Investments in clean energy rank among the most sustainable in the world. EVVA has set up its own photovoltaic (PV) systems at several locations in order to generate at least a part of its energy requirements.
Photovoltaics EVVA Vienna
The 680 solar panels on the roofs of the headquarters have been supplying EVVA’s main production facility with environmentally friendly energy since 2013. We started 2013 with 340 panels, so over 300 panels have been added since 2015. The system is one of the largest commercial photovoltaic areas in Austria. It currently generates 200,000 kWh per year, as much about 40 single-family home can generate with their photovoltaic systems..
EVVA photovoltaics is a pioneer in the district, and many local companies have followed suit and also installed their own systems. Our PV system generated over 1 gigawatt hour (= 1,000,000 kWh) between 2015 and 2019. We originally expected 15% less, i.e. the plant is more efficient than expected.
The expansion of the headquarters in Wittmayergasse in Vienna should be completed by 2021. Another PV system on the building is already planned – on the maximum possible roof area. These new panels will have 50% more power than the previous ones, which are already 6-7 years old, thanks to the fact that PV technology has advanced a lot. Our own total energy production is thus increased by 50,000 kWh/year or 25%. In summer, the new extension's PV system will provide all the hot water needed by the building. The cost of the existing PV system will be amortised by 2025, the cost of the new PV system on the extension by 2030.
Our photovoltaics in Vienna will then cover around 5% of EVVA Vienna’s electricity requirements. This allows us to maintain the base load in the event of a total power failure. The assembly of the access solutions can also be continued manually for a period of time
EVVA photovoltaics generate a total of 250,000 kWh of clean energy per year (which corresponds to the consumption of approx. 50 single-family households)! Our PV system saves approx. 20-25,000 euros per year in energy costs and the environment 65 tonnes of CO² emissions
Photovoltaics EVVA Italy
Our branch in Villorba, Italy, was modernised in 2013, and since then a PV system has been performing its valuable service on the rooftops. It delivers 38,000 kWh per year.
Photovoltaics EVVA Netherlands
The PV system at the EVVA site in Hengelo has been in operation since December 2019. The 180 panels provide a total output of around 57,000 kWh (60.3 kWp) per year and thus cover around half of the branch’s energy requirements.
"At the end of 2019, we restructured our EVVA Netherlands building and also invested in photovoltaics. The system produces around 50% of our energy requirements and has already saved 22,240 kg of CO² emissions," explains Rick Baayens, Sales Manager at EVVA Netherlands.
A photovoltaic system for the new EVVA building in Tišnov in the Czech Republic is currently being analysed and planned.
