Tesla Building 100 GW Solar Panel Factory in Texas: Report

Brookshire, Texas, 2021

Tesla appears to be preparing to build a massive solar panel manufacturing operation near Houston. The new facility would be located in Brookshire, the same site where Tesla is already constructing its upcoming Megafactory.

If the reported plans move forward as outlined, the project could transform Tesla into one of the largest solar manufacturers in the world.

The details come via a report from Electrek, which claims Tesla’s plans include the ability to produce up to 100 gigawatts (GW) of solar products annually, covering the entire manufacturing process from wafers and cells to fully assembled solar panels.

Tesla has also reportedly invested heavily in manufacturing equipment for the project, including machinery sourced from Maxwell in a deal said to be worth nearly $3 billion. The move would dramatically expand Tesla’s role in the renewable energy supply chain and support the company’s broader push to integrate solar generation with battery storage products like Megapack and Powerwall.

The scale of the reported plans is massive, especially compared to Tesla’s existing solar manufacturing operations in Buffalo, New York, which currently operate at a much smaller capacity of 300 megawatts (MW).

The Brookshire area has been tied to Tesla for several years. Back in 2023, Tesla quietly leased more than one million square feet of industrial space at Empire West Business Park, fueling speculation the company was preparing a major manufacturing or logistics expansion near Houston.

That later came to fruition when Tesla announced plans to establish its third Megafactory in Brookshire, located roughly 35 miles (56 km) west of Houston. The facility is expected to open later this year create around 1,500 jobs to support Tesla’s rapidly growing Megapack business.
