Model SM12-580~605W(120) | PERC Monocrystalline | 120 Half-Cell | Monofacial | 1500V System Voltage
The SunMaster SM12-585 585W PERC Monocrystalline Solar Panel delivers high power density in a robust utility scale format, making it ideal for commercial and industrial solar projects. This monocrystalline PERC half cell module combines a 585 Wp peak output with panel efficiency up to 21.38 percent, so more energy is generated from each square meter of roof or ground space. The module sits within a durable anodized aluminium frame and uses 3.2 millimeter tempered glass with anti reflection coating for reliable long term performance. With a maximum system voltage of up to 1500 volts and optimized operating characteristics at both STC and NOCT, the SunMaster 585 panel suits large string inverters and high voltage arrays. The design has been engineered for stable energy yield under high temperatures, low light conditions, and challenging outdoor environments. This panel is a strong option where dependable generation, compact dimensions, and bankable warranties are required.
High power density for large arrays: Each module delivers up to 585 Wp at STC, allowing higher system power from fewer panels and faster installation on commercial rooftops and ground mount sites.
Excellent efficiency range: Module efficiency ranges from 20.49 to 21.38 percent, so available roof space is used more effectively and balance of system costs can be reduced over the project lifetime.
Optimized PERC half cell design: The 120 monocrystalline PERC half cells improve shade tolerance and reduce internal resistive losses, which supports higher energy yields in real operating conditions.
Stable performance in heat: A low nominal operating cell temperature of 43 degrees Celsius plus favorable temperature coefficients help maintain output on hot roofs and in warm climates throughout the year.
Robust build for demanding sites: An anodized aluminium frame, tempered front glass with anti reflection coating, and IP68 junction box offer long term reliability on exposed industrial and utility installations.
Bankable long term protection: A 15 year material and technology warranty is combined with a 30 year linear power output warranty, supporting strong project bankability and stable long term returns.
This SunMaster 585 solar panel converts sunlight into direct current electricity using advanced monocrystalline PERC solar cells wired in a half cell layout. When sunlight hits the 210 by 105 millimeter cells, photons are absorbed and release electrons, which then move through the cell structure to create usable electrical current. The PERC architecture improves light capture and reduces losses at the rear of each cell, while the anti reflective glass helps more light reach the active silicon layer. The panel operates at a maximum power voltage of about 34.1 volts and current of about 17.16 amps at standard test conditions. That DC power is then routed through MC4 compatible connectors and 4 square millimeter solar cables to a string inverter or hybrid inverter. The inverter converts the panel’s DC output into AC power for on site loads or export to the grid. Performance remains reliable within an operating temperature range from minus 40 to plus 85 degrees Celsius, so energy generation is maintained in a wide variety of climates and seasons.
Monocrystalline PERC energy conversion: The panel uses high quality monocrystalline PERC cells that absorb incoming light and convert it into electrical energy with high efficiency. The passivated emitter rear contact structure captures additional light reflected inside the cell, which increases current and boosts the overall module output.
Half cell and multi busbar layout: Each full cell is divided into two half cells, which reduces internal resistance and limits power loss under partial shading. Multi busbar collection fingers shorten the path for electrons and lower series resistance, so the panel maintains stronger power delivery along the entire length of the string.
Thermal and environmental management: A nominal operating cell temperature of 43 degrees plus or minus 2 degrees Celsius and low temperature coefficients help control performance under heat. The tempered glass, IP68 junction box, and anodized aluminium frame shield the cells and connections from moisture, dust, and mechanical stress, so the module delivers consistent energy output over decades.
