Answer 1

Explanation:

The efficiency of solar cell is 10 percent and it has maximum current of 500 mA, maximum voltage of0.5 V and F.F.of 0.7. Calculate input power

Answer 2

Answer:

The input power, $P_{in}$, calculated is $1.75W$.

Explanation:

Data given,

The efficiency of the solar cell, η = $10\%$ = $\frac{10}{100}$ = $0.1$

The maximum current in solar cell, I = $500mA$ = $0.5A$

The maximum voltage of the solar cell, V = $0.5V$

The fill factor, F.F = $0.7$

The input power, $P_{in}$ =?

From the formula given below, we can find out the input power:

• $\eta = \frac{V\times I \times F.F}{P_{in} }$

Therefore,

• $P_{in} = \frac{V\times I \times F.F}{\eta }$
• $P_{in} = \frac{0.5\times 0.5 \times 0.7}{0.1 }$
• $P_{in}$ = $1.75W$

Hence, the input power, $P_{in}$ = $1.75W$.
