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 December: Cloudy winter weather. Under these conditions vertical solar installations give almost the same yield as a conventional flat roof 10-degree tilt installation.
6-12 December: Sunny days with little or no snow cover. Under these conditions, the yield of vertical bifacial can be very good. For these days, the VPV yield is about 450% higher than the conventional installation.
13-18 December: Snow showers with some sun in between. The vertical solar installation gives good yields while the conventional installation is quickly covered with snow and “light’s out”.
We are excited to go into our first winter, now with several operational research installations with different climates and/or configurations. We will certainly learn a lot!
Energy yield from vertically mounted bifacial solar panels More energy in the morning and in the evening with V-bifiGet 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…Keep reading
24 hours of solar power! Imagine if a solar power installation could produce electricity 24/7! This week at our research installation in Tromsø, Norway we had 24 hours of continuous production, taking advantage of the midnight sun! At one of Posten Norway’s distribution centers, we have commissioned a research installation with 14 Over Easy’s patent…Keep reading
Now you can retrofit your green roof with a solar energy system With more and more cities around the world changing the building code and regulation to better adapt to the climate conditions. The cities must combine green roofs, systems for delaying water and energy production to conform to the new expectations. Currently you must…Keep reading
