Pressed for space, solar farms are getting creative
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.
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.
