Silicon Valley startup develops drones to modify clouds, boost PV plant output by up to 30%

A startup called Meteoric Technologies is working on a way to make clouds less reflective over solar power plants, so more sunlight reaches the panels below. The idea uses fleets of autonomous drones that fly into low- and mid-level clouds (roughly 1 to 5 kilometers up) and change their optical properties without chemicals, unlike traditional cloud seeding, which typically adds particles to clouds to trigger rain or clear fog. The company hasn't said publicly how the drones actually alter the water droplets.

Meteoric's models suggest the approach could boost a solar plant's annual electricity output by 10% to 30%, since cloud cover can cut incoming sunlight by 73% to 82% while passing overhead. The company estimates the extra generation could be worth $5,000 to $28,000 per megawatt, depending on the region of the U.S. power grid. In lab tests, a prototype dissipated 13% of an artificial cloud inside a test chamber. The company says its electric drones would cost far less to run than conventional aircraft used for weather modification, and it is also building AI-based forecasting tools to help predict where clouds will form and move.

This is aimed at utility-scale solar farms, not individual homes, and it's still early: the first large-scale field test is planned for 2027. Meteoric eventually wants to apply the same drone technology to weaken severe storms and hurricanes, with an initial experimental attempt targeted for late 2028. For now, there's nothing homeowners need to do, but the technology could eventually affect how much power large solar plants feed into the grid on cloudy days.
