First Solar has reached an agreement with the Los Angeles (LA) County Department of Public Works to start installation of the solar modules at Solar Ranch One photovoltaic (PV) power plant in Antelope Valley, California, US.

Work on the ongoing 230MW power plant, which had been delayed pending the agreement between First Solar and the county related to the module code certifications, will now resume at the earliest.

LA County Public Works Deputy Director Dennis Hunter said the Department is responsible for ensuring that all applicable building codes are met by the project in order to protect the health and safety of county residents.

"Following our discussions, we are now confident in First Solar’s ability to meet our health and safety requirements," Hunter added.

Work on the project began in August 2011 and is expected to be completed 2013. Once completed the power plant will produce electricity to power 75,000 homes annually.

"As the first utility-scale solar PV project in Los Angeles County, this was the county’s first opportunity to apply its codes to a facility of this magnitude, which required significant time and effort for everyone involved," added First solar senior vice president of engineering, procurement and construction and operations and maintenance Jim Lamon.
