Warren Buffett Buys World's Largest Solar Project from SunPower for $2.5 Billion
The SunPower facility has already sold its power under long-term contracts to SoCal Edison:  <a href="http://www.elp.com/articles/2013/01/antelope-valley-solar-projects-will-generate-579-mw-for-southern-california-edison.html" rel="nofollow">http://www.elp.com/articles/2013/01/antelope-valley-solar-pr...</a><p>So from Buffett's perspective this just looks like a bond.
