The WA State Government is introducing emergency solar management requirements for new and upgraded residential rooftop solar systems with an inverter capacity of 5kVA or less that are installed or upgraded on or after 14 February 2022.Find out more
Generate your own renewable electricity to use at home while the sun is shining – or invest in a battery to store excess electricity generated.
Living in one of the world’s sunniest locations has its benefits. With solar panels on your rooftop, you can harness the power of that WA sunshine to generate electricity for your home.
The amount you could save on your electricity costs will depend on a number of factors including how and when you use electricity, and the size and quality of your solar PV system.
Solar panels catch the sun’s rays and transform the sun’s energy into electricity through your inverter.
Electrons vibrate within the photovoltaic (PV) cells in the panels, which generates electricity.Learn more about solar panels
If you have a battery installed, you can store excess electricity generated to use when the sun goes down and your system stops generating.Learn more about batteries
An export limit refers to the maximum amount of solar energy generated by a rooftop solar PV system, in excess to personal consumption, that is permitted to be exported to, or feed back into, the electricity grid. The purpose of export limiting is to help ensure that the grid remains stable and safe.
For the solar PV system to be export limited, at installation a sensor is attached to the inverter that determines the amount of current being sent to the grid (an export limiter).
The inverter converts solar energy into electricity. This solar generated electricity offsets consumption at the property first at the time of generation and then anything in excess is exported to the grid. The export limiter controls the amount that can be exported to the grid.
The offset of solar generated electricity against your personal consumption will help to reduce your electricity costs as you are not drawing electricity directly from the grid.
Export limits are set in accordance with Western Power’s Basic Embedded Generator Connection Technical Requirements.
An application to install or connect a solar PV system that cannot meet ESM requirements and is required to be subject to an export limit cannot be completed online. To apply, please complete the Distributed Energy Systems Application for renewable energy system with an inverter capacity of up to 30kW form.
No. The processes of manufacturing, transporting and installing solar panels and solar technology involves creating carbon emissions – but solar is definitely a cleaner, greener form of energy, especially when compared with other ways electricity can be generated.
