A PV battery system has an efficiency of 80%. The system is used to run an all-AC load that is run only at night. The charge controller efficiency is 96% and the inverter efficiency is 85%. How much energy will need to be generated by the PV array if the load is 150 watts running for 5 hours per night?
The annual average insolation for a fixed solar panel in
city A is 350 W/m2. On the other hand, city B has a figure
of 300 W/m?. For both locations, the solar panel has the
capability to convert 17% of the incident energy into
electricity. Average annual electricity in City A is 13 000
kWh with an average cost of $0.4/kWh, while in city B, it
is 10 000 kWh at a cost of $0.75/kWh.
For City A,
a. Determine the area of the solar panel needed in order
to suffice the average electrical needs of a residence.
b. Determine the area of the solar panel needed in order
to suffice the average electrical needs of a residence in
City B.
c. Determine the price per square meter of solar panel in
City A if the device has a lifetime of 20 years. Assume
that the electricity costs are constant throughout the
period.
d. Determine the price per square meter of solar panel in
City B if the device has a lifetime of 20 years. Assume
that the electricity costs are constant throughout the
period.
