[QUOTE="johnb2713, post: 528628, member: 35153"] The cost was a fraction under £11k I have calculated via a spreadsheet based on last years consumption, todays prices and predicted solar generation based on each month, my payback will be less than 4 years. The predicted generation for this area so far has been slightly pessimistic too. When the prices go up again in October and January that will bring the time down further. I have not factored into calculations were not using gas for hot water at the moment all of that is done by the immersion heater. I'm currently building a 16kWh battery that I'm going to AC couple into the system, charge on off peak rate so that we can use it throughout the day during winter to run heatpumps. This will bring the payback time down even more [/QUOTE]
