Brands Solar On-Grid Systems
Also Known As:
Grid tied, Utility-Interactive, Grid-Intertied or Grid-Direct
Grid-tied systems are the most common type of solar PV system where grid supply is available anytime without major power cuts.
Grid-tied systems are connected to the electrical grid, and allow residents of a building to use solar energy as well as electricity from the grid. Grid-tied systems do not need to produce 100%
of the electricity demand for a home or business. When there is no demand for energy, the solar panels send excess electricity back out into the grid for use elsewhere. When a home or business is using energy, but the solar panels aren't producing enough energy (at night, or on a stormy day), electricity from the grid supplements or replaces electricity from the panels.
Customers need to complete a net metering agreement with TNEB. This agreement allows utility customers to receive credit for the excess energy they generate, typically credited as a kilowatt-hour credit on the next month's bill. Living with a grid-tied solar PV system is no different than living with utility electricity, except that some or all of the electricity you use comes from the sun. Grid-tied systems do not provide protection from power outages.
When the electrical grid fails, grid-tied systems will not continue to operate. This allows utility employees to fix the power lines safely without wasting time identifying solar energy systems that are still feeding electricity into the power lines.
On-Grid system is most suitable for Commercial
and institutional customers where it is mandatory to use renewable energy as one of their power source.
- Solar PV panels (multiple panels make up an array)
- Required electrical safety gear (i.e. fuses, breakers and switches)
- Monitoring system to monitor energy production (optional)
