How does grid feed-in work?

Grid feed-in is a process in which the electricity generated is fed directly from the solar module and the appropriate inverter into the public power grid. Ideally, the inverter is installed near the solar modules and connected to the solar module using the solar connector. Regardless of the size of the system, it is necessary to register the solar system with the market master data register in accordance with legal requirements.

The complete system includes:

• 8x Luxen Solar 450W Bifacial Solar Module TopCon Luxneri Series N5 Full Black
• 1x Growatt MIC 2500TL-X 2.5kW string inverter PV 2500W 1-phase
• 1x Growatt SPM-E electricity meter 1-phase 100A smart meter

LECO N-TOPCon cell technology

Advanced TOPCon (Tunnel Oxide Passivated Contact) technology is a further development of PERC technology and aims to increase the efficiency of solar cells. This technology is complemented by Low Efficiency Cell Optimization (LECO), which aims to further optimize the overall performance of the cells, especially under less than ideal lighting conditions. During the manufacture of the solar modules, an ultra-thin oxide layer is applied, followed by a conductive layer, resulting in what is known as a passivated contact. This design not only improves the performance of the solar cells in low light conditions, but also contributes to higher annual energy production.

In addition, the combination of TOPCon and bifacial technology enables even greater power efficiency, as the cells are able to absorb 15% more reflected light. These synergistic effects lead to a significant increase in energy yield and make the solar cells an outstanding choice for modern photovoltaic applications.

Why use a string inverter: The performance of solar modules varies depending on temperature, irradiation, and shading, which can lead to mismatching losses. These losses occur when the performance of one panel in a string is lower than the others, resulting in lower power production for the entire string. A string inverter can reduce these losses.
Maximum Power Point Tracking: Maximum Power Point Tracking technology generates the best possible yield from a solar system. The MPPT of the MIC inverter determines the optimal ratio between voltage and current throughout the day, depending on the solar radiation and the temperature of the solar modules. The large MPPT voltage range allows a large number of solar modules to be connected, enabling efficient energy yield. The advantage of this is most noticeable when the sky is partially overcast and the light intensity is constantly changing.
Flexible and easy installation: Thanks to its compact dimensions and low weight, the inverter is quick and easy to install and connect. The integrated MC4 connections also allow the solar supply to be connected to the inverter in a matter of moments. The numerous protective functions ensure safe and smooth operation of the solar system.
