- Create 300kWh – 320kWh (kilowatt hours) of electricity per month for the 25+ year life of the system
- Prevent 3.2 tons of carbon dioxide from entering the atmosphere every year.
- Save 1.6 tons of coal from being mined, processed, and disposed of each year.
- Learn more about planning and developing renewable energy in our area
- Begin work towards progressive energy and finance policies here in the High Country
- Help mitigate transition cost for the most vulnerable rate payers
- Dispel misinformation and confusion around renewable energy
Technical Details of the Solar Electric/Photovoltaic System

The Sharp 216 W Solar Electric/Photovoltaic Panel
The solar electric/photovoltaic system is comprised of 11 216 W (Watt) solar electric panels for a total system power of 2.376 kW (kilowatts). The panels are produced here in the United States by Sharp, one of the world’s leading manufacturers of solar electric/photovoltaic panels. Each 44 pound panel carries a 25-year limited power output warranty and will convert 13.3% of all sunlight collected in to clean green pollution free electricity.

The Unirac Rapid Rac System
The panels are mounted on the roof of The Greenhouse using a Unirac ballasted racking system. The racks maintain their placement on the roof by the application of weight at their bases, and thus, do not require any roof penetrations. This flexible mounting configuration eases roof maintenance and enables the system to be uninstalled and moved in an uncomplicated fashion.
The system is not yet connected to New River Light and Power’s electrical grid (i.e. grid connected), but we are diligently working with New River Light and Power on a grid interconnection. Once the solar electric system is connected to NRLP transmission system, every watt of electricity produced will be used by The Greenhouse or sold to other homes and businesses in the community requiring electricity. The power production of the system is currently monitored via the Internet.
System Cost and Financials
About The Greenhouse
- 80% – 100% of all the electricity used by the GreenHouse is provided by a community owned solar electric/photovoltaic system installed on the the office’s roof.
