Product description
The SunStyle Building-Integrated Photovoltaic (BIPV) Solar Roofing module is designed with active shingles that integrate high-efficiency solar cells, encapsulated between a durable front glass superstrate and a protective substrate. The assembly incorporates cell connectors, string connectors, a junction box, bypass diodes, cables, and module connectors, all meticulously bonded using high-performance adhesives and potting materials. This construction ensures superior structural integrity, weather resistance, and long-term reliability, making it a seamless and efficient roofing solution.
Interpretation
The results of the life cycle assessment indicate that the raw material and manufacturing process phase have the most significant impact on the environmental performance of the products under study. More than 73% of the overall global warming potential is attributed to the raw materials stage with manufacturing process contributing 16% to the overall global warming potential of the product. Additionally, Manufacturers shall not make claims based on an industry-average EPD which leads the market to believe the industry-average is representative of manufacturer-specific or product- specific results.
LCIA results are relative expressions and do not predict impacts on category endpoints, the exceeding of thresholds, safety margins or risks. EPDs are comparable only when they follow the same PCR, functional unit and system boundary. The full EPD (PDF) contains the methodology, scenario assumptions and verification statement.
