The American Lung Association in San Diego, Calif. will get about a quarter of its electricity from a new donated solar photovoltaic array.

The installation was fitting for the nonprofit dedicated to fundraising for researching and promoting good lung health.

“Clean renewable technologies will, in time, reduce the serious health threat of air pollution,” said Jane Warner, president and CEO of the American Lung Association of California. “We thank our solar partners for making this generous donation to help our organization take part in building a sustainable future.”

Trina Solar, Everyday Energy, Sonepar, ESSCO Wholesale Electric and Zep Solar combined forces to donate the panels, engineering, design and installation of the 10.5-kilowatt system, according to a release from the association.

“This project allowed a group of businesses to give back by sharing their expertise and products and provide a solar system free of charge to the American Lung Association in California,” said Scott Sarem, CEO of Everyday Energy. “This project is an excellent example of a community working together to walk the walk with respect to renewable energy and clean air.”

All of the companies involved in the donation have a local presence and work in the Southern California community.

San Diego Mayor Bob Filner helped the community celebrate in unveiling the new solar array last week.

The rooftop array is expected to produce 16,191 kilowatt hours of electricity a year and reduce the building’s toxic chemical emissions by 256 tons over the next 25 years. That’s the equivalent of planting 10,220 trees, according to the release.
