How will the obbb impact residential battery owners?
Wannabe residential battery owners will likely feel the most immediate impact of the OBBB. Updates to the 25D residential solar tax credit, which covers solar panels, solar water heaters and related property like home battery storage systems, have significantly shortened the timeline for homeowners to access the credit.
How is business personal property taxed?
The tax is based on the property's fair market value. Some states do not tax business personal property, while others exempt or exclude some renewable resource property from taxation. Not all states classify BESS as a renewable energy facility for purposes of a property tax exemption or exclusion.
Are residential batteries a good investment?
