What are the vertical lines on photovoltaic panels
The VBPV system, characterized by its vertical orientation and the use of high-efficiency Heterojunction cells, introduces a novel concept diverging from traditional solar panel installations.

Using Solar Angles to Predict the Sun’s Location. On one day every year, called the equinox, the sun is positioned directly above our planet’s equator. On this day, the angle between a line that points to the sun and a line that points straight up (vertical) exactly matches the latitude of the place you are standing.
The vertical installation exhibited a ~ 1678 kWh/kWp performance ratio, retaining ~82% of the tilted installation energy yield. The results underscore the feasibility and advantages of employing vertically installed bifacial photovoltaic panels in residential settings, particularly in limited areas.
The east/west vertical installation shown below will yield up to a 90% backside energy gain compared to a standard module. Shadowing practices still apply for vertical modules.
h is the height of the panel line; the vertical height, from the top point on the ground. tanH is the tangent of the solar angle in the most unfavorable month in our latitude. cosA is the cosine of the solar azimuth in the worst month.
