Solar Street Light Selector

Solar street light selection matrix

Every recommendation this selector can return, listed in full. Road width means the total carriageway width. Where a combination shows Custom configuration, it falls outside the standard range and is sized individually.

How the recommendations are made

What decides which solar street light a road needs?

Three factors dominate: how wide the carriageway is, what the road is used for, and whether grid power reaches the site. Width drives luminaire output and pole height. Road class sets the illuminance target. Power availability decides between an off-grid solar system, a grid-fed LED luminaire, or a hybrid that draws on both.

Why does the selector not ask for lux or wattage?

Because a defensible wattage cannot be derived from a short form. It depends on pole height, spacing, luminaire optics and the maintenance factor for the site. This selector narrows the field to the right product family; the exact wattage is fixed by a DIALux simulation before quotation.

Can one model cover several road classes?

Yes, and most do. The same model frequently suits an arterial road and a residential street of comparable width, because width matters more than classification. Where a model is genuinely unsuitable for a class — a decorative luminaire on a major arterial, for instance — it is excluded from that row of the matrix.

How is a solar system sized for cloudy weather?

By autonomy days: how many consecutive overcast nights the system must run without recharging. Three to five nights is typical for municipal projects. Battery capacity and panel output are then sized against local solar irradiance data for the project location, which is why the same model ships with different battery configurations in West Africa and Central Asia.

What if no model matches the site?

That combination falls outside the standard range and is handled as a custom configuration. Send the road width, pole height, nightly operating hours and required autonomy, and our engineers will size a system and return a DIALux layout and BOQ within 24 hours.

Are hybrid systems recommended differently?

Inlux Solar offers two hybrid systems — solar with AC backup, and solar with a compact wind turbine. Both are configured to project requirements rather than sold in fixed width classes, so the hybrid branch returns those two models for any site.

Does the selector cover flood lights, high mast systems and poles?

High mast systems appear under the open-area branch. Flood lights and lighting poles are supplied as project components rather than standalone road lighting, so they are quoted with the system rather than recommended here.

Recommendations reflect Inlux Solar engineering practice for typical installations. Final luminaire wattage, pole height and spacing are confirmed by a project-specific DIALux simulation before quotation. See our 14-step project roadmap for what happens between enquiry and delivery.
