Wall Mounted Solar Panels

Postby GregoInc » Tue Apr 17, 2018 10:01 am

Trying to solve my lack of space for mounting panels, and came across the concept for mount solar panels on walls at a suitable angle. Was wondering if there are people on here that have had exposure to wall mounted panels (see photo) and any negative aspects? Our building is clad in corrugated colorbond, so shouldn't be a problem mounting panels. Any feedback appreciated.

Hi GregoInc :) Welcome :D
I have used that style of thing with a small panel for keeping a battery topped up between camping at my block. I was shocked to come there in winter to a flat battery. :roll: It was to do with the winter sun going south and the building shading the panel completely during the day.
Lesson to learn. Be aware of the sun direction and angle in all seasons. Google the sun angles or ask, for your location. Winter is critical, depending on where you live.
Basically you have to do what you have to do to get your share of the sun. Higher is better too if there is anything around you. How about putting up an awning with panels on it :shock:

i take it your roof has an overhang? 450mm here abouts. it is probably going shade part of your panels in the summer. which means no power at all.

hmm, around these parts the sun moves north in winter...

GregoInc - Wall mounting should be ok, so long as the mounting is sturdy enough and the panels face the right direction and are mostly unshaded. If facing north, be aware that the panels will be in shadow in the morning and afternoon in summer.

Now that is impressive. Did you build it yourself, and what was used for the frame?

The frame is made from 50x50 and 25x25 RHS
The rails slot into the brackets
Each of the panels is bolted to the rails using stainless bolts

The elevation is slightly off optimal for solar production but it is optimal for shading the windows in summer and winter.

As the panels were left over they made the perfect roof for the awning. They have made a big difference in keeping the house cool. I had them up for months before I bothered to connect them
