Assuming no other changes in estimates, and with the return reduced from 9% to 7%, this continues to represent a positive investment level, and carbon savings are considerable. The price of panels is falling by 20%-30% and efficiencies improving, so payback period could still be about 9-10 years.  Details from Joan Harris joanie@exeter.anglican.org (01392-294940)

Church buildings which already have their panels installed independently and are operating include St. Andrew’s Minster and St. Matthias Church Hall in Plymouth,the Boniface Centre at Crediton, Ipplepen Church Hall,  Lympstone Parish Church and Wonford Methodist Church.
