109kW Commercial Solar Installation in Leatherhead

Commercial challenge

A commercial business in Leatherhead wanted to reduce its reliance on grid electricity, manage rising energy costs and support its carbon-reduction targets.

The high-energy-use building offered substantial roof space for solar panels, but its sloping roof and internal drainage gullies required a carefully engineered installation.

System specification

Following an assessment of the building’s energy consumption and available roof space, DW Energy designed and installed a 109kW commercial solar PV system comprising:

• 270 solar panels
• Two Solis 50kW inverters
• A weather monitoring system

The system generates renewable electricity on site, reducing the amount of energy the business needs to draw from the grid.

Installation approach

The building’s roof presented several technical challenges. Each panel needed to be individually positioned across the sloping roof profile without obstructing the internal drainage gullies.

DW Energy designed the panel layout to maintain effective drainage and incorporated clear access walkways between the panels. This allows engineers to reach the guttering and system equipment safely during future inspections and maintenance.

A weather monitoring system was also installed to support ongoing assessment of the solar system’s performance.

Outcome

The completed installation now generates renewable electricity on site, reducing the business’s dependence on grid energy and supporting its wider carbon-reduction objectives.

The carefully planned layout also preserves access to the roof’s drainage system, helping ensure that the installation remains practical to inspect and maintain over the long term.
