Okay I'm appealing to the knowledgeable folks here at CF again. This time, the ones with knowledge of
solar power.
I know there has been extensive coverage of the
solar topic on here but I seem to have a unique situation here.
I was looking at the
Rutland 914i
wind generator and the 160W controller which accepts power from
wind and up to 160W of solar. I decided to by the
wind genny and pass on the controller because I wanted to be able to connect more than 160W of solar.
Shortly after making that decision, a friend of mine gave me 550W of
solar panels, 11 of them

BUT now I'm having difficulty finding a controller that will
work with wind and solar AND that will
work with these
panels.
The trouble is that I'm not sure what voltage they are.
Here are the specs.
Pmax = 50W
Voc = 32.56
Vmp = 27.60
Imp = 1.81
Isc = 1.99
Production Tolerance +/- 3%
VDC = 1000
It looks to me like they are 24V but someone told me they're 18V.
I would really appreciate some meaningful feedback on this. I have tried seeking the
advice of professionals in the industry and surprisingly, I have gotten conflicting answers from all of them and even one guy who flatly refused to comment on
panels that he didn't sell me, even though he have
sold me a controller to match them. Some people!
Edit: I should clarify that I don't intend to use all of the panels but would like to find a good balance between space/weight vs output.
