Understanding the 3 Types of Solar Panel Systems from Essens Renewable

Solar energy is one of the most efficient and economical renewable energy sources. This clean energy source allows people to harness an unlimited resource, sunlight, and convert it into energy through a completely clean process that produces no emissions.

Interestingly, solar energy can be utilized through several solar panel system configurations that can be tailored to user needs. What are these three types of solar panel systems? Read the full explanation in this article.

Solar Panel System Components

Solar panel systems utilize sunlight, which is then converted into electricity through the photovoltaic effect in solar panel modules. Their implementation may take the form of rooftop solar panel installations or ground-mounted systems, both of which can be adapted for various sectors.

The standard components of a solar panel system include solar panel modules, inverters, DC/AC protection and disconnect devices (DC isolator/AC breaker), electricity meters (depending on the interconnection scheme), cables, and mounting structures. In an on-grid system, electricity generated by the solar power system is used directly by the load and/or exported to the grid in accordance with applicable regulations.

In addition, solar panel systems that are not connected to the national electricity grid (off-grid or hybrid) are also equipped with a set of additional components, such as batteries, charge controllers, and energy management devices to maintain system stability and optimize operations.

3 Types of Solar Panel Systems from Essens Renewable

After understanding the main components of a solar panel system, it is now time to learn about the different types of solar panel systems offered by Essens Renewable.

1. On-Grid System

An on-grid system refers to a solar power system that is directly connected to the national electricity grid. This system generates electricity from solar panel modules and delivers it to the electrical system of the user’s building.

Electricity from the solar panels is prioritized for direct use by the building load during the day. When solar power generation is insufficient, the electricity supply is automatically supplemented by the PLN grid.

Because it is directly connected to the national electricity grid, an on-grid system offers advantages such as easier and faster installation, allowing electricity to be used immediately, as well as lower maintenance costs because it does not require batteries or additional supporting components.

2. Off-Grid System

Unlike an on-grid system, an off-grid system is a solar energy system that operates independently without being connected to the national electricity grid. This system generates electricity from solar panel modules, supplies it to a building’s electrical system, and stores excess energy in batteries for use at night, when grid electricity is unavailable, or when weather conditions are unfavorable.

Therefore, some of the advantages of an off-grid system are that users have full control over their electricity source, usage costs are not affected by energy price fluctuations or monthly bills, and it is highly suitable for installation in remote areas.

3. Hybrid System

A hybrid system refers to a solar energy system that combines connection to the national electricity grid with battery storage, providing greater flexibility than either on-grid or off-grid systems. During the day, solar panels supply the load and may also charge the batteries, while the national grid remains as backup when solar production is insufficient.

In practice, a hybrid system is generally configured in two common operating modes: the battery is prioritized as backup when the national grid goes down, or the battery is used more actively to supply the load after sunset so that the use of solar energy can be extended into the evening.

That concludes the overview of solar energy and solar panels, from their components to the types of solar panel systems offered by Essens Renewable. If you need consultation regarding solar panel installation, Essens Renewable, as a solar EPC company in Indonesia, is ready to help you find the most suitable solution for your needs.
