We’ve seen a few massive solar farms pop up out west, but it looks like Southern California Edison is taking a different approach: instead of cluttering up the desert, the company plans to build a distributed solar array on the rooftops of commercial buildings throughout SoCal. The plan is to spend $875M over five years to cover about two square miles of rooftop with the panels, which will alleviate stress on the grid by generating around 250 megawatts of juice, as much as a small power plant. That’s enough to light up 162,000 homes, but it’s still a little short of the record 280-megawatt Solana installation planned in Arizona — come on, Cali, let’s see a little fight.
