Michael from Little Silver, NJ has been a Green Sun Energy Services client since June of 2025, and booked the charger and the array within days of each other.
A ChargePoint outside the garage
18 July 2025. Hardwired, J1772, on a dedicated 60-amp circuit at 11.5 kW – roughly 36 miles of range an hour – mounted outdoors, to the left of the garage and set back a couple of feet. The load calculation put the minimum service at 132 amps against a 150-amp supply: eighteen amps of margin on a 1,634 square foot house with a sump pump, a refrigerator, a dishwasher and the laundry. That is enough, and it is precisely the sort of figure that has to be worked out rather than assumed – the same house on the same service with a slightly different appliance list could easily have come back the other way.
15 panels and 6.38 kW
Three weeks later, on 7 August: 15 Jinko 425-watt modules with Enphase IQ8PLUS microinverters, rail-mounted, split 5.10 and 1.28 kW across two roof faces – the second of them just three panels – and estimated at 5,251 kilowatt hours in the first year. Microinverters are what make a three-panel face worth having at all: each panel converts on its own, so a small awkward plane contributes whatever it can rather than holding back the string it would otherwise share. The roof needed nothing, and JCP&L interconnected the system in September.
A modest array and a large charger
The charger can pull 11.5 kW and the array is rated at 6.38, and the two are not meant to match. An array is sized against a year of consumption and the usable area of a roof; a charger is sized against how quickly somebody wants to be able to leave in the morning. What buying them together actually buys is not balance but information. The array was designed for a household whose consumption already included a car, and the charger went onto a service whose remaining headroom had already been measured. On 150 amps and fifteen panels’ worth of roof, both of those were numbers worth having before either job started rather than after.

Questions from Little Silver homeowners
EV chargingCan a ChargePoint charger charge a Tesla?
Yes. ChargePoint offers Home Flex with either a J1772 or a NACS connector. The NACS version connects directly to compatible Tesla vehicles, and the J1772 version charges a Tesla through the adapter Tesla supplies.
SolarCan the utility require upgrades before approving a system?
Yes. Some interconnections require utility-system modifications -- transformer capacity, voltage, protection equipment, secondary conductors, service equipment or other distribution work. Who bears the cost depends on the applicable interconnection rules and the utility's determination.
EV chargingCan I install an EV charger myself in Little Silver, NJ?
Homeowners may have limited rights to perform electrical work on property they own, but permitting, code compliance, inspection, and safety requirements still apply. Because EV charging is a continuous high-load application, professional installation by a qualified electrical contractor is strongly recommended.
