BIPV trend

The European PV market has experienced robust expansion. The year 2018 brought 11GW of new installations in Europe itself and achieved growth of 20% compared to 2017. The forecasts for 2019 are equally optimistic.

In residential areas, the market will benefit greatly from EU regulations for passive housing. In short, the newly constructed buildings would have to meet the strict requirements of energy efficiency.

In reality, the only way to meet these conditions is solar energy. Although already popular, PV will be become the standard. As a result, the integrated systems will gain in importance, which is already noticeable in the countries like the Netherlands, Switzerland, Germany and Sweden.

Eterbright with the advanced thin film, is well positioned to deliver the high-end BIPV products. Eterbright provides a bridge between the industries of architectural design and renewable energy, merging and revolutionizing them so that the future can be both functional and beautiful. While the silicon BIPV is just a compromise, thin film solutions represent real value-added for the architects.

Our CIGS leaves the space to maneuver with the tilt angle, sizing and colors of the modules. The replacement of the traditional construction materials is within the reach.

Installation process

Simplicity and versatility

The ultimate idea of ePower Tiles is to replace the traditional roofing. To achieve this, the installation should be kept just as simple. This is the case for the Eterbright system.

Due to the inherent properties of CIGS, our ePower Tiles exhibit low sensitivity to such factors as imperfect tilt angle and roof orientation or shading risk. Versatility becomes crucial under the European conditions.

ePower Tile system design

Example of a 4.5 kWp system

Parallel string

To meet the voltage conditions of the inverter, the tiles are first switched into a parallel chain. The maximum current is 12A.

Series string

In the next step, the parallel strings are connected in series so that the voltage remains at about 600V.


The annual yield of such a plant would reach 4500 kWh in northern Europe and up to 6000 kWh in the south. This amount is enough for the average household need. In the coming years, the energy storage systems and the EV would only increase the utility value of the installation.


The Eterbright ePower Tile system complies with EU safety standards, which is reflected in the required certification of the product. The system provides full protection against rain, wind and snow.
