#1.) A solar photovoltaic panel has an area of 3 m^2. The panel's maximum power output is 595 W @ 1100 W/m^2.

a) What is its efficiency?

b) If the panel receives 1300 W/m^2 of irradiance, what is its new power output?

#2.) A solar voltaic module has a maximum output of 200 W @ 1100 W/m^2 when connected to a 2 ohm resistor. What is the maximum voltage and current?

1. 3300 Watts if 100% efficient
595/3300 = .18 so 18%

13/11 * 595 = 703 Watts

2.
200 = V i = i^2 R

i^2 =200/2 =100
i = 10 amps
so
V = i R = 10*2 = 20 volts
