Anti-blackout feature: the iSSL® features proprietary adaptive lighting algorithms that adjust the light flow automatically to ensure proper lighting throughout the night, all year long.
Theft-proof: Components are placed within the housing, at the top of the pole, to prevent theft. The mounting bracket cannot be removed from the pole without appropriate equipment (theft-prevention kits are available on request).
Reduced installation time: Thanks to its plug & play design, it only takes 20 minutes to install a light, pole included. There are no special skills needed. Reduced time to install = reduced project cost.
Built to resist even the most severe weather: Because of its unique battery technology and patented passive cooling system, the iSSL® series will operate consistently whether in the middle of the desert or surrounded by ice and snow.
The only integrated solar light that can be air-shipped: The iSSL® has been designed to be deployed quickly, anywhere around the world. It doesn’t use materials classified as dangerous goods by the FAA and can therefore be shipped by air.
Incredible reliability: 100% of our systems are tested before they leave the factory. Our latest calculations show a 0.5% failure rate, based on the 25,000 units deployed since 2015. In the rare case of product failure a complete replacement is provided to minimize downtime and impact on users.

4 Reasons to choose the iSSL® solar street light series

1. Smart Lighting Management = A solar light that doesn’t run out of juice.

With patented built in intelligence, our lights gather weather data from the previous few days while constantly monitoring the amount of energy available in the battery system. It automatically combines this information to regulate light flow and avoid any interruption in lighting service. A truly SMART street light – always on and always thinking.

2. Light(n)ing fast installation:

Deploying lighting infrastructure has never been faster or easier, thanks to the all-in-one, plug and play design of the iSSL® series. No cabling or trenching required. Every component is located inside the housing. Simply unbox the iSSL®, attach its mounting system to the pole and switch it on! The current iSSL® installation speed record is 20 minutes per light, pole included.

3. Remote Monitoring & smart city features:

Through our ‘always on’ supervision platform, we can monitor the status of your streetlights from any device, anywhere as long as it is connected to the Internet. By adding sensors that monitor things like air quality, power devices like CCTV cameras, or creates a public WiFi network, we are building the smart communties of tomorrow – today.

4. Extreme Weather Resistance:

Our lights are engineered to withstand up to Category 5 hurricanes and to work effectively at temperatures between -40 °F and +158 °F, making them the ideal streetlighting solution almost anywhere in the world.

Build & Price your iSSL® Solar Light

Thanks to our Build & Price tool, you will get a preliminary count and budgetary quote for your iSL® solar light. All we need is your application, project location and project dimensions.

Choose an application below, then input your project information so our powerful sizing engine can build and test an iSSL® solar light that meets your needs. The sizing engine takes your project location and runs it through thousands of environmental simulations to ensure each system performs as expected. Accurate sizing is the key to a cost-effective light that will perform exactly as you expect throughout its lifespan—and won’t prematurely kill your batteries.

Once you receive your customized quote, you can then compare your solar lighting project cost to traditional grid-connected lighting. After reviewing the comparison, the next step is to contact us for a free detailed system overview and lighting layout, breaking down all the specifications for your project.
