Shingled solar cells are solar cells which are cut into typically 5 or 6 strips.  These strips can be overlaid, like shingles on a roof, to form the electrical connections.  The strips of solar cells are joined together using an electrically conductive adhesive (ECA) that allows for conductivity and flexibility.

This allows the cells to be connected differently to conventional solar panels, in that, there are no busbars (ribbons) required and the solar cells can be joined together resulting in no gaps between the solar cells.

Shingled solar modules can also be wired differently to conventional solar panels.  Typically, solar cells in conventional solar panels are wired in a series of strings whereas the solar cells in shingled panels can be wired in parallel configuration.

What are the advantages of shingled solar panels?

Essentially the three key advantages of the shingled solar panel design are they produce more power, improve reliability and are aesthetically pleasing.

1. Increased energy harvest

Higher power per square metre

The shingled solar cells do not require busbars across the top of the cells so more of the solar cells are exposed to sunlight.  The cells do not need to be spaced apart like in conventional solar panels so the solar panel area can produce more energy.

Comparison between conventional solar panel and Solaria shingle solar panel

Less energy loss due to shading

Conventional solar panels have the individual cells wired in series so when a part of the solar panel is shaded it can have a significant effect on the level of power output.  By configuring the solar cells in shingles, they can be wired in groups and configured in parallel which significantly reduces the losses caused by shading.

Current flow comparison

Below are some examples of shading and losses for a conventional solar panel and a shingled panel.  The Shingled panels have greater performance except for the vertical shading example.

Outdoor shade testing over a 70-day period has shown that the  shingled solar panel performs between 37 to 45% better than conventional solar panel designs.

2. Better reliability

Low busbar failures

Shingle solar panels do away with approximately 30 metres of busbar and soldered joints that is required on conventional solar panels, so busbar failures are reduced.

Better mechanical performance

Static and dynamic load tests show that the shingle approach is more resistant to failure due to external forces being applied to the solar panel compared to conventional solar panels.

3. More attractive

Shingled solar panels have no visible circuitry which give them clean simple look providing superior street appeal.

In the face of climate change, the world is evolving rapidly, and it comes an urgent need of sustainable energy solutions. One of the innovative solutions to this global problem is Building Integrated Photovoltaics (BIPV). These solar panels not only serve the dual purpose of providing power and generating electricity for house, but also shaping the future urban infrastructure. Let's rearch deeper for why BIPV is not only a viable option for modern construction, but the preferred choice.

Benefits of BIPV Panels

Building-integrated solar panels offer house owners and businesses a unique solution. They are not just additions to the existing structure; they are embedded within the structure itself. Because they act as both a building envelope and an energy generator, no need for a separate solar installation, providing functionality and aesthetics.

Space Efficiency

Building-integrated solar offers unique advantages in urban environments where space is at a premium. By integrating solar panels directly into building facades or roofs, no additional land or space is required to accommodate large solar farms. This efficient use of space is especially beneficial in densely populated areas. By choosing vertical or rooftop solar installations in urban environments, we can leave more land undisturbed. This approach protects natural habitats and supports biodiversity, unlike large ground based solar farms that sometimes damage local eco systems.

Resource Efficiency and Environmental Impact

Integrating solar panels into buildings reduces the need for additional materials and space. This means fewer resources are used and less waste is produced. By reducing the amount of raw materials required for construction and installation, we minimize our environmental footprint and pressure on natural resources. Additionally, because solar energy is green and renewable, it significantly reduces buildings' carbon footprint.

Design Flexibility

A building's aesthetics are an integral part of its appeal, value, and ability to blend in or stand out in its environment. Building-integrated solar panels continue to develop not only as functional components, but also as design elements that can enhance the attractiveness of buildings.

Thanks to advances in technology and manufacturing techniques, building-integrated photovoltaic systems can be integrated into a variety of building styles, from traditional to contemporary. This ensures that the integration of solar panels does not compromise the building's original design vision, but rather complements or even enhances it.

With modern technologies, roof-integrated systems can be customized to match a variety of architectural styles. Whether you want to integrate with existing roof tiles or achieve a seamless look, you have the flexibility to accommodate any design preference.

BIPV offers a range of design options. This includes different colors, textures and opacity. Some BIPV solutions even mimic materials like slate or terracotta, allowing architects and house owners to maintain a specific aesthetic while still reaping the benefit of solar energy.

While rooftops are a common site for building PV integration, the technology's adaptability means it can also be used on facades, awnings, or even as part of a building's shading system. This broadens design possibilities and enables architects to think creatively about how and where to incorporate solar power into their designs.

Photovoltaic Building Integrated Applications

1. Awnings and canopies. Outdoor structures such as awnings. Awnings are ideal for building-integrated photovoltaics, capturing sunlight while providing shade.

2. Facades. BIPV facades convert building appearance into energy, blending aesthetics with functionality. Large glass curtain wall can be equipped with translucent integrated solar panels that filter sunlight while generating energy.

3. Balcony and terrace. Integrating building-integrated photovoltaics into a balcony or terrace.

4. Roof installation. Rooftop installations are the most common application of building-integrated photovoltaics, blending seamlessly with the contours of the building. Here, the roof not only acts as a barrier against the elements, but also acts as a solar generator.

Because batteries power electric vehicles and the battery power entirely determines their range. Therefore, the anxiety and pressure caused by when trying to adopt or use EVs due to the worry or fear that the electric vehicle does not have enough power to support it to reach its destination or a reliable charging station is called range anxiety. It is particularly obvious when long-distance travel is required.

However, unlike the flexibility of private passenger cars in route planning, for commercial fleets, fleet managers must ensure delivery time and efficient operation of the entire fleet. Therefore, the challenges brought by commercial fleets' range anxiety will be more, mainly reflected in the following aspects:

· Ensuring the scheduled delivery times and reducing the risk of financial compensation.

· Optimizing transportation route planning before executing tasks.

· Ensuring fleet operational efficiency, reducing the possibility of operational interruptions, lowering operating costs, and increasing profits.
