Walter and Barbara from Bayville, NJ have been Green Sun Energy Services clients since September of 2019. Twenty-nine LG 335-watt panels went on the roof that December – 9.715 kW in all, estimated at 12,710 kWh in the first year – on a Unirac rail-free mounting system, with 152 linear feet of critter guard closed around the edge of the array. Rail-free keeps the panels low to the roof plane, and the guard shuts the gap underneath before anything decides to nest in it.

Solar questions from Bayville homeowners
Are panels designed for the wind near Bayville?
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.
How does an optimizer system differ from microinverters?
An optimizer system puts DC power optimizers at the modules and a single central inverter elsewhere; a microinverter system puts a small inverter at each module. Both can provide module-level monitoring and rapid shutdown when properly designed -- they are different architectures rather than one being the upgrade of the other.
What happens to production in winter?
Panels keep producing, but shorter days normally mean lower monthly output than spring and summer. Cold modules actually operate efficiently; what reduces winter production is day length, sun angle, cloud, snow cover and shading. A properly designed system models production across the whole year rather than a good month.
