2 acres is ~8000 square meters, which is around 90m2.
Of course, this depends on the insolation of the site - how much sun falls on the PV panels - and the efficiency of the panels, which for commercial panels is around 20% as of early 2013.
Higher latitudes - closer to the poles - have lower insolation; within temperate regions (20-40º from equator), the range is 3.0-6.6 kWh/day/m2, with winter varying to 50-65% of summer in these ranges.
I've not yet been able to determine the relationship between insolation and the area required for 1MW of output from PV.
They have solar panels to produce electricity.
Solar panels are cheaper because your consistently producing your own electricity by using solar panels. If you produce more electricity then the electric company will pay you.
There are two main types of solar energy. Solar Thermal - Used for heating water Solar Photovoltaic (PV) - Used for producing electricity Solar Thermal is very prevalent in the Leisure industries where a steady stream of hot water is required for showers etc. Solar Photovoltaic systems are used on homes as they can produce enough electricity to power most household appliances, during daylight hours. There are also solar torches and solar lights. These work by storing the electricity during the day where you are then able to use it at night.
Solar panels must be constantly exposed to light to produce electricity
because when there in space they could use the suns energy to produce electricity for there space shuttle.
The solar panels produce electricity by the sunlight.
Solar energy can be used to produce electricity.
Probably because a solar panel can produce electricity for many years.
the solar power plant generates electricity
Solar electricity is the most inexpensive form of electricity. Once the solar panels are installed, the solar power is free. There is also wind energy to produce a low cost electric source.
Capture the sun
They have solar panels to produce electricity.
They all produce static electricity.
the solar power plant generates electricity
Solar energy is radiation that comes from the sun. It can generate electricity and produce heat. They convert solar radiation into electricity.
by using electrons to solar energy
No plant organelle produces solar energy. Only the sun produces solar energy.
