Case Study

Edinburgh City Council Solar Co-Op


Client: Edinburgh City Council Solar Co-Op

Project: Community Energy Framework

Contract Value: £1.5 Million

Total Installed Capacity: 1.5MW


Emtec Energy were appointed as Principal Contractor to install 1.5MW of Solar PV across 25 council owned properties consisting of Primary, Secondary and Special Needs Schools, as well as Leisure and Community Centres. The 8-month project, completed between February and September 2016, is expected to produce an annual yield of 1,120,000kWh which equates to a reduction of 553,280kg of CO₂ emissions a year.

Our Design Engineers carried out detailed site surveys on all sites reporting on roof, structural, asbestos and electrical particulars.  Measurements and manufacturer details of roof types were taken and factored into the design of the solar PV arrays.  Roof dilapidation reports were also compiled based on the condition of the roofs at each site. These reports were issued to the Council stating any roof areas which would require remedial repairs prior to the commencement of works.

Individual designs were created for each site using PV Sol Professional Solar PV modelling software and AutoCAD, which would form part of the individual Construction Phase Plans for each site.


Site Specific Case Study


Location: Currie High School

System Size: 133.38kWp

Approximate Annual Yield: 98,839kWh

Annual CO₂ Reductions: 48,826kg


Emtec Energy were contracted to install a 133.38kW Solar Photovoltaic system for Currie High School in Edinburgh. This included the design, installation and maintenance of the PV system, which was completed in September 2016.

The system is comprised of 513 Seraphim 260W PV modules, generating an annual expected yield of 98,839kWh based on PVSol modelling of the array and site location.

Due to the size of the installation and the available roof space, there are seven arrays located on the roof areas of the school.  The system is connected to eight Fronius 3-phase inverters, which are mounted in various locations throughout the school. These inverters range from 10kW to 20kW, with five inverters mounted externally and three internally.

This installation presented several barriers to installation. As the system was installed across multiple roofs, this required additional surveys and analysis to ensure maximum efficiency was reached. The school also acts as a community centre outside of school hours, this means the building was in use seven days a week and often busy throughout the whole day. This limited the hours available for operation as we were only allowed access to particular areas at certain times. Through daily meetings and collaboration with the building manager, we discussed our installation plans for the day and agreed upon terms to ensure this ran smoothly. With processes in place, we managed to complete this project with ease and to the delight of those involved in the project.

“Emtec put in a competitive bid that provided us with what we required.  I’m happy to say that Emtec delivered on-time in often challenging circumstances and to a tight deadline.  Many of our schools commented on how good Emtec were to have onsite”

Paul Phare, Director of Edinburgh Community Solar Co-operative


“Emtec completed a complex project to fit 133kW of solar PV panels to a number of roofs in Currie Community High School.  Emtec worked in a professional manner from day one and completed the project in line with what was agreed with the school at the outset.

Fitment of a considerable number of solar panels with pupils working normally in classrooms required careful management, close adherence to procedures, strict safety standards and daily communications with a number of school staff.  A conscientious approach by Emtec throughout the project and a professional approach by all Emtec operatives ensured that teachers and pupils were unaffected by these works.

Particular credit should be given to Gary Norwood, Emtec Site Supervisor, for the success of this project.”
