Key components and rationale
LED module. Quality chips (Bridgelux, Philips, or equivalent) deliver consistent color temperature, long lumen maintenance, and tight binning for uniform fleets. Select modules with rated lumen maintenance ≥L70@50,000–100,000 hours depending on driver and thermal design.
Photovoltaic panel. Monocrystalline cells with cell conversion efficiency in the vicinity of 19–23% reduce panel area and improve performance under partial light. Tempering, anti-reflective coating, and framing are essential for long outdoor service.
Battery pack. LiFePO₄ chemistry is widely preferred for street lighting because it combines long cycle life, thermal stability, and fewer maintenance demands than lead-acid or older lithium variants. Expect thousands of cycles under conservative depth-of-discharge schedules, translating to multiple years of service.
Charge controller. MPPT controllers extract more energy from the PV array than PWM types in variable irradiance and are standard on higher-performance units. Smart controllers also manage charge/discharge, temperature compensation and low-voltage disconnects.
Housing and ingress protection. Die-cast aluminum bodies with corrosion-resistant coatings and IP65 protection protect electronics and optical assemblies from dust and water jets. Proper thermal paths extend LED and battery life.

Performance characteristics explained
Lumen output and efficacy. The lumen figure above is a product of LED wattage and system efficacy. High-quality chips and good thermal design preserve luminous flux over time. Look for LM-79 or LM-80 data or factory test results when assessing claims.
Run time and backup. Typical systems are designed for nightly operation plus multi-night backup to cover several cloudy days. Runtime can be extended with motion-activated dimming or scheduled reduction in late-night hours. In areas with weak insolation, oversizing panels or batteries prevents underperformance.
Battery life and maintenance. Compared with traditional lead-acid, LiFePO₄ offers far higher cycle counts and more tolerant thermal behavior. Proper charge strategy and avoiding deep discharges lengthen calendar life. For municipal or commercial fleets, forecasting replacement schedules based on cycle counts simplifies lifecycle budgeting.
Controls and intelligence. Modern 2-in-1 units include multi-mode controllers: fixed output, dusk-to-dawn with timed dimming, motion boost, remote control via RF or cellular gateways, and telemetry for fleet monitoring. MPPT controllers increase energy capture.
Mechanical and environmental design
IP65 rating meaning. IP65 indicates dust tight protection and resistance to water jets from any direction. This rating secures electronics against heavy rain, spray and dust ingress, but units still require correct seals and gasket maintenance for long life.
Thermal management. Aluminum housings act as heatsinks. Thermal design influences LED junction temperature and thus lumen maintenance. Pay attention to convection paths and avoid recessed installation that traps heat.
Corrosion resistance. Coastal or industrial sites need protective coatings, marine-grade fasteners, and optionally, stainless hardware.
Mounting and pole interface. Standard slip-fit or bracket options accommodate pole diameters and tilting angles for panel orientation. Modular mounting simplifies replacement without complex rewiring.
Controls, sensors and lighting profiles
Motion sensors. PIR or microwave sensors reduce average energy consumption by dimming to a low base level during inactivity and raising output when motion is detected. Proper sensor placement avoids false triggers.
Dimming schedules. Typical commercial profiles: full output for first 2–3 hours after dusk, then step down to 50% or 30% until dawn. Profiles can be customized by time or ambient light sensors.
Remote management. Fleet-level management via RF mesh, NB-IoT or LoRaWAN offers status reporting: battery state, daily energy harvest, fault codes and on/off schedules. This data supports predictive maintenance.
Safety functions. Overcharge, over-discharge, short-circuit protection and temperature cutoffs are standard. MPPT controllers include thermal compensation and adaptive charge curves to protect battery health.
Installation checklist (practical steps)
-
Confirm site solar access (shade study, azimuth, tilt).
-
Verify pole height and foundation capacity.
-
Test incoming pole for plumbness and ensure correct top adapter size.
-
Unpack and inspect for shipping damage; check seals, lens, and connectors.
-
Set tilt angle for solar panel (fixed or adjustable bracket).
-
Commission controller and set local time, dimming schedule and sensor sensitivity.
-
Validate battery state of charge and perform first-night test run.
-
Record serial numbers and install remote monitoring if supplied.
A trained electrician or technician should complete final commissioning. Quick installation and minimal cabling are advantages of integrated 2-in-1 units.
Operations, preventive maintenance and lifetime planning
Routine checks (annual). Clean PV surface, inspect seals, tighten fasteners, verify firmware and controller logs, and replace consumables per manufacturer guidance.
Cleaning schedule. Panels typically require cleaning 1–3 times per year depending on dust and pollen loads. Clean with water and soft cloth; avoid abrasive materials.
