Solar PV Installation

Accredited Commercial Solar Panel Installers Scotland

Commercial solar is an engineering challenge, not just an electrical one. Greentech Scotland specializes in the design and installation of high-yield commercial solar PV systems for industrial metal roofs, flat roofing, and complex retrofits. From 50kW systems to 1MW+ arrays, we deliver robust, wind-load calculated installations that preserve your roof warranties and withstand the Scottish climate.

Engineered Mounting Solutions

The integrity of your roof is paramount. We utilize lightweight, aerodynamic mounting gear specifically designed for industrial roofing profiles. Our structural engineers calculate wind uplift and static load to ensure every system is safe and compliant.

1

Trapezoidal & Standing Seam

For standard industrial units, we use rail-less rivet racking systems or non-penetrative clamps for standing seam roofs.

Benefit

Drastically reduces roof weight (approx. 12kg/m²) and installation time.

Sealing

EPDM rubber gaskets ensure a 100% watertight seal on all fixings.

2

Flat Roof Ballast Systems

For office blocks and retail units with Single Ply or EPDM membranes, we deploy aerodynamic ballast systems.

Benefit

Non-penetrative installation means no drilling into the waterproof membrane.

Safety

Wind deflectors reduce the amount of ballast weight required, protecting the structural deck.

3

Ground Mounted Arrays

If roof space is limited or structurally compromised, we design ground-mounted solar frames for adjacent land.

Benefit

Ideal for high-consumption manufacturing sites with available land.

Construction

Ram-driven piled frames eliminate the need for concrete foundations, speeding up deployment.

Managing the DNO Connection (G99)

Connecting a commercial system (over 3.68kW) to the grid requires formal permission from the Distribution Network Operator (DNO). This is often the biggest bottleneck in commercial solar projects. We manage the entire G99 application process on your behalf.

1

Load & Fault Level Analysis

We assess your site's Maximum Demand and existing supply capacity to determine if the local grid can accept your export.

2

G99 / G100 Submission

We submit the complex engineering schematics to SP Energy Networks or SSEN. If the grid is constrained, we design a G100 Export Limitation scheme to restrict export while allowing full self-consumption.

3

Witness Testing

Upon completion, we liaise with the DNO engineers to perform the final G99 Witness Test, ensuring the system disconnects safely during a power cut (anti-islanding protection).

Tier-1 Hardware Specification

We do not use unbranded imports. We partner with bankable, Tier-1 manufacturers to ensure your system performs for 25+ years.

High-Efficiency Panels

We install the latest N-Type TopCon solar modules from manufacturers like JA Solar and Trina. These panels offer higher efficiency in low-light conditions (crucial for Scottish winters) and degrade slower than standard PERC panels.

Inverters & Optimisers

The inverter is the brain of the system. We specify commercial units from SolarEdge and Fronius that offer panel-level monitoring. This allows your Facilities Manager to see exactly which panel is underperforming (e.g., due to bird droppings) via a cloud-based app.

Don't Waste Your Generation

Most industrial sites export up to 30% of their generation back to the grid for pennies. By integrating commercial battery storage, you can capture this energy and discharge it during peak tariff windows (4pm - 7pm), avoiding expensive "Red Band" charges.

Resilience & Backup

For critical infrastructure, we can configure battery systems to provide Emergency Power Supply (EPS), keeping essential servers and lighting running during a grid failure.
