Solar Panels

Solar Panels

Solar Panels can be divided into two different types. You have the Photovoltaic Solar Panels and then you have your Solar thermal collector. Both use the energy from the sun and convert it to power or hot water.

Photovoltaic solar panels & solar thermal collectors can be used independently of each other or in combination. They both serve a different purpose.

Photovoltaic solar panels.

Photovoltaic solar panels collect light from the sun and converts this light into usable electricity. These solar panels can be connected to a battery system to store electricity for use when the sun is not shining. You can have grid tied systems which means you are still connected to the main electricity grid. Off grid systems are stand alone systems where one is not connected to the main electricity grid to have uninterrupted power a battery backup system is required.

Solar thermal collectors.

Solar thermal collectors convert the solar energy received from the sun into hot water or hot air. These solar panels are commonly used in South Africa for heating pools, heating water for use in showers and baths. Considering hot water requirements for a modern household are a major contributor to electricity bills. Investing in solar thermal collectors is a worthwhile investment which should pay for itself. They are also a great solution for the many areas in South Africa which have not been electrified. It will provide cheap hot water for our daily needs.

Solar thermal collectors are more commonly installed than Photovoltaic solar panels due to the technology being simpler and more affordable. If electricity keep rising then we might see more installations of photovoltaic solar panels.
