Performance, Runtime, and Autonomy
5) How many hours can the light run each night?
Runtime depends on battery energy (Wh), dimming profile, and weather. PMW configures operation based on project needs (e.g., higher brightness during peak hours and reduced brightness after midnight).
6) What does “autonomy” mean in solar street lighting?
Autonomy refers to how many nights the light can operate without new charging, such as during rainy or cloudy days. Typical autonomy targets are 1–3 nights, depending on project requirements.
7) Can PMW solar street lights work during rainy season or monsoon?
Yes—when properly designed. PMW sizes systems using local sun conditions, loss factors, and appropriate battery autonomy to reduce downtime risk.
8) How do you size the solar panel correctly?
Solar panel sizing is based on daily load (Wh), local sun hours, and system losses (temperature, wiring, controller, battery efficiency, dirt/soiling, shading). PMW uses an energy-balance approach rather than brochure wattage.
9) How do you size the battery correctly?
Battery sizing depends on required runtime, autonomy nights, dimming profile, and depth-of-discharge strategy. PMW recommends specifying capacity in Wh for fair comparisons.
Battery, BMS, and Reliability
10) What battery chemistry does PMW use?
PMW solar street lights use Lithium Iron Phosphate (LiFePO₄) batteries due to strong safety characteristics and suitability for daily outdoor cycling.
11) Why is battery watt-hour (Wh) more important than Ah?
Wh is the true energy capacity: Wh = Voltage × Ah. Two batteries with the same Ah can have very different energy if voltage differs. PMW recommends using Wh in specifications.
12) What is the difference between 3.2V and 25.6V battery architecture?
A 3.2V system (single-cell) often needs higher current to power street lighting, which can increase heat and accelerate degradation. A 12.8V (4S) or 25.6V (8S) LiFePO₄ pack reduces operating current and is commonly used for infrastructure-grade performance.
13) What is a BMS and why does it matter?
A BMS (Battery Management System) protects the battery by managing over/under-voltage, over-current, short-circuit protection, temperature monitoring, and (for series packs) cell balancing—all critical for long service life.
Lighting Design, Lux, and Documents
14) How do I know the lux level or candela will meet project requirements?
Lux performance depends on mounting height, spacing, road width, and optic distribution. PMW can provide IES files and lux/uniformity calculations for consultant review. Our engineering team could help from DIALUX Simulation, product design, prototype to post-delivery that we conduct lux and candela test on site.
15) Does PMW provide IES files and lighting simulation support?
Yes. PMW can provide photometric (IES) files and lighting simulation support to match project requirements.
16) What pole height and spacing are recommended?
Typical pole heights include 4m, 6m, 7m, 8m, 9m, 10m and 12m, depending on road type. Spacing depends on the optic and required uniformity. PMW can recommend pole height and spacing based on lux targets.

Solar LED Street Light + Concrete Pole FAQ (high-value differentiator)
24) Why is a concrete pole a strong match for solar LED street lights?
Concrete poles are an excellent match because solar street lights are long-life infrastructure assets, and concrete poles provide high durability, long service life, and strong safety performance, especially in public projects.
25) What are the key benefits of concrete poles versus steel poles for solar street lights?
Concrete poles can offer advantages such as:
- High structural durability and long lifespan
- Strong resistance to corrosion (especially in coastal or high-humidity areas)
- Stable performance for high-wind conditions
- Reduced risk of severe corrosion-related failures over time
(Selection depends on site environment and engineering design.)
26) How does a concrete pole improve safety for public infrastructure?
Concrete poles are designed for strength and stability, supporting safer installations for road users and helping infrastructure owners reduce structural risk over the project lifecycle.
27) Does concrete pole durability reduce total cost of ownership (TCO)?
Yes. A durable pole reduces the frequency of replacements and major repairs, helping lower long-term maintenance costs—especially when paired with properly sized solar lighting systems.
28) Is concrete pole suitable for coastal areas like islands and seaside towns?
Concrete poles are often preferred in coastal environments because corrosion risk is generally a major concern for metallic structures. Final selection should follow project engineering requirements and local standards.
