Patent ID: 7786375

Claim:
A solar energy system comprising: a solar cell module array comprising a plurality of backside contact solar cells, the solar cells being coupled in series such that a first node of the series is at a positive potential and a second opposing node of the series is at a negative potential relative to the first node, each solar cell in the plurality of backside contact solar cells having a doped front side diffusion region and a dielectric over the doped front side diffusion region; a frame of a solar cell module in the solar cell module array; an inverter configured to convert direct current generated by the solar cell module array to alternating current to be provided to a power grid; wherein the first node of the series and the frame are grounded to reduce positive potential between the solar cells and the frame; wherein the inverter is configured to receive a balanced voltage from the solar cell module array and further comprising: a resistor coupling the first node of the series to ground, the resistor having a value configured to unbalanace the balanced voltage from the solar cell module array.
