Motorhome Solar Panel Problems

I just bought a 40a mppt controller a top end 200 monocrystalline module cable fuses and sealant for just over 400 dollars.

Motorhome solar panel problems.

Gary bunzer aka the rv doctor re. If you think your panels are having trouble producing optimum power we have some troubleshooting tips that might help out. However like everything else a solar panel system can experience some problems with light production. How do we tell if the solar panel is charging the batteries on our 2002 motorhome.

So that means you were measuring the open circuit voltage voc which i would have expected to be about 20v. Cupping extreme temperatures can make the flexible panels slightly warp causing water dirt dust and sand to buildup in these little cups on the panels. If you can take a voltage reading coming directly from your panel s wires which must be disconnected from the controller the reading should be as high as 29 volts. Move the cables away from the charge controller and use adhesive tape to keep the cables away from anything nearby.

Installation of flexible panels means you will need to glue them to your roof and it is not an easy process to remove them later and can result in damage to your roof or to the panels. Set the dvm to the 10 amps range and change the probes as necessary. All panels that you test will need to be done individually and make sure there is nothing on their surface. Typically a motorhome solar panel creates 17 18v of charge.

In order to troubleshoot your panels you will need a multimeter panel specification sheet and sunlight of course. There is an option. Cover the solar panel and remove the battery fuses. Deb from gilbert ariz wants to know.

Do a shading test solar panels require full exposure to light to produce a robust light in the home. If your solar panel system is not producing properly you can troubleshoot it to determine the cause of the problem. I ll give you an example. When sunlight strikes the panel photons are absorbed which causes electrons to separate from the silicon atoms and move about.

Flat roofs our rv has a pretty flat roof so when we park and level our coach the panels are basically flat. While in winter months this can be a great thing as far as the hot summer months not so much. This creates a dc electric current which is collected and directed via a controller to charge your leisure battery. If i understand you correctly you measured the voltage across the solar panel output wires whilst they were disconnected from the solar regulator and had a reading of 10 1v.

The controller is the component that regulates the volgtage from the solar panel to the batteries.
