School Solar Electric Installation Project Profile
Joining many other green Marin County Schools, Ross School has gone solar. Ross School chose SolarCraft to design and install their 111.7 kilowatt solar electric system, which will provide enormous savings to their facility. The project includes the newly rebuilt main school building and the gymnasium on the property — now powered by the sun.
Phase One of the system was installed on the main building during the school’s massive renovation. It consists of 312 American-made Sharp 240 watt solar modules. The second phase was later installed on the newly completed gymnasium and consists of 154 modules. The school is now able to utilize clean energy that is sustainable and price stable.
The solar panels are mounted on the steel, corrugated roof using an engineered non-penetrating mounting system that is low-profile and attractive on the new buildings. The panels span over 8,174 square feet and help insulate and protect the roof.
The new system will reduce the school’s utility costs by thousands every year, while reducing the load on the local utility grid. Excess power generated during the day is banked by PG&E for credit towards future use.
The solar energy system will generate approximately 161,317 kilowatt hours annually, generating enough clean energy each day to power 56 homes. Over the next 30 years, the air pollution saved will be equivalent to eliminating over 6.8 million miles of driving and spare the air nearly 3,000 tons of carbon emissions.
