Types of solar system installation based on power connection
GRID-TIE PV SOLAR SYSTEM Grid-tied or grid connected solar is a solar electricity system without batteries. Your home is hooked up to both the national grid and your solar electricity system. You can install a solar electricity system of any size and you will only ever be billed if your power consumption is in excess of the amount you are generating.
HYBRID PV SOLAR AND BACKUP SYSTEM This system comprises solar power with battery backup and all excess power generated by the solar panels is returned to the grid. Smart inverters can be programmed to use battery power during municipality peak tariff times.
OFF-GRID PV SOLAR SYSTEM For situations where mains power is not available, or the client wishes to become completely independent of the grid. All power is generated by the solar panels; a battery bank stores excess power for use at night or when the sun is not shining.
