Zero trenching. Grid-independent operation. Engineered for a 20-year service life in the most demanding global environments.
Selecting a reliable commercial solar street light manufacturer is critical for large-scale infrastructure, municipal developments, and highway lighting contracts. Solar Lighting International, Inc. designs and manufactures industrial-grade solar street lights built for exceptional longevity, zero energy costs, and minimal total cost of ownership. Powered by high-efficiency monocrystalline solar panels, premium LiFePO4 batteries, and Philips Lumileds 5050 LED chips, our systems deliver continuous, high-lumen illumination without grid connection.
Delivering lumen packages from 6,600 lm up to 22,200 lm per fixture — expandable to 44,400 lm for wide multi-lane highways and major arterial thoroughfares.
Advanced Lithium Iron Phosphate battery chemistry provides over 7 years of operational lifespan, superior thermal stability, and up to 3+ days of autonomous backup during cloudy weather.
Heavy-duty aluminum and steel light poles engineered to withstand extreme weather and wind loads up to 180 mph. Powder-coated to resist marine corrosion and saltwater environments.
Integrated Maximum Power Point Tracking (MPPT) intelligent charge controllers maximize solar harvest efficiency and enable multi-stage adaptive dimming schedules.
Precision directional LED optics direct light precisely onto the target roadway surface, eliminating wasteful light pollution, glare, and sky glow in accordance with IDA standards.
Available with optional IoT smart city control modules for remote system monitoring, automated diagnostic reports, and central management software integration.

Every commercial solar lighting project engineered by Solar Lighting International includes custom photometric rendering and IES light distribution modeling. Our experienced team of sales engineers assists EPC contractors, municipal procurement officers, and project developers in matching local wind load specifications, winter insolation profiles, and foot-candle illumination requirements to ensure complete compliance with DOT, FDOT, CALTRANS, and international public works standards.
Solar street lights eliminate expensive underground electrical trenching, conduit laying, utility transformer connections, and ongoing electricity bills. They provide continuous emergency illumination during power outages and severe climate events while reducing project deployment timelines significantly.
Our complete solar street lighting systems are designed for a 20-year structural and optical service life. High-capacity LiFePO4 lithium batteries provide an operational lifespan of 7+ years before routine replacement, while monocrystalline solar panels carry performance output warranties of 25 years.
Yes. All SLI light poles and solar mounting brackets are structural-engineered to withstand extreme wind velocities up to 180 mph. Heavy-duty aluminum housings and specialized multi-layer powder-coating prevent corrosion in coastal, tropical, and high-salinity marine environments.
