How can i power a computer fan via solar power for my science project?
First, pick out a computer fan. They should be marked with the type of voltage they require (such as 120 volts AC, or 12 volts DC), and the maximum amount of current they can draw at full speed (like 100 milliAmps). A fan running with less current, will still run, but will simply spin more slowly. Try to find a fan that runs on DC voltage and current, as this should simplify your design. Many fans require AC. Small solar cells typically produce DC voltage and current, which is why your design will be easier if you find a small fan that runs on DC. You may have to connect several solar cells in series to generate enough voltage (for example, if your fan needs 12 volts DC, and your solar cells put out only 6 volts DC, you would have to connect two of them end to end to make a total of 12 volts). You may have to connect several of the solar cells in parallel to generate enough current to make the fan move. It all depends on what voltage and current the fan requires, and how much oomph you
