55kW SunPower Off-Grid System for Rocky Mountain National Park Trail Ridge Store
Independent Power Systems, Colorado has gone high! Specifically 11, 798 feet high!
IPS was commissioned by Xanterra to build an off-grid power system to power the Trail Ridge Store at the top of Trail Ridge Road (the highest continuous paved road in the U.S.) in Rocky Mountain National Park.
The goal for this system is to reduce dependence on the existing 125 kilowatt diesel generator that powers both the Trail Ridge Store and the Alpine Visitor Center during the park’s open season (typically June through October). The system is designed to provide close to 100 % of the energy needed by the Trail Ridge Store (which is operated by Xanterra).
IPS installed a 55kW SunPower solar array on a new cedar shake roof. The energy from the array is stored, processed and delivered to the store by means of the power center which is housed in a customized twenty-foot Conex shipping container located alongside the store.
The system consists of a 55 kW SunPower solar array, 30kW of inverter power and 135 kWh AGM batteries.
When wintertime snow buries everything under (up to) 30 feet of snow, three panels mounted vertically on the side of a wall – out of reach of snow pile-up – will trickle charge the battery bank.
This was a competitive bid win for IPS. As off-grid system specialists, we’re thrilled to have one of our systems in such a world-renowned park.
