Vehicles

Lightweight and flexible

Our flexible solar panels use a thin-film technology called copper-indium-gallium-selenide (CIGS). Unlike traditional crystalline glass panels, these panels offer unmatched versatility. With a thickness of only 3 mm and a weight of 2.2 kg per square metre, you can install them on low load capacity roofs, curved surfaces, vehicles and more.

High efficiency and production

CIGS solar panels have higher efficiency than conventional silicon solar panels thanks to their high absorption coefficient and ability to utilise a wider spectrum of sunlight. This means they start producing electricity earlier in the morning and continue to produce power until late in the evening.

Resistance to shade and temperature

Another significant advantage of CIGS is that these panels are minimally affected by variations in temperature and shade, ensuring stable performance throughout the day. Even with 10% shading, CIGS performance only drops by 10-20%, while crystalline panels typically experience reductions of 60-80%. Furthermore, the output of CIGS panels is significantly less affected by high and low temperatures compared to other solar technologies.

Buildings

High safety and reliability

CIGS panels are known for their robustness and reliability in various conditions. Their unique flexibility and robust design ensures that they can withstand different weather conditions and impacts without the risk of hotspots or micro-cracks. Even under intense and unstable conditions, the panels maintain their reliable performance and long lifespan. In fact, they are tested to withstand loads of up to 250kg despite being only 3mm thick.

Minimal environmental impact

In addition to its high efficiency and flexibility, CIGS technology is also more sustainable than other technologies. With only 3% of the raw materials needed compared to C-Si solar cells, CIGS solar panels have a minimal environmental impact. They do not emit harmful gases or substances and require fewer materials to produce. The materials used in production come from sustainable sources, with copper extracted from cable scrap, and indium, gallium and selenide extracted through recycling and refining processes (Button: Sustainability).

Optimised space utilisation

CIGS panels have a high energy density. This means more power on smaller surfaces, which is ideal for busses and trucks with a limited roof size. They can be glued on without the need for drilling holes and can be adapted to the surface, making it possible to install on the vehicle.

Minimal loss of performance at high temperatures

CIGS solar panels are designed to thrive in both cold and hot environments without fire hazards, damage, or reduced performance. Their efficiency remains consistent in changing weather conditions, providing drivers assurance of a reliable power supply regardless of temperature fluctuations.

Explainer

How solar panels generate electricity

CIGS solar panels convert sunlight into electrical energy. They are activated by the light itself and not the sun’s rays. When it is cloudy, our solar panels will still produce electricity to a certain extent. The solar cells are assembled into solar panels, and several solar panels can be joined together to create a solar system that can supply the required amount of power to a home or business – depending on need.
When sunlight hits the solar panel, it creates electrical charges that produce a current. This current can be used to power electrical appliances or stored in batteries. Solar panels produce direct current, the strength of which depends on the size of the solar panel module and the intensity of the sunlight.
When light hits the surface of the solar cell, electrons gain energy that causes them to move in a certain direction. This creates a stream of electrons that move through the material, resulting in electrical energy.
A grid-connected solar panel system is part of the home’s energy system, which is connected to the public electricity grid.

The power that comes to the house’s solar roof is direct current. In order for the current to be used in the socket, it must be converted to alternating current. This is done using a grid inverter that is placed inside the house near the electricity meter. From the grid inverter, the power flows out into the house’s sockets, mixed with power from the electricity company.
The angle between the sun and the panel can have a great impact on the effect of a solar panel. This is because the sun’s rays have the greatest effect when they hit the panels at an angle as close as possible to what is known as a “perfect” angle. The closer to the perfect angle a panel is placed, the more efficient it will be and the more rays it will absorb and convert into electrical energy.

In Denmark, the optimal angle is 38 degrees to the south to achieve the greatest possible effect.

If the sun shines from an angle other than the optimal angle, it will result in a lower efficiency. This is because the sun’s rays will hit the panels at an angle that is less than optimal. This results in the panels not absorbing as much energy as they otherwise would, resulting in a lower output.

C-Si cells are significantly more sensitive to the sun angle compared to CIGS cells. In cases where the C-Si solar cells lie flat, the effect is around 80%. CIGS cells are of course also affected by the angle of the sun, but they still perform 95% when laid flat. This is because they use two layers of coatings that absorb light from all angles.

Efficiency

Light is the key to efficiency

Our CIGS solar panels can maintain efficiency over many hours every day. This is because our solar panels in reality is light panels, which means they will produce electricity even in cloudy weather, and also during dusk and dawn, as they absorb a wide spectrum of light wavelengths.

CIGS Solar Panel

The CIGS solar panel is often recognised on its slim profile, its flexibility and its low weight. CIGS solar panels are better than conventional solar panels in almost every aspect, when it comes to sustainability efforts and especially durability.

mono- and polycrystalline solar panels (C-SI / poly-Si)

These types of solar panels are what most would consider the conventional type. You often see these on houses and buildings. From time to time, the crystalline solar panels will be mounted on vehicles, however the crystalline solar panels are very fragile and will in many cases break because of the constant vibrations from driving.

CIGS vs. C-Si
