Battery Technology | Off-grid systems needing cost-effective storage | Lead-Acid: • Industry: 3-year lifespan (IEC 60896) • ▲ Our Base: 4-year lifespan (IEC 60896) • ▲ Our Advanced: 5-year lifespan (UL 2580) | Lower upfront cost, widely compatible with legacy systems. | Requires periodic maintenance; heavier than lithium-ion alternatives. |
Solar Panel Efficiency | High-efficiency energy capture in sunny regions | Monocrystalline Silicon: • Industry: 18% efficiency (IEC 61215) • ▲ Our Base: 20% efficiency (TÜV认证) • ▲ Our Advanced: 22% efficiency (TÜV认证) | Maximizes energy output per panel area; durable under high temperatures. | Slightly higher upfront cost than polycrystalline panels. |
System Power Capacity | Large residential/commercial off-grid setups | • Our Base: 3kW (IEC 61727) • ▲ Our Advanced: 5kW (IEC 61727) | Scalable to meet diverse energy demands; supports heavy loads like air conditioners. | Larger systems require more complex installation and space. |
Controller Technology | Maximizing energy harvesting in variable sunlight | MPPT (Our Base/Advanced): 99% efficiency (IEC 61672) Industry Standard: PWM controllers (85% efficiency) | Optimizes energy conversion in low-light conditions; reduces power loss. | Slightly higher cost than PWM controllers. |
Mounting Type | Areas with limited rooftop space | Ground Mounting: 15° tilt adjustment (ISO 6948) Industry Standard: Rooftop mounting | Flexible installation in open fields or uneven terrain. | Requires more ground space; potential exposure to environmental damage. |
Warranty Period | Long-term investment protection | • Industry: 2 years • ▲ Our Base/Advanced: 3 years (IEC 61727) • ▲ Advanced: Optional 5-year extension (TÜV认证) | Enhanced customer assurance for critical components like inverters. | Extended warranties may incur additional costs. |
Noise Level | Residential areas needing quiet operation | • Industry: 50 dBA (IEC 61404) • ▲ Our Base: 45 dBA (ISO 1996) • ▲ Our Advanced: 40 dBA (IEC 61404) | Quieter than a refrigerator hum (43 dBA), ideal for bedrooms/offices. | Advanced models may use premium materials, increasing cost. |
