Solar Street Light Fixtures
For municipalities, highways, bridge and rural development projects, Solar Lighting International street lamp systems are reliable and effective.
All of our lighting systems are designed in the US from our Lancaster SC location.
We have the flexibility to work with you in creating a system that is suited to your situation and budget.
SLI’s X-35-LED street lights use Cree LED chips as well as Phillips Illumiled LED Chips.
Our lamps come in many options: 4400 lumens, 9750 lumens, and 14300 lumens for standard fixtures. SLI can even double the pole for up to 28,600 lumens for environments where a wide light coverage is needed.
That means more light where you need it and more cost effective solutions where fewer lumens will do the trick.
We specialize in complete system design and installation. We have a proven track record in delivering systems around the world and across multiple language and cultural barriers.
In addition to reducing energy usage, these systems require less need for backup power during natural disasters, require less line maintenance and reduce grid load. Light Emitting Diodes also help reduce light pollution.

The popularity of commercial solar-powered street lamps have grown a considerable amount, especially in the last decade. They are now considered the go-to green alternative to powergrid lighting.
They provide a cost-effective, sustainable, lower maintenance, renewable energy source that is the optimal replacement for almost all applications.
Since they are not tied to the grid they add a level of hardening to any community as they can dependably run under most conditions including natural disasters without requiring backup power.
These lamps run at any time needed with certain operating configurations. They can be set to turn on at dusk and off at dawn or during split times. Light pollution can be reduced by utilizing these cutoff times. The state-of-the-art light emitting diode technology also helps
Mounted at the top of the light pole is the photovoltaic panel, oriented so that it faces south in direct sunlight with no shade. The system is connected to a Maximum Power Point charge controller (MPPT), then to a battery assembly that can be located either behind or directly underneath the panel.
(It can also be attached lower down the pole in a lock box for easy maintenance access.)
The mounted photovoltaic panel uses sunlight to charge the battery throughout the day which will provide energy during the night.
Our engineers will design your system while taking into consideration several factors including, but not limited to, the location of the light, local wind load requirements, the weather conditions in winter, and the operation profile.
Custom Outdoor Lamps
Various types of lamps can be operated by the fixture, relying upon on the need.
The common most kinds of lamps used with solar panels are light emitting diodes (LED) or compact fluorescent lamps (CFL). There are other options for projects that have different requirements. It’s important to discuss the options available with one of our specialists for optimal savings.
Since advanced LED technology is available, we are seeing more communities choose this option. These bulbs require less power, ad less expensive to install and maintain, and produce less light pollution.
Urban, Road, Commercial, Disaster….
After the sun goes down, the photovoltaic panel communicates with the electronic controls, acting as a photocell, powering the light fixture on. It is kept on from dusk till dawn or for a certain number of set hours by the control electronics.
The charge controls will reverse the process in the morning and start to charge the battery again. During the daylight hours, the battery will charge at various levels all dependent on the sun’s strength and the weather. It’s very important to guarantee that the panel is free of shade because this can cause it to not charge correctly for proper operation the next night.
We offer an all-inclusive solution to almost any application without the need to trench in grid power. Even if there is a blackout, commercial street lights will continue to operate since they are completely independent. these also work well for new subdivision communities, construction sites, and disaster areas.
