Solar Panels on sheds.
I would (with no expertise) be worried about the effect of high winds removing the entire roof of a shed after getting under the solar panels. I think sheds rely on being fairly light and need pinning to the ground to make them secure.
I remember the storms of 1987 and 1989 which caused a lot of damage along the south coast. I knew someone who lived in a very nice house with its own private mooring adjacent to the house. To get the money back, the developer had made them into 3 storey houses. Bigger house, bigger price, but blending in with 2 storey houses better. This resulted in a really low pitch roof with very heavy concrete tiles so they could not lift. In both 1987 and 1989 a lot of tiles from this development were flying around causing huge damage to parked cars. Luckily in 1987 it was overnight, so nobody injured. After 1989, insurance premiums for the owners went through the roof (pun intended). All the blame was directed to the manufacturers by the architect and structural engineers. There was also damage to all kinds of rooves not in good condition, myself included. The only ones untouched were the fake slate type that are very light and all clipped down.
