The theory of solar cells explains the process by which light energy in photons is converted into electric current when the photons strike a suitable semiconductor device. The theoretical studies are of practical use because they predict the fundamental limits of a solar cell, and give guidance on the phenomena that contribute to losses and solar cell efficiency.

horizonal vs vertical panel orientation
FYI - If I go with panels that are 42 by 84 (I rounded up) it does not seem to matter about the layout - as it would fit in the same footprint. Example: Horizonal would be 3 panels across and 4 panels high. Vertical would be 6 panels across and 2 panels high. Both of them would be 21'' across and 14'' high give or take for a total of 12 panels.
How to stop cell contents being moved when I scroll vertically
When I use the scroll wheel on a mouse to scroll up and down a spreadsheet in Calc, the contents of the cell that the cursor is in get moved around with the scroll. Unless I notice and scroll them back to where they should be, then the contents of that cell get left in a random row. Sounds odd, I know, but ''unrequested data randomization'' is not really a function I''m
Vertical vs. Horizontal Solar Panels: Does Orientation Matter?

Solar Cells: Basics
The exact behaviour of solar cell efficiency η in function of light intensity cannot be predicted in a general manner, but depends (as stated above) on solar cell type, solar cell design, and solar cell fabrication process. Amorphous silicon solar cells have, in most cases, a better efficiency at very low light intensities than wafer-based crystalline silicon solar cells: for

6 FAQs about [Solar cell does not move vertically]
How effective is vertical alignment in solar power conversion?
Vertical alignment persists at the solar cell level, giving rise to a record 9.4% power conversion efficiency with a 1.4 V open circuit voltage, the highest reported for a 2 eV wide band gap device.
What is the theory of solar cells?
The theory of solar cells explains the process by which light energy in photons is converted into electric current when the photons strike a suitable semiconductor device.
How do solar cells work?
The electronic structure of the materials is very important for the process to work, and often silicon incorporating small amounts of boron or phosphorus is used in different layers. An array of solar cells converts solar energy into a usable amount of direct current (DC) electricity.
Why do solar cells have a special structure?
Due to their special structure and the materials in solar cells, the electrons are only allowed to move in a single direction. The electronic structure of the materials is very important for the process to work, and often silicon incorporating small amounts of boron or phosphorus is used in different layers.
What causes charge carrier motion & separation in a solar cell?
There are two causes of charge carrier motion and separation in a solar cell: diffusion of carriers from zones of higher carrier concentration to zones of lower carrier concentration (following a gradient of chemical potential). These two "forces" may work one against the other at any given point in the cell.
What happens if a solar cell is made of silicon?
These higher energy photons will be absorbed by a silicon solar cell, but the difference in energy between these photons and the silicon band gap is converted into heat (via lattice vibrations — called phonons) rather than into usable electrical energy. The most commonly known solar cell is configured as a large-area p–n junction made from silicon.
