Frank from Williamstown, NJ has been a Green Sun Energy Services client since October of 2017. He and Monika signed at the end of October and the array was producing by the twenty-ninth of December, 50 Canadian Solar 300 watt panels on Enphase IQ6 microinverters. At 15 kW it is the largest residential array in our records, designed for about 19,402 kWh a year, which is more than double what an average household draws. Williamstown is in Gloucester County.

Solar questions from Williamstown homeowners
How is the number of panels for a Williamstown house decided?
It starts with the home's actual electricity use, then with how much usable roof or ground area there is. A proper design looks at twelve months of consumption, expected future use, roof orientation, shading, roof dimensions, code-required setbacks, module wattage and the limits the utility places on interconnection.
What does a 460-watt panel mean?
It is rated to produce up to about 460 watts under standardised laboratory conditions. Twenty-five of them make 11.5 kW DC; twenty-six make 11.96 kW. The panel count and the wattage should multiply out to the DC system size stated in the proposal -- if they do not, something has been rounded that should not have been.
Are panels designed for the wind near Williamstown?
Yes. The array and its mounting system have to be designed to resist the applicable wind loads, and coastal and exposed locations can carry different wind-design conditions from sheltered inland ones. It is one of the reasons the mounting system and its engineering are chosen for the site rather than by habit.
