Grid Connect - Frequently Asked Questions

How Does a Grid Connect System Work?
Solar panels or photovoltaic cells are usually installed on the north side your roof (where it has the most exposure) in order to capture energy from the sun, which is then converted to electricity.

By installing a Grid Connect System, your home and/or business will be connected to the main electricity grid that supplies power to your local area. As your system produces electricity, any excess electricity that you do not use is then fed back into the grid. For those times when you need more electricity then what you are producing, your Grid Connect System automatically transfers it back from the grid.

What are Small-scale Technology Certificates (STCs)?
The purchase of a Grid Connect System (Small Generation Unit - SGU) may entitle you to Small-scale Technology Certificates (STCs) if your Grid Connect System is eligible. These certificates can then be sold and transferred to liable entities using a market based online system called the REC Registry, or via the ORER-managed STC Clearing House.

As of 1 January 2012 STCs are replacing Renewable Energy Certificates (RECs) for all eligible Grid Connect Systems. All validated RECs existing at 1 January 2012, or certificates created for installations completed prior to 1 January 2012, will become Large-scale Generation Certificates (LGCs), which must be traded on the LGC market. They cannot be traded through the STC Clearing House.
