Model SS8-72HD-550M | Mono PERC (M10) | 144 Half-Cell | Monofacial | 1500V System Voltage
The SolarSpace SS8-72HD-550M 550W Mono PERC monofacial solar panel is engineered for reliable high output in modern solar projects. This module combines advanced M10 monocrystalline PERC cells with half-cut and multi-busbar design to deliver strong performance at 550 watts of maximum power. High module efficiency up to 21.29 percent allows more energy production from limited roof or ground space. This panel suits residential, commercial, and utility applications that demand stable power, long life, and strong warranty coverage. A 1500 volt system rating supports large string designs and optimized balance of system costs. Robust construction with anti-reflection coated glass and a durable anodized aluminum frame helps ensure dependable operation in challenging weather. Thoughtful electrical and mechanical specifications make this module easy to integrate with mainstream inverters and mounting systems. The SS8-72HD-550M offers an attractive balance of performance, efficiency, and long term energy yield for professional installers and project owners.
High power density for compact arrays: With 550 watt output and up to 21.29 percent efficiency, fewer modules are needed for a given system size. This saves racking, wiring, and labor while maximizing production on constrained roofs and carports.
Reliable energy yield over time: A low degradation rate of about 0.5 percent per year supports strong long term performance. After 30 years, the module retains around 84.95 percent of original power output under standard conditions.
Optimized cell and circuit design: Half-cut M10 Mono PERC cells reduce resistive losses and improve shade behavior. Multi-busbar technology enhances current collection and lowers the risk of microcracks affecting power production.
Robust construction for harsh sites: Tempered anti-reflection glass and an anodized aluminum frame withstand high mechanical loads. The panel design supports up to 5400 pascal front load and 2400 pascal rear load when installed correctly.
Installer friendly electrical characteristics: A maximum power voltage of about 41.97 volts and current of 13.1 amps simplifies string design. The 1500 volt system rating allows longer strings and reduced combiner costs in many projects.
Wide operating temperature range: The module operates from minus 40 to plus 85 degrees Celsius. Carefully managed temperature coefficients help maintain stable performance in hot climates and cold regions.
The SolarSpace SS8-72HD-550M converts sunlight into usable electrical energy using high efficiency monocrystalline PERC cells. When sunlight strikes the cell surface, photons are absorbed and generate charge carriers inside the silicon lattice. These charges are separated by the cell’s internal electric field and directed through a circuit, creating direct current power. Half-cut cell architecture reduces the current in each cell string, lowering resistive losses and helping maintain output under partial shade. Multi-busbar conductors collect current from more points on each cell, increasing reliability and power density. The module’s glass and encapsulation layers protect the cells from moisture and mechanical stress while allowing strong light transmission. Electrical energy then flows through the junction box and cables to an inverter, where it is converted into alternating current suitable for homes, businesses, and grid export. Stable temperature behavior and low annual degradation support consistent production over the system lifetime.
Mono PERC cell conversion: Each M10 monocrystalline PERC cell uses a passivated rear surface to capture more light. This structure reflects unabsorbed photons back into the silicon, raising efficiency compared with standard cells.
Half-cut and multi-busbar layout: The 144 half cells are arranged to split the panel into parallel strings that limit loss from local shading. Multi-busbar fingers shorten current paths, which reduces resistance and improves energy harvest.
Thermal and environmental stability: Optimized temperature coefficients control power loss as cell temperatures rise during operation. Durable encapsulation, coated glass, and sealed junction boxes protect the internal circuitry from moisture, dust, and corrosion.
