77 square kilometres of land From the picture 75% of it is occupied by solar cells. 54 square kilometres of solar panels that need cleaning maybe once a month. So 1.8 square kilometre for solar panels cleaning per day. That's a square 1.34 km on each side. The panels look 2m by 1m. So that's 670 x 1340 panels = 897,800 panels that need cleaning every day. At least India has enough cheap labour atm. to just throw people at it.
