Mono PERC, MBB
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.
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.
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.
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.
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.
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.
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.
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.
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.
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).
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.
Maximize limited rooftop space with high-efficiency 500W modules. A typical 5kW system requires only 10 panels (vs 14-16 panels for 350W modules), leaving more roof space for future expansion or aesthetics. Sleek all-black design blends seamlessly with modern architecture.
Reduce installation costs with fewer modules, less racking, and faster deployment. A 100kW commercial system requires only 200 panels (vs 285 panels for 350W modules), saving $8,000-$12,000 in balance-of-system costs. Lower weight reduces structural reinforcement requirements.
Maximize land utilization and energy yield per hectare. A 10MW solar farm requires only 20,000 panels (vs 28,500 panels for 350W modules), reducing installation time by 30% and lowering O&M costs. Superior snow/wind load rating ensures reliability in harsh climates.
