A record number of homeowners had solar panels installed this month, according to energy regulator Ofgem.
The devices have been fitted to 2,257 homes so far during August, up from 1,700 in July and 1,400 in June.
More than 6,688 homes have had solar panels fitted since April, when the government's scheme to reward people who generate their own energy altered.
The feed-in tariff system now enables homeowners to receive 41.3p for every unit of energy they generate.
This is regardless of whether they use the energy or sell it back to the National Grid.
