Solar Made JSS panels are constructed from high quality monocrystalline silicon solar cells and operate at 3 Volts, 1+ Amp to produce slightly greater than 3 Watts.
Each individual solar cell on the panel measures 52x100mm. The six cells per panel are arranged in a series circuit to increase the ~0.5V of each cell to the 3V necessary to meet the JSS Competition Specifications. Average efficiency of these cells is appx. 16-19%
