A 230m² photovoltaic array has a measured output of 37.6 kW. What is the power per area of this array in W/m² to the nearest 0.1?

Which specifications are commonly reported on a PV module specification sheet?

A 1.5 m² module has an STC power rating of 240 W. Calculate the efficiency of the module as a percentage (don't include the percent sign in your answer though, just the number).

You use an insolation map and find that a location has an average daily insolation value of 4 kWh/m²/day, how much usable energy would a 10 kW solar array produce annually at this location if the overall system efficiency of the system were 85%?  

You use an insolation map and find that a location has an average daily insolation value of 5 kWh/m²/day, how much energy would a 8 kW solar array produce annually at this location (before any additional losses from system inefficiency)?

A home consumes 8000 kWh of electricity annually and the home owner wants to install a solar array that can offset 100% of their annual load, how much energy does the solar array need to produce each year if the whole system is assumed to have an efficiency of 80%?

If an area receives an irradiance of 3.5 kWh/m²/day on average, how many hours of full sun does it receive annually?

Using the insolation map from question 7 and assuming an 85% system efficiency, how much energy (in kWh) would be produced annually at a home in Marseille with a 4 kW solar array?

A photovoltaic with a nameplate rating of 20% efficiency delivers a true efficiency of

As a panel heats up, its efficiency
