What “2-in-1” means in modern solar street lighting

The term 2-in-1 refers to a two-piece architecture commonly used in contemporary solar roadway lighting. In this arrangement the PV module sits separate from the luminaire. The lamp contains LED array, battery, and control electronics. The split layout keeps the panel free to be sized and oriented independently, while the lamp body remains compact.

This pattern combines the visual advantages of integrated fixtures with the flexibility of split systems. Projects needing larger PV capacity gain that ability without an oversized lamp housing. Several manufacturers adopt this format to balance performance and simplified installation.

Core components and engineering notes

LED module

High-power SMD LEDs or COB arrays are mounted to a robust aluminium heat sink. LED bins selected for high luminous efficacy reduce required wattage to achieve given lux levels. Optics are available in various distributions to fit street, highway, or parking area use.

Power electronics

MPPT charge controllers provide efficient PV energy harvesting and prevent battery overcharge. Constant-current LED drivers with dimming capability maintain lumen output and protect diodes from thermal runaway. Surge protection and transient suppression are recommended for exposed installations.

Battery chemistry

LiFePO₄ batteries deliver a stable cycle life and thermal safety. Typical system design chooses battery capacity to guarantee 2–5 nights of autonomy under regional cloud probability. Battery pack modules often include BMS for cell balancing and temperature protection.

Solar panel

Separate panels permit larger area for energy capture. Monocrystalline panels yield higher efficiency per area, useful where pole top space is limited.

Sensors and remote

Integrated motion sensors and remotes enable adaptive operation: high output during activity, low standby during idle periods. Remote control allows configuration of time schedules, dimming curves, sensor sensitivity, and emergency override.

Product literature from leading suppliers confirms these component approaches and recommended practices for 2-piece solar street systems.

Photometry, energy budget, and expected runtime

Photometric expectations

Modern LEDs at 140–170 lm/W produce broad lumen packages. Estimated lumen outputs for the family:

• 100W: ~14,000 lm

• 200W: ~28,000 lm

• 300W: ~42,000 lm

• 400W: ~56,000 lm

• 500W: ~70,000–85,000 lm (depends on bin and optics)

Choose optics that match road classification: narrow lateral distribution for narrow roads; wider patterns for plazas or parking.

Energy harvesting and battery sizing

Energy harvested depends on panel wattage, sun hours, orientation, and local weather. System designers commonly size PV and battery to provide 2–5 nights of autonomy. MPPT controllers raise effective harvest by tracking panel power. For example, a 300W lamp might pair with a 300–600W PV panel array and a battery bank sized for 1,800–3,600 Wh usable energy, depending on autonomy targets.

Example runtime calculation (simplified)

• 300W LED at 150 lm/W uses 300W electrical. Nighttime schedule: 10 hours at average 60% output due to dimming/motion. Effective nightly consumption ≈ 300W × 10h × 0.60 = 1,800 Wh.

• Battery usable capacity chosen at 2,400 Wh to provide margin. With MPPT and average insolation yielding 1,800–2,500 Wh daily, the system meets daily loads and stores reserve for cloudy days.

These calculations are consistent with standard solar street practices. Designers should perform location-specific irradiance checks prior to final sizing.

Mechanical design, ingress protection, and thermal management

IP65 rating protects against jets of water and complete dust ingress. This rating does not imply submersion resistance. For coastal or industrial sites with corrosive atmospheres, higher corrosion resistance coatings and stainless fasteners are recommended.

Thermal paths in the lamp body are critical. Aluminium housings with deep fins conduct heat away from LED boards and battery enclosures. Forced ventilation is usually avoided because it permits dust ingress. Instead, conduction and radiant cooling are engineered to keep junction temperature within LED and battery recommended bounds.

Robust gasketing ensures the controller and battery compartments remain dry. Cable entries should have IP-rated glands and strain relief to preserve long term sealing.

Manufacturer technical files for robust solar street family designs emphasize these mechanical strategies.

Control system, remote programming, and operational modes

Remote control is a major value point for SunplusPro systems. Typical remote functions:

• Full on / full off toggle

• Multi-step dimming (example: 100% → 60% → 30%)

• Motion-triggered boost (returning to low power when idle)

• Time schedules (night duration, seasonal settings)

• Sensor calibration (light threshold, motion sensitivity)

• Factory reset and firmware update triggers if supported

Advanced remote programmers allow group addressing so multiple lights can be set with single device during commissioning. Wireless remote steps reduce ladder time and provide flexible scene setting for projects.

LED remote programming hardware used in commercial solar street deployments is designed for field reliability. For larger projects, integrate remote programmer workflows into commissioning checklists to achieve consistent citywide behavior.

Choosing the correct wattage and optics

Selection depends on road classification, mounting height, and required uniformity.

