I ordered 2*40 feeds solar panels 1270 PCs and they arrived in good condition. Once tested I was happy with the output that was higher than another brand panel that I bought another solar module factory in China.
I am in a northern state of America and the sun is always less than directly overhead. These panels when connected 2 in series to a inverter are outputting near their rating for about 3+ hours per day and are above 60% of their rated output for more than 6 hours per day.
Because I was happy with the first order, now Sunpal is the only solar panel supplier,  I will be ordering additional panels from them.
