The U.S. Senate Finance Committee has included manufacturing incentives for domestic solar tracker and inverter manufacturers into its draft National Reconstruction Plan (BBB) ​​budget reconciliation bill.

The draft was released on December 11, expanding the advanced manufacturing production credit portion of the bill to include support for domestic manufacturing of solar modules, batteries, silicon wafers, and solar-grade polysilicon.

The updated text shows that the credit lines of these devices are consistent with the previous version, but the phase-out time has been postponed by two years from 2026 to 2028. This also applies to tracker devices and inverters.

According to the Finance Committee’s proposal, the tracker manufacturing tax credit will be:

At the same time, the inverter tax credits are as follows:

As the Democrats in the Senate continue to negotiate on the BBB, it is not clear how much the bill’s solar manufacturing incentives will include, and the party needs the support of all 50 senators to pass it.

Other solar support measures included in the package are the expansion and expansion of the investment tax credit (ITC)-which also applies to independent energy storage systems-and the restoration of the production tax credit (PTC) for solar power plants.

PV Tech Premium last week discussed how the policy support contained in the bill can accelerate the deployment of solar energy in the United States while supporting domestic manufacturers.
