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?

Explanation:

If the family needs 26 kW of power, and knowing that the efficient is 30% the relation between the solar flux and the power would be:

(1)

e is the efficient (in our case 0.3)

Φsolar is the solar flux

S is the effective surface

Solving (1) for S we have:

I hope it helps!

the electric field is a “force field” around a charged object that illustrates the direction the electric force would push an imaginary
