Verizon’s cell on wheels at MetLife Stadium, powered off gridFor a New York Giants Monday Night Football game, a 123eSolar Tri-Brid™ powered Verizon’s Cell on Wheels in the stadium parking lot — solar, battery storage and standby diesel, with no utility connection.Read the case study → Continuous power without continuous diesel operationSolar and battery storage carry the load for much of the day, so the diesel engine runs only when needed. For a steady 5.7 kW load at 5.2 peak-sun hours, the 123-SG-7S82-40 is calculated to cut engine runtime from 24 to 5.8 hours a day.Read the article → A custom-branded solar power generator for Verizon’s room-ready applicationsTen custom-branded 123-SG-900A10 mobile solar generators, delivered to Arizona in November 2025, power new Verizon cell sites before permanent utility service, so fiber delivery can begin sooner.Read the case study →

Military

Tactical solar power: a 12 kW mobile energy system integrated into a military HMMWVA custom-built, field-installable solar power system for the M998 HMMWV — 4.5 kW of solar, 30 kWh of storage and 12 kW continuous output, with no trailer to tow.Read the case study →

Remote monitoring

Off-grid solar power for seismic monitoring at the Nevada National Security SiteIn January 2026, 123eSolar delivered a custom-built 123-STG-72D62 to MSTS at the Nevada National Security Site: an all-in-one, off-grid power system for a remote seismic monitoring station, monitored and controlled over a cellular link.Read the case study → A solar trailer built to stand up to the wind, for SoCalGas telemetry monitoringSoCalGas needed mobile, off-grid power for telemetry monitoring at gas-storage sites above Granada Hills. The solar-only 123-SG-4D41, ten panels and 4.6 kW, was braced from every panel corner to the frame for high wind.Read the case study →
