One year of the photovoltaic system at Alloga in Burgdorf

Monday, 9 December 2019

Sustainability is an integral part of Galenica’s corporate management. The photovoltaic system on the roof of the Alloga building in Burgdorf, which has been in operation for a year, has generated almost 1,280 megawatt hours of green electricity. This equates to the electricity consumption of around 270 homes.

Enhancing resource efficiency, especially in the area of energy consumption, is one of three key sustainability goals of Galenica. It is promoted through a range of measures. For example, Solarstadt Burgdorf AG brought the photovoltaic system on the roof of Alloga into operation on 7 December 2018.

Covering some 8,000 m2, the 4,700 modules, each weighing 18.3 kg, generate 1,280 megawatt hours (MWh) of sustainable electricity per year. In the first 12 months, 240 tonnes of CO2 were therefore saved. The solar installation therefore makes a considerable contribution to sustainable energy production for the town of Burgdorf. Beat Ritler, Managing Director of Solarstadt Burgdorf AG, also confirms this, as the new installation has increased the overall photovoltaic (PV) energy production of Solarstadt Burgdorf AG four-fold.

123,000 litres of heating oil saved

In the first year of operation, 240 tonnes of CO2 emissions were avoided by using the new photovoltaic system at Alloga. This is equivalent to the amount of CO2 that would be emitted by a car over a journey of some 1.6 million km. To remove the same amount of CO2 from the atmosphere over ten years, 20,000 trees would have to be planted. The energy generated annually by the photovoltaic system is equivalent to that of some 123,000 litres of heating oil, 112,000 m3 of gas or 157 tonnes of coal.

At the same time, the solar roof has massively increased the energy efficiency of the building. The sustainable electricity generated covers more than Alloga’s own needs. Because the roof was insulated at the same time as the photovoltaic system was installed, the building has to be cooled less in the summer, which further reduces electricity demand. The reduced heating needs are a further positive effect, as CO2 emissions are lower during the winter months.

Current performance data is available on the Solarstadt Burgdorf AG website.
