The 1KOMMA5° Full-Black Solar Panel

A photovoltaic module consists of solar cells that are usually connected in rows and convert sunlight into electricity. Behind the solar cells is a plastic film or glass to protect the module from moisture and dust. On the top of the module, a resilient glass pane ensures that the module can withstand wind, rain and snow for decades. A stable frame made of aluminium encloses the entire module.

The most important component of the module is the cell. Without it, no electricity is generated, and its quality and structure are decisive for the yield. The cell consists of a so-called wafer - a wafer-thin disc cut from crystalline polysilicon (ingots). The polysilicon, in turn, consists of high-purity silicon, which is extracted in an energy-intensive process, usually from quartz sand.

At the moment, we still produce in Asia. We rely on the highest quality and social standards. Our production sites are certified by TÜV Nord according to the ESG standard SA8000. Production is carried out using automated production processes and high-quality materials and meets the Tier 1 criteria of Bloomberg New Energy Finance (BNEF).

In addition, we already invest in a clean and local supply chain and source the critical raw material polysilicon from Germany. By 2025, we want to establish our own production line with a capacity of 5 GW per year in Germany or another European country.

The supply chain for the 1KOMMA5° solar panel is designed ethically and sustainably, with 1KOMMA5° signing a multi-year supply contract with Wacker to secure high-quality and clean polysilicon. High social and quality standards are also maintained during further processing, and the module production sites are certified by TÜV Nord in accordance with the SA8000 ESG standard. This standard deals in particular with compliance with labour rights standards according to the UN Charter and international rules.

Yes, 1KOMMA5° solar modules can be used on any type of building. They achieve an output of 425 watts and are thus versatile. However, installation depends on various factors, such as the size of the roof and the positioning of the module in relation to the sun.

The 1KOMMA5° solar module has a module output of 425 watts and can therefore be used flexibly. This allows our customers to choose the module output that best suits their needs.

The power of PV modules is expressed in kilowatts (kW) and depends on various factors, such as size, efficiency, solar radiation and temperature. The power indicates how much electrical energy the module can produce, with higher power resulting in greater energy yield.

The 1KOMMA5° solar panel is black because it blends in better with its surroundings, especially the architecture of your home. In addition, the black colour of the panel can lead to a higher absorption of sunlight, resulting in higher energy production. The black colour is achieved by using dark materials such as monocrystalline silicon and black backsheet films.

A 425 watt solar panel can produce about 550 to 650 kWh of electricity per year in ideal conditions. However, the actual electricity production depends on various factors, such as location, orientation, solar radiation and temperature.

A solar module and a solar panel are often used interchangeably, but refer to different components of a solar system.

A solar module usually consists of several solar cells that are connected together and generate electrical energy.

A solar panel, on the other hand, is the entire system consisting of several solar modules and the associated electronics that feed the generated energy into the electricity grid or store it for use in a building or facility.

In short, a solar module is a unit of solar cells, while a solar panel is a group of solar modules that work as a system.

The 1KOMMA5° module is one of the most climate-friendly solar modules on the market. This is because we invest in a clean and local supply chain and start at the most critical part of the value chain: with the raw materials, or more precisely with the polysilicon. 1KOMMA5° relies on high-quality polysilicon from Germany and thus achieves a much lower CO2 footprint.

1KOMMA5° also offers a leading guarantee of 25 year product and 30 year performance warranty to safeguard the yield and profitability of our customers' systems. Overall, 1KOMMA5° modules stand for zero tolerance and maximum quality, because we rely on the highest social and quality standards throughout the entire supply chain.

The 1KOMMA5° solar panel is made of various materials, but the most important raw material is polysilicon. This is produced by the German company Wacker Chemie at its sites in Burghausen and Nünchritz. With Wacker's supply contract, 1KOMMA5° can secure access to high-quality, clean and ethical polysilicon. The majority of the raw materials required come from Asia.

Yes, 1KOMMA5° offers a guarantee for its solar modules. With a 25-year product and 30-year performance guarantee, we offer one of the leading guarantees on the market and, as a German company, ensure the yield and profitability of our customers' systems. In the event of damage, our customers can turn to our local master company for support.

The way polysilicon is manufactured has a high impact on the CO2 footprint of solar modules. 1KOMMA5° sources this raw material from Wacker Chemie. The company relies on renewable energies and the elimination of polluting chemicals in the production of polysilicon.

Particularly important here is the Siemens process, which produces high-purity polysilicon from silicon metal. Although this requires enormous amounts of energy, Wacker uses mostly renewable energies and thus achieves a carbon footprint around 50% lower than Chinese polysilicon, which is often produced using coal power.

The efficiency of solar modules indicates how much of the incident solar energy can be converted into electrical energy. Thanks to Top-Con technology, the 1KOMMA5° solar module achieves a module efficiency of up to 21.8%.

Black solar panels have some advantages over blue solar panels. Although they are more expensive, they are more aesthetically pleasing and blend in better with the look of buildings. In addition, they can absorb sunlight better due to their colour coating. In contrast, blue solar panels are less expensive, but their efficiency is usually slightly lower than that of black solar panels.

There are several ways to improve the efficiency of your solar panels:

• Positioning: Make sure your solar panel is oriented so that it constantly receives direct sunlight for optimal exposure.

• Cleanliness: Make sure the module is clean and free of dirt, dust and leaves. Ideally, the solar module should be cleaned every six months for maximum performance.

• Shading: Make sure that your solar module is not exposed to shading (from trees, buildings, etc.).

• Energy management system: Heartbeat optimises the self-consumption of solar power and ensures that it is used optimally to improve energy efficiency and reduce business costs.

• Upgrade to 1KOMMA5° solar module: Upgrading to higher quality solar modules or those with a higher efficiency class can also help to increase the efficiency of your solar module.
