When Tesla acquired SolarCity in 2016, it inherited a factory deal with New York state worth nearly $1 billion in public subsidies.

It didn’t. First, Tesla off loaded solar panel production to Panasonic before the Japanese manufacturer pulled out in 2020. For years afterward, the Buffalo facility was mostly used for Supercharger components and Autopilot data labeling. Tesla’s solar deployment dropped so low the company stopped reporting it as a separate metric.</p></div>

<p>Tesla (TSLA) is constructing a new solar panel manufacturing facility in Brookshire, Texas, near Houston, co-located with its Megapack Megafactory. This marks a significant step towards Tesla's goal of achieving 100 GW in annual solar manufacturing. The development follows a history of challenges in Tesla's solar manufacturing efforts since acquiring SolarCity in 2016.</p>

- Tesla is constructing a new solar panel manufacturing facility in Brookshire, Texas, alongside its ongoing Megapack Megafactory.  
- This development is part of Tesla's goal to achieve a 100 GW annual solar manufacturing target, marking a significant step in its long and challenging history with solar production.  
- Previously, the company faced setbacks with its Buffalo facility, which was intended to be the largest solar manufacturing plant in the Western Hemisphere but ultimately did not fulfill its promises.
