SunOyster Systems demonstrated to Portuguese energy company Galp Energia in Lisbon how its innovative lightweight modules with glass fronts are installed
Halstenbek, Lissabon August 2025. At the invitation of the European Innovation Council (EIC), SunOyster Systems proposed lightweight modules for gas station roofs and was invited to Lisbon by Galp. The lightweight modules with tempered glass fronts are the solution for generating affordable solar power even on roofs with limited load-bearing capacity that cannot support a normal PV system. With Portugal's high levels of solar radiation, they can generate one kilowatt hour of electricity for just 3 euro cents. Gas stations have a high electricity consumption of around 100,000 kWh per year. A 45 kWp solar system can thus generate a cash flow of approximately 100,000 euros over 20 years and save 600 tons of carbon dioxide. This was convincing, and within a short time, the first pilot project was realized, glued directly onto a trapezoidal sheet metal roof.
„Our lightweight modules have a glass front with two major advantages over polymer-coated lightweight modules: their smooth surface makes them more resistant to dirt and gives them optimum rigidity.“ , Carsten Corino, CEO at SunOyster Systems.
Lightweight modules with high efficiency
The training of Portuguese installers and the commissioning of the lightweight photovoltaic modules took place in bright sunshine on a harbor building with a barrel roof and with a view of the famous bridge over the Tagus River. The lightweight modules can demonstrate their high efficiency of almost 21% here.
„Our innovation strategy always aims to find solutions to the specific challenges faced by our customers, and this is a very good example of that.“, says Ana Casaca, Director of Innovation at Galp.
