If your solar panels have stopped working, the first step is to check the fuse. If the fuse is blown, you can replace it yourself. If the fuse is not blown, there may be a problem with the wiring or the inverter. In either case, it's best to call a professional to troubleshoot and fix the problem.

If your solar panels have stopped working, there are a few things you can do to troubleshoot the issue. First, make sure that the solar panels are actually turned on. They may be in "OFF" mode if you just installed them or if there was a power outage. To turn them on, look for a switch near the solar panel's inverter or on the wall near the solar panel. If the panels are turned on and they're still not producing energy, it's probably because something is blocking the sunlight from hitting them. Check to see if there is any debris or snow accumulation blocking the panels. If there is, clear it away and wait for sunny weather to resume production.
