FAQ - Frequently asked questions
Our target group is electrical contractors, solar specialists, solar installers and similar companies. Unfortunately, we are unable to supply private customers, but we are happy to arrange a specialist retail partner.
No, because Tier 1 is not necessarily a sign of quality. You can read about it here:

Thanks to our large warehouse of currently 18,000 m², we can deliver modules in stock within a very short time through our shipping partners.
Thanks to our large warehouse of currently 18,000 m², we can deliver modules in stock within a very short time through our forwarding partners.
We offer a 20-year guarantee on the product and 25 years on the performance for mono-facial modules and a 20-year guarantee on the product and 30 years on the performance for bifacial modules.
Modules with tempered glass on the front and back. Such modules can also generate electricity by shining light on the back of the module.
Our modules have a glass thickness of 3.2 mm (monofacial modules) or two glasses with a thickness of 2.0 mm for the bifacial modules, while our competitors usually only use glasses with a thickness of 1.6 mm. At Becker Tech you get more for your money!
Perc cells are a type of solar cell based on perovskite materials. They are a promising alternative to conventional silicon solar cells due to their high efficiency and low manufacturing costs. Perc stands for "Passivated Emitter and Rear Cell" and refers to the special structure of the cells in which the emitter and the rear of the cell are passivated to reduce losses and improve performance. These cells have a high efficiency and are promising for photovoltaic applications as well as for a wide range of optoelectronic applications.
N-type solar modules are a type of photovoltaic module that uses N-type semiconductor materials to convert sunlight into electricity. These modules are made of silicon wafers with a special crystal structure that enables higher efficiency and better performance compared to other types of solar modules. N-type solar modules are characterized by high performance, greater temperature tolerance and less degradation over time.
Degradation of solar modules is the loss of performance of solar modules over time. Degradation can be caused by various factors, including thermal, mechanical and electrical influences. The rate of degradation can vary depending on the type of solar cell and the materials used. The term "power degradation" is often used to describe the decrease in performance of solar modules.
The bypass diode is a special diode used in solar modules to regulate the current flow within the module. It is connected in parallel to the solar cells and serves to protect the cells from the negative effects of shadowing, shading and partial failures. The bypass diode bypasses the affected cells and directs the current past them to ensure an uninterrupted current flow.
The module efficiency of solar modules is expressed as a percentage and is defined as the ratio of the maximum electrical output power of the solar module to the irradiated solar energy. It is usually measured under standardized test conditions, which provide for an irradiance of 1000 watts per square meter and a cell temperature of 25 degrees Celsius.
Half-cell modules are an advanced technology in the field of solar modules that are characterized by a special cell architecture. In contrast to conventional solar cells, half-cell modules consist of two separate cells connected in series. This division of the cell into two parts improves the current flow and electrical output.
A monocrystalline solar cell is a photovoltaic component that consists of a single crystal. This type of solar cell is characterized by high efficiency and a high degree of effectiveness. They are often used in solar modules to generate electricity from solar energy.
Off grid refers to a condition or situation in which the solar panels are not connected to the public grid. In this case, the solar panels serve as the sole source of electricity and provide an independent power supply for various applications. Off-grid systems are often used in remote areas where there is no access to a stable power grid. They offer a sustainable and environmentally friendly alternative to conventional power generation.
The "On Grid" connection of solar modules refers to the connection of solar systems to the public power grid. In this case, the solar energy generated is fed into the grid and the power supply to consumers is ensured by both the solar system and the grid. This differs from "off-grid" systems, in which solar systems are operated independently of the public grid and the power supply is based solely on solar energy.
The performance ratio (PR) is a key figure for evaluating the efficiency of solar modules. It expresses the ratio between the energy actually generated by a solar module and the maximum possible energy due to the irradiation situation. The PR is given as a percentage and serves as a measure of the efficiency and quality of a PV system.
