JinkoSolar unveils details of its TopCon 620 W bifacial solar panel

I agree it is designed for "recommended for utility-scale projects" where two people can carry each 76.6 lb. panel to a ground based rack. My array is on the 42 degree pitched roof of a 3 story home = up 40+ feet. I expect extremely expensive OSHA rules for panel installation for such a location. Yet dense city locations are just where the high afternoon air conditioning loads put the biggest demand on the distribution grid. Distributed local generation meets that load most efficiently.
