The Palaszczuk Government has lost an appeal after its controversial solar panel regulations were ruled "invalid".

The Court of Appeal this morning dismissed the Government's appeal and awarded costs against the State.

Brigalow Solar Farm company director, and head of renewables for Impact Investment Group, Lane Crockett said described the Court of Appeal ruling as a "relief".

"This gives us the certainty we need to move forward, hiring the workers we need to keep building this solar farm," she said.

"When it's finished the Brigalow Solar Farm will provide enough clean power for more than 11,000 homes, it will avoid using the massive amounts of water that coal and gas-fired power consumes, and there won't be any toxic emissions."

The Opposition said the decision was a "win for regional jobs" and slammed the Labor Government's regulations and appeal as "another epic fail".

Shadow Minister for Energy Michael Hart said the court action was just more Labor waste.

"Queensland taxpayers' have a right to feel ripped off," Mr Hart said.

"Local workers can now be used for the lifting and mounting of solar panels under the supervision of electricians, instead of requiring fly in-fly out electricians from capital cities."

Clean Energy Council Chief Executive Kane Thornton said the development and introduction of the state government's regulation had been rushed.

"The industry should never have had to go through the courts to resolve something that could easily have been worked out with a full and proper consultation process," Mr Thornton said.
