Solar panels
In the dynamic world of renewable energy sources, photovoltaics – and therefore solar panels – play a key role. As an experienced photovoltaic wholesaler, Krannich offers a wide range of high-quality solar panels characterized by high efficiency and long service life. Here you will find all the key information about solar panels that is essential for installers and photovoltaic professionals. Solar panel technology is constantly evolving. It is therefore essential for electricians and photovoltaic experts to keep pace with the latest developments so they can make the right decisions for their customers and projects. At Krannich, your trusted partner for solar technology, you will find a wide selection of panels that meet the latest technological standards.
Technical basics of solar panels
Solar panels – also known as photovoltaic panels – are the basic elements of every solar power system. They convert solar radiation into electrical energy. They consist of several solar cells made from semiconductor materials such as silicon. The technology, materials used, and manufacturing processes are continuously developing.
Types of solar panels
Below, we take a look at selected panel technologies and designs
Glass-glass vs. glass-foil
When selecting panels, installers choose between glass-glass and glass-foil construction. Glass-glass panels have two layers of glass that protect the cells and ensure a long service life. Glass-foil panels use a combination of glass on the front side and a polymer foil on the rear side – they are lighter and more cost-effective, although potentially less durable.
Bifacial panels
Bifacial panels absorb light from both the front and rear sides. They use not only direct sunlight but also reflected and diffused light – which increases the output of the entire installation. They are ideal for use above light-colored or reflective surfaces.
N-type and P-type panels
The choice between N-type and P-type depends on the specific project requirements. N-type panels offer higher efficiency and better resistance to light-induced degradation (LID). P-type panels are generally more affordable and have a long-proven track record of performance.
Full Black panels
Full Black panels are valued for their uniform black appearance: dark cells, a black frame, and often a black backsheet as well. They blend perfectly into architecture and are ideal for installations where aesthetics also matter – for example on family homes or in heritage-protected areas.
How to choose the right solar panel?
Various factors play a role in the selection: power and efficiency, manufacturer warranties, resistance to hail and fire, resistance to salt mist and ammonia, maximum mechanical load, price/performance ratio.
At Krannich, you will find panels with different outputs, dimensions, and technologies – suitable for a wide range of applications.
Advantages of wholesale purchasing
Purchasing solar panels wholesale offers a number of advantages. At Krannich, we offer attractive discounts for larger volumes – for example when ordering by the container. This enables cost-effective supply and increases project profitability. Of course, we also deliver smaller orders assembled to individual requirements.
Sustainability and environmental benefits
Solar panels are among the most efficient and most sustainable sources of renewable energy. During their lifetime, they produce approximately 12 times more clean energy than was needed for their production. This significantly reduces greenhouse gas emissions compared to other energy sources. Krannich places great emphasis on the environmental parameters of the products it offers.
Training and professional education
Want to stay up to date? Take advantage of Krannich’s regular training sessions and webinars, where you can learn all about the latest developments in the world of solar energy and deepen your technical knowledge. Solar panels are a fundamental building block of every photovoltaic installation and an important tool for the transition to clean energy. They offer an efficient and environmentally friendly way to generate electricity.
Krannich Solar as an experienced wholesaler offers a wide selection of high-quality panels as well as expert support – from consulting and supply to training.
