SOLTECH I is a high-efficiency integrated solar street-light system engineered for dependable off-grid or hybrid operation. It combines advanced monocrystalline solar panels (up to 23 % efficiency) with long-life LiFePO₄ batteries rated for 4,000 + cycles and 5 – 10 years of use. The system delivers powerful, energy-efficient illumination—up to 210 lm/W—through premium 5050 LED chips and a precision-engineered optical lens for wide, uniform coverage.
The integrated design houses the solar module, LED fixture, battery, controller, and motion sensor in a single weather-sealed (IP67/IP66) assembly, ensuring fast installation and minimal maintenance. Intelligent MPPT and hybrid controllers optimize solar tracking and charge efficiency, while adaptive lighting modes automatically adjust brightness based on motion and ambient light conditions to extend battery life through the night.
With models ranging from 20 W to 90 W and outputs up to 18,900 lumens, SOLTECH I suits diverse roadway, parking-lot, and pathway applications. The system supports remote control, NEMA 7-pin connectivity, and a variety of Type II/III/M light-distribution options. Certified for CE and ROHS compliance, it offers a reliable, sustainable lighting solution built to perform in environments from –35 °C to +65 °C.
