Solar modules are concluding their development towards a freely designable building material. The design of this building material starts with the vision of the overall project. Three steps lead from the central idea to the solar module.
1. The grid defines the shape, size and power of the solar modules
Rectangles, triangles, polygons, circles, curves, cut-outs: the free choice of the solar modules’ geometries is the starting point for the design. The measurements range from 300 x 500 mm to 2500 x 4200 mm. Glass thicknesses of 2-12 mm per pane can be processed. Cost advantages are achieved by using the standard size of 1634 x 986 x 8 mm. The degree of hardening (TVG, ESG) can be chosen freely.
2. The appearance determines the surface of the solar modules
The full spectrum of the material «glass» is available for the design. Structures and finishes of surfaces are possible, along with the targeted use of reflections. Solar glass is the basis of most integrated solar modules, due to its subtle structuring and highest efficiency. This structuring ensures a high light absorption and minimal glare.

3. The character results from the colours and their intensity
Colour: The colour of the solar modules is open. It is possible to design with light pastel tones, as well as with rich earthy tones. Three sources can be used for the choice of colour:
- Megasol colour chart (time and cost-efficient)
- > NCS colour chart (wide colour spectrum)
- Individual colour development (completely open)
High colour intensities (opacity) make the cell structure disappear, keeping the solar secret of the building envelope. Light intensities, on the other hand, allow a technoid impression and performance up to 95% of a conventional solar module (up to 175 Wp/m2).
Black: The classical pinstriped look allows accents with the help of technology. This design option is the most efficient both in terms of performance and costs. By concealing the busbars (cell contacts), discretion can be increased, so that the technology is only visible at second glance. This design option is known by the name of «Full Black».
