The image attached is a neat copy of a photo of an electricity meter for a domestic solar array. The display shows the energy we sold to the electricity company on a winter's day. Each box is 100 W high and 1 hr wide. At the radius of the earth's orbit, the intensity of sunlight is I=1.4 kW.m–2 . (This means that 1.4 kW.m–2 passes through 1 square metre at right angles to the sun's rays.) The solar array in the previous question consists of 10 panels, each with area A=1.6 m2 . Under optimal conditions - with the sun at right angles to the array and no clouds in the sky - the array produces Pout=2.3 kW . What is the efficiency of the array? Power out/power in = _____ %.
