When the sun shines, you get power! No muss. No fuss. It's absolutely silent, and it's pretty much maintenance-free. All I (Libbie) do aboard s/v HOTWIRE is use a damp sponge or rag once in a while to wipe off dust, salt, and bird poop! Where we are now, I clean ours a couple of times a year. When we were downwind from the cement plant at Puerto la Cruz, Venezuela, I cleaned them much more often. The cleaner the surface, the better it works for you.
The solar cell is one small (approx. 4"x4") area on the surface of a solar module. The module is made up of many solar cells set into a frame for support. A solar panel is several solar modules installed together on a rack. Put some racks together and you have a solar array.
Yes, put 2 AAA rechargeable batteries into and SolarUno can store its energy.
The power can be 5V USB output 150mA.
Fully charging 2 AAA rechargeable batteries with SolarUno by the sun takes typically 4 hours of sunlight; 1 AAA Ni-MH battery takes typically 2 hours
Yes, you can charge SolarUno even in cloudy & ambient light conditions, although significantly less power is produced.
With the high flexibility, SF Solar Panel can be bent without breaking, but do not fold it.
SolarUno can charge most of MP3 players, including iPod series.
Depending, place 1 or 2 AAA batteries in battery holder before charging MP3.
Gently wipe a slightly damp cloth over SolarUno. Never use abrasive, corrosive solvents or chemicals.
You can put 2 AAA non-rechargeable batteries in and use SolarUno as the "inverter" to charge your USB-powered MP3 player.
Although leaving SolarUno in the car while charging is harmless for SolarUno, but the heat may cause damage to your devices. Therefore, we do not suggest you leave SolarUno and your devices alone in the car while charging.
