FAQ

Off-grid and on-grid solar energy systems differ in how they are connected to the electrical grid and how they use or store the energy produced.
On-grid systems are directly connected to the electrical grid. This means that excess solar energy produced can be fed back into the grid, while any deficit can be compensated with energy from the grid. Off-grid systems are not connected to the electrical grid. They operate independently and usually rely on batteries to store excess energy for use when the sun is not available.

On-grid systems offer stability because they can rely on the electrical grid when more energy is needed than produced or when solar energy is insufficient. Off-grid systems are self-sustaining but are subject to changes in weather conditions and require adequately sized batteries to ensure continuous energy supply when there is no sunlight.

On-grid systems typically have lower initial costs because they do not require expensive batteries for energy storage. Off-grid systems have higher initial costs due to the need for energy storage batteries, but they can save money in the long run as owners do not pay electricity bills.

On-grid systems offer greater flexibility because owners can use the electrical grid as needed and are not limited by battery capacity.
Off-grid systems are less flexible as they rely solely on energy production from solar panels and storage in batteries. However, in some cases, an off-grid system is the only option available (for remote locations, rural areas without electrical grid access, etc.).
