It takes about 120 square meters per windmill knowing that now i believe we should stop windmills and start using solar panels.
How much space does one solar panel take up.
So if you want to get a sense of how many panels a roof can support multiply the square footage of the roof by 75.
The average solar panel is about 3 x5 which adds up to an area of 15 square feet total.
However a 4kw sunpower system right takes up much less space delivering the same amount of clean electricity.
Generally the setback will take up 25 percent of the usable space on the roof.
A simple rule of thumb is to take 100 sqft for every 1kw of solar panels.
A single panel can have a foot print of about 4 long and 30 wide so an array of 8 panels can be approx.
24 long depending on how they are oriented.
Yes windmills take up to much land.
Extrapolating this a 1 mw solar pv power plant should require about 100000 sqft about 2 5 acres or 1 hectare.
Take that number and divide it by 17 5 which is the average square footage of one solar panel.
This setback varies from state to state.
Because sunpower panels produce more power per square foot you ll get more power density in a smaller area.
However owing to the fact that large ground mounted solar pv farms require space for other accessories the total land required for a 1 mw of solar pv power plant will be about 4 acres.
