A Nevada task force wants to allow the state's early-adopter rooftop solar customers to go back to an older, more favorable rate structure.

The state's New Energy Industry Task Force voted Thursday to recommend a bill be drafted that would "grandfather" customers who applied to go solar by Dec. 31, 2015. The task force recommended letting customers keep the lower rates for 20 years from the date their system started operating.

Lawmakers could consider the proposed bill when they reconvene in early 2017.

The Public Utilities Commission voted to increase rates in December, saying it would eliminate a subsidy paid by customers without rooftop solar panels.

Rooftop solar companies dispute the cost-shift and cut jobs in Nevada, saying the rates made their business models unviable.
