Sunlight is absorbed by solar panels, which are then converted to direct current (DC). This is then transformed to alternating current (AC) via a solar inverter, which can be used by households or businesses. On-grid solar systems, off-grid solar systems, and hybrid solar systems are the three types of solar energy systems based on energy storage and grid connectivity.

Off-grid Solar Systems

Off-grid solar systems are those that do not connect to the grid and must store excess electricity in batteries. Off-grid systems are often used in rural locations or in areas where the grid connection is unstable.

Off-grid systems are recommended by Freyr Energy for consumers that experience power interruptions of more than 4 hours on a regular basis. Because of the batteries, they require more maintenance and are more expensive than on-grid systems. These systems are self-contained and can power essential loads in places where there is no access to a power grid. These systems, however, necessitate specialized equipment and can be costly to implement.


  • These self-sustaining systems are not reliant on the grid and can operate independently.
  • They produce enough energy to store and utilize at night.
  • These are ideal for isolated locations where grid electricity is unavailable.
  • Your electricity supply will not be affected by grid faults or shutdowns.
