What is the difference between an on-grid solar system and an off-grid / hybrid solar system?

On Grid Solar

Pros

  • Simple design, and low maintenance
  • It can be easily integrated for net-metering.
  • All appliances can work on it, since wiring does not need to change.

Cons

  • Only works when grid power (reference line) available. In case of power cuts, solar electricity cannot be used, since it depends on a reference voltage from grid power.

Best used for

  • An on-grid system is ideal when you would like to lower your electricity bills, and do not need power backup.

 

Off-Grid or Hybrid Solar

Pros

  • In areas with unreliable power, people often have batteries and an inverter system for more steady electricity. Solar power can be added to charge batteries faster when grid-power is present, and to power appliances when it is not.

Cons

  • Wiring for the solar system is separate, so typically only a few appliances are hooked up to use that electricity.
  • Batteries require maintenance and need to be changed every three or four years. Maintenance-free batteries are typically more expensive and so, less popular.

Best used for

  • An off-grid system is best suited if you have unreliable electricity and are looking to decrease disruption to your life due to that.
