Sun Solar Panel Info

[READY2GO]

Does anyone have any experience with solar panels from Sun Electronics? I am thinking of buying one of these. SUN-DA121 [SUN-DA121-C1] - $143.99 : Solar Panels, Inverters and Renewable Energy, Powered by Nature! They are cheap, but large and heavy. Mayby it is old technology. 121 watts for $144.00 I might be able to live with the size. If I mounted it right, it could double a a bimini LOL.

These are high voltage panels. You are going to need a high voltage mppt controller that can handle the 140V open circuit voltage qnd the 121 volt maximum power point voltage. Most common charge controllers can't handle this voltage. These are meant for large rooftop arrays supplying 120 Volt house voltage. The advantages are that you can get away with fairly light wiring if you can find an MPPT charge controller that can step the 120V down to 12 and increase the amperage above .9.
