Recently, persistent high temperatures above 40°C have subjected PV modules to severe challenges. In high-temperature and high-humidity regions such as Africa, the Middle East, and Southeast Asia heatwaves strike without mercy targeting the vulnerable spots of components…While traditional photovoltaic modules suffer from frequent hot spots and drastic efficiency drops like stubborn “boils”.The Q-SUN MERCURY series, with its outstanding performance, proves to be the ideal solution for high-temperature environments:
- Ultra-Low Temperature Coefficient (-0.30%/°C) Ensures Stable Power Generation in High Temperatures
The Q-SUN MERCURY series features an optimized temperature coefficient of -0.30%/°C, significantly better than PERC modules (-0.40%/°C). At a surface temperature of 55°C, its power degradation is reduced by over 2% compared to PERC modules. In extreme environments like African deserts where temperatures exceed 50°C, daily power generation can increase by 3.5%, equivalent to an additional 1,200 kWh per MW annually
- Bifaciality Up to 85%, Rear-Side Power Generation Compensates for High-Temperature Losses
With a symmetrical front/rear design, the Q-SUN MERCURY series achieves 85% bifaciality. When high temperatures reduce front-side efficiency, the rear side absorbs 20% of ground-reflected light, significantly boosting overall power output. In high-reflectance environments like Middle Eastern deserts, bifacial synergy effectively offsets efficiency losses caused by heat
- Enhanced Encapsulation Technology for Superior Weather Resistance
1.Operating temperature range of -40°C to 85°C: Using anti-PID film and reinforced frames, the annual power degradation remains below 0.4% under dual 85 test conditions (85°C temperature / 85% humidity).
(Double 85 PID Testing)
2.Advanced interconnection technology: Multi-busbar (MBB) soldering optimizes the ribbon-cell connection structure, reducing series resistance and minimizing hot spot risks.Building upon this foundationa customized high-effciency 710W module tailored for high-temperature regions (e.g., Pakistan) has been upgraded to SMBB with a 24BB design further improve hot-spot resistance and high-temperature resistance.
3.30-year long-term warranty: Even in harsh high-temperature and high-humidity environments, a 30-year power output guarantee is provided.
With a peak power of 720W, conversion efficiency above 23.2%, and exceptional weather resistance, the Q-SUN MERCURY series keeps PV plants in high-temperature and high-humidity environments free from “premature aging” concerns, ensuring stable performance under extreme weather conditions.
