What are on grid systems and what are their components? The on grid system is considered one of the types of solar systems, and in our article we will learn about an important topic in which it talks about on grid systems and their components, and when are they installed?

What are on grid systems?

They are systems that can be connected to the public electricity network, and do not require a means of storing electrical energy such as electric batteries. They are suitable for places where the public electricity network is available around the clock. Otherwise, the system is not suitable if there is a recurring outage in public electricity.

These systems are distinguished from isolated systems in their ease of establishment and lack of system components, in addition to the low cost of establishing them compared to systems separated from the network.

Some electricity companies stipulate that the installation of solar panels up to a capacity they specify requires that all of the energy be exported to the electricity network, and thus you will only benefit from reducing the value of the monthly bill by 50% or otherwise depending on the company policy in your country.

It can be said that the idea of ​​these systems revolves around the beneficial exchange between the electricity company and the owner of the solar system.

Components of on grid systems

The systems connected to the electricity network consist of the following basic elements:

• Solar Panels.
• Inverter.
• Electrical energy metering system (electric meter for on-grid solar energy systems).
• Electrical protections.

Since the system is connected to the local network and electrical energy, whether produced by the solar system or consumed by the local network, has a cost, therefore there must be a measuring system for this electrical energy, which is the electronic meter.

Important note: If the electricity network is cut off from the inverter, the system will stop and will not work until the electricity is restored again.

Benefits of installing an on grid system

The main benefit of the On Grid system lies in investment, by selling the electrical energy produced from solar panels to the General Electricity Company. Therefore, the system is useful for those who consume large amounts of electrical energy and pay high costs every month. Therefore, the On Grid system is the ideal solution for them to reduce the value of the bill amount. To half or more according to the policies of the General Electricity Company.
