The Conejo Recreation and Parks District is constructing four carports with solar panels that are expected to save it $3.4 million in electricity costs over 25 years.

The panels are being installed by SolarWorld AG, a German manufacturer of solar panels, with financing from Sustainable Power Group, a Salt Lake City renewable energy development firm.

The engineering, procurement and construction division of SolarWorld in Camarillo will oversee the building of the carports in the parking lots of Borchard Community Park, Dos Vientos Community Park, Thousand Oaks Community Park and Conejo Creek South Park. Construction costs were not disclosed.

Kevin Kilkelly, president of SolarWorld Americas, in Hillsboro, Ore., said the project combines SolarWorld’s solar technology and construction experience with Sustainable Power Group’s financing capacity.

“The project also highlights a growing trend among U.S. park districts,” Kilkelly said in a prepared statement. “Long-time stewards of the environment, these organizations understand that solar power can also play a role in financial stewardship.”

The carports will generate between 71 kilowatts to nearly 170 kilowatts of power.
