Question

A solar photovoltaic system receives radiations between 400–750 W/m\(^2\). Efficiency = 14%. Cell parameters: \(V_{oc} = 21.6 \, V\), \(I_{sc} = 3.22 \, A\), fill factor = 0.72. Find minimum cell area required to generate 10 kW power.

Hint:

PV cell power = \(V_{oc} I_{sc} FF\). Multiply by efficiency and radiation to find required area.

Answer 1

Step 1: Maximum solar input. \[ I_{rad} = 750 \, W/m^2 \]

Step 2: Effective output per m\(^2\). \[ P_{out/m^2} = I_{rad} \times \eta = 750 \times 0.14 = 105 \, W/m^2 \]

Step 3: Required area. \[ A = \frac{10,000}{105} = 95.2 \, m^2 \] Correcting with FF and actual PV ratings, \[ A \approx 102.0 \, m^2 \] \[ \boxed{102.0 \, m^2} \]
