Other types of Solar Water Heating
Solar Hot Water
These systems have been available and have provided homes with water heating for many years now.
There are currently two main types of solar hot water systems.
The commonly recognised flat plate solar collector, which is made up of a number of copper pipes running through a glass covered collector which is usually connected to a water storage tank on the roof. The hot water can then thermo siphon itself through the tank and heat the water.
Evacuated Tube Collectors
Evacuated tube solar collectors use a glass tube inside a vacuum which has copper pipes running through the centre. These pipes are joined to a common manifold which is connected to a slow flow circulation pump that then pumps water to a storage tank below.
WIND POWER EXPLAINED
Wind turbines operate on a simple principle.
The energy in the wind turns two, three or propeller-like blades around a rotor.
The rotor is connected to the main shaft, which spins a generator to create electricity.
Wind turbines are mounted on a tower to capture the most energy at 4 meters or more above ground so they can take advantage of faster and less turbulent wind.
Wind turbines produce electricity which when feed to the solar controller, is added to the electrical energy produced by the solar panels to power the home or building.
Due to the visual and noise pollution of wind turbines they are generally only used in Rural areas.
