Blue solar panels

There is a reason why most solar panels are blue. The simplest manufacturing process creates a blue solar panel. Choose blue polycrystalline solar panels when good performance is exactly what you need.

Blue-coloured solar panels for businesses

The standard, most commonly used solar panels consist of a substrate, solar cells and a sheet of glass.


The solar cells are, in most cases, crystalline. These can be poly or monocrystalline cells. Both are made of silicon, which is commonly found in sand. This silicon is melted and cooled in a mould. A polycrystalline solar cell consists of several interlaced crystals, which makes the panel appear to have spots. Polycrystalline cells are blue in colour. In a monocrystalline panel, the crystals are affected during solidification so that they all align in the same direction. This creates a plain, dark blue to black panel.

Application of a polycrystalline solar panel


Polycrystalline solar panels are the standard solution for large roofs and large fields of panels. As the manufacturing process is the simplest, they are the least expensive panels. However, the quality is not compromised and the yield does not have to be lower either. Blue solar panels often have a bare, light-coloured aluminium frame, which contrasts with the blue solar cells. With a completely black all-black monocrystalline solar panel, the aluminium frame is black anodised, which looks more pleasing. A blue solar panel can be fitted with a blue or black frame.

Disadvantages and advantages of blue polycrystalline solar panels


Due to the solidification of multiple poly solar cells in a cast, a blue solar panel often has white dots or lines. A monocrystalline solar panel can be produced uniformly, without white lines or dots. This is an extra step in production which produces a neater panel and higher efficiency. The advantage of the lighter blue panels is that they heat up less due to the sun, PV panels have a higher efficiency at lower temperatures.

Yield and efficiency blue PV panels


Solar panels generate electricity not only in direct sunlight, but also in diffuse light. Diffuse light is indirect light, which, for example, we see in light, cloudy conditions. Poly solar cells yield more in diffuse light, mono solar cells in direct light. Both forms of sunlight occur, so this hardly matters for the yield. Monocrystalline panels can provide up to 10% higher yields, due to the neater processing of the cells into a solar panel.

FAQ – Frequently asked questions

What are the advantages of blue solar modules?

Solar panels in blue are the thought of as ‘standard’ panels. The simple production process gives you the best price/quality ratio. In addition, the lighter blue heats up less than black PV panels, which keeps the yield high in summer when there is direct sunlight.

What is the efficiency of blue solar panels?

The manufacturing process of a blue solar panel is the simplest, making them the least expensive solar panels. The efficiency of a solar panel depends mainly on its quality – a black monocrystalline solar panel can theoretically achieve a 10% higher level of efficiency than a blue polycrystalline panel.
