During daylight, the solar panel mounted on (or near) the light pole converts sunlight into electricity. 
Specifications
- <p class="ql-align-center"> <strong>Specification / Feature</strong></p><p class="ql-align-center"> <strong>Typical Range / Value / Description</strong></p><p> LED Power / Wattage</p><p> From about 10 W (small walkway lights) up to ~150 W or more (for larger street / road lights) depending on coverage needs. </p><p> Light Output (Lumens)</p><p> Roughly 1,000 – 15,000 lm depending on wattage / size of the light — enough for street illumination or pathway lighting. </p><p> Solar Panel</p><p> Monocrystalline or polycrystalline solar PV panel; size depends on wattage — e.g. 50 W, 80 W, 100 W or more for larger lights. </p><p> Battery</p><p> Rechargeable battery (often lithium‑ion, LiFePO₄, or sealed/gel lead‑acid depending on design); capacity varies widely (e.g. 20 Ah to 100 Ah + depending on light wattage and autonomy requirements). </p><p> Autonomy / Backup Runtime</p><p> A good solar street light can often keep lighting through the night, and many designs aim for ~10–12 hours of night lighting on full charge; some “smart” models dim or reduce output to extend to several nights (2–5 days) if no sunlight. </p><p> Color Temperature / Light Quality</p><p> Many deliver a neutral to cool white light (often around 5000 K–6500 K), sometimes adjustable depending on design. </p><p> Controller / Smart Features</p><p> Built‑in controller (often PWM or MPPT), dusk‑to‑dawn auto turning, overcharge/discharge protection, and sometimes motion sensor / dimming / light‑sensor + timer for efficiency. </p><p> Durability & Weather Resistance</p><p> Weather‑proof / water‑resistant housing, typically rated IP65–IP66 (dust and water protection) for outdoor use. </p><p> Installation Height / Coverage</p><p> Often mounted on poles (e.g. 4–8 m or higher) depending on the area — street, pathway, parking lot, compound, etc. </p><p> </p>
