This can make it tricky to get a rough estimate of how much it will cost to build per acre of solar panels.
How many solar panels per acre.
A simple rule of thumb is to take 100 sqft for every 1kw of solar panels.
When we use thin film technology a 1mw plant will require an average of 4 5 to 5 acres of land.
However this is a rough estimate as space can also be influenced by the efficiency of the panels and technology.
This means that for a 1mw solar pv power plant the area required is about 2 5 acres or 100 000 square feet.
A good rule of thumb is that on average a one acre field of solar panels will cost from 400 000 to 500 000 before government incentives.
For a typical solar installation the general rule of thumb is that for every 1kw of solar panels needed the area required is approximately 100 square feet.
That depends on the amount of kw of mw you would like to accommodate.
Extrapolating this a 1 mw solar pv power plant should require about 100000 sqft about 2 5 acres or 1 hectare.
By comparison imagine solar power.
On average 1 square meter of solar panels directly exposed to sunlight will receive about 1 kilowatt hour kw h of energy per hour for the six hours it is exposed to effective sunlight or 6 kilowatt hours of solar energy a day.
