A wall solar panel thing is a way to fix solar panels on building outside walls. It good for jobs where roof space is small or where solar panels need put on up walls. This put-up way let more solar power make without take ground or roof space.
System Components
The wall thing system have three main parts. Wall hold things get fix to wall with big bolts or chemical stuff, they be the base for all the system. Support frames link the hold things to the sun panels, push the panels out to get more sun. Clamps and mount things keep the sun panels on the support frames, make sure each panel sit right and hold tight.
2. Applicable Conditions
Wall fix systems good for building with small roof space and outside walls face south or east that get good sun. Before put up, must check wall can hold weight, like wall stuff, warm cover thick, and old build shape. Only if wall can take solar panels and mount frames weight, then can do install. Also, wall face should have no block things like near builds, trees, or pretty things.
3. Tilt Angle and Orientation
For put on up walls, tilt holders must use to make a certain angle between sun panels and the wall. The tilt angle should pick based on local latitude to get the best sun light angle. In the North half, south walls give the most power; east and west walls can also use, but power making will be less. The direction should choose during design based on the project's real needs.
4. Installation Guidelines
Put these things in mind when you put it up: Fix points must be put right where they go, and the deep of anchor bolts must match what the plan says; after put up, the hold frame must stay flat, and all bolts must be tight to the turn number they say; space between sun panels should be same, and seals must keep water out. Safe steps must also be done when you work up high.
5. Advantages and Limitations
Big good thing is it no take roof or ground space, and sun panels give shade too, make walls less hot in summer. Big bad things include power making not as good as roof ones at best angle, wall way big effect on power out, and more hard to build and fix when work high up.
