ALLPOWERS SP039 600W review
ALLPOWERS SP039 600W Foldable Solar Panel
By Tom Calder
600 W in one folding panel, so a big station refills in far fewer hours than with a 200 W panel. ALLPOWERS rates it IP67 and about 23% efficient. At 27.5 lb and almost 7 by 6 feet unfolded it needs space and a strong arm, and its 52.8 V open-circuit voltage is too high for small stations, so check your station's solar input limit first.
