Tenka Orion technology redefines efficiency in photovoltaics. At its heart is the patented Nanotech coating, which enables an exceptionally high light yield thanks to millions of tiny prisms on the cell surface. Even weak or diffuse light is efficiently captured and converted into electricity - a clear advantage in changing weather conditions or limited light incidence.
Tenka Orion modules achieve measurably higher energy yields than conventional modules, particularly at off-peak times and when the sky is overcast. This technology maximizes the energy yield per square metre and makes roofs with limited space economically viable. At the same time, it reduces installation costs as fewer modules are required for the same output.
The combination of nanotechnology and high-quality cell architecture makes Tenka Orion an ideal solution for all areas of application - from private house roofs to large open-space systems. The optimized use of light noticeably extends the daily generation time, which creates significant additional yields, especially in the morning and evening hours.
Tenka Orion technology also impresses with long-term use: low degradation, high material quality and constant performance ensure long-term investment security. Tenka Orion modules thus set new standards for sustainable and powerful PV systems - both technically and economically.
In the photovoltaic industry, manufacturers generally offer one and the same module in different output levels, for example 465 watts, 460 watts, 455 watts or 450 watts. These gradations are due to the varying quality of the solar cells produced, which do not all have the same efficiency. Manufacturers test the cells individually after production and then sort them according to their performance. This means that only the most efficient cells are used for modules with the highest output, while less efficient cells are installed in modules with lower output levels.
At Tenka, we pursue an uncompromising quality strategy so that we have set ourselves the goal of offering only modules of the highest performance level. In production, our solar cells undergo a particularly strict selection process, which ensures that only cells with maximum efficiency are used for the European region. This enables us to offer only solar modules with the highest available output. This ensures maximum energy yield, optimum use of space and long-term profitability of every PV system.

Monofacial solar modules only use the front side to generate electricity. The solar cells are only sensitive to light on one side and are embedded in a stable, opaque backsheet. This technology has been in use for decades and forms the basis for the majority of photovoltaic systems installed worldwide. Monofacial modules are robust, readily available and technically mature - a reliable standard in solar technology.
The modules consist of crystalline solar cells (usually PERC or TOPCon), which are protected by tempered glass on the front. The back is usually covered with plastic or glass, but is not translucent. This means that only the front can absorb sunlight and convert it into electrical energy. This clear focus on one active side considerably simplifies production, installation and system integration.
Monofacial modules impress with their cost efficiency and solid yields in a wide range of weather and site conditions. They are easier to install due to the one-sided use of light, do not require a special substructure and are therefore ideal for standard roof systems. The sophisticated technology offers many years of operational reliability and low degradation - a clear advantage when calculating PV investments.
Monofacial PV modules are mainly used on private house roofs, commercial roofs and industrial buildings. They are also a preferred choice for PV systems on carports or façades if there is no reflective surface. Thanks to their broad applicability, they are the first choice for PV projects where simple implementation, stability and cost control are paramount.
Bifacial solar modules convert sunlight into electrical energy on both the front and back. The solar cells are light-sensitive on both sides and embedded in transparent carrier materials such as glass. Thanks to this design, the modules also use reflected light from the ground or from the surroundings - a clear advantage over conventional monofacial modules.
Bifacial modules consist of double-sided active solar cells that are embedded between two panes of glass or in a glass-plastic composite. The rear side is translucent. Depending on the substrate - e.g. concrete, gravel or snow - reflective light can additionally activate the rear side and increase the total energy yield by up to 30 %.
The major advantage of bifacial modules is their higher specific energy yield, particularly with reflective substrates and optimum mounting angles. They offer improved area utilization, higher efficiencies and are particularly resistant to environmental influences. Even in diffuse lighting conditions or when the sun is low, they provide additional energy and thus increase overall efficiency.
Bifacial modules are preferably used in ground-mounted systems, on flat roofs with a reflective substrate or in agricultural PV systems. They also achieve good yields on carports or systems with an east-west orientation. They are particularly suitable where sufficient light is reflected from behind and the highest possible total output per area is to be achieved.
