California offers the perfect environment for maximizing returns on a solar street light installation.

Solar Lighting International offers a superior quality solar lighting system.

Most of the solar lighting companies resell products that are manufactured in China. These fly-by-night businesses have either figured out that by playing roulette with quality, they can significantly pad their margins through volume.

What sets Solar Lighting International apart is that our American-designed lighting systems are superior in quality. Additionally, by operating with lower overhead, we are able to provide a better quality product that does not cost significantly more. Over the life of our light, you enjoy lower maintenance and repair costs, allowing you to realize a faster payoff with a much smaller maintenance team.

We offer many different options. You can choose from different pole heights and designs, and from a wide array of LED luminaire heads. When you submit your request for proposal, our engineers will customize some options for your team to choose from to help you reach the best option (Simply fill out the contact form for this free service).

We also provide retrofit systems. These lights can be installed on your existing light poles, further reducing costs when converting an existing system to solar power.

Our lights do not need to be connected to a local grid.

Installing Solar street lights for your business, municipality or community is one of the ways you can dramatically cut costs while building all-weather resilience. 

We offer different levels of lighting, depending on your needs. As always, quality is of the utmost importance. Here’s what makes our lights better:

A Better Light

Unlike many of the brands that merely resell other companies’ solar lights, we decided to take a different road.  

Our Research and Design Center has optimized the LED configurations and lighting spread to deliver the best lighting with the least amount of power. Using the latest Phillips 160-170 lumen per watt LED chips.

But, we didn’t stop there.

Our lights offer Easy Assembly and Disassembly, Strong heating ventilation to avoid lacerate and dust deposition, and 5 years of warranty for the whole luminaire.

Whether you need 10 light poles or 1,000, we can deliver your next project.

No auxiliary power and no trenching required. Our lights are designed to work 100% off-grid reliably for many years.

Solar Lighting International’s street lamp systems for parking lots and highways come in many options: 6400 lumens, 13000 lumens, and our new 16,000+ lumens for standard fixtures.

A Better Panel

One of the largest costs in the lifetime of a panel is wind damage. We chose a monocrystalline panel that is strongly resistant to high winds and paired that with a pole and mounting structure that is robust enough to handle the remotest regions of planet earth.

Our solar panels deliver up to 50% more power per unit area and have a reduced voltage-temperature coefficient. They also excel in high temperature and low-light conditions, which means they begin producing power sooner and continue producing power longer, guaranteeing a reliable source of energy for your street light.

A Patented Solar Charge Controller

Our charge controller uses patented MPPT  ( Maximum Power Point Tracking) charging technology. This allows our controller to increase charge current by up to 30% more over conventional solar charge controllers. More power for less cost!

This added current capacity enables us to manage better, store, and conserve energy which means you get the most out of each solar panel.

We also can network these solar charge controllers together. This gives up to 8 controllers the capacity to communicate with one another and act as a single controller. This works great for Smart City Technology.

Solar Parking Lot Lights and Solar Street Lighting Designed For California


Whether you are a corporation, government agency, or small business, our solar outdoor lamp options are designed with a low total lifetime cost in mind.

We are honored to be playing a role in creating the next generation of California infrastructure.

No trenching is required.  Simply install and deliver light to where you need it, whether or not existing infrastructure is in place.