Quick guide

• 100W: small lanes, pedestrian paths, bike tracks; mounting height 3–5 m.

• 200W: residential streets, service roads; mounting height 4–6 m.

• 300W: collector roads, small urban arterials; mounting height 6–8 m.

• 400W: major urban arterials, larger intersections; mounting height 8–10 m.

• 500W: high-speed roads, expressways, large plazas; mounting height 10–14 m.

Consider lumen output and desired lux levels, not wattage alone. Optics matter: Type II and III suit linear roads; Type V suits open areas.

Adjust PV sizing upward in high latitude or heavily shaded locations and in regions with frequent inclement weather.

Installation, commissioning, and maintenance

Installation highlights

• Mount PV panels with tilt and azimuth adjustments for optimal irradiation.

• Pole brackets should accept both top-mount and side-arm orientations.

• Use MC4 connectors for PV cabling where possible for standardization.

• Verify torque on fasteners to maintain sealing integrity.

Commissioning checklist

• Confirm battery voltage and BMS status.

• Set remote configuration and test motion/ambient sensors.

• Perform photometric verification at night: measure lux at test points to confirm uniformity.

• Verify data logging if telemetry present.

Maintenance

• Visual inspection 1–2 times per year.

• Clean PV surface periodically to maintain harvest (frequency depends on soiling rate).

• Replace battery modules when capacity drops below project threshold (common replacement between 4–10 years depending on chemistry and cycle depth).

Several supplier datasheets emphasize ease of maintenance for 2-piece systems because battery access is localized to the luminaire, while panel replacement remains straightforward.

Compliance, certifications, and durability testing

Commercial lighting units should be verified for:

• Photometric performance (IES files or LM-79 reports)

• Electrical safety and EMC standards based on region (CE, RoHS, etc.)

• Battery safety certifications relevant to chemistry chosen

• Ingress rating confirmation (IP65 testing)

• Surge protection and lightning mitigation recommendations

Demand factory test certificates for larger procurements. Warranty and service level agreements must define battery replacement responsibility and shipping times for spares.

Supplier pages for integrated solar luminaires commonly list CE, RoHS, and other export certifications; request test evidence during procurement.

Packaging, shipping, and logistics considerations

Large-watt fixtures and separate PV panels need careful packaging. Palletized shipments with internal blocking reduce transit damage. For overseas projects, check customs duties for battery shipments because battery chemistry can add hazardous goods restrictions; LiFePO₄ typically carries fewer restrictions than other lithium types but still requires correct labeling and paperwork.

For rapid urban deployments, consider local warehousing of spares (drivers, sensors, battery modules). This reduces downtime from waiting on cross-border logistics.

Frequently asked questions

Q1: What does 2-in-1 mean, and why pick it over all-in-one?

A: 2-in-1 refers to separate solar panel and combined lamp body. The split layout permits larger panel sizing and optimized tilt without enlarging the lamp housing. The design often simplifies thermal design in the lamp and reduces heat exposure to PV cells. Systems using this pattern are common in municipal projects that demand higher energy harvest and easier panel maintenance.

Q2: What does IP65 protect against, and is it enough?

A: IP65 prevents dust ingress and protects against jets of water from any direction. It does not cover temporary immersion. For coastal zones, add corrosion protection. For locations subject to floods or prolonged spray, choose higher ingress protection or added enclosures.

Q3: How long will these lights run through cloudy weather?

A: Runtime depends on battery sizing, panel size, and local insolation. Typical designs plan for 2–5 nights of autonomy. For guaranteed multi-day operation, scale panel and battery capacity upward. MPPT controllers help maximize harvest in marginal conditions.

Q4: How does remote control improve operation?

A: Remote configuration speeds commissioning and permits field tuning without disassembly. Operators can set dimming schedules and motion boost levels quickly. Group addressing simplifies setting multiple lights on a single pole run.

Q5: Which battery chemistry is best?

A: LiFePO₄ balances cycle life, thermal stability, and safety. It often provides longer life compared to lead acid while being safer in thermal abuse. Confirm local transport rules when shipping cells.

Q6: What maintenance is required?

A: Annual visual checks, PV cleaning frequency based on soiling rates, and periodic battery capacity checks. LED modules have long life; battery replacement typically drives mid-life service events.

Q7: Which wattage should I order for a 7 m pole on a city collector street?

A: A 300W or 400W unit typically fits collector roads at 6–8 m heights. Choose optics that spread light along the carriageway for uniformity. Conduct a simple point-by-point photometric check during commissioning.

Q8: Can multiple luminaires be synchronized or managed centrally?

A: Many systems support remote programmers that configure groups. For full telemetry, integrate a dedicated street lighting management system (SLMS) with wireless nodes or LoRa/Wi-Fi gateways for scheduled control, fault reporting, and energy analytics.
