Regions continue to hungrily build out utility-scale solar PV projects worldwide. Utility-scale installations this year already exceed a record 6 GWp and are on track to top 8 GWp, up from 5.6 GWp in 2012 and 3.6 GWp in 2011. That's a market value of " well over $10 billion," says Wiki-Solar founder Philip Wolfe, which tracks this sector.
