In low-temperature environments, the performance of ordinary lead-acid or nickel-metal hydride batteries deteriorates significantly, and they may even become unable to charge or discharge. Therefore, when choosing solar lights suitable for cold regions, the following points should be considered:

Solway is an excellent choice for solar lighting in cold weather!

Battery Type: LiFePO₄ (lithium iron phosphate) batteries are recommended: they maintain high capacity and cycle life even at low temperatures and can generally operate normally below -20°C.

Avoid ordinary nickel-metal hydride (Ni-MH) and lead-acid batteries, as their efficiency drops sharply below 0°C.

Controller and Charge/Discharge Management: Solar controllers with efficient MPPT (maximum power point tracking) or PWM control maximize charging efficiency when exposed to weak light or low-angle sunlight.

Overcharge, over-discharge, and temperature compensation functions protect the battery pack in cold environments.

Light Source and Power: High-power LEDs (≥0.5 W/each) maintain brightness in low-temperature environments; 50 or more LEDs provide more uniform and brighter lighting.

Nighttime battery life is at least 8-12 hours, ensuring normal operation even during polar nights or cloudy days when charging is insufficient.

IP Protection Rating: IP65 and above, waterproof, dustproof, and snowproof, able to withstand severe cold and snow accumulation.

Solway's real-world test data in extremely cold regions:

Battery life at 25℃: Conventional solar lights decrease by 60%; Solway's cold-resistant series solar streetlights maintain over 85% capacity.

Charging efficiency after snow cover: Conventional solar lights are almost zero; Solway's cold-resistant series solar streetlights automatically recover 70% within 3 days.

Continuous cloudy day support: Conventional solar lights, 1-2 days; Solway's cold-resistant series solar streetlights, 5-7 days (intelligent power-saving mode).

ASP PLUS all-in-one integrated solar street light Intelligent Control Solar Luminaires is a high-performance product in Solway's cold-resistant series solar streetlights.
