Project summary: Renew-Able Solutions delivered an integrated renewable-energy system for a commercial site in Scotland, combining 143kWp of rooftop solar PV, 80kWh of battery storage and 24kW of wind generation. The installation was designed as one coordinated system around the building, electrical infrastructure and onsite electricity demand.
This case study records the installed equipment and the practical delivery stages visible in the project photographs and video. The customer’s identity and precise site address are not published. Financial results are not presented as a universal promise: generation, savings and payback depend on measured consumption, tariffs, export arrangements, finance and operating strategy.

The commercial energy challenge
Large commercial sites can use substantial electricity during working hours, making onsite generation attractive where the load profile and available roof area align. The design still has to account for more than panel capacity. Roof condition, structural loading, safe access, cable routes, electrical protection, existing supply arrangements, grid constraints and future energy plans all affect what can be installed.
For this project, solar PV, storage and wind generation were considered as parts of one energy system. The solar array contributes during daylight hours, the wind turbines can generate when local wind conditions permit, and the battery provides flexibility over when suitable onsite generation is used.
System design and documented scope
The rooftop layout comprises 260 modules rated at 550W each. Multiplying the module count by the module rating gives the documented installed capacity of 143kWp. The array was fixed to the profiled-metal roof using a mounting system selected for the roof construction and agreed layout.
The 80kWh battery was paired with Sunsynk hybrid inverters. Battery capacity and inverter power are different measurements: capacity describes the amount of energy that may be stored, while inverter power affects the rate at which electricity can be converted and supplied. Both must be assessed against the site load, renewable generation and operating strategy.
Two 12kW wind turbines provide 24kW of additional installed generation capacity. Wind output is site-specific and depends on wind resource, turbine siting, turbulence and operating conditions; installed capacity is not the same as continuous output.

Commercial rooftop installation
The photographs document the installation sequence on the large profiled-metal roof. Mounting positions were set out before modules were installed, with temporary edge protection and working areas used during construction. Module rows, cable containment and access routes were coordinated across the roof.
Why the load profile matters
A credible commercial solar design starts with electricity consumption. Half-hourly data shows when the site imports electricity, how weekday and weekend demand differ, and whether seasonal operating patterns align with solar generation. This helps estimate how much generated electricity could be used onsite, stored or exported.
More panels do not automatically create the best commercial result. The design should consider self-consumption, export value, battery cycling, inverter capacity, future EV or heating loads and any DNO export restriction. Our guide explains how half-hourly electricity data is used to size commercial solar.
Grid connection and export control
Commercial generation and storage must be assessed under the applicable Distribution Network Operator process. At this scale, the project would normally be considered under Engineering Recommendation G99. Where export capacity is restricted, an approved G100 export-limitation arrangement may form part of the accepted design.
The final connection requirements depend on the network, existing supply and proposed equipment. Read more about commercial solar planning and G99 and commercial export limits and G100.
What the battery contributes
The 80kWh battery gives the site more flexibility over the timing of renewable electricity use. Depending on the commissioned controls and operating requirements, storage may capture suitable surplus generation and supply energy later. It may also interact with time-of-use tariffs where the equipment and commercial strategy allow.
A battery should not be added automatically. The case depends on generation, load shape, available surplus, import and export tariffs, usable capacity, inverter power, warranty limits and expected cycling. See when commercial solar does—and does not—need battery storage.
Delivery and business continuity
Commercial projects require coordinated access, deliveries, lifting, roof safety, exclusion zones and electrical works. The programme should identify which activities can happen while the business operates and whether any planned shutdown is needed for final connection or testing.
Project-specific method statements, sequencing and communication help reduce disruption. Our practical guide covers installing commercial solar around business operations.
How financial performance should be evidenced
This page records installed capacity and equipment scope; it does not publish an unverified savings or payback claim. A financial model should state the annual generation estimate, expected self-consumption, import price, export rate, degradation, maintenance, finance and tax assumptions. Actual performance should later be checked against monitoring and meter data.
Businesses can compare outright purchase with suitable financed arrangements. Where capital expenditure is a barrier, an onsite Power Purchase Agreement may be considered, subject to site, credit, legal and commercial assessment.
What this project demonstrates
- A large commercial roof can accommodate a substantial solar array where structural, access and electrical requirements are satisfied.
- Solar, battery storage and wind generation can be designed as one coordinated system.
- Installed capacity must be distinguished from actual generation and financial return.
- Consumption data, grid requirements and delivery planning are central to the design.
- Photographs, equipment schedules, commissioning records and monitoring data provide the evidence base for an operational case study.
