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)?

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 = = 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
