In the past two years Kenya has experienced several nationwide blackouts  and don’t get me started on the daily power cuts. You wake up in the morning, it’s dark, no hot shower for you! Irritating right? Well, this is why you should install a solar water heating system in your home.

Yes, a quality system is expensive at face value, but worth your while: A one time investment. Some systems go for as low as Ksh.60,000.  I can assure you something will always be faulty leading to eventually having to replace one part of the system or the other.  A quality system costs an average of Ksh.130,000.

Solar water heating (SWH) is the conversion of sunlight into heat for water heating using a solar thermal collector. A variety of configurations are available at varying costs to provide solutions in different climates and latitudes. Solar water heaters are widely used for residential and some industrial applications.

Most SWH installations require backup heating. The amount of hot water consumed each day must be replaced and heated. In a solar-only system, consuming a high fraction of the water in the reservoir implies significant reservoir temperature variations. The larger the reservoir the smaller the daily temperature variation.

Equipment components must be insulated to achieve full system benefits. The installation of efficient insulation significantly reduces heat loss. The most efficient PV pumps start slowly in low light levels, so they may cause a small amount of unwanted circulation while the collector is cold. The controller must prevent stored hot water from this cooling effect.

Evacuated tube collector arrays can be adjusted by removing/adding tubes or their heat pipes, allowing customization during/after installation.

Installing a Solar Water Heater ensures hot water throughout the year since the system works all year round.

Sunlight is free, so once you’ve paid the initial installation cost, your hot water costs will be reduced leading to a reduced energy bill.

An additional advantage for all the environment lovers is the lower carbon footprint. As solar water systems are a green, renewable heating system, they contribute to the reduction of carbon dioxide emissions.

There are several companies in the country offering quality Solar Water Heaters . Hope this blog will help you start your eco-friendly journey!
