Photovoltaic installations: On-Grid vs. Off-Grid
Photovoltaics are the modern way to harvest clean energy from the sun, but choosing the right system for your needs is crucial. Wondering whether to choose an on-grid or off-grid installation? We have put together a detailed comparison of both solutions to help you make an informed decision.
What is the difference between On-Grid and Off-Grid systems?
On-Grid
The on-grid system works with the public electricity grid. The energy produced is consumed on an ongoing basis and any surplus is sent to the grid so that it can be ‘picked up’ at a later date. This is a popular solution in homes and businesses.
Off-Grid
An off-grid system operates completely independently of the power grid. It requires energy storage to store surplus energy for later. It is an ideal solution for locations remote from the infrastructure or for people who want to be fully self-sufficient.
| Feature | On-Grid | Off-Grid |
|---|---|---|
| Connection to the network | Yes - the system requires cooperation with the public electricity grid. | No - the system operates autonomously, without the need for a network connection. |
| Energy storage | Not required - surplus energy goes into the grid and can be collected at a later date. | Required - energy is stored in energy storage (e.g. lithium-ion batteries). |
| Network dependency | Dependent - in the event of power cuts, the installation does not work. | Self-contained - ideal for locations without access to the power grid. |
| Cost of installation | Lower - no need to invest in energy storage. | Higher - the need to purchase energy storage increases the initial cost. |
| Effectiveness | Very high - the system makes maximum use of the energy produced. | It depends on the capacity of the energy storage facilities and current power consumption. |
| Application | Homes, businesses, buildings in cities where network access is standard. | Sites cut off from the grid, holiday homes, farms in hard-to-reach locations. |
When to choose an On-Grid system?
- When you have access to the public electricity grid.
- When you want to reduce your electricity bill and make the system easy to use.
- When you do not want to invest in energy storage.
When to choose an Off-Grid system?
- When you want to be completely independent of energy suppliers.
- If your home or business is located in a place without access to the power grid.
- When you want protection against power cuts.
