Following a site visit and discussions with both the developer and main contractor, several critical problems were identified. The mix of existing solar lights featured a fixed panel and light engine design, which meant the panels could not be angled to maximise sunlight capture without misaligning the light beam from the intended pathways. A split-panel arrangement, with two opposing panels, further reduced efficiency — one panel was almost always facing away from optimal sunlight, dragging down the overall output. Shading from nearby trees and buildings compounded these challenges, as even small amounts of shade on a single solar cell can significantly reduce the panel’s performance.

 

Beyond hardware limitations, the system lacked intelligent power and lighting management. There was no dimming schedule, PIR motion detection, or remote management, resulting in inefficient use of stored energy. Worse still, the system’s core components were mismatched — the battery capacity, solar generation potential, and energy demands were not aligned. This made the system particularly vulnerable during winter, when sunlight is limited.

 

To address these challenges, Vision Illumination proposed the NANO Solar luminaire — a UK-designed solution purpose-built to overcome such issues. Its flexible design allows the solar panel and light engine to be adjusted independently, enabling optimal panel orientation for maximum charging while directing light precisely where it’s needed, reducing light spill into neighbouring properties and habitats.

 

At the heart of the NANO Solar is the Titanvolt battery — offering full depth of discharge, operation in temperatures as low as -25°C, and charging speeds up to six times faster than conventional LFP or Lead Acid batteries. This technology ensures consistent performance even in the harshest UK winters. Additional benefits such as a 10-year warranty and optional remote monitoring provided further assurance to the project stakeholders.

 

Working closely with the contractor, Vision Illumination provided installation guidance and technical support to ensure correct deployment. The contractor praised the ease of installation and the system’s ability to deliver the required lighting levels without a mains connection.

 

The Crescent Gardens project stands as a testament to the value of early collaboration between developers, residents, contractors, and manufacturers. By combining stakeholder engagement with a purpose-designed product, Vision Illumination was able to replace an underperforming system with a safe, sustainable, and efficient lighting solution — ensuring year-round illumination for residents while meeting the site’s environmental goals.
