Solar collector panels: Greenskies
Worcester, part of the Bosch Group, launched Greenskies Solar, its first renewable-energy product for hot water heating, in 2005. In 2006, new high-performance panels were specially developed with simple connections and lightweight materials to aid installation. The new additions to the range offer both portrait and landscape versions to maximise flexibility and installation choices. Specifically tailored to meet the needs of the UK market and developed in line with helping meet the government target of reducing CO2 emissions by the new figue of 80% by 2050, Worcester Greenskies solar panels have been designed as the ideal partner to the SEDBUK A-rated Greenstar condensing regular and system boilers.
Worcester now has fitting solutions for on-roof, roof integration, flat roof and wall mounted at 45° situations. The panels are designed to be installed in homes with systems that store hot water. A Greenskies solar system utilises twin-coiled cylinders. One heat-exchanger coil is heated by the boiler, and the other by the solar panels. The Greenskies system has its own pump, expansion vessel, pressure relief valve, air vent and controller.
A simple controller allows the user to select the temperature required at the hot-water cylinder. The controller then automatically decides when to run the pump to bring heat from the panels to the cylinder.
