Demax Solar Hybrid Panel PVT Electricity/Hot Water
Demax PVT600M is a high-performance hybrid photovoltaic-thermal solar collector that ingeniously combines photovoltaic power generation and solar thermal collection technologies. Different from traditional standalone solar panels, this product captures both electricity and usable heat from solar radiation simultaneously. During operation, the built-in copper heat exchange pipes continuously absorb the waste heat generated by PV cells while producing hot water, which effectively lowers the operating temperature of solar cells. This optimized design improves the overall electrical efficiency by 8.2% compared with conventional PV modules and avoids power attenuation caused by overheating, achieving dual utilization of solar energy and maximizing energy output per unit area.
Crafted with premium materials including tempered glass, aluminium alloy frame, high-efficiency absorber coating and EPP foam insulation, the collector delivers outstanding durability and thermal performance. It has obtained authoritative Solar Keymark certification (valid until October 31, 2029), and fully complies with DIN EN 12975:2022, ISO 9806:2018, IEC 61215 and IEC 61730 international standards after strict testing by Intertek and TÜV Rheinland. The product features a gross area of 2.83 m² with a peak electrical power of 600 Wmpp. It supports a maximum operating pressure of 600 kPa and a standard stagnation temperature up to 90°C. With excellent environmental adaptability, it passes rigorous tests including ±1000 Pa wind pressure load, 1.2 m hail impact, thermal shock, rain penetration and long-term outdoor exposure, classified as Climate Class B to adapt to various complex outdoor climates worldwide. Water or water-glycol antifreeze fluid can be used as the heat transfer medium, ensuring stable operation even in cold regions.
Flexible in installation, Demax PVT600W is applicable for rooftop, in-roof and facade mounting, with the optimal installation orientation facing due south at a tilt angle of local latitude minus 15 degrees. It is an ideal energy solution for diversified scenarios, covering residential buildings, hotels, schools, factories and other commercial facilities. The system can stably supply on-site electricity, domestic hot water, floor heating and industrial process hot water, helping users reduce electricity and gas consumption, cut energy costs and realize eco-friendly and sustainable energy utilization. With reliable quality and long service life, our PVT collector is a cost-effective choice for global solar energy projects.
