Water for the showers in the campground restroom is heated by a solar-water heating system.

The Park has two solar energy systems. One is a solar-water heating system for the campground restrooms and the other is a photovoltaic (PV) system on the north entrance station.

Campground Restroom

Water for the showers is heated by a solar-water heating system.

An antifreeze mixture is circulated through the two solar panels on the roof which heats the mixture. A heat exchanger in the mechanical room is used to transfer the heat to water which is stored in a hot water tank until needed.

If the water is not hot enough, a propane-fired instantaneous water heater is used to bring the water up to the desired temperature.

North Entrance Station

A photovoltaic system was installed on the roof of the entrance station to provide power for lights, an evaporative cooler and a cash register.

In 2000, an entrance station was built at the north entrance to the park.

This new entrance station is 6 miles from grid power and has lights, an evaporative cooler and a cash register. A PV system was installed on the entrance station to provide power for these loads.

Driving to the north, heading out of the park, the PV modules on the roof are not visible, which reduces the change of vandalism.

The inverter, charge controller, low voltage disconnect, safety disconnect, and batteries are all mounted in the counter in the entrance station.
