About the Project
This summer, Dartmouth will continue its successful expansion of rooftop solar installations by adding solar arrays on eight buildings:
- Three residence hall facilities: Fahey-McLean, McLaughlin Cluster, and Russell Sage
- Four academic buildings: Moore Hall, Kemeny-Haldeman, Silsby, and Sudikoff
- Class of ’53 Commons
In aggregate these eight systems will have an electric generation capacity of 390 kW ac, and will generate almost 600,000 kWh electricity per year. Together, these eight systems will triple the amount of energy being generated by our campus photovoltaic (PV) systems installed to date. Once these are in production, approximately 10% of the buildings on campus will have photovoltaics, which will provide about 1.5% of Dartmouth’s annual electric use.
The eight buildings were selected based on their orientation to the sun and lack of shading by trees, the age and condition of the roof, and the ability of the roof and structure to support the solar system. All of the systems will be mounted on south facing sloping roofs, except at ’53 Commons which will be mounted on the flat roof area.
Like the PV panels installed on several buildings in the fall of 2017, these solar systems will be installed by ReVision Energy based on a 20-year contract in which we lease our rooftops to ReVision, who owns and maintains the systems. We then pay ReVision for the electricity at a lower rate than if we were buying energy off the grid. Dartmouth has the option to purchase the system and terminate the 20-year contract starting in six years.
Dartmouth’s engineering and utilities team is also actively working to identify viable sites for larger-scale solar PV systems to serve the campus. These larger scale systems will help us reach our goal to generate at least 20 percent of our electricity from campus solar systems.
