Surface Area Of Solar Panel

To figure out what the total surface area is simply multiply the length and width of the solar panel by each other.

Surface area of solar panel.

The number of solar cells on one panel is directly related to its length. Solar panels need to have a lot of surface area that can be pointed towards the sun as the spacecraft moves. Each individual panel usually has an area of 1 3 1 7m2 with 1 6m the most common size. The number of solar panels of the size used in the calculation will theoretically meet that energy demand during a sunny day.

Another way is to multiply the household s hourly energy requirement by the peak sunlight hours for the area. If an average solar panel measures at 65 inches by 39 inches how does that translate to a full sized rooftop solar panel system. Lets assume the solar panels have 20 efficiency so the energy produced is 200 watt m 2. Since spacecraft have to be small this limits the amount of power that can be produced.

To calculate the area you need to know the efficiency of the solar panels. Sunpower panels are 61 3 inches by 41 2 inches. Solar panels are installed in arrays with the number of panels varying depending on the roof area available and the amount of power you wish to generate. More exposed surface area means more electricity can be converted from light energy from the sun.

72 cell commercial solar panels are approximately 13 inches longer than 60 cell residential panels. A total surface area this is the total surface area of your solar panels.
