Custom: Roof Solar Structure
Disclaimer: Just sharing a DIY engineering project my dad and I recently finished to get feedback and show off the setup.
---------------
We built this entirely from scratch by hand. My dad and I designed and fabricated the mounting frame ourselves because hiring contractors was way out of our budget, and modular frames like this aren't really available off the shelf locally anyway.
-----------------------------
While the frame might look lightweight, it relies on classic bridge-building principles. We went with a triangular truss layout to distribute the weight evenly, maximize rigidity, and keep everything rock-solid against strong wind loads in Karachi.
-----------------------------------------
The best part is that it's 100% modular and relocatable. The entire structure is bolted together, with the legs anchored into small, localized concrete footings. Whenever we move, we can just break the small concrete pads, unbolt the frame, and take the whole setup with us without damaging the roof or the frame.
