Upsolar UP-M450MH 450W PERC Monocrystalline Solar Panel
Model UP-M450MH (60M10) | PERC Monocrystalline | 120 Half-Cell | Monofacial | 1500V System Voltage
Product Overview
The Upsolar UP-M450MH 450W PERC monocrystalline solar panel delivers high power density in a compact footprint, making it ideal for residential and commercial rooftops where space is limited. With a module efficiency of 20.8%, this panel converts more sunlight into usable energy, helping systems reach target production with fewer modules overall. The advanced PERC cell architecture and 120 half-cut monocrystalline cells support reliable output across a wide range of conditions, from hot summer days to colder climates. A maximum power rating of 450 Wp, combined with tight 0 to +3% positive power tolerance, ensures dependable performance right out of the box. Long term energy yield is supported by a 12 year product warranty and a power warranty that guarantees 93.05% output at 10 years and 84.80% at 25 years. Robust mechanical design, including a 3.2 mm tempered glass front and anodized aluminium frame, is engineered for durability and stable operation throughout the panel lifetime.
Key Benefits
High power density for tight spaces: A 450 Wp output and 20.8% efficiency allow strong production on constrained roof areas and commercial arrays.
Reliable long term performance: The linear power warranty supports 93.05% output at 10 years and 84.80% at 25 years, helping secure long term yield forecasts.
Advanced PERC monocrystalline cells: PERC cell technology increases light absorption and efficiency while the monocrystalline structure enhances performance and aesthetics.
Strong mechanical build quality: Tempered glass with anti reflection coating, EVA encapsulation and an anodized aluminium frame help protect cells against weather and mechanical stress.
Flexible system integration: A 1500 V maximum system voltage, MC4 connectors, and IP68 junction box simplify design with modern inverters and balance of system components.
How It Works
This Upsolar PERC monocrystalline solar panel converts sunlight into direct current electricity through advanced photovoltaic cells. Each of the 120 half cut monocrystalline cells is designed to capture incoming light efficiently and minimise resistive losses across the cell surface. When the module is exposed to sunlight, photons strike the silicon lattice and create electron hole pairs, which are then driven by the internal electric field to generate current. The panel delivers up to 450 Wp at standard test conditions, with a Vmpp of 34.35 V and Impp of 13.1 A. Power is routed through an IP68 junction box with three bypass diodes and then carried by 4 mm² DC cables terminated in MC4 connectors. Once connected into a string, the combined DC power is fed to a compatible inverter, where it is converted into AC electricity for site loads or export to the grid. Throughout this process, the high efficiency cell design and careful thermal management maintain stable production over the wide operating temperature range from minus 40 to 90 degrees Celsius.
PERC monocrystalline cell conversion: PERC technology adds a passivated rear surface, which reflects unabsorbed light back into the cell for a second absorption opportunity. This design increases energy capture compared with conventional cells and supports the panel efficiency range from 20.57% to 21.49% across the series.
Half cut 120 cell layout: The 182 x 91 mm cells are cut into halves and arranged as 120 cells to reduce current and resistive losses. This layout supports better shade tolerance and slightly lowers operating temperature, which helps preserve power output over time.
Thermal and electrical optimisation: Temperature coefficients of minus 0.35 percent per degree Celsius for Pmax and minus 0.27 percent per degree Celsius for Voc limit performance loss as the panel warms up. The low positive power tolerance, 0 to plus 3 percent, ensures that installed modules meet or exceed the nameplate rating, which helps streamline array design and performance modelling.
