You have a rough estimate of the space required by the solar panels of your system.
Area required for solar panels.
On the other hand if they are 330w panels only 21 are needed.
In other terms we can say that for each 1 kw of solar panels you need 100 sqft of an area on average.
You can calculate how many solar panels you need by multiplying your household s hourly energy requirement by the peak sunlight hours for your area and dividing that by a panel s wattage.
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.
The average solar panel is about 3 x5 which adds up to an area of 15 square feet total.
Rooftop solar pv plants require about 100 sq ft 10 sqm of shade free roof area per kw of plant capacity.
17 42 panels to generate 11 000 kwh year.
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.
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.
1 kw of solar panels require approximately 100 sqft or 10 sqm when used on rooftops and in small ground mounted installations.
However you can use the same procedure to estimate how many are needed.
Use a low wattage 150w and high wattage 370w example to establish a range ex.
Total area 1 0 18 5 56 m 2.
You might have heard that solar power plants require significant amounts of land to generate power.
When we use thin film technology a 1mw plant will require an average of 4 5 to 5 acres of land.
Area required for solar pv power plants.
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.
However this is a rough estimate as space can also be influenced by the efficiency of the panels and technology.
Shadows falling on the panels not only reduce power output but also damage the panel.
Solar shingles are smaller than panels and their wattage is lower as a result.
