Tesla Plans Massive 100 GW Solar Factory in Texas

May 20, 2026 — Tesla Reportedly Expands Into Massive Solar Manufacturing in Texas.

Tesla is reportedly planning to build a massive solar manufacturing facility in Texas, according to industry reports, marking a major expansion of its renewable energy and battery business.

The proposed project is expected to be located near Houston, in the Brookshire area, where the company is already developing its Megafactory operations.

Target capacity of up to 100 GW annually

The planned facility could reach an annual production capacity of up to 100 gigawatts (GW) of solar products, covering the full manufacturing process from raw materials to finished solar panels.

This would include vertically integrated production such as wafer processing, cell manufacturing, and final panel assembly, making it one of the largest solar manufacturing operations globally if completed as planned.

Major investment in equipment and supply chain

Reports indicate that Tesla has been investing heavily in manufacturing infrastructure for the project, including advanced production equipment sourced from suppliers such as Maxwell, in a deal reportedly valued at nearly $3 billion.

The facility is expected to support Tesla’s broader strategy of scaling its energy division alongside its electric vehicle and battery businesses.

Expansion of Tesla’s energy ambitions

The project aligns with Tesla’s long-term goal of increasing its presence in renewable energy markets, particularly as global demand for solar power and energy storage continues to grow.

If completed, the Texas facility would significantly expand Tesla’s solar production capabilities and strengthen its position in the global clean energy sector.
