Saw picture or perhaps a YT video of an arch on yacht that had solar panels
slide out like a dining room table when conditions allowed. However, when you really want those panels
is when its windy, cloudy and wet not flat calm and sunny.
We replaced a suitcase solar
panel that slipped and smashed with one of these. Quality isn't great but its light and easy to store away. More importantly if you move it several times a day to face the sun it really earns its keep and generates quite a bit of power compared to panels
in a fixed position.
