Led Solar Street Light

Integrated solar street lights with everything in one housing: monocrystalline panel, LiFePO4 battery, MPPT charge controller, and LED source. For off-grid roads, pathways, parking lots, campus perimeters, parks, and remote sites where trenching a grid connection costs more than the lighting itself.

Core Specs

LED wattage: 15W / 20W / 30W / 40W / 60W / 80W / 100W / 120W / 150W. The LED wattage is the actual LED consumption, not "equivalent wattage." A 60W solar street light from us is a real 60W LED.

Solar panel: Monocrystalline PERC half-cell on models ≥ 60W. PERC gives about 1.5–2% absolute efficiency gain over standard mono. Half-cell design means the panel keeps producing even when partially shaded — on a standard full-cell panel, a bird dropping or leaf shadow can knock out an entire series string.

Panel wattage (paired with LED): 15W LED gets a 40Wp panel, 20W gets 55Wp, 30W gets 80Wp, 40W gets 120Wp, 60W gets 180Wp, 80W gets 240Wp, 100W gets 320Wp, 120W gets 360Wp, 150W gets 450Wp.

Panel efficiency: ≥ 21.5% cell efficiency. For context, standard polycrystalline is around 17–18%, standard mono around 19–20%. Every point matters when you're trying to fit enough panel onto a single housing.

Battery: LiFePO4 — this is standard on every unit, not an upgrade. NMC lithium and gel lead-acid are available on request for cost-optimized programs, but we don't recommend them and we'll tell you why before you order.

Battery capacity: 15W LED: 192 Wh / 20W: 256 Wh / 30W: 384 Wh / 40W: 512 Wh / 60W: 768 Wh / 80W: 960 Wh / 100W: 1,280 Wh / 120W: 1,536 Wh / 150W: 1,920 Wh. All values in watt-hours — multiply Ah × nominal voltage to verify. 12.8V nominal up to 100W LED, 25.6V for 120–150W.

Battery cycle life: ≥ 2,000 cycles at 80% depth of discharge at 25°C, retaining ≥ 70% capacity. That's about 5.5 years at one cycle per day before the battery capacity drops to 70%. In practice, most well-designed systems see daily DoD around 40–50% (not 80%), which dramatically extends cycle life toward the upper end of the 2,000–4,000 range.

Charge controller: MPPT — standard, not optional. ≥ 96% conversion efficiency. The controller handles dusk-to-dawn timing, dimming schedules, motion sensor logic, and battery protection (over-charge, over-discharge, over-current, short circuit, temperature monitoring).

LED efficacy: ≥ 160 lm/W at the LED source, ≥ 140 lm/W system including optical loss.

CRI: ≥ 70 standard, ≥ 80 on request. For roadway, CRI 70 is fine. Bump to 80 for pedestrian zones where facial recognition matters for security cameras.

CCT: 4000K standard, 3000K / 5000K / 5700K on request.

Light distribution: Asymmetric roadway pattern — roughly 140° wide, 70° vertical spread. This throws light along the road rather than wasting it in a circle.

IP rating: IP65 overall, IP67 on the battery compartment specifically. The battery has its own secondary seal — it's the most expensive component to replace and the most sensitive to moisture.

IK rating: IK08.

Housing: ADC12 die-cast aluminum body. Tempered glass over the solar panel — same material as a residential solar panel, just smaller.

Mounting: Side-entry for spigot ø60–76 mm. Panel tilt is adjustable 0°–45° independent of the luminaire body, so you can point the panel at the optimal solar angle regardless of where the road is. In the northern hemisphere, you want the panel facing south. In the southern hemisphere, north. Tilt angle roughly equals your latitude for year-round average optimization, or latitude minus 15° for summer-biased, plus 15° for winter-biased.

Recommended pole height: 15–20W at 4–5 m, 30–40W at 5–6 m, 60–80W at 7–8 m, 100–120W at 8–9 m, 150W at 9–10 m.

Control modes: Time-based dimming with PIR or microwave motion sensor. Default algorithm: 100% for first 3 hours after dusk, 30% from midnight to dawn, motion triggers 100% for 30 seconds then back to 30%. Programmable via IR remote or Bluetooth app.

Autonomy (design basis): Standard models designed for 3 days at 5.0 PSH. PRO models designed for 5 days at 4.0 PSH. If your location gets less than 4.5 PSH or has regular multi-day overcast periods, tell us — we upsize the panel and battery accordingly.

Communication: Bluetooth for on-site commissioning via smartphone app. NB-IoT or LoRaWAN for remote monitoring on smart city networks.

Operating temp: -20°C to +60°C. LiFePO4 handles heat better than NMC, but battery capacity still degrades faster above 45°C. If your site regularly exceeds 50°C ambient, we may recommend a split system where the battery can be buried or shaded separately.

Battery protection: Over-charge, over-discharge, over-current, short-circuit, and temperature cutoff — all managed by the BMS (Battery Management System) built into the battery pack.

Warranty: 3 years including battery standard, 5 years PRO. The battery is the wear item — if you need more than 5 years from the battery, build that into your maintenance budget or go with a split system where the battery is field-replaceable without replacing the whole fixture.

Certifications: CE, RoHS, IEC 62109 (solar PV safety), UN 38.3 (lithium battery transport safety).

Design assumptions matter

Our standard sizing assumes 5.0 PSH, 3 days autonomy, 10 hours/night operation, and max 60% daily DoD on LiFePO4. If your project site has different conditions, we re-calculate. Tell us the coordinates and the operating hours, and we'll send you the full sizing worksheet — panel watts, battery watt-hours, daily DoD at each month, and expected performance through the worst solar month of the year.

If you're not sure how many PSH your site gets, send us the coordinates and we'll pull the NASA POWER or PVGIS data for you. It's a two-minute lookup that prevents a 3-year warranty headache.
