Overview
As part of Liberty Wines’ ongoing commitment to sustainability, the company has invested in a comprehensive SolarEdge solar installation across the roof of their new warehouse. This generates a significant proportion of the facility’s electricity, helping to reduce both operational costs and reliance on non-renewable power sources. By adopting solar, Liberty Wines is actively reducing its carbon footprint by a whooping 89 tonnes of carbon emissions each year and reinforcing its dedication to environmentally responsible business practices.
The solar installation was completed with minimal disruption to daily operations, allowing Liberty Wines to maintain business continuity throughout the process. By embracing solar technology, Liberty Wines is setting a benchmark for innovation and environmental leadership within the wine industry, demonstrating how operational excellence can go together with environmental stewardship.

System Components
Longi Solar Panels: The installation uses premium Longi solar panels, known for their excellent efficiency and sleek aesthetics. There were 1,005 x 525W Longi Black panels being installed in total, 952 brand-new, 53 from original install, now optimised and integrated into new string plan. The existing panels receive a service and deep clean.
SolarEdge Power Optimisers: Each panel is equipped with a SolarEdge power optimiser, which enables individual panel monitoring and performance optimisation. This technology mitigates the effects of partial shading and ensures maximum energy harvest from each panel. In total we used 503 x SolarEdge S1000 optimisers.
SolarEdge Synergy Inverter: The system features SolarEdge inverters, which works with power optimisers to convert DC electricity from the panels into AC power for home use. This inverter is designed for seamless integration with the SolarEdge ecosystem, including the battery storage system. This system included 26 strings feeding into 4 x SE90K inverters.
Doncaster PV Ultra Cabling: PV-Ultra cables are engineered explicitly for DC installations in photovoltaic systems. Designed with high-quality materials for an anticipated lifespan of about 25 years and can operate at average maximum conductor temperatures of 90°C, with short-term tolerance up to 120°C. This particular project included over 4,000m of DC cabling & 430m of cable tray.
Sevadis EV Dual Pedestals: The site had 4 existing Sevadis dual 22kW charging pedestals, that had been installed but never commissioned. The team fully onboarded them to the WEVO platform and 8x charging stations were made live via the Your Insight Energy app, ready for staff and fleet use