Battery replacement planning. Use cycle life figures and average depth-of-discharge to predict replacement intervals. LiFePO₄ may last many years; keep battery serials and operating logs to support warranty claims.
Decommissioning. Separate recyclable components: aluminum, glass, and recyclable battery cells following local hazardous waste rules.
Procurement and testing considerations
Factory acceptance tests. Request the following: electrical performance (I–V curves for PV), full system runtime test under simulated load, IP ingress verification, thermal cycling of battery pack, and LED lumen output measurement.
Certificates and standards. Seek CE, RoHS, UL or IEC standards relevant to your market. Photometric reports and LM-79/LM-80 test data increase confidence in lumen claims.
Warranty and spares. Clarify the warranty window for LED module, battery and electronics. Keep spare controllers and batteries for large installations to minimize downtime.
Vendor transparency. Ask for bill of materials, detailed drawings and site reference installations. A supplier that provides test data, production traceability and monitoring solutions reduces project risk.
Logistics, packaging and handling
Packaging. Units should ship in crush-resistant boxes with foam holds and external markings for handling orientation. Batteries may be shipped under special lithium battery regulations — confirm carrier arrangements.
Shipping modes. Sea freight for bulk orders and air for urgent deliveries. For cross-border shipments, supply documentation for customs clearance and battery transport papers.
On-site staging. Store dry and shaded until installation. Rotate stock and tag serials for warranty traceability.
Troubleshooting and common faults
Failure to power on at dusk. Check PV orientation, clean panel, verify controller settings and battery voltage. Ensure no installation error like reversed connector.
Reduced runtime. Typical causes: prolonged shading, battery degradation, incorrect dimming profile, or defective cells. Review controller logs and calculate energy balance.
Flicker or intermittent output. Check thermal contacts, driver connectors, and loose wiring. Verify firmware and controller health.
Ingress or corrosion signs. Replace gaskets, reseal envelopes and inspect for evidence of water entry. If internal components show corrosion, consult warranty and replace affected parts.
Why LiFePO₄ is commonly chosen for these units
LiFePO₄ batteries provide a favorable balance: long cycle life, robust thermal stability and lower maintenance. For fleet operators, the lower frequency of replacements and simpler management routines reduce lifetime cost. Planned battery sizing and conservative depth-of-discharge policies produce predictable replacement schedules suitable for municipal budgeting.
Cases and selection advice
Urban street lighting. Use 40W–80W depending on spacing and required lux. Choose beam pattern Type II for long narrow roadway illumination and Type III/IV for wider streets.
Parking lots. Favor higher lumen options and wider beams. Consider motion profiles tied to vehicle detection.
Campus and pathways. Lower wattages with higher pole density produce uniform appearance while saving energy. Prioritize aesthetic housing with anti-glare optics.
Rural and remote corridors. Oversize battery to provide multiple backup nights and maybe a larger panel to compensate for seasonal low insolation.

Frequently asked questions (FAQs)
1. What does “2-in-1” mean for this solar street light?
“2-in-1” generally describes an integrated form factor combining both the lighting module and the solar power subsystem (panel plus battery) into one or two connected assemblies. This design reduces cabling, simplifies installation and shortens deployment time.
2. Is IP65 sufficient for outdoor use in heavy rain?
IP65 provides dust-tight protection and resistance to water jets. It handles rain and spray well. For immersion or very high-pressure washing, a higher rating is required, but IP65 is standard for most street-lighting applications.
3. How many nights of backup will the unit supply?
Backup capacity depends on battery size and energy consumption. Typical factory profiles aim for 2–7 nights of backup for the 30W–80W range under conservative dimming strategies. Exact performance varies by location and usage profile.
4. Which battery chemistry should I choose?
LiFePO₄ is the recommended common choice due to long cycle life, stable thermal behavior and predictable aging. It generally outperforms lead-acid and older lithium chemistries for outdoor street lighting.
5. How to size panel and battery for a site?
Perform an energy audit: estimate average nightly consumption (W × hours), include system losses, then size battery for desired autonomy and PV for average daily generation plus charge margin. If doubt remains, oversize the PV array rather than under-size the battery.
6. Can the lights be remotely monitored?
Many modern units include options for remote telemetry (LoRaWAN, NB-IoT, cellular). Fleet monitoring allows real-time status, fault alerts and scheduling changes.
7. What maintenance is required?
Routine PV cleaning, inspection of seals, firmware updates and battery state checks. Annual inspections are standard; frequency may increase in dusty areas.
8. What certifications should I request from suppliers?
Ask for LM-79/LM-80 photometric reports, IP ingress test records, CE/IEC or UL documents relevant to your market, and independent battery test data. Factory test records and a clear warranty policy are critical.
