SOLAR panels have been fitted to Southsea Library’s roof to help keep electricity costs down.
The panels, which cost £22,630 to install, should save £3,620 each year – paying back the full cost of installation in under seven years.
Experts say over 25 years the additional electricity produced and fed into the national grid together with energy savings sees a profit of £118,00, thanks to the government’s ‘feed-in’ tariff rate.
Similar installations are planned for the roof of Central Library, Portsmouth, where estimated profits would be nearly £200,000 over the same period.
The city’s head of environment Cllr Eleanor Scott said: ‘This is fantastic clean energy news for our environment and good news for the city’s local taxpayers who will benefit by way of reduced energy bills for these public buildings.’
