With the increasing awareness of the importance of renewable energy, many households in Indonesia are starting to consider the use of solar panel systems. However, before deciding, it is important to understand the differences between Off-Grid and On-Grid systems, as well as the benefits of each. This article will provide a complete guide to help you choose the system that best suits your home’s needs.
Understanding Off-Grid and On-Grid Systems
Off-Grid System
Off-Grid systems are solar panel systems that are not connected to the PLN power grid. The energy produced is stored in batteries and used when needed.
- Independent of the PLN power grid.
- Suitable for remote areas without access to electricity.
- Avoids power outages.
- High initial cost as it requires a storage battery.
- Needs regular maintenance on the battery.
- Possibility of running out of energy during prolonged bad weather.
On-Grid System
On-Grid systems are directly connected to the PLN power grid. The energy generated is used for home needs, allowing excess energy to be sold again to PLN through a net metering mechanism.
- Installation costs are lower as it does not require batteries.
- Dapat reduce electricity bills through net metering.
- Maintenance is simpler than Off-Grid systems.
- Does not work when there is a PLN power outage.
- Depends on PLN’s policy regarding net metering.
Comparison of Off-Grid and On-Grid Systems
| Aspect | Off-Grid | On-Grid |
|---|---|---|
| Connection to Utility | Not connected | Connected |
| Battery Requirement | Yes | No |
| Initial Cost | High | Lower |
| Dependence on Utility | No | Yes |
| Net Metering | Not available | Available |
| Suitable for Areas | Remote, without utility access | Urban, with utility access |

FAQ
Are Off-Grid systems suitable for urban areas?
Off-Grid systems are more suitable for remote areas without access to PLN electricity. However, if you want energy independence, this system can also be applied in urban areas with consideration of cost and energy needs.
How does net metering work in an On-Grid system?
Net metering allows On-Grid system users to sell excess energy generated back to PLN, thereby reducing monthly electricity bills.
Is the Energy Systems Engineering undergraduate program available for scholarships?
Telkom University provides various scholarships for outstanding students. Further information can be accessed through the university’s official website.
