If a portion of your solar panels are covered the other panels will still be operating as normal but it will decrease the amount of electricity that the system produces overall.
Do solar panel charge in shade.
Sometimes even if the shade does not completely block the solar panel it can make electricity production stop.
Certain solutions like solar panel design and roof orientation can help prevent an excessive power loss caused due to less sunlight exposure.
A typical solar panel is made of 60 individual solar cells wired together.
So yes solar lights will charge in the shade but nowhere near as well as in sunlight you are better to have some hours of direct sunlight and complete shade than partial shade for the entire day.
All i can say is experiment change the positions and see what happens.
To understand how this works we must dig further into the impact of shadings on solar power production the components of the solar panels and how they work when shades are present.
Though the output will be reduce solar panels will still work in the shade just at less capacity due to lower sunlight exposure.
If they are completely blocked by an object however then the solar panel will stop producing electricity.
Solar panels are composed of individual solar cells and if those cells are covered by shade then they will not work at 100 capacity.
When a solar cell is shaded it loses power.
That loss of power increases electrical resistance within the cell which in turn blocks the flow of electricity coming from upstream solar cells.
Though the numbers will vary depending on how much shade the panels are facing the general rule with clouds and shade is that solar panels will produce about half as much energy as they would with direct sunlight.
