Home Solar lighting blog News Sunna Design Unveils EverGen 3: The Future of Autonomous Solar Street Lighting 

A Pioneering Legacy in Solar Lighting 

The EverGen story began over 17 years ago in the United States, led by SOL Inc., a historical leader in high-power standalone solar solutions. In 2020, Sunna Design’s strategic acquisition of SOL enabled the merging of their respective expertise, accelerating innovation and strengthening their combined know-how. Today, EverGen 3 perfectly embodies this advanced technological alliance, offering solar lighting a new generation of advanced solar lighting systems. 

A New Generation Built for Simplicity, Durability, and Efficiency

The new EverGen 3 line sets a new standard in solar lighting with a fully redesigned system that simplifies installation through significantly reduced assembly time, while also minimizing maintenance costs and the risks of installation errors. 

Each component has been rigorously selected to incorporate the latest market technologies.   

At the heart of this innovation lies the PowerCase, an intelligent energy unit combining a high-density LiFePO4 lithium battery with the smart SunnaCore EMS controller. This unique architecture ensures precise and adaptive energy management based on local sunlight levels and usage profiles.   

EverGen 3 also integrates new cutting-edge solar panels with N-Type TOPCon cells, delivering superior efficiency of up to 26% more power at the same surface areas – even under low-irradiance environments. This technology also provides an operational lifespan exceeding 30 years. 

To complete the system, Sunna Design introduces the new Dark-Sky Approved Elektra fixture, which provides outstanding luminous efficiency (up to 210 lm/W) while complying with regulatory standards on light pollution. Remaining true to an open-ecosystem approach, the EverGen range is also compatible with qualified fixture manufacturers to meet project-specific requirements. 

Onboard Intelligence for Smart and Autonomous Lighting

Beyond its robust hardware, EverGen 3 includes an array of smart features that set it apart from traditional solar systems: 

• Built-in Connectivity: Native communication system — fully self-sufficient, with no need for additional infrastructure. 

• Synchronized Motion Detection: Lamp posts communicate with each other for coordinated lighting.  

• Hybrid Mode: Feature that allows the system to automatically switch-over when grid access is available, optimizing system sizing.  

• Extended Interoperability: Compatible with a wide range of fixtures, including decorative and ambient lighting. 

• Local Supervision: With native Bluetooth and the SunnAPP mobile application, each unit can be configured, activated, and managed on-site—no gateway needed.  

• Remote Monitoring: The optional Sunna Cloud platform enables real-time performance tracking, predictive maintenance, and asset management. 

A Strategic Addition to Sunna Design’s Global Offering

EverGen 3 complements Sunna Design’s existing product lines, such as the compact iSSL and UP solutions, by delivering a high-power response for the most demanding projects. With this expanded offering, Sunna Design now provides the most comprehensive range of autonomous solar lighting solutions on the market—designed to address a wide variety of needs in both urban and rural environments.
