Types of solar systems

On-grid, off-grid and hybrid solar

There are three main types of solar energy systems:

On-grid

An on-grid (or grid-tied or grid-connected) solar power system generates electricity from light via solar panels mounted on your roof.  A solar inverter converts the solar DC power to AC power that your appliances can use.

If you don’t use all the electricity generated by your solar panels, the surplus is exported to the grid and credited against your power bill.  

If you need more electricity than your system generates, this is supplied by your grid connection. The process is fully automated and your system’s energy meter will show you exactly how much electricity you are generating and using.

Grid-connected PV systems are most economical when you can use most or all of the power they generate. This might mean being at home during the day, setting power-hungry appliances on a timer, or charging your electric car during the day.

Off-grid

Off-grid solar gives you complete independence from the power grid and means there are no power bills to pay. It’s ideal for remote sites where it might be too expensive or difficult to connect to the grid, or for people who want to be completely self-sufficient.

This system relies on battery storage and an inverter/charger. The power generated by your solar panels supplies the inverter/charger, which maintains and charges the storage batteries while also converting the energy to AC power. The stored energy can be used by your appliances, for lighting, and anywhere you would normally use electricity from the grid.

Hybrid

A hybrid solar system combines the best of both worlds – the convenience of an on-grid system, with the peace of mind of a battery backup.

Instead of surplus power being exported back to the grid, it is stored in a battery in your home for use when you need it. 

But your system is still connected to the grid, which gives you back-up on low solar production days. No more power outages at your place!
