This comes after Miliband approved three large solar farms on Friday evening that will generate a combined 1.3GW of electricity, the equivalent of powering 400,000 homes a year.
"We will do everything we can to encourage builders and homeowners to bring this win-win technology to millions of addresses across the UK so people can provide their own electricity, reduce their electricity bills and help tackle climate change at the same time," he added.
The relaunched Solar Taskforce will bring together industry experts and government with the goal of tripling solar power generation by 2030.
On Friday, Miliband approved three major solar projects - the Gateburton project in Lincolnshire, the Mallard Pass project on the border of Rutland and Lincolnshire, and the Sunnica project in Suffolk.
