high density solar panel surface, output power is around 300 to 430 mW, panels are in series (not much deal for the size), surface looks pretty nice out of the box, size is tiny. No power marks, no protection diodes, or circuitry, epoxy layer can get some scratch marks rather quickly Great small size for most hobby projects, definitely recommended for ... Read more
Very good prizing, the polarity of the cell is marked so it's ok (you'll need a welder 30 watts it's ok, even too much) its ok for doing small toys, power for clocks, and small experiments it have not wires.
it's not acuracy, mine is 102x41mm and the transparent protector its not well atached on corners The real voltaje it's hard to measure, it changes ... Read more
Contains multi-crystalline silicon cells with a good density ( some solar panel manufacturers put less cells and leave large black spaces between them, so this products is ok) Has high enough voltage for most applications of 5.5-5.8V under strong sun. Even on cloudy days it will give 4V. After measuring the solar cell surface I calculated the max power ... Read more
