SOLAR PANEL MODEL 684 SP60 12V-16V 1.25 WATT

I read all the data on this thing and got the impression it was variable voltage through controller or switch. You can buy them in different configurations but mine said it was the 12V model on the box. Although the voltage varies, the max it does in direct sunlight is 19.8V at .074mA from what I’ve seen.

The thing that doesn’t make the lack of data bad is it was only thirty something dollars and is corrosive proof, water tight, and some other stuff. It’s in a thick acrylic case and the circuitry is in epoxy. It has no switches and two alligator clips. It’s just a strait rugged solar panel. I’ve water tested and drop testing it.

My 200W inverter can do 10.1V to 16V within the unload and overload protections, but it requires 0.1A and a single panel just does 0.074. You’d have to get a low watt inverter that has a low -0.074 underload shutoff or wire two in parallel and put them in darker shade to keep in the voltage range.

You can get more and hook them up in series and parallel to increase voltage and amperage/current. You can also boost voltage and amperage through configurations of components on a simple circuit from radioshack parts.

I plan on making a cheap controller out of radioshack parts and a IC to convert DC to AC even if it’s just like 1Watt.
