I am considering permanently mounting 4 390W panels on top of a 7' x 16' Cargo trailer and 6 additional 390W panels (3 on each side of the trailer) that are deployed using gas-springs. Here is a link to a simulator: https://www.gasspringsshop.com/gas-spring-calculator/
The side mounted panels would be individually deployed with a pair of struts. When closed for travel each panel would be latched at the bottom to prevent accidental opening and probably some type of cover to help prevent damage from road debris. The effort to deploy would be no more than opening the rear hatch of a SUV.
If the trailer is pointed North or South, the side arrays could be deployed progressively and track the sun as the day progresses. Lets say its 10:00 am. The eastern array could be restrained at the optimum angle to prevent full deployment. The western array would be fully deployed at up to +/- 130 degrees from the travel position and retracted as the day progresses. At noon all 10 panels would be flat. At 2:00 pm everything would be reversed with the eastern array fully deployed and the western array partially restrained. At night, when windy, and/or when unattended, the side arrays would be stowed in the travel position.
Each array has its own Victron MPPT 100/50. All panels are wired in parallel.
