Unformatted text preview: which allows light to pass while it protects the semiconductor wafers from weather elements such as rain , hail , etc. Solar cell modules are usually connected in series which creates more voltage . If the solar cell modules were connected in parallel they would just yield a higher current. Modules are either interconnected in series, parallel, or both, to create an array with the desired voltage and current. In the cell, the light pumps electrons out one side of the cell, through the circuit, and back to the other side, energizing any electrical devices found along the way.The power output of a solar array is measured in watts or kilowatts .
