VISTA SOLAR TURNS DPR CONSTRUCTION INTO NET ZERO ENERGY CONSUMPTION IN SAN FRANCISCO

SANTA CLARA, Calif., June 12, 2014 /PRNewswire/ — Vista Solar today announced the completion of a 118-kW high efficiency SunPower solar power system for national builder DPR Construction.

NET ZERO ENERGY CONSUMPTION

The system’s designs and installation by Vista Solar, generates at least 158,000 kilowatt hours of clean energy each year. This grants DPR Construction net zero energy consumption at its new San Francisco office. As a result, solar meets 100% of the building’s annual electricity needs!

“Since this is DPR Construction’s first net zero energy designed regional office in the Bay Area, it was critical that we chose the right partner and solar technology to help us achieve our company goals,” says Mike Messick, project manager for DPR Construction.

DPR Construction partners with Vista Solar to meet a number of unique site challenges. In pursuit of net zero energy consumption, a solar system on the company’s highly-constrained rooftop becomes a reality. To generate the maximum amount of power within the limited roof space, Vista Solar installed high-efficiency SunPower X21/345 solar panels. These panels produce 75% more energy than conventional panels from the same space over the first 25 years.1

Additionally, Vista Solar installed Solar Edge inverters which pair DC optimizers with each panel. This combination produces as much power as possible, even when other panels are in the shade by the adjacent buildings. Plus, Silverback Solar racking for a custom design that accommodates the precise attachment points, 20-foot spans, varying elevations of the barrel roof and 19 solar tubes.

“While we regularly build much larger projects, the challenge of finding solutions for the site constraints and being able to take part in a net zero retrofit, right in our backyard, made this an inspiring project to work on,” said Vista Solar sales engineer Sam Kim. “Everyone wanted to see DPR succeed.”
