What is An Off Grid Solar System?

An off-grid solar system is a type of solar photovoltaic (PV) system that works independently of an electrical power grid to provide electricity. Also known as a stand-alone solar system, it requires off-grid inverters and battery storage systems to convert and store energy when the need arises. As it is not connected to the power grid, it relies heavily on solar panels as well as the stored electricity in batteries to provide the energy needed to power lights, appliances, and other electrically powered devices.

What Are The Similarities and Differences from Other Solar Systems?


  • How It Generates Power – An off-grid solar system is like any other system because it also generates power by using solar panels to convert sunlight into electricity to turn on lights and run appliances and other machines that need power.
  • Where Solar Panels Are Installed – Like any other solar system, solar panels need to be installed where there is enough sun exposure and needs wiring to transport the power to and from the solar equipment, the building, and the battery.


  • Need for Battery Storage – An off-grid solar system will need battery storage to store surplus electricity to be used when it is needed as it is not connected to an electrical power grid.
  • Lack of Grid-Tie Inverter – It will not need a grid-tie inverter to communicate with the electrical power grid as it is a stand-alone system that is independent from an electricity retailer.

How Do Off-Grid Solar Systems Work?

Off-grid solar systems will start from the sun when the sunlight hits the solar panels to convert it to electricity and then pass it through to the charge controller to charge batteries or power devices. Once batteries are full, electricity will go through to the inverter charger so it can be used to power lights, appliances, and other electrically powered devices. If the batteries are not full, they will keep on charging to be used immediately or for later when the need arises like when the sun goes down or when the solar panels cannot provide enough energy to meet demands.
