This is a solar panel fixture I designed as a favor for a friend.
The bottom grey block is concrete. The bottom support is inserted into the concrete when puring it, thus joining it quite well. The bottom support is designed so, that it can be used as an insert for the concrete block or as the sopport post itself(to reduce the number of over all parts).
with loosening 1 bolt and removing 1 completely, the post can be broken down, to allow the panel to be parallel with the ground- good for maintenance or of there is a big storm coming.
The panel brackets were made 3mm steel sheet and bent(previously cut with a plasma cutter).
Uses M12 bolts/nuts/washers.
