IKEA Home Furnishings will begin selling renewable energy products worldwide beginning in Britain. They have started selling solar panels made by Hanergy in their Southampton store. Stores in the country will then begin following suit in the coming months. A standard, all black 3.36 kilowatt system for a semi-detached home will cost 5,700 British pounds ($9,200) and will include an in-store consultation and design service as well as installation, maintenance, and energy monitoring service. The payback on a residential home solar system is about 7 years for the average UK home at average electricity rates. There are many financial and environmental benefits to using solar panels within homes.
