Last month, the millionth First Solar (FSLR) solar module was installed at the 550-megawatt (AC) Topaz Solar Farm owned by MidAmerican Solar.
When complete, the largest PV power plant in the world will field nine millions panels across thousands of acres on California's Carrizo Plains. Construction began less than one year ago. Expected to be complete in early 2015, PG&E will purchase the electricity from the Topaz project under a PPA. The solar farm was not the recipient of a loan guarantee.
The project was originated by OptiSolar. Some of the Topaz real estate was once intended for an Ausra CSP solar power plant.
