Can solar water heating and solar photovoltaic panels be used together?

Solar water heating and solar photovoltaic panels can be used together, provided your building has sufficient space, or independently. Solar PV panels can also be used independently to power a traditional electrical water heating system.

What is solar water heating?

Solar water heating (or solar thermal) uses sunlight to heat the water you’ll then use in your bathroom or kitchen. Even in cloudy Britain, solar energy can meet more than half of your annual hot water demand. Solar water heating should not be confused with solar photovoltaic (PV) technology, which produces electricity.

Are solar panels a good alternative to solar water heating?

Solar PV panels offer a number of advantages beyond solar water heating. Due to their simpler design – solar photovoltaic panels have no moving parts – they need little long-term maintenance. It’s also possible to use a solar panel system to heat your building’s supply of hot water.

Can solar panels heat water?

The output of solar PV panels can be diverted to heat water, but solar water heating is more efficient. This means it will take up much less roof space than PV panels would for the same energy output. Your home could even have both solar thermal and solar PV, to generate the largest amount of renewable energy from your available roof area.

What is the difference between solar water heating and solar photovoltaic?

Despite this, there are big differences between their results and the technology involved. Despite looking somewhat similar to solar photovoltaic panels, solar water heating technology operates very differently. Instead of converting sunlight into electricity, solar water heating technology uses the heat from the sun to heat water.

Where should a solar water heating system be installed?

Rooftop panels are the most common, mounted in a spot that will minimise pipe runs to the cylinder. Or you could place panels at ground level if they’ll have a clear outlook. See the related questions below for more on planning permission for solar panels. How does solar water heating work? A solar water heating system involves three main parts:
