Jan 2 (Reuters) - SunPower Corp said it sold two large solar projects in California to a company controlled by Warren Buffett’s Berkshire Hathaway Inc, and would receive up to $2.5 billion in proceeds and related contracts.
The Antelope Valley solar projects, which SunPower says is the world’s largest photovoltaic power development, have been sold to a unit of MidAmerican Energy Holdings Co, a part of Berkshire Hathaway.
Construction for the projects — with a combined capacity of 579 megawatt — will begin in the first quarter of 2013 and is expected to be completed by the end of 2015.
SunPower will get between $2.0 billion and $2.5 billion for the projects including charges for designing, installing and constructing the projects, the company said in a regulatory filing on Wednesday. 
Shares of SunPower were up 9 percent at $6.14 in afternoon trading on the Nasdaq.