In photovoltaics, PERC and N-type TOPCon cells are two of the most important technologies currently dominating the market. Both variants are based on monocrystalline silicon, but differ in terms of their cell architecture, efficiency and durability. While PERC modules represent the established industry standard with a solid price-performance ratio, TOPCon technology relies on state-of-the-art cell contacts and optimized material properties to achieve maximum energy yield. Planners, installers and investors are therefore increasingly faced with the question of which solution makes the most economic and technical sense for which project environment.
The following comparison shows key differences between the two cell technologies - from efficiency and temperature behavior to long-term yields and degradation behavior. It is not just about theoretical parameters, but above all about the practical benefits in various application scenarios - for example, where space is limited, specific climatic conditions or budget constraints. Whether a large-scale solar park, industrial building or private home: choosing the right cell technology can determine the long-term economic success of a PV system. With an informed decision, performance and return on investment can be optimized in a targeted manner.
PERC stands for "Passivated Emitter and Rear Cell" and is a further development of classic monocrystalline solar cells. The special feature lies in the passivation of the rear side, which reflects unused sunlight and thus increases efficiency. Thanks to its proven design and mature production processes, PERC technology is one of the most widely used cell architectures in photovoltaics today.
In a PERC solar cell, the rear side is passivated with a dielectric layer that reduces recombination losses and reflects unused light back into the cell. At the same time, it improves electrical passivation, which means that fewer charge carriers are lost. Easy integration into existing production lines and moderate efficiencies of between 20% and 22% make PERC an efficient and economical standard solution.
The advantages of PERC technology lie primarily in its proven, stable performance, low manufacturing costs and broad market coverage. PERC modules offer a very good price-performance ratio, are suitable for large volume projects and are readily available worldwide. Thanks to their simple process control, they are extremely reliable and have been tried and tested over many years.
PERC modules are used in almost all areas of application - from residential buildings to commercial roof systems or large open-space parks. They are ideal when production costs are the focus and a stable yield with good efficiency is required. PERC is also often the first choice in markets with high price sensitivity.
The N-type TOPCon technology (Tunnel Oxide Passivated Contact) is a modern cell architecture based on n-type silicon. In contrast to PERC cells, TOPCon relies on an optimized back-surface structure with additional layers that enable more efficient power generation. TOPCon modules are technologically more sophisticated and achieve higher efficiencies.
At the center of TOPCon is an extremely thin tunnel oxide layer which, together with a polycrystalline silicon layer, establishes contact with the back surface. This combination reduces electrical resistance and improves charge carrier transport. The use of n-type wafers also significantly reduces light-induced degradation (LID).
TOPCon modules achieve efficiencies of over 24 % and are characterized by higher yields with less degradation. They work particularly well in low light and at high temperatures and retain their performance over their entire service life. The higher bifaciality of bifacial designs also contributes to the increase in yield.
TOPCon modules are preferably used where maximum output is required in a limited space - for example on industrial roofs or areas with high irradiation. They also demonstrate their strengths in particularly hot or poorly lit regions. TOPCon is a future-proof technology for premium projects or demanding customers.

Solar panels are considered one of the most environmentally friendly energy sources as they generate renewable energy directly from sunlight. Unlike fossil fuels, solar panels do not produce greenhouse gas emissions when generating electricity, making them a key solution in the fight against climate change. The use of solar systems helps to reduce CO₂ emissions and reduces the need for environmentally harmful fossil fuels.
While the production of solar modules requires energy and resources, the ecological footprint over the lifetime of the system is very small. Modern solar modules have a lifespan of 25 to 30 years and are largely recyclable. This means that the environmental impact of production and operation is significantly lower compared to conventional energy sources such as coal or natural gas.
Solar systems also offer the advantage that they can be installed decentrally, whether on roofs, open spaces or in rural areas. This minimizes energy losses due to long transport routes. All in all, solar systems are a clean, efficient and environmentally friendly way of meeting energy requirements and protecting the environment at the same time. Investing in a solar system is therefore not only an economical decision, but also a significant contribution to climate protection.
