Energy yield from vertically mounted bifacial solar panels
More energy in the morning and in the evening with V-bifi
Get two energy production peaks each day rather than one with east-west mounted V-bifi units from Over Easy!
Mounted so the sunlight hits the panels on the east side in the morning and on the west side in the afternoon, you get one peak for the morning coffee and one for the evening activities. The figures displayed above show the energy production profile during a sunny summer day from one of our installations outside Oslo in Norway. As you can see, the energy production profile gives high yields in the morning and evening, and a total yield of 27% more energy during the day for east-west orientation. The energy also comes at a valuable time to stabilize the local electricity grid. The south-north installation has a bit lower yield than the conventional panels, but as can be seen in the following, this is more than compensated for by higher yields during the winter months.
A different seasonal variation
How high energy production you will have from V-bifi over the year, depends strongly on location and the local climate. Over Easy Solar is running a research project, together with IFE Institute for Energy Technology and Fraunhofer ISE (vertical.solar), where we are mounting installations to collect data from different latitudes and climate conditions. In addition to our installations in and around Oslo on different surfaces. (Asphalt, White Roof and Green Roof) we have a installation in Tromsø (North of Norway) up and running. This fall Bergen (Norway), York (UK) and Valencia (Spain), among others, is planned. We are looking forward to getting more performance data and discover new benefits from the Over Easy technology.

What about snow, your panels don’t work in the winter, do they?
What about snow, your panels don’t work in the winter, do they? Many people we have met have asked the question: What about snow, your panels don’t work in the winter, do they? Let’s have a quick look at the situation right now: Bergen 13 March 2023: 5 cm snow on the ground: Pilot installation…Keep reading
VPV (Vertical PV) in winter conditions, Oslo Norway
VPV (Vertical PV) in winter conditions, Oslo Norway Many of our customers ask how vertical solar panels work during the wintertime. Over the last two weeks, we’ve had some nice winter weather in Oslo that beautifully demonstrates how this works. From the data we share in the graph here, we can make some interesting observations:1-5…Keep reading
