The ALLPOWERS SP039 is a 600W folding solar panel for large solar generators and RV setups. It uses monocrystalline cells rated at up to 23% efficiency and puts out about 44V through MC-4 ports, so it pairs with big stations like the S2000 Pro and R4000. It folds into six panels and weighs 27.5 lbs, lighter than many 400W panels, which makes it easier to carry and mount. Buyers rate it highly, though a 600W rating is a peak figure, so real output depends on sun angle and conditions.

With 4.8 out of 5 from 77 ratings, owners are largely satisfied. They praise the build, the folding design and the charging speed for large power stations. The main caveats are weight and output that depends heavily on conditions.
The ALLPOWERS SP039 is a 600W foldable solar panel with MC-4 output ports and 44V output. It is made for large solar generators, including the ALLPOWERS S2000, S2000 Pro and R4000, and can be fixed on top of an RV.
It has 6 foldable panels and folds down to 23.6 x 35.7 x 1.9 inches. It weighs 27.5 lbs. The panel uses monocrystalline solar cells that convert up to 23% of sunlight into electricity, and it can still collect solar power on a cloudy day.
The panel is built from multiple layers of flexible EVA and glass fibers, with a coating that holds up in frozen or hot weather. Its IP67 rating protects it from scratches, dust, water splashes and short periods of soaking.
