The Basics – How Solar Power Works
- Solar panels convert sunlight into DC ( direct current) electricity.
- Solar inverters convert the DC electricity produced by the solar power systems into AC electricity ready for use. The solar inverter is connected through the electricity panel for all grid connected solar systems.
- The electricity panel provides the common link between the solar inverter, household electricity and the electricity grid (your traditional power supplier – Origin, AGL etc.).
6 Benefits of Solar Power Systems
- Reducing your carbon footprint by using environmentally friendly solar energy.
- Reducing the quarterly cost of your electricity accounts.
- Taking advantage of government feed-in tariff incentives.
- The ability to sell your excess power back to the power grid.
- Adds capital value to your home.
- Doing your part to help reduce our dependency on fossil fuels and reduce your carbon footprint.
What is solar energy? Solar energy is energy which is created from sunlight, or heat from the sun.
Solar power is captured when energy from the sun is converted into electricity using photovoltaic cells and used to heat air, water or other fluids.
There are currently two main types of solar energy technologies:
- Thermal Solar Power: these systems convert sunlight into thermal energy (heat).
Most solar thermal systems use solar energy for space heating or to heat water (such as in a solar hot water system). However this heat energy can be used to drive refrigeration and provide solar based cooling.
The heat can also be used to make steam, which can then be used to generate electricity using steam turbines. It is considered more efficient to build solar thermal electricity generators at a large scale, typically in the tens to hundreds of megawatts.
- Photovoltaic Solar Power (PV): the conversion of sunlight directly into electricity using photovoltaic cells.PV systems can be installed on rooftops, integrated into building designs and vehicles, or scaled up to megawatt scale power plants.
Definition of “photovoltaic”: Photo means “light” and photons are energy particles coming from sunlight; voltaic means producing a voltage or volts. Abbreviation = PV
How is solar energy used in Australia?
Australia has the highest average solar radiation per square metre of any continent in the entire world.
More than 2 million Australian households now have solar hot water systems or solar rooftop systems.
Megawatt-scale solar electricity generation systems is still at an early stage of development in Australia.
Solar power is clean green electricity that is either created from sunlight or from heat from the sun.
Having solar electricity in your home usually means setting up a solar photovoltaic system on your roof.
Solar energy is a renewable source of energy that is sustainable and totally inexhaustible, unlike all fossil fuels (like coal and natural gas) which are finite. It is also a non-polluting source of energy and it does not emit any greenhouse gases when producing electricity.
Solar electricity can in some cases supply households entire energy needs. As electricity storage improves this will become more widely true.
How do solar panels work?
Solar panels use what’s known as the photovoltaic effect to generate power.
This is the process by which light is converted to energy at the atomic level.
When light hits a solar cell, electrons are knocked loose from a solar cell’s semiconductor material atoms. Positive and negative electrical conductors associated with each solar cell form a circuit that captures this energy in the form of an electrical current.
Grid connected solar power systems
PV systems generate energy from sunlight during the day.
This energy goes into a grid-connected inverter which converts the DC current into AC current.
This solar generated electricity can then power all the appliances in your home, such as cooking appliances, phones, computers, lights, radios, etc.
Power can be drawn directly from the solar inverter and any leftover electricity can then be fed back into the grid. At night when your solar power system isn’t producing any electricity you draw power from the grid as you would normally do.
Can you make money by selling your excess power with Solar Panels?
If you need more electricity than your solar panels produce, the additional electricity will be taken from the main distribution grid.
On the other hand, if you produce more energy than you use, then you may receive credits to offset against your bill.
Some electricity retailers offer net billing, meaning your grid power supplier buys the excess power you produce for the same retail price they charge you.
Town and Country Solar will manage your dealings with your grid supplier to ensure you benefit from whatever benefits you are entitled to.
No Battery Back Up Required
Grid connect solar power systems eliminate the need for a battery back-up. (where a grid supplier is available this is the standard configuration).
At night or during cloudy weather you can draw electricity directly from the grid.
To install a grid connect solar PV system, you need a north-facing roof with sufficient roof space. With a large enough system getting sufficient sunlight and generating solar power efficiently to meet or exceed your electricity usage.
