I wanted to park my bikes - or depending on the Season - my Renault Twizy somewhat protected and easy accessible.
After adjusting the yard fence to form a pocket I put a frame aluminium profiles on top. On top of that is a second frame which is angled at 10 degrees and on that are the solar panels.
10 degrees seem to be a viable compromise between self cleaning, sun capture, construction height and openings to the elements on the side.
It was much more challenging than i thought to find solar modules with a form factor fitting the shed.
4 Standard modules where far to big. So I choose two modern 410 Wp modules and 3 130 Wp “camping” modules.
I got two 600 W dyne (“Bosswerk”) Micro-inverters cheap, because everybody want’s 800 W now and they have a regulatory issue with a missing relay.
The 130 kWp panels are cabled serially but still seem to have issues getting enough voltage to start the inverter in the morning.
I’m happy with the project. Things in the shed are getting much less wet during rain und not baking hot during sunshine.
I might close the gaps between the panels obe day but that is low priority- the thing was never meant to be totally watertight.
I also like it being some kind of Solarpunk landmark in our street.
Very nice! Though it looks like your micro inverters are mounted right where water would be coming through, looks like they would be easy to relocate though. It is possible to use a combination of t-molding on the top along with caulk between the panels to reduce water penetration cheaply and easily, while not being 100% water tight it gets pretty close.
