A 400 watt solar panel is usually 78 inches (6.5 feet) by 39 inches (3.25 feet). It weighs about 60-70 pounds. What type of solar cells are used in a 400 watt solar panel? These panels use high-efficiency monocrystalline or polycrystalline silicon solar cells. This helps them produce a lot of power.
A 400-watt solar panel’s efficiency depends on the manufacturing company. However, on average a solar panel is capable of converting 20% of the solar energy that it is receiving. Open circuit voltage is the maximum voltage a solar panel can generate without load on it. The open circuit voltage of a 400-watt solar panel is about 49.3 – 49.95V.
A 400-watt solar panel doesn’t take that much space. Let us define how we calculate 400-watt solar panel space. A solar panel is typically 6.5 x 3.5 in dimensions, which makes about 22.75 square feet of space. 20% of space will be required for wiring, adjusting combiner boxes, and space left between panel springs to prevent shaking.
Rather, we get the typical sizes of solar panels by the number of cells (which is quite useless). There are 3 standardized sizes of solar panels, namely: 60-cell solar panels size. The dimensions of 60-cell solar panels are as follows: 66 inches long, and 39 inches wide. That’s basically a 66×39 solar panel.
The wattage of residential solar panels typically range from 300W to 1KW. A 300W solar panel usually measures 1.6m x 1m and weighs approximately 20kg. A 400W solar panel is usually 1.6m x 1.3m and weighs approximately 22kg. Lastly, a 1KW solar panel measures 1.9m x 1.6m and weighs approximately 34kg.
For calculating the current produced by a 400-watt solar panel we use the following formula The total current produced by the solar panel = total energy produced / voltage of panel For 12V solar panel: 400 watt / 12V = 33.33 Amp For 24V solar panel: 400 watt / 24V = 16.67 Amp For 48V solar panel: 400 watt / 48V = 8.33 Amp
