Cypress School & River Montessori Charter School Go Green Together

SolarCraft Helps North Bay Schools Go Solar

pr-UCP River montessori by SolarCraftNovato and Sonoma-based SolarCraft announced the completion of a 98.5 kW solar electric system for The Cypress School and River Montessori Charter School in Petaluma, CA. The building is owned by United Cerebral Palsy of the North Bay, who also sponsors the Cypress School. The solar power system is shared by the two organizations who will both see significant savings from clean energy for decades to come.

Designed and installed by SolarCraft, a leading North Bay solar provider for over 33 years, the solar power system was carefully installed to overcome a number of technical and logistical challenges to ensure student and staff safety at the busy campus. The SolarCraft Operations Team interconnected the solar systems to three separate meters, maintained an existing rigorous roof warranty, and planned and executed the installation very carefully to minimize interruptions of the day-today operations of the schools.

“The energy savings are providing additional funds for our enrichment activities including Cypress/River Integrated Play Groups, we’re very happy to be producing clean energy,” said Laura Briggin, Cypress School Director.

With the industry-wide price reductions seen over the last few years, the SolarCraft Energy system will pay for itself very quickly. Generating approximately140,000 kilowatt hours of energy annually, the system was designed to offset over 90% in their electric bills for the next 30 years.
Over the next 30 years, the solar system will prevent the emissions of more than 108 tons of carbon dioxide, equivalent to removing the air pollution produced by more than 235,000 miles of driving or CO2 removed by 93 acres of trees in one year.

SolarCraft offers unique financing options for non-profit organizations, solutions that are catered to the unique needs of each client that allowing them to capture the financial and environmental benefits of solar without any initial investment or ongoing operating costs. Ultimately the finance payments are typically less than paying PG&E, so the projects are saving money immediately.

School Solar Electric Installation Project Profile

petaluma solar panels, solar for schoolsLiberty School is generating its own electricity from sunlight thanks to its 44.7 kilowatt solar installation. Located in West Petaluma, CA, the school’s solar photovoltaic array will reduce their carbon footprint and save thousands of dollars in energy costs for years to come.

The system spans over 2,600 square feet on multiple rooftops, specifically designed by local architect Dan Hardin to accommodate solar.

Enphase Energy microinverters, donated by the Petaluma-based worldwide leader in microinverter technology, will work individually with the system’s 149 LG solar panels to ensure maximum energy production. The school received approximately $24,000 in rebates — one of the last California Solar Initiative rebates available before the program expired.

The system will power classrooms and administrative offices, providing about 70 percent of the school’s annual electrical needs by generating approximately 66,000 kilowatt hours of clean energy annually — enough each day to power over 20 average homes. The amount of carbon offset by the PV array is equivalent to removing 29 tons of harmful greenhouse gases annually. Over the next 30 years, the air pollution saved will be comparable to eliminating nearly 1.7 million miles of driving or the amount roughly 9 acres of trees could remove.

Customer Profile

Liberty School, nestled in the rural, dairy ranching area of Petaluma, 50 miles north of San Francisco in Sonoma County, serves pre-k through sixth grade students. Founded in 1857, Liberty School is the oldest school in continuous operation at the same site, with the same name, in Sonoma County. Liberty is the community hub where families meet and build relationships. Many families have been attending Liberty School for generations.

“We are very excited to finish our project with SolarCraft and Enphase Energy and begin saving our local community thousands of dollars that can be better used to educate the students of the Liberty Valley.”
