Dont waste your solar power by letting the grid have it back for free , use it yourself. As they say use it or loose it. This project is a way of getting hot water from your spare capacity from solar panels without using an Immersun unit. Total cost of the parts for the project to heat your water if you do it yourself is about £50.00.
