Instant water heater.
Used in conjunction with a solar hot water heater system, you have all the savings that you can imagine.
An instant (tankless) water heater is the best investment you can make after of course "solar panels" it doesn’t lose standing heat like a hot water tank and it’s only working when your solar panels didn’t produce enough hot water for use.

How does it work?
A high-powered electrical element (4500 watts or more) is inserted into a small container and will engage only when your open your hot water tap and the solar hot water isn’t on the right temperature to use in comfort.
Also, possible is a gas powered (natural gas or propane) tankless water heater, although, these are rather high prized.