The space required for a solar installation depends mainly on the desired output and the solar modules used. An average solar system requires around 6 to 10 square meters of roof space for 1 kWp (kilowatt peak). A typical system with 5 kWp, which is enough to cover the electricity needs of an average household, would require around 30 to 50 square meters.
The space requirements can also depend on the efficiency of the solar modules. Highly efficient modules can produce more solar power on less surface area, which reduces the amount of space required. The orientation of the roof and the angle of inclination also play a role, as an optimal orientation to the south and an angle of inclination between 30 and 40 degrees maximizes the efficiency of the modules.
If there is not enough space on the roof, there are also alternatives such as ground-mounted systems, façade installations or carports with solar panels. These options allow you to generate your own solar power even without a large roof. Overall, the available space should be carefully planned in order to exploit the maximum energy potential of the solar system and optimize its cost-effectiveness.
Solar cells offer numerous advantages as an energy source and are an environmentally friendly, sustainable alternative to fossil fuels. By converting sunlight into electrical energy, solar cells provide clean and renewable electricity. They help to reduce dependence on conventional energy sources and at the same time promote the reduction of CO2 emissions, which is an important contribution to climate protection.
A key advantage of solar energy is its inexhaustibility. The sun is an unlimited source of energy, unlike fossil fuels such as coal, oil or gas, which are finite and harmful to the environment. In addition, solar cells produce electricity without noise and without pollutants. This makes them an ideal solution for private households, commercial enterprises and industries that want to rely on a sustainable energy supply.
Solar cells also offer many financial advantages. By using solar power, you can significantlyreduce your energy costs. Installing a solar system is a long-term investment that can quickly pay for itself through savings on electricity costs and government subsidies. In addition, having your own solar system increases the value of your property, as more and more buyers are looking for environmentally friendly and energy-efficient homes.
Continuous technological advances are making solar cells ever more efficient and cost-effective, further increasing the attractiveness of this energy source. Overall, solar cells are a future-proof solution that offers both economic and environmental benefits.
Solar cell maintenance is crucial to ensure the maximum efficiency and longevity of your solar installation. Although solar cells are generally very low maintenance, regular inspections and cleaning can significantly improve performance. Dirt, dust, leaves or bird droppings can affect energy production , which can lead to reduced performance.
Regular cleaning of the solar cells is particularly important in regions with high levels of dust or air pollution. Clean solar modules capture more sunlight and therefore produce more electricity. It is advisable to check and clean the modules at least once a year, especially after heavy storms or long dry periods during which dirt can accumulate.
In addition to cleaning, inspection of the electrical components plays an important role. The inverter, cabling and fastening elements should be checked regularly for damage. A well-maintained system not only ensures higher electricity production, but also extends the service life of your solar installation. Problems such as faulty cabling or damaged modules can be detected early and rectified before they cause major damage.
The investment in regular maintenance is small compared to the potential losses caused by inefficient solar cells. With careful maintenance, your system will remain productive and efficient for many years. A well-maintained solar system therefore not only offers you financial benefits, but also makes a major contribution to the energy transition.
Solar cells are a key component of the global energy transition and play a crucial role in accelerating the transition from fossil fuels to renewable energy. By converting sunlight directly into electricity, solar cells provide a clean, sustainable source of energy with zero CO2 emissions. This makes them an essential tool in the fight against climate change.
A major advantage of solar cells is their flexibility. They can be installed on roofs, in solar plants or in open spaces to generate clean electricity without harming the environment. These decentralized energy sources reducedependence on central power grids and create new opportunities for self-determined energy production.
The use of solar cells makes it possible to reduce energy consumption and at the same time reduce dependence on fossil fuels such as coal, gas and oil. This helps to reduce CO2 emissions and combat climate change. In combination with storage technologies and intelligent energy management systems, solar cells can ensure a constant supply of energy, even when the sun is not shining.
Together with other renewable energy sources such as wind and hydropower, solar cells play a key role in creating a sustainable, clean and climate-friendly energy system. Their continuous further development ensures that the energy transition progresses faster and the share of renewable energies increases worldwide.
