Old solar panels on aged roofs now function with these innovative PV modules
In a groundbreaking development, SunOyster Systems, a German startup, has proposed a revolutionary solution to generate solar power – the PV lightweight modules. These innovative modules are designed to harness solar energy from load-bearing limited roofs, making them ideal for older roofs on agricultural operations and even petrol stations.
Petrol stations, with their high electricity consumption of around 100,000 kWh per year, could significantly benefit from this lightweight and efficient technology. In high sunlight, a kilowatt hour of electricity can be generated for only 3 Euro cents with these modules, making solar power more affordable than ever.
The unique lightweight nature of these modules, weighing just 5 kg per square meter, allows them to be a viable option for roofs that cannot support the python basics of conventional PV systems. Interestingly, these lightweight modules are uniquely lightweight in Germany, setting a new standard in the industry.
The front of the PV lightweight modules is made of tempered glass, ensuring durability and safety. Germany's Solarwatt manufactures these modules, equipping them with a front part made of reinforced glass, further enhancing their strength and reliability.
The benefits of these lightweight modules extend beyond just affordability and lightweight construction. A 45 kWp solar plant using these modules can generate a cash flow of 100,000 euros over 20 years and save 600 tonnes of CO2. A high self-consumption of solar power generated by these modules can result in a payback time of 5 years on the overall project, with external capital investment potentially reducing the amortization of equity capital to one year.
Comparatively, the PV lightweight modules have almost the same efficiency as conventional PV systems. However, the specific details about switching a photovoltaic system to self-consumption for optimal benefits are not provided in the given text.
SunOyster Systems' innovative approach has not gone unnoticed. The company was invited to Lisbon as one of the winners of a start-up competition by Galp, a Portuguese energy company, further validating the potential of these lightweight PV modules.
This development marks a significant step towards a more sustainable and affordable energy future, demonstrating the potential of innovative technology to revolutionise the energy landscape.
