The average annual solar flux in New York is 250 W/m2. Suppose 10 m2 of solar electric panels operating at 10% efficiency were installed on a home there. A) How many kWh of electricity could be collected by these panels in one year?

B) What fraction of the annual electrical requirement of 10,000 kWh for the average home does this represent?

C) How many square meters of solar panels would be required to supply 10,000 kWh per year?

explanation:

the masses of the objects and the distance between them

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
