New research says vertical solar panels have improved performance

Research shows the need for storage decreases if the majority of the solar capacity is installed vertically in an east-west orientation.

Researchers in Germany claim vertical solar panels may be better than horizontal solar panels. Typically, solar panels are mounted horizontally and oriented toward the south to get maximum exposure to the sun as it travels across the sky. Instead of lying flat, they are angled at between 20 and 35 degrees, depending on how far from the Equator they are located. There are complex mathematical formulas that tell solar farm developers the precise angle the panels should be mounted at in Pensacola, Peoria, or Penticton. There are tracking systems that can move the panels during the day to follow the sun, but they are expensive and need regular maintenance.

But what if conventional wisdom is wrong? Researchers at Leipzig University of Applied Sciences claim that mounting bifacial solar panels with one side facing east and the other facing west would produce more renewable electricity and reduce one of the side effects of traditional solar energy farms — an abundance of electricity at midday and not enough in the morning or afternoon. Their study was published in the August, 2022 edition of the journal Smart Energy.
