 Grid Connect Systems
Grid connect solar photovoltaic systems are the most cost effective way of solar powering your home. They can be scaled to meet anything from a portion of a household's power requirements to the power requirements of large household.
In a grid connected solar photovoltaic system, the solar panels generate low voltage DC power which is then fed through a grid connect inverter which converts it into grid compatible 240V AC power which feeds into your switchboard.
During the day, the solar electricity supplies any power requirements of the home with any shortage drawn in from the grid. If the solar array is producing more power than the home is using, then the excess solar electricity is fed out through the switchboard into the grid, running your meter backwards. At night when there is no solar power being produced, electricity is drawn in from the grid.The Solar Bonus Scheme will credit eligible participating customers with a gross feed-in tariff rate of 60 cents per kilowatt hour for all the electricity that their eligible solar photvoltaic system generates.
The end user does not need to do anything to make the system work and will notice no change at all in the way their electricity operates. The only difference is some panels on the roof, an inverter next to the switchboard and a reduced electricity bill.
You may wish to choose a system which covers a certain percentage of your electricity based on budget, available roof space or a range of other factors. The amount of electricity you use on average is shown on your electricity bill in kilowatt hours (kWh) per day.
Diagram of Photovoltaic Grid Connect System
- Sunlight consists of particles called photons, which are absorbed by the solar panels. The photoelectric effect causes the flow of free electrons – DC (Direct Current).
- The DC (Direct Current) from the solar panels is fed to the inverter which changes it to 240V AC (Alternate Current).
- Appliances in your house / business use solar electricity direct from the inverter
- Your electricity meter will separately record the electricity energy drawn from the grid and the excess solar electricity flows through a meter back to the grid.The Solar Bonus Scheme will credit eligible participating customers with a gross feed-in tariff rate of 60 cents per kilowatt hour for all the electricity that their eligible solar photvoltaic system generates.
- Electricity also flows back from the grid through the meter as per normal
