Solar Panels to Provide Renewable Energy for The
Brook School
The Brook School is an infant school for children aged 4-7 with a nursery
attachment serving Maidenbower in West Sussex. We provide high quality
education addressing not only the child's academic needs but also their
emotional, physical and spiritual well being.
We have achieved dyslexia friendly, Healthy Schools and Silver EGo School
status, plus the Basic Skills Quality Mark and our Travel Plan Mark level 1. The
school development plan focuses on achieving green flag eco-status and working
towards the government's 2020 sustainable schools target.
We aim to develop creative confident, reflective learners who will grow into
responsible and globally aware adults.
The Project
The Brook School and Nursery proposes to install 56 modules of Solar
Photovoltaics panels on its south-east facing roof. This will give an annual yield
of 6,985 kWh and an annual carbon offset of 3,968 kg. This is an ambitious
target, but once achieved would send a positive message of sustainability to both
children and our local community.
The school's building is solely used to provide high quality education for children
aged 4-7 years, (including 3 year olds in the Nursery), addressing not only the
children's academic needs but also their emotional, physical and spiritual
wellbeing.
Technically we have an ideal roof for solar panels due to its large surface area
and slightly slanted direction. The panels would be in optimum position to utilise
the sun from sunrise to sunset.
Alms of the Project
The aims of this project are focused on increasing knowledge and understanding
of sustainability. The children at the Brook will have the opportunity to gain this
knowledge through the curriculum which follows the Reduce, Reuse, Recycle
concept. The installation of solar panels will underpin this concept and su ort

learning for the children, their families and the wider school and community networks.
Other benefits include the increased C02 offset (this project predicts a carbon offset of 3,968 kg), contribution to sustainable living, reduced energy cost, move towards the governments 2020 sustainable schools target, monitoring and sharing real time data and utilising the schools community stature to promote sustainability for the future.
Project Beneficiaries
There are several educational benefits for this project.
• Children who attend the Brook School (2500 in 25years) will develop their understanding regarding sustainability This will affect their future outlook and life choices.
• The PV panels will send a strong message of our commitment to conservation and sustainability to the community. Real-time data will be available on our website.
• We are part of a schools network where best practice is shared. Other schools will be motivated to develop their sustainabirity as we were when we visited a school with different microgeneration technologies.
Community Involvement
Over the last year the school has been working hard to achieve the Green Flag Status. We have achieved our Silver Award and are now in the process of applying for our Green flag. through this process we have involved all the children and their families, including a reduce your carbon footprint project, recycling and other "green" initiatives. Our website has its own green pages (http:I/www. brook.w-sussex.sch uklcelebration/EcoGang htm) which updates families and the local communities on our green projects. There are monthly newsletters sent home which remind parents to visit these pages and updates them on our plans to go greener.
In addition, this solar panel project has been discussed at Governors meetings to gain consent and support.
We have also been in discussion with Henry Smith, Leader of the West Sussex County Council, and Jennifer Millar-Smitli Maidenbower Councillor who have offered us their full support with this initiative.
Expected Visual Effects on The Brook School
The Brook School is a single story long thin building as demonstrated in the
picture below:
The school has a very low slanted roof and the solar panels will be installed into
the centre of the schools roof. See picture below:
w.s.C.C. 11MM2 COUN) .1
There is a slightly elevated public footpath which runs parallel to the school as seen from the photo below:
The solar panels wdl be visible due to their dark blue colour, although as a school we want the panels to be seen so that we can share best practice and involve the children in their production of energy.
Conclusion
tr
This project bid details our plans to install 56 PV panels to our School; we want
to use this project to educate our children and community about sustainability.
We truly believe that as a school in our area we are in the ideal position to bring
about change in people's actions and thoughts. We ask that you consider our proposal favorably and help us to achieve our objectives.

Metal Roofing Bolt-on PV Support System
Design Solar Technologies have developed light weight aluminium bolt on roof support framework systems that can be rapidly adapted for local conditions.
These systems allow standard photovoltalc modules to be attached to a wide variety of roof types easily and securely. Solar Technologies provides the appropriate roof anchor points for all metal roof types and insulated panels, such as standing seam, profiled metal roofing and various alternative designs. By combining these with different Installation options, the perfect fixing method is available for almost every roof-mounted installation.
Suitable for retro-fitting to new and existing roofs, the system is held in place using various fixing methods, from seam clips to Tek-screw, which we ensure maintains roof integrity.
Any roof penetration's that are required are always achieved while providing water-proof characteristics of the roof.
Installation Solar Tethnologies Installation teams are
fully trained with over 16 years experience in
PV systems installation.
Quality Solar Technologies have the design experience and the installation knowledge to engineer a bespoke solution If required. With over 16 years experience, we have installed bolt-on systems on nearly all types of roof and fixed to many of the standard building materials used today.
Wind loading and construction calculations are completed for each site to ensure that building regulations are met.
Health & Safety Before work commences a risk assessment is
carried out to determine the Health and Safety requirements. Method statements are then developed to ensure that the work can
be completed in a safe and timely manner.
Solar Technologies is fully conversant with the requirements of CDM regulations and can
operate as principle contractor or sub
contractor

Electrical Installation
Design Installations provided by Solar Technologies will meet the requirements of 65 7671 and
the second edition of the Dli PV Installation Guide.
DC Installation Photovoltaic modules are electrIcally connected in series to form 'strings' and then in parallel combinations compatible with the chosen inverters.
Double insulated cables feed the electrical power from the array strings to array marshalling boxes (AMBs) where individual strings can be paralleled as required. Cable
interconnections are made via double insulated connectors with an IP rating of 1P67
(as defined in 65 EN 60529:1992).
DC cables should generally be kept as short as possible.
AC Installation Solar Technologies will only install Inverters certified as G83/1 compliant for use in the UK. The certification can be supplied if requested.
Inverters are generally Installed alongside the AMB's and individual AC Isolators in a
suitable space (e.g. roof space, plant room or extemally etc.).
Access to the equipment is important for commissioning and maintenance although for general use access should be restricted to qualified personnel.
For externally mounted equipment the location should be chosen to avoid dIrect sunlight falling onto equipment enclosures.
For internally mounted equipment approximately 8% of the electrical energy generated by the PV array will be dissipated by the inverters as heat and it is Important that equipment rooms are ventilated to allow excess heat to escape.
For connection under 659/1 an additional control enclosure will be required for the protection relay and its associated contactor. The protection relay will provide protection against over/under voltage, over/under frequency and loss of mains. On re- established mains systems the PV system will auto-reset and synchronise without manual Intervention,
Metering The connection to the distribution board will include a generation meter that meets the requirement of OFGEM.
