In the spring of 2016 Forster completed a 159kWp solar PV installation for the Levenmouth Community Energy Project. 180 panels were fitted on the roof of the Fife Renewables Innovation Centre in Methill. A further 440 panels were installed on unused ground next to East Fife Football Club’s, Bayview stadium. The Levenmouth Community Energy Project aims to be the world’s foremost demonstrator of innovative applications of hydrogen derived from renewable sources. The electricity generated by the panels is being fed into a microgrid, supplying buildings on the adjoining business park. It is also being used for the production of hydrogen for energy storage and hydrogen fueled vehicles. Click here for further information on the project.
The refurbishment of this beautifully designed Grade B Listed church in Aberdeen provided Forster with a perfect opportunity to showcase an outstandingly high level of workmanship. Forster completed the retiling works for main contractor Robertson Construction Eastern. Under the watch of Historic Scotland, 25 panels and 4 conicals (covering a roof area of 409m²) were stripped and re-tiled using Redland (light mixed brindle) Rosemary Clay plain tiles. Particular attention must be drawn to the meticulous skill that went into the large (30m²) conical, where battens were notched and each tile carefully measured and chamfered twice to follow the conical roof profile. This highlights the extreme patience and high skill level of the slater. Other works included the use of lime mortar detailing at the ridges and abutments.
The in-roof solar installation of the Crown Office, Procurator Fiscal’s Office provided Forster with the ideal opportunity to showcase their integrated roofing and solar service on a sensitive, fully operational building in central Glasgow.
An inspection of the roof was carried out prior to the solar installation and on consideration of its age and relatively short remaining life expectancy, a decision was made to incorporate the renewal of the entire 1,800m² roof covering into the project. As the roof structure was not designed to withstand the weight of natural slate, the existing slate-composite roof was stripped and 25,000 Redland Cambrian ‘Slate Grey’ tiles were fitted.
Black panels and an in-roof fixing system were selected to integrate and sensitively blend the solar arrays in with the new roof finish. A total of 96 (270Wp) panels were installed across the two most suitable roof panels. The clean, self-generated solar energy is providing power to the offices and helping to reduce the carbon footprint of the building.
During scaffold erection, out of hours working was incorporated into the programme to minimise the disruption to those working within this busy building. Also as the scaffold was being erected in close proximity to street lighting on an exceptionally busy public footpath, the street lighting had to be shut off during site operational hours.
The design and operation of the building restricted the positioning of hoisting equipment to a single location. This meant that additional time for handballing materials had to be accounted for within the programme of works.
Our high standards of health and safety were again required to ensure the safety of all involved and impacted by the works, including the HSE prosecutor, whose office was in this busy four story building.
The National Trust for Scotland’s beautifully green Pitmedden Garden in Aberdeenshire is now even greener with the introduction of solar PV panels. Installed on the roof of the Gardeners storage shed, the PV array generates enough energy to power the Museum of Farming Life and all other buildings at the stunning Aberdeenshire garden. In fact the 115 panel array generates over 25,000kWh of electricity a year, enough electricity to power 6 homes. In addition the site will reduce it’s CO² emissions by 11 tonnes per year through their PV installation.
The National Trust for Scotland has established a ‘Preferred PV Partner’ arrangement with us to help reduce their electricity costs and cut their fossil fuel use & carbon emissions. We have been working with the Trust since the beginning of 2014 – identifying suitable sites, as well as designing and installing PV systems at a number of locations across Scotland. These include Inverewe Garden & Estate and The House of Dun.
The striking setting and impressive design of the Grade B listed Doo’cot Park pavilion in Perth combined with its historical significance created the perfect context for Forster to demonstrate their skills in heritage tiling.
The pavilion was designed by Smart, Stewart and Mitchell and built between 1924/1925. The Gannochy Trust was later founded in 1937 by Arthur, known as A K Bell, for charitable and public purposes as a direct result of his family’s successful distilling business. In addition to the cricket ground A K built the innovative Gannochy housing estate between 1925 and 1932 to provide high quality rented accommodation for the people of Perth.
The Sandtoft Heritage Service provided an original specification for the contract. Works to the cricket pavilion involved stripping the existing tile and retiling with Sandtoft Greenwood handmade clay pantiles. Close attention to detail was required throughout but particularly to the facetted bell shaped tower. Locally sourced larch bark timber was utilised to provide barge and fascia detailing. Traditional lime mortar methods were adopted in keeping with the striking design. All leadwork was replaced to meet the highest required standards.
This re-slating and in-roof solar PV installation on the modest ‘Bunkhouse’ within the grounds of the National Trust for Scotland House of Dun demonstrates Forster’s ability to sensitively integrate solar PV into slated roofs.
Following consultation with Forster, the Trust selected the ‘EasyRoof’ mounting system and black framed panels to sensitively blend in with the house. The 15 panel (3.75kWp) PV installation provides power for the electric heating, showers and all other appliances, particularly during the summer months, when the house is more frequently occupied by students. The full south facing roof elevation was utilised to maximise the PV power potential.
The roof had a bell-cast, which presented a challenge to the installation team. This was overcome by the addition of support beneath the bottom row of panels.
This project is part of a ‘Preferred PV Partner’ arrangement with the National Trust for Scotland to help reduce their electricity costs and cut their fossil fuel use and carbon emissions. The Trust selected Forster’s based on their roofing and project management experience, particularly their expertise with working on historically sensitive and occupied buildings. Forster has been working with the Trust since the beginning of 2014 – identifying suitable sites, as well as designing and installing PV systems at a number of locations across Scotland. These include Inverewe Garden & Estate and Pitmedden Garden.
Many farms and other agricultural related businesses are coming under increased pressure from their supply chain to become greener by finding ways to reduce their carbon footprint.
One such business is North East daffodil and seed potato co-operative Grampian Growers, who has turned to solar PV to generate its own supply of clean electricity. The Montrose based co-operative grow, store and process daffodil bulbs, flowers and seed potatoes mainly for export to America, mainland Europe and North Africa.
“We were also keen to take control of our energy costs, by reducing the amount of electricity we buy in. PV presented us with the perfect opportunity to do just that, by utilising the available roof space on the site” added Production Manager, Fergus Kelly.
The 593 panel 148.25kWp PV array was installed over two large south facing composite roofs by Forster Energy, Scotland’s leading supplier of roof-top solar PV for farmers. An initial 50kWp array was installed in June to secure a higher feed in tariff rate. A further 98.25kWp was added in September following approval of planning permission.
Constraints on grid capacity place a limit on the amount of electricity Grampian Growers can export. Therefore a special export control system was installed to regulate the amount of electricity that is fed into the grid. “Increased pressure on grid capacity has led to a growing number of instances of export restrictions being placed on renewable energy generators. For this reason export control systems like this are becoming more widely used” explained Stephen Ward, Forster’s Design Engineer.
The new PV system is projected to have paid for itself within seven years and is set to provide a 19% annual return on the initial investment through energy savings and feed in and export tariff payments.
