Solar power generation system home export

What is solar export control?

In essence, solar export control refers to the amount of solar power you can send to the grid from a grid-connected solar installation. These limits can apply to any size of solar installation, from utility-scale projects to solar panels on private residences. Suppose a solar plant produces more electricity than can be supplied to the grid.

Can a home export a lot of solar power?

The Bad: Most homes can’t export as much power as in Good locations, but export limiting can be used to install larger solar systems. And The Ugly: Here, most homes are limited to 5 kilowatts of solar inverter capacity or less, and export limiting is usually not permitted. The information below assumes the property is on the main grid.

Can a solar inverter be exported to Australia?

Many Australian homes are not allowed to export more than 5 kW to the grid. If they want a big solar system with an inverter larger than 5 kW, they must ‘export limit’ the inverter. Here’s what that means. Rooftop solar works by turning sunlight into electric power.

Can a home export a solar inverter to zero?

The Ugly: Homes can be prohibited from exporting any power to the grid at all. In this case, export limiting an inverter to zero can allow the installation of a solar system that helps meet daytime electricity consumption, but it won’t receive any feed-in tariff at all.

What is a solar export limit?

The solar export limit refers to the maximum quantity of energy that your solar system may transmit into the grid, as set by your local power provider. You cannot transmit or sell electricity to the grid if you exceed the limit, which is around 5 kW. Many homes are prohibited from exporting more than 5 kilowatts (kW) of solar energy into the grid.

Is exporting surplus solar power a good idea?

Exporting surplus solar power is good because it reduces fossil fuel generation and pays you a feed-in tariff that reduces electricity bills. It’s becoming common for solar inverters to be export limited, so the maximum amount of power they send into the grid is less than they’re capable of providing. This is done for three main reasons:
