Solar panels are rated by their theoretical maximum output capacity. A 2-kW PV panel would theoretically produce 2 kW of electricity at its maximum output (during peak solar radiance). If the average daily peak sun-hour in Philadelphia are approximately 4.0 hour and a rowhome is outfitted with 10 PV panels each having a capacity of 260 W, how much energy (kilowatt x hours) would be generated in one year (in units of kWh / year)?

Answer:

3796 KWh per year.

Explanation:

Since, we have considered theoretical maximum output during peak solar radiance which is 4 hours every day.

So, 10 PV panels each of 260 W capacity will produce

260×10= 2600 W of electricity at its maximum output.

2600 W @ 4 hours

Energy in KWh = [tex]\frac{2600\times4}{1000}[/tex]= 10.4 KWh

Therefore, everyday we get 10.4 KWh of electricity at 4 hours peak solar radiance.

So, energy generated for 1 year= 10.4×365= 3796 KWh

The energy produced per year is 3796 KWh.

The given peak solar radiance is 4 hours every day.

So, 10 PV panels each of 260 W capacity will produce an output power of:

260×10= 2600 W

The energy produced in a day will be:

E = 2600×4 Wh = 10.4 KWh

Therefore, energy generated for 1 year is given by:

E' = 10.4×365 KWh = 3796 KWh
