Solarwatt's Lightweight Modules Revitalize Older Roofs on Farms
Solarwatt, a German manufacturer, has developed a solution for older roofs on agricultural operations. Their PV lightweight modules, weighing only 5 kg per square meter, could be ideal for roofs with limited load-bearing capacity.
These modules, featuring tempered glass on the front, are almost as efficient as high-performance modules. They can generate power at under 5 cents per kWh, making them cost-effective.
For older thatched roofs lacking load reserve, these lightweight modules offer a viable solution. They can have a payback time of 5 years with high self-consumption, making them a sustainable investment. A 45 kWp solar plant, for instance, can generate a cash flow of 100,000 euros over 20 years and save 600 tonnes of carbon dioxide.
Solarwatt's PV lightweight modules provide a practical solution for older roofs on agricultural operations. They are efficient, cost-effective, and can significantly reduce carbon footprint. With a potential payback time of 5 years, they offer a compelling case for investment.
