Technical Foundations of Solar Modules

Solar modules, also known as photovoltaic modules, are the core components of a solar system. They convert sunlight into electrical energy. Each module is made up of multiple solar cells composed of semiconductor materials like silicon. Technologies, materials, and production methods are constantly advancing, which influences module design and performance. 


Types of Solar Modules 

Below, we take a closer look at key aspects of solar module technology: 


Glass-Glass vs. Glass-Film Modules 

Installers must decide between glass-glass and glass-film modules. Glass-glass modules feature two layers of glass that protect the solar cells and provide excellent durability. Glass-film modules combine a glass front with a polymer backsheet. They are lighter and were long considered more cost-effective but may be less durable. 


Bifacial Modules

Bifacial modules absorb sunlight from both sides. This allows them to make use of reflected and diffuse light, increasing total energy output. They are particularly effective in installations with reflective surfaces. 


N-Type vs. P-Type Modules

Choosing between N-Type and P-Type modules depends on project-specific factors. N-Type modules offer higher efficiency and better resistance to light-induced degradation (LID). P-Type modules are typically more affordable and have a long track record of reliable performance.


Full Black Modules

Full Black modules are favored for their sleek, uniform appearance. They feature dark cells, a black frame, and – depending on design – a black backsheet. These modules integrate beautifully with modern architecture and are ideal for projects where aesthetics matter as much as performance.

Choosing the Right Solar Module

Several factors influence module selection: power rating, efficiency, warranties, hail and fire safety classifications, resistance to salt mist and ammonia, mechanical load capacity – and, of course, performance-to-price ratio. At Krannich, you’ll find modules in various performance classes, sizes, and technologies, suitable for a wide range of needs and system types.

Wholesale Purchasing: Benefits for Professionals

Buying solar modules through a PV wholesaler offers clear advantages. At Krannich, customers benefit from attractive volume discounts, such as when ordering by the container. This enables cost-effective procurement and enhances overall project profitability. Naturally, we also support small, pre-picked orders for flexible needs.

Sustainability and Environmental Impact

Solar modules are among the most sustainable and cost-effective forms of renewable energy. Over their lifespan, they produce approximately 12 times more clean energy than was consumed during their manufacturing. This results in a significant reduction in greenhouse gas emissions compared to most other energy sources. At Krannich, we place great emphasis on offering environmentally responsible products.

Training and Continuing 

Education Staying up to date with the latest technology is vital. That’s why Krannich Solarregularly offers training courses and webinars to help professionals expand their knowledge and stay informed about the latest developments in the PV industry.

Solar modules are essential components of photovoltaic systems and renewable energy generation overall. They offer a highly efficient and eco-friendly solution for producing electricity. As an experienced PV wholesaler, Krannich Solaroffers a comprehensive selection of high-quality, durable solar modules. Installers benefit from our full-service support – from consultation and procurement to technical training and beyond.
