Eastern Plains
Ground Mount

A farmhouse near Limon with more yard than roof. Twenty panels on a ground frame, a Keeper battery and a charger — the roof rails swapped for the frame in one click.

Custom Kit

Limon, CO

Completed April 2026

Yearly output

13.5kkWh

from twenty panels on a ground frame facing due south, with nothing to shade them.

The story

A big yard, a small roof and a long winter wind.

The Halversons run a pump, a shop and a car from a farmhouse whose roof faces the wrong way.

Ground frame, due south

Grid use −78%

01

Challenge

A north-facing roof, a 120-foot trench to the house and plains wind that rules out a light frame.

02

Solution

The Home + EV kit with the roof rails swapped for a galvanised ground frame in the cart — the wiring diagram updated with it. Two cable kits covered the trench run.

03

Result

13,500 kWh in the first year. The battery covers evenings and the pump; the house, the shop and the car bought 78% less from the grid.

“We thought ground mounts meant a custom quote and a month of waiting. It was a dropdown in the cart and two pallets on a Tuesday.”
