10 times solar water heaters as solar panels

When we talk about solar energy, most times we discuss electricity from solar panels.

But solar energy has been contributing to low carbon energy use long before solar panels made their appearance – in the form of solar water heaters.

As of 2023, while there are around 25 million rooftops using solar panels for electricity, there are an estimated 250 million rooftops using solar water heaters worldwide.

Solar water heaters, in other words, are present in ten times the number of houses as solar power systems!

The simple and maintenance free operations of solar water heaters, combined with the fact they can be used in most parts of the world – including in cold regions – have ensured that a large and growing number of households worldwide use solar water heaters as a clean, zero carbon source of domestic water heating.
