Trends in solar modules in 2024

Current developments in solar modules show a strong shift towards high-performance monocrystalline modules with N-type cells in TOPCon and HJT technology. These modules achieve efficiency values of over 21% and a nominal output of 400 Wp or more, making them particularly attractive for commercial use and demanding projects. Bifacial modules are also becoming increasingly important: up to 30 % more energy can be generated by using light-active cells on both sides. The advanced half-cut technology and multi-busbar technologies (9BB and 12BB) further increase efficiency and reduce power losses.

Which solar module is the best?

The choice of the best solar module depends on the individual requirements:

Commercial projects: Modules with a low LCOE (Levelized Cost of Electricity) offer long-term cost-effectiveness.
Private applications: Aesthetic aspects and high efficiency with limited space play a major role here.

Guarantees and the reliability of the manufacturer also influence the decision. Manufacturers such as LONGi Solar, Jinko Solar and Trina Solar score points with excellent guarantees and proven quality.

The top 10 solar module manufacturers in 2024

In 2024, the following manufacturers have established themselves as leaders:

These companies are the best suppliers of photovoltaic modules in the world due to their quality, technological innovations and reliable warranty services.

Solar modules from Europe

European solar modules offer a perfect combination of regional production, high efficiency and sustainability. They meet the strictest environmental standards and guarantee a high level of reliability. One example of this is DMEGC Solar, a company with roots in China that has successfully focused on the European market. With high-performance modules that are ideal for large-scale projects and installations, DMEGC focuses on European quality requirements and offers a competitive solution for the industry.

Where can I buy solar modules?

Solar modules are available via specialized online marketplaces and from solar installers. For private individuals, it is advisable to seek advice from specialist companies, as they take care of installation and maintenance. Solar platforms such as Solartraders offer comprehensive comparison options and price advantages for bulk buyers and commercial projects.

Wp for solar modules - what does it mean?

Wp, short for Watt Peak, indicates the output of a solar module under standard test conditions. This key figure is important for comparing modules with each other, as factors such as temperature, position of the sun and irradiation influence the actual output. The information is on the module's data sheet and provides a valuable basis for comparison.

How much electricity does a solar module generate?

The power generation of a solar module depends on various factors, such as the rated output in watt peak (Wp), the geographical location, the module orientation, the angle of inclination, shading and the technology. In sunny regions, a module can generate up to 40 % more energy than in less sunny areas.

A solar module with 450 Wp generates around 450-500 kWh of electricity per year in Germany. In sunny regions such as Spain or Italy, the figure is 600-650 kWh. For a detached house with an annual electricity requirement of around 4,000 kWh, 8-10 modules are required.

Modern technologies such as bifacial modules or TOPCon cells can further increase energy production. Choosing the right module maximizes the potential of solar energy.

Monocrystalline or polycrystalline solar modules?

Polycrystalline modules are hardly relevant in the commercial market anymore, as monocrystalline modules dominate in terms of both performance and efficiency. With technological advancements and price reductions, they will be the standard in almost all areas of application in 2024.

Solar module and inverter - an important combination

An inverter is essential for the operation of solar modules in grid-connected systems. This converts the direct current generated into alternating current. Brands such as SMA, Fronius and SolarEdge offer highly developed solutions that ensure optimum energy feed-in. Precise dimensioning prevents power losses and maximizes efficiency.

Solar module and solar storage - flexibility and independence

The combination of solar modules and storage systems is becoming increasingly popular, especially in the private sector. Manufacturers such as BYD and Huawei offer flexible storage solutions that increase self-consumption and enable greater independence from the grid.

Mechanical resilience and weather resistance

Modern solar modules offer high resistance to extreme weather conditions. Standard modules can withstand snow loads of up to 5400 Pa and wind loads of up to 2400 Pa. Glass-glass modules or modules with reinforced frames are ideal for regions with extreme weather conditions.

Guarantees from solar module manufacturers

Solar module manufacturers generally offer a product guarantee of 12 to 15 years and a performance guarantee of 25 years or more. These guarantee a minimum output after a specified period of operation and offer buyers long-term security. An informed choice of an established manufacturer is crucial here.
