Solar Street Light Energy Storage Optimization
Facing chronic failures of lead-acid batteries in -30°C winters, GreenWay Renewable Energy sought a decade-long maintenance-free solution for Scandinavia’s solar streetlights. Our tri-layer energy architecture combined LiFePO4 batteries as primary storage—delivering 98% depth of discharge and 20,000 cycles. An AI controller with self-heating function automatically activated backup power during polar nights, overcoming electrolyte crystallization risks. Deployed across 12,000 units in Nordic cities, it eliminated manual maintenance while achieving 62% lifecycle cost reduction, setting a new standard for extreme-climate renewable infrastructure.
