University of Kent
17.5 kWp Solar PV systems installed across multiple homes in West Sussex.
Ecolution installed a 67.5 kWp flat roof solar PV system on the Templeman Library building in Canterbury for the University of Kent in 2015.
The University of Kent, formerly the University of Kent at Canterbury, is a public research university, founded in 1965. In 2014 they were ranked in the top 20 universities in the UK by ‘The Guardian University Guide’.
The University has over 21,000 full-time students who regularly access to the library facilities, which during term time are open 100 hours per week. The Templeman Library is one of three of the Universities libraries built in 1960’s, which are all in regular use by both students and lecturers. Collectively the libraries not only provide students with over one million books, periodicals and journals but also power 720 fixed PC’s and over 80 laptops and netbooks which are in constant use. The Templeman Library has additional requirements for electricity including a café, group study rooms and video facilities. Due to the high volume of people attending each day and the amount of electronic devices plugged into the mains this was a building with high energy usage during daylight hours that could really benefit from a solar PV system to cut energy expenditure.
The University ran a formal tender process and Ecolution were awarded the installation including monitoring and maintenance for this project. The products used were CSUN polycrystalline modules and Growatt 1800 UE inverters.
During installation it became apparent that there was asbestos in the building’s risers, which in our original designs was where the cables from the roof to the inverters would run through. However to save the client time and money our team designed an external cable run to avoid these areas.
The library has a high daylight amount of lighting demand so a solar PV system was a clear solution for not only reducing the university’s energy bills but also provides an income via the feed-in tariff which incentivises renewable energy generation. It is predicted that 100% of the renewable electricity generated by the Solar PV system will be used by the building itself meaning they are gaining the maximum benefit from the installation.
The system is producing approximately 68,378 kWh of free electricity per year, and in doing so offsets over 36 tonnes of carbon dioxide.
