How Do You Make A Solar Panel That Works?
There are now a variety of reasonably priced individual solar cells available on the market, opening the way to the do-it-yourself assembly of solar panels that are designed to fit specific needs. This means anyone can have a solar panel that really works, avoiding any problems with the panel not producing enough juice to meet its dedicated power requirements. Determine the combined electrical demand of all devices that will be powered by the panel. For example, if the panel is to power a 10-watt ventilation fan that will run 24 hours a day, it will consume 240 watts. Determine the necessary power output of the panel to meet that demand. An average day is supposed to have 6 hours of peak sunlight, and most solar electric computations are based on that. So, the entire 240 watt output must be met during those 6 hours, which means the panel must produce 40 watts per hour. Choose the specific solar cell that you want to use, and then sketch a plan. In this example, 10 watt cells that are 1
