Financial Institution Solar Electric Installation Project Profile

solar panels, santa rosa solar, commercial solar panels

By going solar, Redwood Credit Union will offset about 61% of their utility grid demand and save the company thousands in utility fees every year. The 662 kW solar electric system was installed by SolarCraft at Redwood Credit Union’s administrative offices in Santa Rosa, CA, powering their facility with clean, sustainable solar power.

The solar array consists of 2,036 Suniva 320-watt solar panels, spanning over 42,460 square feet on the rooftop installation. Covering the majority of the rooftop, the solar panels further reduce the building’s heating and cooling load by insulating and protecting the roof.

 SolarCraft designed and installed the system to produce up to 945,097 kWh of clean, solar power annually and will provide an effective long-term hedge against future utility rate increases. Installing solar, a cost-effective and sustainable energy solution, is the latest upgrade to the LEED-certified facility, which has served as the Credit Union’s headquarters since 2007.

Redwood Credit Union’s solar power system will generate enough electricity to power 148 average homes and will avoid production of almost 272 tons of carbon dioxide emissions per year, which is the equivalent of removing 15 million miles of driving over the next 25 years. That’s also comparable to the air pollution removed by over 54 acres of trees.

Commercial Solar Case Study, Congregation Shomrei Torah

House of Worship Solar Electric Installation Project Profile

Designed and built by SolarCraft, Congregation Shomrei TorahThe Congregation wanted to go solar for a few years for all the right reasons, and a new financing option introduced by SolarCraft that is very favorable to non-profits gave them a financial incentive as well. Essentially, the financing payments for the solar power are less than paying PG&E each month.

Designed and built by SolarCraft, the North Bay Synagogue’s system will reduce their carbon footprint while saving thousands in utility costs in the years to come.

The solar photovoltaic system is ground mounted on a hillside below the building and consists of 104 SunPower high-efficiency solar panels spanning nearly 2,180 square feet. The system’s solar panels convert sunlight directly into electricity and is expected to generate approximately 56,100 kilowatt hours of energy annually, reducing their PG&E bills by 90% and providing clean energy to the Synagogue.

The system’s solar electric panels allow the Congregation to generate enough electricity each day to power 17 average homes. It will spare the air nearly 25 tons of harmful greenhouse gases annually. Over 30 years, the air pollution saved will be equivalent to eliminating over 1.4 million miles of driving.
