The residential solar sector looks to fight for its survival, as the Senate didn't significantly water down Trump's tax bill.

(Reuters) -U.S. solar stocks dropped in premarket trading on Tuesday after a Senate panel proposed a full phase-out of solar and wind energy tax credits by 2028, as part of changes suggested to President Donald Trump's sweeping tax-cut and spending bill.

The Senate version of the bill includes a provision that would fully phase out both solar and wind power tax incentives by 2028. It does, however, keep incentives for nuclear, hydropower and geothermal energy for longer.
