The Energy Express is a self-contained mobile microgrid built by Solar Alternatives: a wrapped 16-foot trailer carrying two Tesla Powerwalls, a rooftop solar array, and a deployable ground array that sets up on any open field or lot.
Power Without the GeneratorIt runs silently and produces no exhaust, which means it can sit right next to a stage, a tent, a food line, or a crowd — places a diesel generator simply cannot go. There are no fuel deliveries to schedule, no fuel-storage permits to pull, and no noise complaints to field. Roll it in, plug in, and you have clean power for the day.
A working sustainability story your guests can see rather than read about — the Energy Express is a branded, photogenic centerpiece that also does real work:
The Energy Express grew out of Louisiana’s storm-recovery work, and it still does that work. We offer it to qualifying nonprofits and community organizations at a discounted rate, and donate it in-kind for causes we support. Common uses include:
Sized for the loads most events actually need — lighting, sound, laptops, point-of-sale, phone charging, and small appliances.
| Battery storage | 2 × Tesla Powerwall — 27 kWh total usable capacity |
| Solar | 1.8 kW array — recharges the batteries or powers loads directly during the day |
| Power outlets | 8 quad receptacles (32 standard 120V outlets) |
| Trailer | 8.5′ × 16′ enclosed cargo trailer, dual-axle, fully wrapped |
| Setup time | Under one hour with a two-person crew |
| Emissions & noise | None — no engine, no exhaust, no fuel |
