Solar Case Studies
Our roof integrated solar is not just for domestic properties, it’s suitable for commercial and industrial roofs as well.
This system, designed for Eagle New Energy, provides power for an energy intensive building, saving on future operating costs. . With the FIT rates and savings on energy bills, the initial costs will easily be covered in less than 10 years. What other roofing material can achieve that?

The GB-Sol design engineers produced CAD drawings of the various array layouts and flashings so Green Tech could plan for a straightforward installations.
The RIS system fits onto the standard roof battens and seals the roof so the developer saves on the costs of the tiles for the area of the array.
By fitting the system directly to the battens the builder does not have to make any special allowances for the installation of the array. Once installed the roofer tiles around the array as they would a roof light or dormer window.
The result is an aesthetic, sympathetic, compliment to the architectural design.

Lewis House — East/West Array
Lewis House is owned by Bath and North East Somerset Council. The roof was challenging to access and could only withstand loading in certain areas. GB-Sol and their installation subcontractor SRS were selected for this job because of their record of difficult and unusual solar PV roofing projects.
152 panels were mounted on the roof providing 38 kWp of power to help run their newly installed low energy lighting system.
The array utilised the FS10 Renusol mounting system designed to provide a longer more even exposure to daylight so that the energy generated peaks less during the middle of the day.

GB-Sol installed several different PV- battery example systems in social housing. This is being monitored and the data analysed by Cardiff University Architecture Dept.
Systems were designed for a range of occupancy, and comprised from 2kWh to 20kWh storage capacity. By storing sufficient energy for evening use, the self consumption level increased dramatically, thus reducing the fuel poverty level of the occupants to a much greater ex-tent than achieved just by PV generation.
Landlord concerns regarding battery safety and security were addressed and successfully overcome.
Solar Photovoltaic Roof for Area of Outstanding Natural Beauty
This beautiful architect designed eco-house is on an elevated and exposed coastal location above St. Ives, Cornwall. The site is within an Area of Outstanding Natural Beauty so it was important for the architect to select a practical, weatherproof and aesthetic solution, as well as being visually acceptable by the local planning authorities.
The GB-Sol RIS system was chosen as it met all the design criteria. Our company’s ability to produce individual solar panels in the necessary triangular and trapezoidal shapes required by the design was a paramount factor.

Arnold Gilpin Associates – Fully Integrated Solar Roof
The GB-Sol design engineer produced CAD drawings of the construction and PV panels with dimensions adjusted to meet the architects roof dimensions providing a full width, weatherproof array.
Further liaison enabled us to develop specific flashings adapted from our standard designs to match the overall roof design. The result is an aesthetic, sympathetic, compliment to the architectural design.
The north elevation has a traditional roof covering but the rear south facing elevation used the GB-Sol RIS system to provide a complete solar roof.

GB-Sol completed the manufacture, design and installation of a complex PV system for Trinity House, the UK lighthouse authority.
Having supplied General Lighthouse Authority for England, Wales and the Channel Islands with solar panels for their buoys, monitoring stations, lightvessels and lighthouses GB-Sol were proud to be selected to superimpose the 75kW array onto the curved buoy maintenance building at Harwich.
The electrical layout was complex to maximise the output despite the differing angles of the roof and the shading from the chimneys. The mounting system layout had to contend with existing roof lights and had to leave room for man-safe mounts for future access.

Rhonda Cynon Taff – Solarisation of Community Buildings
GB-Sol were selected through the council’s tendering process to supply and install 30 kW Overtile PV systems to seven Rhonda Cynon Taff Care Homes. Their aim was to supplement power usage and as part of their commitment to renewable energy.
Every system was equipped with a monitoring system that will show the public the amount of energy being generated, totaled from the start of generation and the amount of CO² that has been saved.

Refurbishment Project – Little Chew
In a picturesque Oxfordshire village this pleasant property was being fully restored by a local builder. They employed the GB-Sol accredited Installer Next Generation Renewable Energy (NGRE) to provide a Photovoltaic system as part of the rebuild of the old garage roof.
The BRE tested RIS system occupies a significant amount of the roof so saving the cost of slates that the array replaced.
The system is connected to the grid so providing the owner with a Feed in Tariff that will provide an attractive return on the investment as well as a low carbon footprint.

42 RIS systems for a new Housing Association Development
As all the roofs were slate, an aesthetically low impact Roof Integrated System (RIS) was specified. Jeff Way needed high quality arrays from a reliable company that would work in partnership with them to deliver a first class service to both builder and architect.
The builders, wanted to exceed the minimum requirements to enable compliance with SAP. Their vision was to enable the homeowner to produce good amounts of solar power across each of the new homes with arrays that were above the standard specification. The project was completed seamlessly and the effect was stunning; 42 arrays were successfully installed across the properties.
Herts CC decided to maximise the use of their County Hall roof and further enhance their low carbon activity. Miguel Diez contacted GBSol when he decided to use the Renusol Console system to maximise the use of the roof area. After a technical discussion with a GB-Sol engineer he was convinced this system solved the Herts CC requirements.
Originally, the specification called for 126 panels but by increasing the panel wattage and by using the Console system they achieved the required 24kW and managed to fit it within the available un-shaded roof space. Using 96 Consoles they could strategically space the panels to maximise accessibility and output without using more complex mounting systems or penetrating the roof membrane.

The residential care home has an ‘L’shaped roof with two large flat southerly facing aspects (1 x South East, 1 x South West). Maintaining the original roof line we installed two large solar PV arrays within the roof areas, replacing roof tiles with solar PV panels in the roof integrated ‘RIS’ mounting frame.
The care home operates its own kitchens, laundries and lifts, in addition to needing power for the staff and residents TVs, computers, radios, lights etc. The care home now only really uses power from the grid at night and on dull days.
Over the course of the year, the care home will be close to generating as much power from the roof as is used inside the building. The integrated PV roof was specified to provide an aesthetic solution to renewable on-site generation.
