Is Solar Water Heating Available

We have been on a similar path to yours. While our net usage of grid energy is zero over the last 3 years, we still depend on the grid for electricity at night. I would be interested in hearing what you have decided to do to resolve that issue? We are planning on transitioning via a hybrid system but the local installers don't seem to be particularly knowledgeable about it.

We had our solar hot water heater installed about a month ago now and are quite happy with it so far. We are hoping that regular maintenance will prevent the problems with mineral deposits.
