Can I heat water with solar PV panels

Once the panels have created electricity you could connect this to an immersion heater to heat water. However, electricity is a very flexible form of energy and in most circumstances would be wasted being used to simply heat water. We would advise that home owners should heat water with solar thermal (water heating) panels.

Please note that these answers are designed to be appropriate for typical installations. The exact specification for your system will be detailed in your personal proposal.
