OFF GRID POWER SYSTEMS: Be completely disconnected from the grid
Off Grid Solar
What is an off grid solar system? An off grid solar system is a stand-alone system that is not connected to the electricity grid. Off grid solar systems are expensive and are generally only a viable option when the cost to connect a property to the electricity network is inordinate. If you happen to have a grid connection you are definitely better off purchasing a solar system.
Off Grid Solar System Prices
The price of an off grid solar system varies depending on how much power you use, your location and the amount of backup power you have.
Off Grid Solar System Sizes
The key to a successful off grid installation is ensuring you have enough panels and batteries to power your daily electricity consumption and not leave you in the dark.
Days of Autonomy
If you don’t have any back-up power in the form of a generator, you will want to ensure you have enough solar storage to get you through a few days. If your solar panels do not generate any solar energy over those days, you will still have power. The amount of storage and days of autonomy depend entirely on your location.
Back-up Power
It is common for off-grid solar systems to have back-up power in the form of a diesel generator or wind turbine. Back-up power is beneficial and can mitigate the 100% reliance on battery storage.
How does Off-Grid Solar Work?
Off grid solar works by generating electricity from solar panels and utilising that energy to charge a solar battery using a charge controller. Inverters convert the DC (direct current) to AC (alternate current) so that it can power your home or business appliances. The excess solar power charged your solar battery so that you can use the electricity at night or during times your system is not generating power.
Components Included In an Off Grid Solar System
For off-grid solar to work effectively, the average home will require the following components
- Solar Panels
- Solar Battery
- Solar Inverter
- Solar Charge Controller
- Alternative energy resource (optional)
Solar Panels
Solar panels are a necessity for a stand-alone system. The number of panels you will need depends on your daily electricity usage.
Solar Batteries
Solar batteries are also necessary as they allow your home to continue to run after the sun goes down. During the day, your solar battery will charge as your solar panels will generate excess electricity.
Solar Inverter
Solar inverters convert the direct current collected by your solar panels into the alternating current which is required to run your household appliances and electronics.
Solar Charge Controller
Solar charge controllers are vital to your batteries health. The controller regulates the voltage and current that your solar battery receives.
