You can use solar power to run outdoor lights; replace security, poolside and garden lights with solar powered lights and save electricity. They are long lasting and will last through all weather conditions.
Solar water heating is also a great alternative to normal electricity-intensive geysers.
There are two types of geysers – direct systems that [...]
As with a conventional geyser, the hot water storage container in a solar geyser is thermally insulated to retain heat.
Solar geysers are usually larger than electric geysers and better insulated. This allows you to maximise your solar gains.
Solar geysers can be linked to existing geysers or can completely replace them. The system can be installed [...]
In this sunny country, solar energy is an abundant source of renewable energy, making it an obvious choice when seeking alternative sources of energy.
Solar water heating & how a Solar Geyser works
Solar geysers are built on two basic principles of physics: dark coloured objects absorb heat, and hot water rises.
Unlike other systems that can be [...]
