A Nevada judge has ruled the state's energy regulators used what he called "unlawful procedure" in adjusting rates for rooftop solar customers.

The Las Vegas Sun reports a district court judge ruled customers weren't given enough of a notice before the Nevada Public Utilities Commission decided to change net metering rates.

Last year, the regulatory agency lowered the reimbursement rate for rooftop solar customers for the electricity their panels generate.

His ruling calls for the PUC to make adjustments to its policy.

However, the ruling does not change the current rate structure as amended late last year.

The commission is set to meet on Friday to discuss potential changes to the rooftop solar rate structure.

The PUC, NV Energy and rooftop solar providers have been working to hash out a new agreement that would allow existing customers to maintain the old rate system for a fixed amount of time.

The Sun reports the PUC was pleased with the judge's ruling since it puts the ball back in their court.
