While we know that solar energy is that which is obtained from sunlight, a geyser on its own part is a hot spring that sends steam and water into the air. A solar geyser is a technological device that generates heated water from sunlight through a process called convection.

Solar geysers are renewable energy products because they rely on solar energy to work. Perhaps you own one or have seen one before. In any case, it’s an efficient way to use natural sources and go green.

How does it work?

First, solar geysers are fitted with solar collectors which are mounted on the roof of a building for sunlight. Next, the tank and heat exchanger is placed by the conventional water heater. Having done that, the pipe and glycol loop is then installed- this is to contain the heat in the fluid. Once controls are installed, the system is filled with water and glycol lines are insulated, your solar geyser is ready for use.

What do you need for a solar geyser?

It might sound exotic but solar geysers are made from familiar materials such as your solar panels, tanks, and pipes. These are the main components needed to generate hot water through sunlight especially during cold weather and for countries that have low temperatures.

In the current age of renewable energy, many African countries have successfully employed mini-grids to increase electricity access in their isolated and rural regions. This has proved to be one way to fast-track their energy security aspirations.

The solar geyser market is a fast-growing one with a growth projection rate of more than 5.1% over the period of 2020-2025. Middle-East and Africa are expected to record the highest growth. Even now, countries like South Africa and Zimbabwe among others have embraced the use of solar geysers.

How can it benefit us?

Asides from it being a very good option to heat water in a clean way rather than burn fossil fuels, the use of solar geysers is a way to mitigate climate change one household at a time. Heating water through this source does not emit pollutants to the air and also reduces carbon footprint.

Solar geysers get free energy directly from the sun which cannot be depleted, unlike fossil fuels which you need to replenish as often as you use them. Thus, using the device also saves you money. Its power does not wear off as it will continue to heat water both on rainy and cloudy days.

Remember the saying ‘the less you use, the less you spend’. This is true for solar geysers as they can help you reduce electric bills and you get hot water at all times.

This is especially noteworthy since electric geysers have been found to consume around 40 to 60 percent of electricity. How expensive that will be if you have to pay electric bills! Solar geysers are the future, a technology built to save and serve the ecosystem.

More importantly, they are tools that can be useful in the fight to slow down global warming. After all, we need all the help we can get. Oh, and yes, solar geyser is just a fancy term for solar heaters.
