Business, Multi-Family or Non-Profit Property? Save with Solar

Occidental Power installs photovoltaic systems for commercial and non-profit properties. If you own a business, multi-family building or if you manage a school or other non-profit facility, get paid back after you install a photovoltaic system!

How does Solar Photovoltaic Work?

You've heard all about solar photovoltaic but what is it really? Here's a simple explanation about what it is and how it works:

  1. Solar cells, also known as photovoltaics turn sun energy ("photo") into electricity ("voltaics").
  2. The electricity generates direct current (DC).
  3. Inverters convert the direct current to alternating current (AC).

These solar cells are built into an array of panels to generate enough electricity for buildings onsite,

Your ROI

Many Bay Area solar system installations are connected to the local utility grid, in other words. net-metered. This allows you to generate your own electricity and sell unused energy back to the grid. Utility intertied systems collect and add power to the utility grid during the day to offset power use at night. During daylight hours, the meter runs backwards when the solar panels produce more energy than the facility is using. You are in a sense using the grid as a giant battery. At night your meter rolls forward as you consume power from the grid. If you produce as much power as you consume you will not have a utility bill. The utility only charges for the net difference of power consumed and power produced.

Occidental Power is recognized in the city for its high quality installations for commercial and non-profit buildings.

FEATURED INSTALLATION: French American International School, San Francisco

Time-lapse video of our solar energy system installation on the rooftop of the French American International School at 150 Oak Street. We designed, engineered, and built this system on 6 rooftops equalling about 11,340 square feet. The National Center for International Schools (NCIS) implemented this project in the summer of 2015. The NCIS manages the operations of the Chinese and French American International Schools.
