A £35 million solar farm said to be the biggest in Britain has been connected to the National Grid.
More than 130,000 panels have been put on 150 acres at Wymeswold Airfield.
Developer Lark Energy said the farm – built in less than eight weeks – was expected to produce emission-free energy for 25 years.
It will produce enough energy to supply 7,500 homes.
The company said it chose the site as it was relatively secluded and was not overlooked by properties.
The project received planning approval from Charnwood Borough Council in November.
Lark Energy managing director Jonathan Selwyn said: "All you can hear is the sound of bird song, there is no noise coming from the solar farm.
"There is no smoke, no emissions, it is just absorbing the sunlight and turning it into clean power and will be doing that for the next 25 years.
"As the largest solar farm in the UK, the project has not been without its challenges, both technical and weather-related. It is a testament to the teamwork of the parties involved in its development and delivery that it was completed and connected on time."
Edward Packe-Drury-Lowe, manager of Prestwold estate, on whose land the solar farm is sited, said: "The solar park will add another diversification to the estate, with energy joining food production and leisure".
Wymeswold parish councillor Shaun Bokor said: "I think it's a useful application for a piece of land you couldn't do anything else with. It generates energy in what could be described as a nice way. It's close to the ground and unobtrusive – sheep can graze under it."
Mike Herington, owner of the Windmill Inn, in the village, said: "The general feeling is it's a good use of the land.
"It's not an eyesore for the village. What can be wrong with renewable energy? We just need some sunshine."
The airfield also has a race track and an HGV training centre.
Bill Hughes, who runs Hughes HGV Driver Training, said: "It is no problem to us. It's not obtrusive. A lot of people don't even know it's gone up.
A spokesman for F1 Karting, which runs an indoor track at the airfield, said: "It hasn't impacted us at all.''
