On-grid systems are defined as solar energy systems connected to the grid.
✔️ You pay no electricity bill.
✔️ You can generate income by selling the excess electricity you generate.
✔️ You are not affected by electricity price increases.
✔️ Since the electricity generated is used immediately or given to the system, there are no additional costs such as batteries.
✔️ They are sustainable systems that do not require ongoing maintenance.
✔️ There are only initial investment costs.
✔️ Energy transmission losses are minimal.
✔️ The system can be easily designed according to the desired capacity.
On-grid systems are defined as grid-connected solar energy systems. This system, which is connected to the central power grid and where the electricity produced from solar panels is used as soon as it is produced, and where, when the production from solar panels does not meet the need, the need is met by the grid, is the most widely used system today. In the on-grid system, there is no additional intermediate storage (battery-battery, etc.) and the energy produced in excess of what is needed from solar panels is immediately transferred to the grid.
In this system, solar photovoltaic panels generate direct current (DC) by stimulating the electrons in the silicon cells on them using the sun’s radiation. The generated electricity is converted to single-phase or three-phase alternating current by specially designed inverters and connected to the grid with a bi-directional electricity meter. The energy supplied to and consumed by the bi-directional electricity meter is recorded. Thus, at the end of each month, the energy produced and consumed by your home or workplace is recorded and compensation is taken care of with the company that supplies you with energy. If the energy you produce with the solar system is more than the energy you consume during the month, the consumer is paid.
On-grid systems can be installed with high power (GES) as well as lower power to meet the needs of homes. This system basically consists of 4 components;
Solar panels, the most fundamental component of solar systems, convert the sunlight (photon) falling on them into direct current electrical energy by means of solar cells made of semiconducting silicon material. Solar panels are calculated according to the daily energy consumption and the size of the area of application. According to the result of the calculation, suitable Arçelik monocrystalline panels with high strength and efficiency are selected.
Inverters, in the simplest definition, are electronic devices that convert DC (linear current) electrical energy into AC (alternating current) electrical energy thanks to the circuits inside. Inverters on the power grid convert direct current into single-phase or three-phase alternating current, depending on the area of application. These inverters work together with the current from the sun and the current from the grid. Thus, the current flow in the solar panel is supported by the grid.
At the points of contact between the solar power system and the grid, the protection of the system is provided by fuse, leakage current and surge protection. This ensures that the protection and control of electricity and thus the health of consumers is not compromised.
Bidirectional electricity meter;
Bidirectional electricity meters, as the name implies, provide bidirectional transmission of electricity. In short, it transmits electricity coming from the grid to the home like one-way meters, while transmitting electricity generated from solar or another source to the grid. With smart two-way meters, you can track electricity generated and consumed through the digital display on the meter.
