Hi,

I realize the Day4 panels give a total of 1.88 kW but is there construction of 9 individual areas likely to give a better overall wattage when there's some shading or cloudiness over the Sharp. I can't find any info on the construction of the Sharp in that regard but here are two docs comparing both the Day4 and the Sharp with similar output ratings:

Day4 60MC

Sharp F1

    The two panels seem pretty similar... The Sharp have a 50 lb per sqft snow loading vs 30 psf rating for the Day4 panels--if that matters in your region.

    Day4 panels appear to be sorted to meet various wattage outputs (around +/- 2%)... The Sharp have a wider tolerance range of +10/-5%... I would not pay extra for the sorting.

    Have not heard about any problems with Sharp... Don't know anything about Day4.
