Meteoric Develops Drones to Dissipate Clouds Over Solar Farms for Increased Power Output

Cloud Dissipation for Solar Efficiency

Meteoric, a startup founded by University of Cambridge engineers and supported by Y Combinator, is developing autonomous drones designed to operate within low- and mid-altitude clouds near solar farms. The goal is to dissipate these clouds to optimize power production by allowing more sunlight to reach solar panels.

Mechanical Alteration of Cloud Droplets

According to Mete Karslioglu, Meteoric’s CEO, the drones will mechanically alter water droplets within clouds, reducing their reflectivity. This process aims to increase the amount of sunlight hitting the solar panels below. The company states that low and mid-level overcast clouds can cut incoming sunlight by 73-82%, and their method seeks to recover this lost sunlight without requiring new infrastructure.

Projected Impact on Solar Generation

Meteoric's cloud-loss model suggests that this process could increase annual generation from existing solar assets by 10-30% across major U.S. grid regions. This increase is estimated to be worth approximately $5,000-$28,000 per megawatt. The company also states a long-term goal of reducing the intensity of severe storms and hurricanes.

Cost-Effective Solution

While the specific method for cloud dissipation remains undisclosed, Meteoric claims to have a working prototype that dissipated an artificial cloud by 13% in cloud-chamber tests. Existing cloud dissipation techniques, such as dispersing carbon dioxide or mechanical mixing with helicopters, can cost $2,000 per hour or more. Meteoric's electric drones are projected to cost only $30 to $60 per hour, presenting a more economical alternative.

Addressing Solar Power Challenges

This approach addresses a significant challenge for solar power, where fluctuating weather patterns impact energy output. Other entities are also exploring solutions, such as Reflect Orbital's proposal for an orbital mirror to extend daylight or Meta's plans for solar collecting satellites.
