Shingle solar modules

Shingle solar modules, also known as "Shingled Modules", represent an innovative further development of photovoltaic technology. Instead of consisting of large, continuous solar cells like conventional solar modules, they rely on many small, overlapping solar cells that are arranged on a module like roof shingles.

How it works:

• Overlapping shingles: The individual shingles, usually made of monocrystalline silicon, overlap slightly. This means that no valuable gaps are lost and the entire module area is used effectively.
• Partial shading: The overlapping arrangement allows light to fall onto other shingles and generate electricity, even if individual shingles are partially shaded. This leads to a significantly lower power loss compared to conventional modules, which is particularly advantageous on roofs with trees, chimneys or other shade sources.
• Electrical connection: The shingles are connected to each other using electrically conductive adhesives and copper wires. In this way, the electricity generated is efficiently dissipated.
• Protection and stability: The shingles are embedded in glass, which ensures high robustness and longevity. Glass as a carrier material also offers optimal light transmission and protects the solar cells from environmental influences.

Advantages of shingle solar panels:

• Higher yield: With less interference from shadows, shingle solar panels generate more energy per square meter of roof area.
• Higher efficiency: The overlapping arrangement and optimized cell technology lead to higher efficiency.
• Aesthetic design: The flat, homogeneous surface and elegant look make shingle solar modules an attractive design element for roofs.
• Robustness: The glass-glass construction offers protection from the elements and makes the modules more resistant to hail and impacts.
• Longer lifespan: Due to lower degradation and robust construction, shingle solar panels potentially have a longer lifespan than traditional panels.

Disadvantages of Shingle Solar Panels:

• Higher costs: The acquisition costs of shingle solar modules are currently higher than those of conventional modules.
• Lower availability: The technology is still relatively new, so the choice of manufacturers and models is limited.
• More complex installation: Installation requires a little more expertise due to the large number of smaller components.

Conclusion:

Shingle solar panels offer a number of advantages over traditional panels and can be an attractive option for homeowners who want high efficiency, elegant design and a long lifespan from their solar system. However, the higher costs and lower availability are currently still hurdles for widespread use. However, as technology advances and prices fall, shingle solar panels are likely to play a larger role in the market in the future.

Greater efficiency:

• Better use of space: Due to the overlapping arrangement of the shingles and the absence of gaps, the entire module area is better utilized.
• Lower power losses: With conventional modules, defective cells or partial shading can affect the entire module series. Shingle modules, on the other hand, are divided into small, independent units so that individual cell failure or shadow exposure causes only limited power loss.
• Higher yield in low light: The shingle technology enables better light yield in diffuse lighting conditions, as the individual cells work effectively even at an oblique angle of incidence of sunlight.

Longer service life and robustness:

• Less cell breakage: The smaller and more flexible shingles are less susceptible to breakage from mechanical influences such as hail or wind.
• No hotspots: Due to the decentralized arrangement of the power conductors and the better cooling of the cells, there are no “hotspots” that can affect the performance and service life of the module.
• Resistant to environmental influences: Shingle modules are more resistant to moisture, extreme temperatures and corrosion.

Aesthetic benefits:

• Homogeneous appearance: The overlapping arrangement of the shingles creates a smooth, even surface that is more visually appealing than typical modules with visible gaps and frames.
• Flexible design options: Shingle modules can be manufactured in different colors and shapes so that they can be better adapted to the architecture of the building.

Additional advantages:

• Easier installation: The individual shingles are easier to assemble and transport than bulky, heavy modules.
• Higher snow load: Due to the flat design and better distribution of the load, shingle modules can carry higher snow loads than conventional modules.
• Sustainable production: The production of shingle modules requires less material and energy than the production of conventional modules.

Disadvantages:

• Higher costs: Shingle modules are currently slightly more expensive than conventional modules.
• Lower availability: The technology is still relatively new and therefore shingle modules are not available from all manufacturers.

Conclusion:

Shingle solar panels offer a number of advantages over traditional panels, particularly in terms of efficiency, lifespan, aesthetics and sustainability. The higher acquisition costs are partially offset by the higher yields and longer lifespan. However, as technology advances and demand increases, shingle panel prices are expected to decrease in the future.

Higher cost:

• Acquisition costs: Shingle modules are currently significantly more expensive than conventional solar modules. Prices can be up to twice as high. This is partly due to the new technology, which is not yet mass-produced, and partly due to the higher quality materials used for the shingles.
• Installation costs: Installing shingle modules can also be a little more complex and expensive than installing traditional modules. This is due to the more complex installation technology and the higher number of individual components.

Lower availability:

• Technology: Shingle technology is relatively new and still in development. Therefore, shingle modules are not yet available from all manufacturers and the selection of models is limited.
• Installers: Not all solar installers are familiar with shingle panel installation. Therefore, it can be more difficult to find a qualified installer who can carry out the installation professionally.

Long-term experience:

• Proven technology: Conventional solar modules have been a proven technology for decades. However, there is not yet sufficient long-term data on the performance and service life of shingle modules.
• Repair: Since shingle technology is relatively new, there is no long-term experience with repairing shingle modules. It is therefore unclear how easy and cost-effective it will be to repair broken shingles or other components.

Other:

• Weight: Due to the materials used, shingle modules are slightly heavier than conventional modules. This can be problematic when installing on roofs with structural limitations.
• Recycling: It is still unclear how shingle modules can be recycled at the end of their life. Dismantling and recycling the individual shingles could prove difficult and time-consuming.

Conclusion:

While shingle solar panels offer some key advantages over traditional panels, there are also some disadvantages to consider. The higher costs, the lower availability and the lack of long-term experience are currently the biggest obstacles to wider application of shingle technology.

However, these disadvantages are expected to diminish as technology advances and demand increases. In the long term, shingle solar panels could represent an attractive alternative to traditional panels, especially for homeowners who value aesthetics, efficiency and durability.

Due to their unique properties, shingle solar modules offer various advantages that make them particularly attractive for certain target groups:

1. Homeowners with aesthetic demands:

• Homogeneous appearance: The overlapping arrangement of the shingles creates a smooth, even surface that can be harmoniously integrated into the roof design and ensures a visually appealing overall appearance.
• Flexible design options: Shingle modules are available in different colors and shapes so that they can be individually adapted to the architecture of the house. This allows homeowners who value a high-quality appearance to harmonize their solar system with the design of their home.

2. Homeowners with complex roof surfaces:

• High adaptability: The individual shingles can be easily adapted to uneven or curved roof surfaces as they can be installed flexibly. This enables the use of solar potential even on roofs that are unsuitable for installing conventional modules.
• Less interference from shadows: Due to the overlapping arrangement and the high partial shading tolerance of the shingles, even areas of the roof with partial shading can be effectively used for electricity generation.

3. Caravan and mobile home owners:

• Light weight and high flexibility: Shingle modules are significantly lighter and more flexible than conventional modules, making them ideal for installation on mobile homes and caravans. The simple assembly allows for independent installation without much effort.
• Higher output in low light: Shingle technology allows for better light output in diffuse lighting conditions, which is particularly beneficial in campsites or heavily wooded environments where direct sunlight is often limited.
