Product Overview

The GUANGXI LS-M500 Monocrystalline Solar Module represents the pinnacle of photovoltaic technology, delivering 500W of clean energy from a single panel. Built with premium-grade monocrystalline PERC cells achieving 22.8% conversion efficiency, the LS-M500 generates 15-20% more electricity per square meter compared to conventional polycrystalline modules.

Engineered for extreme durability, the LS-M500 withstands harsh environmental conditions from -40°C Arctic winters to +85°C desert summers. The reinforced aluminum frame supports up to 5400Pa snow load and 2400Pa wind load, meeting the most stringent building codes worldwide. IP68-rated junction box ensures complete protection against dust and water ingress, even during heavy rain or flooding.

Backed by an industry-leading 25-year linear performance warranty guaranteeing 84.8% power output after 25 years, the LS-M500 provides decades of reliable energy generation. With only 2% first-year degradation and 0.55% annual degradation thereafter, your investment maintains its value far longer than standard modules with 0.7-0.8% annual degradation rates.

Product Highlights

🔬

High-Efficiency PERC Technology

Passivated Emitter and Rear Cell (PERC) technology increases light absorption and reduces electron recombination, achieving 22.8% cell efficiency. Generates 15-20% more power per square meter than conventional cells, maximizing rooftop utilization.

🌡️

Superior Temperature Coefficient

Industry-leading -0.34%/°C temperature coefficient means only 0.34% power loss per degree above 25°C. In hot climates (40°C ambient), the LS-M500 generates 5-8% more power than modules with -0.40%/°C coefficients, translating to $200-$400 extra revenue over 25 years.

🌙

Excellent Low-Light Performance

Advanced cell structure captures diffuse light during cloudy days, early mornings, and late afternoons. Maintains 95%+ efficiency at 200W/m² irradiance (typical overcast conditions), ensuring consistent energy production even in less-than-ideal weather.

💎

Anti-PID Technology

Potential-Induced Degradation (PID) resistance ensures stable long-term performance in high-voltage systems. Special cell treatment and encapsulation materials prevent power loss caused by voltage stress, maintaining 99%+ output even after 25 years in harsh environments.

🔥

Hot-Spot Free Design

Multi-busbar (MBB) technology with 9 busbars distributes current evenly across cells, eliminating hot-spots that cause premature failure. If one cell is shaded, bypass diodes reroute current to maintain 66% of module output instead of complete shutdown.

🏔️

Extreme Weather Resilience

Certified for 5400Pa snow load (equivalent to 550kg/m² or 2 feet of wet snow) and 2400Pa wind load (Category 4 hurricane winds up to 240km/h). Operates reliably from -40°C to +85°C, covering 99% of global climate zones including Arctic, desert, and tropical regions.

Technical Advantages

🏆 Half-Cut Cell Technology

132 half-cut cells (vs 66 full cells) reduce resistive losses by 75%, increasing power output by 5-10W. Lower operating current reduces heat generation, extending module lifespan and improving reliability. If one half is shaded, the other half continues generating power independently.

⚙️ Multi-Busbar (MBB) Design

9 ultra-thin busbars (vs traditional 3-5 busbars) reduce shading losses by 30% and improve current collection efficiency. Narrower busbars mean more active cell area exposed to sunlight. Enhanced redundancy—if one busbar fails, the other 8 maintain 89% of output.

💰 Lower LCOE (Levelized Cost of Energy)

Higher efficiency + lower degradation = more kWh generated over 25 years. The LS-M500 produces 12,500-15,000 kWh per module over its lifetime (depending on location), reducing LCOE to $0.03-$0.05/kWh—30% lower than standard modules. Faster payback period (5-7 years vs 8-10 years).

🔄 Bifacial-Ready Design

While the LS-M500 is a monofacial module, its advanced cell structure is compatible with bifacial technology. Future LS-M500B bifacial variant will capture reflected light from ground surfaces (albedo), increasing total energy yield by 10-25% depending on installation height and ground reflectivity.

Frequently Asked Questions

Q: What is the difference between monocrystalline and polycrystalline solar panels?
A: Monocrystalline panels (like the LS-M500) are made from single-crystal silicon, offering 18-22% efficiency, better low-light performance, and longer lifespan (25+ years). Polycrystalline panels use multi-crystal silicon, achieving 15-17% efficiency and lower cost but with faster degradation. Monocrystalline panels generate 15-20% more electricity per square meter, making them ideal for space-constrained rooftops. The LS-M500's 21.3% efficiency is among the highest in the industry.
Q: How much electricity can one LS-M500 panel generate per year?
A: Annual energy generation depends on location, tilt angle, and shading. In optimal conditions (e.g., Southern California, 30° tilt, no shading), one LS-M500 generates approximately 750-850 kWh/year. In moderate climates (e.g., Germany, UK), expect 500-650 kWh/year. Over 25 years, accounting for 0.55% annual degradation, a single panel produces 12,500-15,000 kWh total—enough to power a refrigerator for 40+ years or an LED bulb continuously for 1,400 years.
Q: Can the LS-M500 withstand extreme weather like hurricanes and snowstorms?
A: Absolutely. The LS-M500 is certified for 5400Pa snow load (equivalent to 550kg/m² or 2 feet of wet snow) and 2400Pa wind load (Category 4 hurricane winds up to 240km/h). The reinforced 35mm aluminum frame and 3.2mm tempered glass provide exceptional structural integrity. The module has survived real-world testing in Australian cyclones, Canadian blizzards, and Texas ice storms without damage. Additionally, it's certified for 25mm hailstone impact at 23m/s (IEC 61215).
Q: What happens if one panel is shaded or fails?
A: The LS-M500's half-cut cell design with 3 bypass diodes minimizes shading losses. If one-third of the panel is shaded, the other two-thirds continue generating power at full capacity—maintaining 66% of total output. In series-connected strings, one shaded panel reduces string output by only 33% (vs 100% loss in traditional full-cell designs). If a panel completely fails, the bypass diodes allow current to flow around it, maintaining 90%+ of string output. We recommend microinverters or power optimizers for installations with significant shading.
Q: How does the 25-year warranty work?
A: GUANGXI offers two warranties: (1) 12-year product warranty covering materials, workmanship, and manufacturing defects—we'll repair or replace defective modules at no cost. (2) 25-year linear performance warranty guaranteeing 98% output in Year 1, then 0.55% annual degradation, reaching 84.8% output in Year 25. If a module underperforms, we'll provide replacement modules to compensate for the power deficit. Both warranties are transferable to new property owners, adding resale value to your home.
Q: Are the panels compatible with all inverter brands?
A: Yes! The LS-M500 uses standard electrical specifications (49.5V Voc, 41.8V Vmp) compatible with all major inverter brands including GUANGXI, Huawei, SMA, Fronius, SolarEdge, Enphase, and APsystems. For string inverters, typical configurations are 8-12 modules per string (depending on inverter MPPT voltage range). For microinverters, use 1-4 modules per microinverter (check manufacturer specs). The MC4-compatible connectors ensure plug-and-play installation with any standard solar cable.
