The off-grid solar panel system is one of Essens Renewable’s flagship solutions, offering various benefits for users. Unlike on-grid systems, off-grid systems are not directly connected to the PLN grid, but instead rely on batteries. So, how is electricity delivered from the solar modules to the user’s building? Read on for a full explanation of how an off-grid solar panel system works.

What Is an Off-Grid Solar Panel System?

An off-grid system refers to a solar power generation system that operates independently without being connected to the national electricity grid. This system generates electricity from solar modules and delivers it to the user’s building electrical network. Meanwhile, any surplus energy produced is stored in batteries for use at night, when grid electricity is unavailable, or when weather conditions are unfavorable.

Components of an Off-Grid Solar Panel System

An off-grid system relies on batteries to store electricity for later use. An off-grid solar panel system consists of key components that function to capture, store, and distribute solar energy, including solar modules, an inverter, DC/AC protection and disconnection devices (DC isolator/AC breaker), batteries, a charge controller, and energy management devices to maintain system stability and optimize operational performance.

Advantages of an Off-Grid Solar Panel System

An off-grid system operates independently without being connected to the local electricity grid. It generates electricity directly from solar energy, stores it in batteries, and uses it when needed.

As a result, an off-grid system offers the advantage of full control over the electricity supply. Users generate and consume their own electricity, which means their energy usage is not affected by fluctuations in energy prices or monthly utility bills. In addition, off-grid solar panel systems are highly suitable for installation in remote areas.

How Essens Renewable’s Off-Grid Solar Panel System Works

Below is how an off-grid solar panel system converts sunlight into electricity and delivers it to the user’s building:

1. The solar modules absorb sunlight and convert it into electrical energy through the photovoltaic effect.
2. The charge controller regulates the flow of electricity from the solar modules to the batteries, and from the backup generator to the batteries. This component controls the rate of electricity entering or leaving the batteries to prevent overcharging. As a result, battery life can be extended, while the efficiency and safety of the off-grid system are maintained.
3. The regulated electrical energy is then stored in the batteries. This component is essential in an off-grid system because it stores excess energy generated by the solar modules. The electricity stored in the batteries can be used when sunlight is limited, ensuring a continuous electricity supply.
4. The inverter converts direct current (DC) into alternating current (AC).
5. The electricity, now in the form of alternating current, is used directly by the building load.

That is an overview of Essens Renewable’s off-grid solar panel system, from its definition and components to its advantages and how it works to generate and deliver electricity to a building load. 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.

Our customer portfolio spans various sectors, including commercial, industrial, and utility-scale segments.

Components of an On-Grid Solar Panel System

A solar power system generates electricity from sunlight, which is converted into electrical energy through the photovoltaic effect in solar modules. In practice, solar power systems can be installed on rooftops or on the ground, depending on the needs of various industrial sectors.

Therefore, the components of an on-grid solar panel system include solar modules, an inverter, DC/AC protection and disconnection devices (DC isolator/AC breaker), electricity meters (depending on the interconnection scheme), cables, and mounting structures. An on-grid system also allows electricity from the solar power system to be used directly by the load and/or exported to the grid in accordance with applicable regulations.

Advantages of an On-Grid Solar Panel System

As explained earlier, an on-grid system is directly connected to the national electricity grid. As a result, it offers advantages in terms of easier and faster installation, allowing electricity to be used directly by the customer. In addition, on-grid solar panel systems have relatively low maintenance costs because they do not require batteries or other additional supporting components.

How Essens Renewable’s On-Grid Solar Panel System Works

Below is how an on-grid solar panel system converts sunlight into electricity and delivers it to a building:

1. The solar modules absorb sunlight and convert it into electrical energy through the photovoltaic effect.
2. The inverter converts direct current (DC) into alternating current (AC).
3. The AC Combiner, or Solar AC Distribution Panel, installed between the inverter and the load, functions to provide protection against overloads and short-circuit risks.
4. The electricity, now in the form of alternating current, is used directly by the building load.
5. When electricity generation from the solar modules is not sufficient to meet the load demand, or during nighttime, electricity from the PLN grid becomes the main power supply for the building load.
6. The Net Meter records the amount of electricity supplied from the PLN grid to the building load before it is delivered to the building. At the same time, the Energy Meter allows the inverter to read power from the grid and control power production. As a result, no power is exported to the grid.

The electricity generation from the solar modules can also be monitored regularly by users through an application installed on their devices. So far, Essens Renewable’s on-grid solar panel systems have been used in various commercial buildings.

That is an overview of Essens Renewable’s on-grid solar panel system, from its definition and components to its advantages and how it works to generate and distribute electricity to buildings.

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.

Typically, solar energy is harnessed to generate electricity through photovoltaic panels that convert sunlight into electrical energy.

Hydropower

Water has long been used as an energy source due to its abundance. Instead of just being used for daily consumption, recreational areas, or irrigation systems, water can also be harnessed as renewable energy. One way to utilize it is through hydropower plants, where the flow of water moves turbines or windmills to generate electricity.

Wind Energy

The pressure differences between high and low-pressure areas create wind, and its kinetic energy can be used as renewable energy. Wind energy is typically harnessed using wind turbines, where the rotation of the blades drives a generator to produce electricity. Wind energy operates similarly to hydropower, but the movement source comes from the wind.

Geothermal Energy

As the name suggests, geothermal energy comes from the heat stored within the Earth’s layers. To harness geothermal energy, drilling is done until a surface reservoir of heat is reached. The heat produced is then used to move turbines, which generate electricity. Some countries with the largest geothermal resources include Indonesia, New Zealand, and the Philippines, due to their location on the Pacific Ring of Fire.

Bioenergy

Unlike other energy sources, bioenergy comes from organic materials and living organisms like agricultural waste, animal manure, grass, wood, and household waste, also known as biomass. It can be used directly or processed through a series of steps. Examples of bioenergy products include bio-aviation fuel, biogas, bioethanol, biodiesel, and more.

Solar Panels as the Cheapest Clean Energy

A recent study from the University of Surrey found that solar panels are the cheapest source of electricity globally, surpassing other energy sources such as wind, coal, and gas. In countries with abundant sunlight, the cost of producing one unit of solar energy is even less than EUR 1.

The research also concluded that the price drop of lithium-ion batteries by 89% since 2010 has made solar energy storage systems just as cost-efficient as gas power plants.

However, several other factors contribute to solar panels being the cheapest clean energy source, such as:

• Technological and manufacturing industry advancements: Technology improvements have increased the efficiency of converting sunlight into electricity, thus reducing the cost per watt produced. Additionally, advancements in manufacturing have made solar panels cheaper to produce.
• Increased production: The rising global demand for solar energy has driven manufacturers to produce solar components at scale, which in turn reduces material, labor, and production costs.
• Government policies and incentives: Government involvement through subsidies and tax incentives has also boosted solar energy adoption, creating a stable and supportive environment for solar panel installations.

Therefore, the photovoltaic (PV) technology used in solar panels is not only economically affordable but also a key driver of the global shift toward clean and renewable energy.
