The Queensland Government says it is halfway towards one section of its 2020 target of generating 3000 megawatts of solar power from Queensland rooftops by 2020.

"November's peak of almost 16MW of solar generation capacity installed represents a 33 per cent increase on the year-to-date monthly average," Energy Minister Mark Bailey said on December 19.

"The four-month period from August to November included four of the five best months during 2016 for the number rooftop solar installations in Queensland."

Fairfax Media on Tuesday reported calls by University of New South Wales researchers for Brisbane to make better use of the roofs to collect solar energy.
