May 2, 2013 Kathie Zipp : A solar panel, or module, is a series of interconnected silicon cells joined together to form a circuit. In greater numbers the amount of power produced by these interconnected cells can be increased and used as an electricity production system. Solar panels come in different sizes for different purposes. The current standard offering in the market is a 60-cell panel, with larger 72-cell panels being used for larger-scale installations.
