Tesla has formally requested property-tax breaks to site a $10.1 billion solar manufacturing facility — internally designated "Project Crystal Sun" — outside Houston, Texas. The company is evaluating five parcels of land in Richmond, Texas, situated near the operational Cutlass Solar project, and has applied for financial incentives through the state's Jobs, Energy, Technology and Innovation (JETI) program. The filing represents a notable expansion of Tesla's solar energy business, which has focused on panel installation and its Solar Roof product line since the company's 2016 acquisition of SolarCity but has not previously manufactured its own upstream solar components.

According to documents filed with the Texas Comptroller last month by advisory firm Kroll, Tesla is also exploring additional sites across the county. The company stated it intends to begin construction this year and achieve commercial operations by Q1 2029 at a facility dedicated to manufacturing "photovoltaic solar cells and/or assembled solar modules."

Operations at the proposed site would "focus on producing finished photovoltaic products" for deployment across all markets. Kroll indicated that Tesla will require wafer and ingot manufacturing equipment, metallization and printing lines, cell testing equipment, and additional cleanroom and safety systems. The facility is projected to generate 9,712 permanent full-time jobs along with more than 1,000 construction-period positions.

The filing aligns with prior statements by Tesla CEO Elon Musk, who has expressed the goal of working toward "100 GW a year of solar cell production" within the United States. It also comes amid a broader wave of domestic solar manufacturing investment accelerated by the Inflation Reduction Act of 2022, which established the Section 45X advanced manufacturing production credit providing per-unit tax credits for U.S.-produced solar ingots, wafers, cells, and modules.

Planned Manufacturing Scope

Based on the specified equipment requirements, the Richmond facility would likely perform silicon ingot pulling, wafer slicing, cell production, and final panel assembly. That capability would place it well beyond the scope of most current U.S. solar manufacturing operations. The domestic market is predominantly focused on panel assembly and continues to rely on imported solar cells and other upstream silicon components, which remain subject to U.S. trade duties including Section 201 safeguard tariffs.

Only a small number of companies currently manufacture upstream portions of the silicon solar supply chain in the United States. Corning produces wafers in Michigan, while solar cell manufacturing is conducted by Canadian Solar in Indiana, Suniva in Georgia, and ES Foundry in South Carolina. Consolidating every silicon solar production step within a single campus would offer Tesla meaningful cost advantages.

At present, only one other U.S. factory is expected to carry out the same end-to-end process as Tesla's proposal: Qcells' ingot-to-panel facility in Cartersville, Georgia. Qcells has invested more than $2.5 billion over the past three years to build that site, which currently operates only at the cell and panel assembly stages. Ingot and wafer production has not yet come online. The fully integrated Qcells facility is expected to have an annual manufacturing capacity of 3.5 GW.

Assessing the 100 GW Target

Judged solely against Qcells' spending levels, it appears improbable that Tesla could realize Musk's aspirational 100 GW of manufacturing capacity with a $10 billion investment. Solar Power World contributor Finlay Colville conducted a more detailed analysis earlier this year to estimate what achieving triple-digit gigawatt capacity would actually require.

Colville examined Jinko Solar's 56-GW ingot-to-module factory in China, constructed between 2023 and 2025, which cost approximately $8 billion to build. He noted that Chinese projects benefit from comparatively streamlined project siting and land acquisition processes. However, Colville also observed that Tesla would hold an advantage in 2026, as production equipment costs have declined roughly 30% since Jinko completed its facility, generating savings on that front.

Ultimately, Colville determined that Tesla would need to invest approximately $16 billion to achieve 100 GW of manufacturing capacity in the United States. Additional expenditure would also be required for ongoing repairs, maintenance, and line upgrades as n-type solar cell technologies continue to advance.

Based on that analysis, the proposed Texas factory — even at $10.1 billion — would in all likelihood fall short of producing 100 GW of solar panels annually. For scale, 100 GW would represent nearly thirty times the planned annual capacity of Qcells' fully integrated Cartersville facility.
