6 FAQs about [Divert excess solar power to hot water]

Can a solar power diverter heat a hot water tank?

Instead, using a solar immersion diverter, you can heat your hot water tank using any surplus energy from your solar panel system. Solar power diverters work by monitoring the amount of electricity being generated by your solar panel system, compared to how much energy you’re using in your home.

What is a solar power diverter?

A solar power diverter, also known as a photovoltaic (PV) immersion controller, is a smart device used with solar panels and a hot water immersion heater. It maximises the use of free and abundant solar energy by directing excess electricity generated by the panels to the immersion heater to heat water, rather than exporting it to the grid.

Does solar diverter hot water affect electricity?

That means there’s no impact on electricity for your home, as it’s still prioritised over solar diverter hot water. Solar diverters are affordable, quick to install, and pay for themselves over time. They’re the perfect fit for any home with its own solar panels and a hot water tank (used for conventional and system boilers).