Solar cells have seen a considerable increase in efficiency in recent years. Modern solar cells utilize a larger proportion of solar energy and achieve efficiencies of up to 24% and more. The efficiency depends on the technology used. Monocrystalline solar cells offer the highest efficiency, followed by polycrystalline and thin-film solar cells. These advances make it possible to generate a significant amount of electricity even with less solar radiation.
Choosing the right solar cells plays a decisive role in the cost-effectiveness of the entire system. Monocrystalline solar cells are more expensive, but their higher efficiency means that they make better use of the available space on the roof. Polycrystalline solar cells are cheaper, but have a lower efficiency, which means that more space is required to generate the same amount of electricity.
Another aspect that influences efficiency is the environment. Dust, dirt and shade can reduce the energy yield. For this reason, it is important to clean the solar cells regularly and ensure that they are optimally aligned to capture the maximum amount of sunlight.
The continuous development of solar cell technology ensures that efficiency continues to improve. New materials and technologies such as multi-junction solar cells, which use different spectra of light, could enable even higher efficiency values in the future.
The amount of electricity that a solar system produces depends on several factors. These include the size of the system, the efficiency of the solar modules, the solar radiation at the location and the orientation and inclination of the solar modules. Under ideal conditions, a well-planned solar system can generate a considerable amount of electricitythat can be used both for self-consumption and for feeding into the grid.
In regions with high levels of solar radiation, a solar system can generate between 900 and 1,300 kilowatt hours of electricity per installed kilowatt peak (kWp) per year. The exact output varies depending on the geographical location and the efficiency of the installed modules. Modern solar modules have a high degree of efficiency and can still produce electricity even in cloudy weather or indirect sunlight.
By combining this with a battery storage system, the surplus electricity produced can also be stored for later, which increases energy independence. This is particularly advantageous as it minimizes dependence on external energy suppliers and maximizes self-consumption.
A well-planned solar system can cover the entire electricity requirements of a household or business and also feed surplus energy into the public grid, which is additionally rewarded by feed-in tariffs. With the right dimensions and orientation, your solar system will become an efficient and sustainable source of energy.
The inverter is a central component in every solar power system, as it converts the direct current (DC) generatedby the solar modulesinto alternating current (AC), which is used in households and in the electricity grid. Without an inverter, the electricity generated would not be usable for most applications. Its role is therefore crucial in making the energy from the solar system available for everyday use.
An efficient inverter ensures that most of the electricity generated by the solar modules is converted into usable alternating current, minimizing losses during the conversion process. Inverters are available in various designs, depending on the size and type of solar system. They constantly monitor the performance of the system and optimize the flow of electricity, resulting in a higher energy yield.
In addition to converting electricity, the inverter also performs important safety functions, such as protection against overloads and short circuits. Modern inverters also have smart functions, such as remote monitoring via apps or integration into energy management systems. These functions offer real-time monitoring and make it possible to optimally control the performance of the solar system.
A high-quality inverter therefore makes a significant contribution to the efficiency and longevity of the entire solar system. It ensures maximum energy yield and protects the system from potential damage.
A solar system not only offers ecological benefits, but also significant economic advantages. By using solar power, you can significantly reduce your electricity costs in the long term and contributeto the energy transitionat the same time. The investment in a photovoltaic system usually pays for itself within a few years, depending on the location and solar radiation.
Saving on energy costs: By producing your own electricity, you reduce your dependence on rising energy prices. Every kilowatt hour that you generate yourself reduces your monthly electricity bill. This leads to considerable savings over the lifetime of the system.
Attractive subsidies: Government subsidy programs and feed-in tariffs make the purchase of a solar system even more lucrative. Many countries offer attractive financial incentives for the purchase and installation of photovoltaic systems, which shortens the amortization period and increases profitability.
Increasing the value of your property: Installing a photovoltaic system can increase the value of your property. As more and more buyers are paying attention to energy efficiency, a property with a solar system is seen as more attractive. This can have a positive effect on the resale value.
In addition to the financial benefits, the use of solar energy offers a secure and long-term solution for energy generation that is independent of fossil fuels. This protects you from future price fluctuations on the energy market and contributes to the sustainability of your household or business.
