Amersham & Wycombe College (Chesham Campus)
Amersham & Wycombe College decided to install PV onto the roof of a building on their Chesham campus as the college were offering installer training courses which would lead to the City & Guilds certificate 2372 "Installing & Testing Photovoltaic (PV) Systems". Amersham & Wycombe College felt that lecturers and students would find it beneficial having a local system which students could fully relate to.
The project was grant funded under Phase 2 of the Low Carbon Building Programme and part funded by Amersham & Wycombe College. Once the funding had been agreed the college identified Photon Energy as the preferred installer to install the system. Due to the campus having a flat roof, a bespoke mounting system was installed, along the centre of the roof running east to west where a channel of A-shaped rooflights allows natural daylight into the corridor below.
Historically, the corridor suffered from overheating in the summer, so the shading which was created from the PV modules was welcomed.
The installation took 2 days to install and 1 day to commission. To date, the installation has helped to provide students with a greater awareness of the benefits of PV and sound knowledge of the installation process.

Hawthorns School, Wokingham, Berkshire
The grid connected roof mounted PV has been installed and commissioned by Ardenham Energy Ltd on the Hawthorns School in Wokingham after development work by TV Energy and Wokingham Borough Council.
The installation was undertaken following the award of a Low Carbon Building Programme Phase 1 Grant and planning approval by Wokingham Borough Council in September 07. The electricity generated is synchronised with the grid supply via an inverter and will be used to supply clean energy to the building as well as exporting to the grid for use elsewhere when there is more energy produced than is necessary.
The 2kWp array is almost silent in operation and will generate around 1600kWh of greenhouse gas free electricity each year, The installation includes a display in the reception area which outlines real time energy production as well as cumulative kWh and CO2 savings.

West Oxford Community Centre, Oxfordshire
The grid connected roof mounted PV Array has been installed by Ardenham Energy Ltd and commissioned by South Facing at the West Oxford Community Centre on the Botley Road in Oxford. Alternergy Ltd was the European distributor chosen to supply all the hardware for the system including the modules, inverters and mounting frames. Sharp modules were chosen as the most cost effective and high quality solution available on the market.
The installation was undertaken following the award of a Low Carbon Building Programme Phase 1 Grant, and planning approval by Oxford City Council in April 2007. The electricity generated is synchronised with the grid supply via an inverter and will be used to supply clean energy to the property, as well as exporting to the grid for use elsewhere when there is more energy produced than is needed in the property.
The 5 kWp array is almost silent in operation and will generate around 4,000 (kWh) of greenhouse gas free electricity each year.
The installation took 3 days to complete and comprises:-
- Display showing cumulative kWh and instantaneous Watts in Reception
- 3 phase pulsed kWh Meter
- DC and AC switchgear
Supplier: Alternergy Ltd
Installer: Ardenham Energy

MANCAT, Manchester
This Sixth form college features Sharp modules on a two-storey solar facade. Inspired by the installation at the CIS Tower, the south facade of the new building is clad in a striking monolithic array of solar PV modules. Taking advantage of the building's flat roof, rows of PV modules crown the building providing further clean energy.
A total of 482 80W SHARP polycrystalline modules are used in the cladding design with a further 178 165W SHARP modules providing the roof top power system.

Environment Agency, Wallingford, Oxfordshire
Sharp 80W modules as the most appropriate photovoltaic (PV) technology for this application. This high efficiency modular technology was then fitted into specially designed metal frames to form louvres and in turn a PV brise-soleil. The solar arrays installed are made up of a total of 316 Sharp 80W PV modules designed and supplied by solarcentury.
The PV modules form a brise-soleil canopy on the concave south façade, the canopy formed by fixing the PV louvres to existing steel beams. PV louvres were created by fixing the modules and the aluminium cowling to bespoke telescopic spindles on ground, which were then lifted into position.
Energy savings from the solar louvres, complemented by the energy efficient design of the building, will meet around 20% of the building’s annual demand for electricity.
