What wattage solar street light should I buy?

Wattage is not the only answer

Start with the road.
A 60W solar street light might outperform a 100W model when the optical design, battery capacity, and installation height are correctly matched, because lighting performance depends on the entire system rather than a single number printed on the label.

Too simple.
I have checked projects where buyers selected wattage first and discovered later that the solar panel, LiFePO4 battery, and LED efficiency were completely mismatched, which meant higher cost without better illumination. Why buy extra power that never reaches the ground?

Real projects need real calculations

A rural highway project in Kenya used 80W LED Solar Street Lights with 150W solar panels and 60Ah LiFePO4 batteries. The poles were installed at 8 meters, with a spacing of around 30 meters, and the lighting result was more stable than a previous 120W installation using weaker components.

That surprised many people.

The reason was simple: the 80W system used better optical lenses, a Philips LED module, and an intelligent MPPT controller, while the higher wattage system suffered from poor energy management. More watts do not automatically mean more brightness.

Matching wattage with application

Residential streets often work well with 20W–60W Solar Street Lights, while highways, industrial areas, and large public roads may require 80W–150W or higher. Factors such as road width, mounting height, required lux level, and local sunlight hours should guide the selection.

From my ten years in this industry, I prefer checking the lighting simulation before checking the wattage. It saves headaches later. Companies like likelite.com usually focus on complete system matching rather than selling only high-power models.

Technology changes the wattage equation

Modern LEDs such as 3030 and 5050 packages can deliver strong output with lower energy consumption. A well-designed 60W system today may replace older 100W Products from several years ago.

Small mistakes happen.
I once saw a specification sheet describing “luminocity” instead of luminosity, but the real problem was not the spelling — it was that nobody checked the actual photometric data.

Hoping to work with us in future.
