How many hours should a solar street light operate each night?
Most municipal and commercial projects are designed for 10–12 hours of nightly operation.
The final lighting schedule depends on:
• Local regulations
• Battery capacity
• Solar irradiation
• Backup-day requirements.
How many rainy days should the battery be designed for?
There is no universal answer. The required battery backup depends on the project’s location, local climate and reliability requirements.
For most municipal and commercial solar street lighting projects, we typically recommend designing for 2–3 backup days. In regions with extended rainy seasons or critical infrastructure, 4–5 backup days may be more appropriate.
Our engineering team evaluates local solar irradiation, lighting schedule and battery capacity to recommend the most suitable system configuration.
What pole height is suitable for an 8–10m wide road?
For roads with a width of 8–10 meters, an 8m pole is typically recommended for two-lane roads, while a 10m pole is more suitable for wider roads, intersections or projects requiring higher lighting uniformity.
The final pole height should be determined based on road width, pole spacing, mounting arrangement, required illuminance and local lighting standards.
Lighting simulations such as DIALux can also be provided to verify pole height, spacing and illuminance before project implementation.
Our engineering team can recommend the most suitable pole height and lighting layout according to your project requirements.
How do I compare battery capacity between different suppliers?
Battery capacity should not be compared by the Ah rating alone. A complete evaluation should consider battery voltage, total stored energy (Wh), battery chemistry, cell quality and the actual system configuration.
For example, two batteries with the same Ah rating may provide very different energy storage if their voltages are different.
When comparing quotations, always ask for the battery voltage, energy capacity (Wh), LiFePO₄ cell grade, expected cycle life and warranty, rather than relying only on the advertised Ah value.
Our engineering team can help review supplier specifications and ensure different proposals are compared on an equivalent basis.
What information is required before preparing a quotation?
To prepare an accurate quotation and system recommendation, we typically require basic project information such as the installation location, application scenario, road width or site dimensions, lighting requirements and the expected operating hours.
If available, drawings, project specifications or tender documents can help us recommend a more suitable configuration and avoid unnecessary costs.
Even if your project is still in the planning stage, our engineering team can provide preliminary recommendations based on the available information.
How can I evaluate a solar street light sample?
A quality sample should be evaluated as a complete lighting system rather than by appearance alone.
We recommend checking the LED performance, battery capacity, solar panel output, controller settings, material quality, waterproof protection and overall workmanship.
For engineering projects, it is also important to verify lighting performance through on-site testing or lighting simulations, ensuring the sample meets the project requirements before mass procurement.
Our engineering team can provide technical documentation and testing recommendations to support your evaluation process.
