Upsolar UP-M445MH 445W PERC Monocrystalline Solar Panel
Model UP-M445MH (60M10) | PERC Monocrystalline | 120 Half-Cut Cells | Monofacial | 1500V System Voltage
Product Overview
The Upsolar UP-M445MH 445W PERC monocrystalline solar panel is designed for high efficiency projects where space and reliability matter. With advanced PERC cell technology and a monofacial 120 half-cut cell layout, this module delivers strong output even under challenging site conditions. The panel efficiency of 20.57 percent helps more energy be generated from limited roof or ground areas. A robust anodized aluminium frame and 3.2 mm tempered glass with anti-reflection coating provide dependable durability. The module suits residential, commercial, and light industrial systems that demand consistent production and long service life. Installers and system designers benefit from its balanced electrical ratings, including a maximum system voltage of 1500 volts, which supports modern high string design. Whether used in new grid-tied arrays or for system upgrades, this module offers a reliable balance of performance and long term value.
Key Benefits
High power density: The 445 watt output with 20.57 percent efficiency allows more energy generation from compact mounting areas.
Reliable long term performance: The linear power warranty ensures 93.05 percent output at year ten and 84.80 percent at year twenty five.
Durable mechanical design: An anodized aluminium frame, EVA encapsulant, and tempered glass help the module withstand harsh weather conditions.
Optimized electrical safety: The IP68 junction box with three bypass diodes and MC4 connectors supports secure, low loss string connections.
Flexible system integration: A maximum system voltage of 1500 volts and 20 amp series fuse rating suit modern residential and commercial arrays.
Proven Upsolar quality: Backed by a twelve year product warranty from Upsolar Global Co., Ltd., a specialist module manufacturer from Hong Kong.
How It Works
This Upsolar monocrystalline PERC panel converts sunlight into usable direct current electricity through 120 precision engineered solar cells. Each M10 cell is divided into half cut segments, which reduces internal resistance and helps efficiency be increased under real operating conditions. When light hits the anti reflection coated tempered glass, more photons reach the PERC cell surface and rear structure. The generated current is collected by fine busbars and carried through the EVA encapsulant to the laminated cell strings. From there, power flows into the IP68 junction box, where three bypass diodes protect performance under partial shading. Standard MC4 connectors and 4 mm2 cables then deliver energy safely to your inverter, where it is converted into alternating current power for on site consumption or export to the grid.
PERC monocrystalline cell conversion: The panel uses high efficiency monocrystalline PERC cells that enhance light absorption and electron collection. A passivated rear surface reflects unused light back into the cell, improving conversion efficiency without needing additional area.
Half cut 120 cell architecture: Each of the 60 full cells is laser cut into two halves to create 120 smaller cells. This configuration lowers resistive losses, reduces operating temperatures, and helps power output remain more stable across the module.
Junction box, cabling, and system integration: Inside the IP68 junction box, three bypass diodes allow current to flow around shaded or weak cell strings, limiting mismatch losses. Factory fitted MC4 connectors and 4 mm2 cables enable quick, low resistance string assembly and straightforward integration with compatible inverters.
