The following illustration and narrative explains how your solar power system works:
- The solar electric panels, or modules, are usually fitted to the roof. The number of modules will depend on the nominal size of your system and, collectively, they are known as the solar array. The solar array converts sunlight into direct current (DC) electricity.
- The DC electricity is fed to the inverter which is normally accessible from ground level. The inverter converts the DC electricity to alternating current (AC) electricity which is compatible with the electricity supplied to your house from the grid. Some inverters have a digital readout so you can monitor information like how much solar electricity is produced, etc. Refer to the separate inverter Owner’s Manual for more information.
- Depending on local regulations, your solar electricity system will be connected to the grid via a net metering system. With net metering, if electricity is being used in the house during the day, some or all of the solar electricity will be used up immediately. Any excess will be fed through the meter into the electricity grid.
- The standard meter located in your meter box will need to be replaced with a bi-directional meter which will measure how much solar electricity is exported from your solar system into the electrical grid as well as the electricity you import from the grid. This new meter will be installed by your chosen electricity provider so you need to contact them and make the necessary arrangements. There may be a cost involved for the new meter. Once it is installed, your electricity provider will buy your solar generated electricity at the applicable ‘feed in’ tariff.
- When the solar cells are not producing power, for example at night, your electricity is supplied by the mains power grid as usual. Your electricity provider will then charge the usual rate for the power used.
Use the following table to help determine your system size.
|Units of electricity generated
|No of Panels||Roof Area
|Approximate Greenhouse Gas Reduction|
1. Output based on the average Peak Sun Hours in Bunbury, Western Australia, with optimal installation. Performance varies by location.
2. Savings based on an average daily use of 17 Units per day. Check your recent power bills for your average daily use.
