At the surface of the earth, there is an approximate average solar flux of 0.75 kw/m2. a family wishes to construct a solar energy conversion system to power their home. if the conversion system is 30% efficient and the family needs a maximum of 26 kw, what effective surface area is needed for perfectly absorbing collectors?
