How much land do solar panels take up.

Consumes about 4 petawatt hours of electricity per year we d need about 13 600 000 acres or 21 250 square miles of solar panels to meet the total electricity requirements of the united states for a year. In a study by the massachusetts institute of technology mit future of solar energy the authors estimated how much land it would take to power 100 of the us entirely with big solar projects. In other terms we can say that for each 1 kw of solar panels you need 100 sqft of an area on average. That s if we spread solar panels evenly across the entire country.

How much land would it take to power the usa with solar energy. One can then make estimations for a traditional setup. The yellow square is approximately 21 000 square miles. There s 1 8 billion acres of land in the usa so about 0 6 of our land is all it would take.

Amount of land available 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. At 2 8 acres per gwh then about 11 200 000 acres of land would give us what we need to produce the 4 000 000 gwh of solar power. To supply 100 of the entire nation s electricity needs in 2050 with solar it would take 12 741 square miles. A large fixed tilt photovoltaic pv plant that generates 1 gigawatt hour per year requires on average 2 8 acres for the solar panels.

A simple rule of thumb is to take 100 sqft for every 1kw of solar panels. Map courtesy of google maps. 2 8 acres per 1gwh. When we use thin film technology a 1mw plant will require an average of 4 5 to 5 acres of land.

Firstly the solar panels and secondly its structure components. The land required for a 1 mw power plant setup is around 4 acres for crystalline technology and around 4 5 5 acres for thin film technology. Extrapolating this a 1 mw solar pv power plant should require about 100000 sqft about 2 5 acres or 1 hectare. Electricity demand in 2050 with solar energy would require roughly 33 000 square kilometers sq km of land.

This means that a solar power plant that provides all of the electricity for 1 000 homes would require 32 acres of land. That means for a 10 mw power plant 45 50 acres of land would be required.
