POTSDAM, NEW YORK · COMMISSIONED 2026

43 kilowatts, two ground mounts, and a National Grid export limit.

This is the largest of the arrays I have built. It powers a fragrance factory and sends its surplus to a grocery store in the next town over. Here is what it actually consists of.

The array

Why the export limit is the interesting number

The array can make 43 kilowatts. The inverters could push 48. National Grid will accept 24. That gap is the whole design problem, and it is the part nobody tells you about when they quote you a system.

Export limiting is enforced in the inverters themselves rather than by a downstream device, and it is not something I can change casually. Once you accept the constraint, the system stops being about peak output and starts being about when the power is produced and where it goes. That is why the racking tilt gets moved by hand every month, and why the surplus is credited somewhere it will actually get used.

Remote net metering

The array sits at the fragrance farm in Potsdam. The credits go to the grocery store in Canton. New York allows remote net metering between accounts under the right conditions, and the paperwork to make it real was more work than the trenching.

Doing it in house

Layout, racking, DC strings, rapid shutdown loop, isolators, emergency stops, inverter commissioning, parallel configuration and firmware, done in house and inspected and signed off before energisation. I am not selling solar installation and I am not looking for solar clients. I built these because I own the buildings and the arithmetic worked.

The rest of it

Earlier arrays across other properties bring the total to roughly 64 kilowatts DC, including a battery-charging array on a separate charge controller. They are smaller, older, and taught me most of what made this one go smoothly.
