Pressed for space, solar farms are getting creative

Solar power is expected to dominate global electricity markets in the next few decades, and already accounts for three-quarters of renewable energy capacity, according to the International Energy Agency. This year, BloombergNEF predicts solar builds will climb another 25%, adding more than 500 gigawatts of capacity.

All of that solar needs a lot of space. Powering just one megawatt of capacity requires at least five acres, meaning a 200-megawatt project (roughly 3,000 panels) takes up as much space as 550 American football fields. That calculus is one reason China — the world’s biggest solar market — is hosting many projects in remote desert regions. It’s also why the IEA expects rooftop and residential solar to expand faster than farms this year.
