More Solar for "Us"
Ok, I went off.the deep end? Bought 3 used 37watt uni-solar panels and a blue sky 2000e controller for the hefty price of $400, They were being listed as 75w panels, they are not The tested open...

Hi,
Unisolar have:
A. no glass, so no reflection off that surface (and also no glass to break)
B. diodes between each cell in the panel
C. a triple layer of electricity producing material, each "tuned" to a different frequency of light.
D. Are about twice to three times the size of a similar wattage mono or poly panel.
Their final product was a flexible panel with an adhesive for fastening directly to a roof. They gambled big time on a flexible solar shingle and lost that bet.
The ones Mr. Wizard and I have the active material directly depositing on the panel as a thin film. The lack of glass means that heat tends to not build up in the panel and that any breeze may cool them faster than a traditional panel. The output voltage is 16.5. I chose to go series/parallel with mine requiring an MPPT controller. Mr. Wizard did not. I can't remember if his system is MPPT or not.
If I were not full time, I would not dream of changing from what I have, but as it now stands, I simply don't have as much wattage as I could wish for.
