That is the Question, ..... I just purchased "HQST 100 Watts 12 Volts Polycrystalline Solar Panel " They look nice but should I put protective cover, i.e. plexiglass over them? or will that reduce their output?

This is going to be a camping setup, 2 panels, MPPT , 2 4DLT batteries, 750/1500 watt inverter/ 5.0 cu.in. Freezer converted to refrigerator. In years past, I would have to drive into town every 3 to 4 days for ice. Since I camp in the So Cal Desert, I have abundant sun, I am hoping this will run 24/7. But looking at the panels I worry about blowing sand.


p.s. it was either buy another $500+ cooler or this

Assuming they are normal panels covered by glass, I don't think adding plexiglass will improve things. Glass is the hardest affordable material that is still transparent enough and any additional layer will remove light.
I don't know how long normal glass lasts when blasted with sand.. but I assume the windows of the camper are more of a problem for that…

If you run the freezer at full power during the day, the batteries are probably not even needed.
