Area covered by the wiper is that of a semi-circle with diameter D, or the length of the solar panel - 156 cm.
So the area = (1/2)*(PI/4)*(D2) = (1/2)*(PI/4)*(156cm2) = 9556.72 cm2
Now find the area of the solar panel: area = length*width = 156 cm * 78 cm = 12,168 cm2
Now % area cleaned will be the area of the wiper / area of the panel:
9556.72 cm2 / 12168 cm2 * 100% = 78.5%
