Model TP156-595M/MB-9 | Mono PERC | 156 Half-Cell 182×182 mm | Monofacial | 1500V System Voltage
The Topsky Energy TP156-595M/MB-9 solar panel is a powerful 595 Wp mono PERC half-cell module designed for high efficiency and long term reliability in commercial and utility scale systems. This monocrystalline solar panel combines advanced 182×182 mm half-cut cells, low resistance circuitry, and high transmission coated glass to deliver strong output even in low light conditions. With panel efficiency up to 21.6% and a maximum system voltage of 1500 V, it supports large string designs and optimized balance of system costs. The module uses 156 half cells and a robust 3.2 mm tempered glass front layer with anti reflection coating for stable performance in harsh environments. A 12 year product warranty and linear performance warranty, offering 90% power at year 12 and 83.1% at year 25, ensure dependable energy yield over the full lifetime of your project. Manufactured by Topsky Energy in China, this panel suits ground mount, rooftop, and industrial installations that need bankable performance and predictable returns.
High power density for large projects: Up to 595 Wp output and efficiency up to 21.6% allow more power per string and reduced array footprint. This helps unlock better project economics on constrained roofs and ground sites.
Optimized half-cell mono PERC design: Half cut 182 mm mono cells reduce resistive losses and improve energy harvest across a full day. The PERC structure increases light capture, delivering stronger performance under real world irradiance.
Reliable long term performance: A total degradation rate of only 0.68% per year supports 90% power after 12 years and 83.1% after 25 years. The linear performance warranty and 12 year product warranty protect long term investment value.
Engineered for harsh environments: The module is certified for high wind and snow loads and resists potential induced degradation in demanding sites. Anti reflection tempered glass, IP68 junction box, and durable EVA encapsulant increase field reliability.
Flexible system integration: With a 1500 V DC system voltage rating and 25 A series fuse rating, the panel works with modern string inverters and central inverters. It is suitable for ground mount arrays, trackers, and large roof systems that require high string lengths.
This Topsky Energy TP156-595M/MB-9 monocrystalline half cell solar panel converts sunlight into usable DC electricity through high efficiency mono PERC photovoltaic cells. Each of the 156 half cut 182×182 mm cells is designed to capture light on the front surface and channel electrons through low resistance busbars, boosting output in a compact footprint. When irradiance hits the anti reflection coated tempered glass, more light reaches the PERC cell structure, which enhances absorption and reduces recombination losses. The resulting DC power is collected through optimized cell strings, routed through the junction box, and delivered to your inverter. A 1500 V system rating allows longer strings, helping to reduce cable runs and balance of system cost. Combined with low annual degradation and strong warranty coverage, the panel is engineered to provide stable energy generation for grid tied systems, commercial rooftops, and large solar parks over decades of operation.
Half-cell mono PERC energy conversion: The module uses half cut monocrystalline PERC cells arranged in two main sections on the panel surface. Each half cell operates at lower current, which reduces resistive losses in the conductors and increases overall efficiency. The PERC layer on the rear of each cell reflects unabsorbed light back into the silicon, improving energy capture especially in low and diffuse light conditions.
Low light and temperature optimized design: Advanced glass and cell surface texturing are used to minimize reflection and maintain strong output on cloudy days or during early morning and late afternoon. Temperature coefficients of -0.35% per °C for Pmax and -0.275% per °C for Voc help limit performance loss as module temperature rises. An operating temperature range from -40°C to 85°C supports energy production in both hot and cold climates.
Robust mechanical and electrical integration: Power from each cell string is combined in an IP68 rated junction box with high quality connectors and 4.0 mm² cables for reliable DC transmission. The 3.2 mm tempered, low iron glass with anti reflection coating protects the cells while allowing high light transmission. Anodized aluminium framing and EVA encapsulation hold the laminate together, allowing the module to withstand wind and snow loads and maintain performance throughout its 25 year warranty period.
