Everything You Need to Know About Solar Geysers

Most Solar Ray customers save between 30 and 40% on their electricity bills, with some saving up to R3,200 per year. The exact saving depends on your household size, hot water usage, and local solar irradiation. Gauteng and Cape Town receive excellent solar resources year-round.

Yes. Solar Ray solar-only systems operate completely independently of the electricity grid. Our insulated tanks retain heat for 24 or more hours, meaning water heated during the day stays hot overnight. Electrical Assist models require power only when the backup element is needed.

As a general guide, you need approximately 30L–75L per person in your household. So a family of four would need a 200L system equivalent (4 × 50L). Our consultants will assess your specific needs and recommend the right system. Contact us for a free assessment.

All Solar Ray systems include a comprehensive 10-year manufacturer's warranty on the inner tank, and a 1-year warranty on all other components. Our after-sales team is available for technical support throughout the warranty period.

Yes. Our geysers are designed to retain heat effectively, so a rainy day will not leave you without hot water. The insulated tank keeps water warm well into the evening even without direct sunlight. If you experience prolonged cloudy or overcast periods, our built-in electrical assist ensures your water always remains warm — so you are never left in the cold regardless of the weather.

An in-roof geyser is a standard electrical geyser that heats water entirely using electricity through an internal heating element. This makes it reliable as long as there is electricity, but expensive to run. An integrated geyser uses energy from the sun and heats water through evacuated tubes, which saves electricity but can be less effective during cloudy weather. A solar geyser with electrical assist is a hybrid system that mainly uses solar energy but automatically switches to an electric element when the water is not hot enough, giving you both energy savings and reliable hot water year-round.

Solar Ray does not install directly. We have a network of vetted, accredited installers across South Africa. Once your quote is confirmed, we connect you with an approved installer in your area who will carry out the installation to our specifications.
