Solar PV for New Self-Storage & Warehouse Units

Jelmac Properties, a property developer with a diverse portfolio of offices, warehouses, and industrial units, recently expanded into the self-storage market with purpose-built facilities at their Grantham site.

With sustainability a core part of their strategy, Jelmac are committed to reducing carbon emissions across both new and existing properties. As part of this approach, Step Energy were appointed to design and install solar PV systems to support clean energy generation at the new self-storage and warehouse units.
