San Francisco-based Perpetual Power has announced the completion of a 416kW DC solar installation on a cold-storage building in Contra Costa County, Calif. The Markstein Sales Co., Antioch, Calif., a family-owned business and distributor of Budweiser and other beverages, decided to install solar power on its facility to reduce its energy costs while contributing to the protection of the environment.

The solar system was designed and installed by Perpetual Power and is the first system to use its new proprietary Oasis roof-mounting system.
