Solar Photovoltaic

When light energy is absorbed by a material known as a semiconductor, an electrical charge is created, this property of the material is known as the photoelectric effect. Silicon is the most common semiconductor used by PV cell manufacturers.

Stand alone PV systems are not connected to the grid. Stand alone systems are set up so that you use the electricity produced by the PV system directly. In order to take full advantage of the electricity produced, it needs to be stored. For this reason, a standalone system will commonly include battery storage.

Solar Thermal

Solar water heaters use the solar energy from the sun to generate heat (not electricity) which can then be used to heat water for showering, space heating, industrial processes or even solar cooling.

Solar energy is the primary energy source for our planet as it is responsible for providing energy for plant growth (Photosynthesis) and providing the warmth that makes our planet habitable.
