Area Required For Solar Panels

The typical homeowner will need 28 34 solar panels to cover 100 of their energy usage dependent on location and roof size.

Area required for solar panels.

Total area 1 0 18 5 56 m 2. 17 42 panels to generate 11 000 kwh year. You might have heard that solar power plants require significant amounts of land to generate power. I you are going to install all the panels in one line you would need a space of approximately 1 m x 5 56 m each panel having a size of 1 m x 0 556 m on your rooftop.

The saharandesert is 9 064 958 square kilometers or 18 times the total required area to fuel the world. By another measure the unpopulated area of the sahara desert is over 9 million km which if covered with solar panels would provide 630 terawatts total power. Thus a 1 mw solar power plant with crystalline panels about 18 efficiency will require about 4 acres while the same plant with thin film technology 12 efficiency will require about 6 acres. Rooftop plants weigh 30 60 kgs m 2 66 130 lb m2 which is too heavy for asbestos roofed sheds.

1 kw of solar panels require approximately 100 sqft or 10 sqm when used on rooftops and in small ground mounted installations. Rooftop solar pv plants require about 100 sq ft 10 sqm of shade free roof area per kw of plant capacity. To get these numbers we used high and low panel production ratios to calculate how many solar panels are needed on average. You have a rough estimate of the space required by the solar panels of your system.

The area required by thin film panels is about 50 more than that for the crystalline as the latter are about 50 more efficient than the former. Use a low wattage 150w and high wattage 370w example to establish a range ex. From these two one can now make a reasonable estimate of the area needed. For example for a 1 mw solar power plant installation the solar farm land requirements would be around 4 acres when using a crystalline technology.

However you can use the same procedure to estimate how many are needed. Solar shingles are smaller than panels and their wattage is lower as a result. For example if the amount of power needed is 5 000 watts and each shingle is rated at 50w you need 100. When we use thin film technology a 1mw plant will require an average of 4 5 to 5 acres of land.
