Solar Photo-Voltaic Panels
Gurteen College has installed 168 panels, totalling 50Kw of nominal power in Autumn 2017. Over the course of a year production of daytime electricity is approximately 45000 Kw of, giving the college a saving of over €8,000 per year on purchased electricity.
All of the artificial light in the college, including the farm, is produced using LED lights and smart sensing technology. Over 1200 light bulbs and fittings were changed. This has given savings of between 25% and 75% (depending on the type of fitting replaced) and will lead to a saving on the electricity bill of over €12,000
Rainwater harvesting and water use
The new milking parlour has innovative systems for water conservation and use. Rainwater from the roof is collected and used to wash down the parlour and surrounding yards, thus saving the cost of extracting this water from the college well.
The initial cooling of the milk is done through a heat exchanger with water. This warmed water is then piped through the nearby classroom to provide background heat. Once the heat has been dissipated, the water is then stored in an underground tank for supplying dairy cow field drinkers.
