What is hybrid solar system?

A hybrid solar system also known as ‘on-grid solar with battery storage’ generates power in the same way as a typical grid connected solar system but has the ability to store the solar energy generated (click here for more information on how does solar energy works).

Why store the solar energy you generate? A common reason is due to many governments around the world reducing the solar feed-in tariff (money or credit received for feeding solar energy into the grid). This resulted in it becoming less economical to install a traditional grid-connected system as most residential consumers are working during the day and are not home to utilise the solar energy directly. In this situation the solar energy is often fed to the electricity grid for very little return. A hybrid system enables you to store the solar energy generated within a battery bank which gives you the ability to use it when you're home during the evening (when the cost of electricity is typically at peak rate). Since the peak electricity rate in some countries is three to four times the solar feed-in rate a hybrid system can greatly reduce your electricity costs. Many hybrid systems are also able to operate as a backup power system (UPS) to provide limited power during a blackout.

The ability to store and use your solar energy when desired is referred to as self-use or self-consumption. It works in the same way as an off-grid power system but the battery capacity required is far less, usually just enough to cover peak consumption (12 hours or less) as opposed to 3-5 days as with a typical off-grid system.


  • Stores & saves solar or cheaper off-peak energy.

  • Allows use of solar energy during peak times (self-use or load-shifting)

  • Power available during a grid outage or blackout –UPS

  • Enables advanced energy management (ie. peak shaving)

  • Enables energy independence

  • Reduces power consumption


  • Higher cost than on-grid solar. Mainly due to the high cost of batteries.

  • Larger more complex installation requires more room and higher install cost.

  • Battery life of 6-15 years.

  • Can limit how many appliances you can run at the same time (depending on the type of hybrid inverter and its capability)
