Different types of SAA accreditation
Grid Connected Battery System (GCBS)
This is a form of energy storage that is connected to the grid. It can be charged by a solar system or other energy source and can supply loads when the sun has gone down, and energy from the solar system is no longer available.
Grid-connected Photovoltaic (PV) System
This is an energy generation system that is connected to the grid. Photovoltaic (PV) modules (Solar panels) generate DC electricity that is turned into AC electricity using an inverter. The energy produced is used to power homes with any surplus energy sent back to the grid.
Stand-alone Power System (SPS)
SPS is an independent energy generation and storage system that has no connection to the grid. The system combines solar panels, energy storage and a backup energy source. It functions independently of the grid, providing power to homes or other types of buildings.
NOTE: A system which provides some level of energy independent from the grid but is still connected to the grid as a backup source is not deemed an SPS for the purpose of accreditation.
