Over the past couple of years, there has been a steady rise in the number of people switching to solar. It’s not very surprising considering the numerous benefits. There are many deals that help to reduce the overall cost of the system. Read below to find some good Adelaide solar system deals.
Solar Energy: What is it?
Solar energy is derived from the sun. Advances in technology have made it possible that we can now capture and store the sun’s energy and change it into a usable form of energy to power our appliances. Solar energy can be utilised in three ways- passive solar, solar electricity and solar heating.
Electricity from Solar
The general way of switching sunlight to electricity is by making use of photovoltaic cells. Miniature versions of PV cells are usually used in calculators and watches, whilst the larger ones are utilised in Solar power appliances and to provide power to businesses and homes.
How does a PV cell work?
When direct sunlight hits the cell, small particles of light known as photons are absorbed. When the photons have adequate energy, they will free some electrons and push them out of the cell and flow along a circuit that is connected.
This flow of electrons down the length of the circuit creates an electrical current. This movement usually takes place along a path, for example; a piece of wire.
Groups of PV cells arranged together with connected wiring create a solar panel.
These panels do not generate much electricity at night or during a cloudy day. nevertheless you can use batteries to store electricity when the conditions are not ideal and this can help to power your appliances. A number of systems may also be able to store electricity from the national grid.
Photovoltaic solar systems
This type of system is typically made up of an inverter and a PV panel. The inverter converts the generated electricity into a usable form that you can utilize in your business or home. These come in two different kinds.
Systems that are connected to the Grid
A PV system that is joined to the power grid will make sure that you will always have power even when there is no electricity in the system. If you system is grid-connected, you might be able to sell any excess back into the system generator. The benefit of using a grid-connected system is that you will only be charged if there is electricity in the line. During a power outage, grid-connected systems will stop operating.
Solar power has been a quite popular source of clean and renewable source of energy for many properties around South Australia. SA was the first Australian State to introduce a solar feed- in system to promote the use of solar power as an alternative form of energy source. There are currently more than 200,000 solar systems installed in various businesses and houses.
South Australia has brought in a new policy which states that all buildings constructed or refurnished after 2010 use solar systems as their main source of power. Residential buildings that are government –owned are required to have a minimum of 1.5kilowatt solar system installed and all other buildings at least a 5 kilowatt solar system.
Stand-alone systems
PV systems that are not connected to the power grid are known as Stand-alone systems. They use batteries which store electricity produced during the day to be used at night. These systems work best in areas with low demand for electricity and help to power remote communities where a connection to the main power grid is not accessible. When you opt for this type of system, it is important to check that the panels can produce enough power and of the right size.
