If Solar Panels Are WorkingFive checks you can do in ten minutes without tools, without a ladder and without opening anything.WinterSolar Panels Producing Less in Winter?Lower winter output is expected. The question is whether it is lower than last winter. Here is how to tell.Orphaned systemSolar Installer Went Out of Business?Your equipment warranties usually come from the manufacturer, not the installer. Here is how to keep monitoring, warranty and service on track.

By brand

EnphaseEnphase Not Reporting? Envoy Offline FixesAn Envoy or IQ Gateway that is offline usually means a lost internet connection, not dead panels. Here is what Enphase says to check, in a safe order.SolarEdgeSolarEdge Inverter Error Codes ExplainedMost SolarEdge error fixes are for qualified installers. Here is how to find the code, what SolarEdge says the common ones mean, and what you can safely do.TeslaTesla Solar Not Producing? What to CheckZero production in the Tesla app can be a real inverter problem, a data problem, or normal Powerwall behaviour. Here is how to tell them apart safely.SMASMA Inverter Error? Event Codes ExplainedSMA inverters report problems as numbered events. SMA’s manuals say what each one means; most fixes are for a qualified person, not the homeowner.

Before you start

Most problems fall into three groups: the system stopped reporting (internet or gateway), it stopped or reduced producing (inverter, breaker, shade, snow or a fault), or production is normal for the season but looks low. The guides above help you tell which one you have. Try the underperformance check for a quick comparison.

Safety first

Only do the checks on this page that need no tools: read the app, look at the inverter or gateway lights, reset a tripped breaker that is labelled for the solar system or gateway, and look at the array from the ground. Never open an electrical panel, inverter, combiner or junction box, never touch wiring or connectors, and never climb onto the roof. Solar equipment can stay energized while the sun is up even when the grid is off. If a breaker trips again, you smell burning, or you see scorch marks, water in equipment or damaged wiring, stop and call your installer or a licensed electrician.

Tell us which monitoring app your system uses (Enphase, SolarEdge, Tesla, SMA, Fronius, Generac or another brand). We send you the steps to add our team as a viewer or installer from inside the provider’s own app. You never share your password with us. Once access is granted, our team connects your system and runs a free remote review of your production and alerts, then tells you what we found and the next step.

  2. 02Grant viewer or installer access in your app
  3. 03Our team reviews it and reports back

Remote data can show when and where production changed, but it cannot always find the physical cause. Some issues need an on-site visit or your installer. We never ask for your monitoring password.
