Asolar panel measures 80 cm by 50 cm. in direct sunlight, the panel delivers 4.8 a at 15 v. if the intensity of sunlight is 1 000 w/m2, what is the efficiency of the solar panel in converting solar energy into electrical energy?

The solar panel efficiency in converting solar energy in electrical energy is 18%.

Explanation:

The solar panel's  efficiency can be defined as:

Where Pe and Ps are the output electrical power and input solar power respectively. The electrical is computing in terms of the voltage and current delivered:

The net solar power of panel is found by multiplying the solar intensity by the panel area in square meters:

Finally the panel efficience n is:
