Getting real solar power onto an acreage without permanently fixing panels to the ground is a tricky problem. This build tackles it by making a transportable ground array that can feed an EcoFlow Delta Pro, with the stated goal of keeping an EV charged down the highway and powering a four wheeler around the property. The whole thing rolls, so it can be repositioned rather than living in one spot.
The foundation is an old hay rack running gear, and the maker built the frame from thick salvaged wooden utility beams with pressure-treated 2x4 crossbars. It sits on a red-painted wheeled chassis with four pneumatic rubber tires, and the panels mount on aluminum rails held up by metal struts. The main array is fifteen Eco-Worthy 100-watt monocrystalline bifacial panels set out three rows high and five columns wide. There is also a smaller wheeled wooden cart carrying four non-bifacial 100-watt panels as a companion.
The wiring is a 5-series, 3-parallel configuration using 3-to-1 MC4 branch connectors. One clever workaround stands out: the standard 45-inch adjustable tilt brackets only accommodate two vertical panels, so the maker bolted together one and a half brackets per column to carry all three tiers. The gaps between panels serve wind release and give the bifacial cells something reflective below. On the monitoring side, the EcoFlow app showed solar input between 1.06 kW and 1.08 kW, with the battery at 33 to 35 percent, 79°F, and roughly three hours left until full charge.
The one open item is structural. Moving a rig this size flexes the frame, and the maker plans to add diagonal reinforcement bars to reduce that flex. Bolting half brackets together to stretch a two-panel mount into a three-panel one seems like a smart, thrifty fix to me.
