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...

OK, i was looking at one of the solar calculators site,
this So Calif region, gets like 0.302kw per meter in Jan
and 0.739 kw per meter in may-june-july
panels are rated and tested at 1kw per sq meter
so to get panel rating the solar energy level has to reach 1kw per sq meter
at 739w per sq meter, 0.739kw my peak sustained output should be 73.9% of the rated 321w, whic is 237.22 watts which at 13.8v that is 17.19 amps
at 14.6v that is 16.24 amps
I am not too far from those numbers
I am never going to see 321 watts unless it is while in a different location
5.5 is a yearly avg of hrs of peak power for this area
the numbers vary by area and are used to determine how much power KWH can be developed by a signal 100w panel per year at any given location, used to figure out how many panels are needed to produce a given amount of KWH yearly
if you only camp in the summer in a given area, you can use the peak numbers to see the theoretical max you can achieve with different wattage panels
so the max my panels can produce for my current area is in the neighborhood of 7*237=1660.53whrs for summer and 700+whrs for max winter
ive seen the winter max, i have not yet achieved the summer max
