Vertical Solar Panels Are Better Than Horizontal Ones in 2024 (We Were Wrong!)
A team of researchers uncovered the reasons behind the unexpected yield gains observed in vertical PV systems compared to horizontal arrays. Their findings reveal that vertical installations maintain significantly lower operating temperatures. These reduced operating temperatures positively impact the operating voltage, thereby enhancing total energy generation, especially in high irradiance conditions.
In standard systems, the increase in voltage due to light is counteracted by the decrease caused by higher operating temperatures under high irradiance conditions. However, in vertical systems, the researchers observed that operating temperatures don't rise as much, allowing the voltage to increase and decrease to balance each other out more effectively.
The group determined that the heat transfer coefficients of vertical panels are nearly double those of horizontal panels. Heat transfer coefficients dictate how heat energy moves between materials and are commonly used, for example, in home insulation.
The researchers also found that the vertical array operates at a temperature difference with respect to ambient that is almost halved, resulting in a 2.5% higher annual energy yield.

Vertical installation might also help with hail damage mitigation. Anybody experienced with using vertical installation in regions where hail storms are more frequent?

@scottmcshannon6821 3 ай бұрын

just install vertical panels where you would put up a fence. solar panel fences are going to be cheaper than good wood fences. may not be in the best location, but since they are doing the job of a fence the installation is basically free.

@Tiraah 2 ай бұрын

Yes, solar panel fences are a good option, but due to weather conditions like rain, snow, wind, etc., if they start getting tilted to the surface, that problem can reduce the lifespan of solar panels, cables etc.

2.5% increase, based in The Netherlands research, is not HUGE. If you change the mounting of solar panels, the best increase in generation is to follow the sun mechanism, which is an estimated 40% increase. And the cost of those mechanisms is not really worth the investment, according to some other researchers.

Sometimes we need to choose what really serves the purpose of a solar energy generation system rather than blindly run after getting maximum energy generation output... Below are 2 scenarios with solar generation systems., The choice is yours :) A. Safe, Steady, Less maintenance, Compromised energy generation (Through parallel to surface horizontally installation setup)... This will hold true for vertical installation setups except for the compromised energy generation part, which is claimed higher in this video, which is great news!) B. Compromised safety, Unsteady, Higher/frequent maintenance, Highest energy generation (Through horizontally tilted to surface installation setup)

That is true. Horizontally fixed panels are less efficient for 2 reasons 1. They heat the surface below them which radiates back and 2. There is less air circulation under the panels.

@mathewpv681 2 ай бұрын

Latitude of Netherlands is 50-54 N. So being vertical there means the panels are at an angle of approximately 52 degrees to the Sun.

I could not agree more. I have power stations because I rent. I physically move my panels throughout the day. In summer here in Fl. I put my panels vertical b/w the hours of 4 pm to 8 pm and 7 am to 11 am. I get more production in those hours because its longer times and panels are much cooler.

There is a building on which the solar panels are vertical along the full height of the building. I noticed that other buildings were following suit soon after. They must have realized that they were more efficient and less maintenance costs. This must have improved their ROI. So instead of installing the panels on the roof, I may want to try placing them vertical in my yard. No need to worry about snow accumulation nor frequent cleaning nor bird droppings. As long as they get enough exposure to the sun, then I should see an improvement over the traditional methods.

Yeah, my system gets snow cover for sometimes weeks at a time here in Michigan, a time when I need the power the most. Bifacial vertical South facing installation is my next system, little chance of snow cover for long, and no hail damage.

Just complimenting the duck curve of horizontal panels to capture more energy during dawn and dusk should be enough to push the optimum arrangement of new PV towards more vertical in areas where horizontal is already well established.

more of a two hump camel output once in the morning and once in the afternoon. should also happen with vertical panels facing east to capture morning and west to capture afternoon sun.. no solar output during the noon time sun. sounds odd .. have seen where some are using the vertical panes to do fences rather than taking up roof tops

I have vertical mount, snow and dirt never sticks rains washes almost all dirt. I can make a 3.6kw array out of 2x4 ,36 of them, only 3 pcs have to be cut and screw together, and you can mount huge panels solo. My 2.8 array makes 780w full overcast. In winter with sun and snow the 2.8 makes 3.5kw, in summer 2.8 makes 1.8kw with no reflective, eg. white rock, but I still generate 2x what I could use per day. South facing, east west is a waste. The albedo gains plus south sun works best for me. Like most of the commenters figured out, how many vertical windows have you seen damaged in a hailstorm? The part of risky costly install of vertical does not apply in my yard.

This might be a better approach especially for Floating Photovoltaics installation in Germany, where panels are allowed to cover a maximum of 15% of the whole lake and at the same time maintain a 40m distance from the shore. With vertical installation, it means that it will still be possible to install panels in small lakes and also compared to horizontal more panels will be installed in a small area.I’m just worried about shading effect that comes with such installation.

@s.lionelmcauley4455 2 ай бұрын

More northern regions dont have the heat related issues and Solar performs much better in our cooler climate. Bifacial panels work very well for those dark winter periods when we are hoping for 2 solar hours a day. Chilled bifacial panels increase harvest when snow reflects light to the back of the panels. Here in South Central Alaska during the Winter Solstice, the ideal panel angle is 7 degrees of tilt. With our long summer days when the sun is high in the sky, we might use a 47 degree tilt.

@ForbiddTV Ай бұрын

Here in Michigan my roof panels are sometimes covered with snow for weeks at a time, a time when I need the power the most. Vertical wouldn't have this issue nearly as much, and if they are bifacial you have the added benefit behind them.

I suspect bifacial vertically mounted solar panels will show up MOSTLY as solar fencing along highways, private property lines, etc. There's PLENTY of unused land where these would make sense. If you combined vertically mounted solar fencing WITH solar roofs even the hottest desert property could have both shade and huge solar power output potential... I don't think we're likely to see TALL walls of solar like is speculated on in the end of the video... Structurally and economically it would make little sense I suspect...But anything under 6' to 8' which is a standard height? Not only plausible but likely...

That is a very bold claim that is trivially simple to validate with an equally trivial "empirical" study. Place two arrays side-by-side and measure wattage from each. Nothing wrong with vertical PV panels, if the owner can justify them, rather than the taxpayer, but as Richard Feynman might say: it doesn't matter what you wish your study says...

I did this same test with one Jinko 400 watt panel, I measured the Voltage and Amps in the exact vertical position, but I found that I got about 3 Amps more if I tilted the panels back toward the ground surface - about 45° (I live at Latitude -27°). I would love if this vertical mounting were true, but is it only true for bifacial panels.
