ᐅ Is it practical to install a photovoltaic system on the west or east side of a building?

Hello,
we are wondering whether we should install a photovoltaic system on the roof in the near future. The empty conduits for it are already in place. However, we have a hipped roof. On the south side, there is just over 20m² (215 sq ft) available for the system. Would it make sense to also use the west (or east) side to increase the area, even if the sun doesn’t hit it at the optimal angle?

Oh dear, I signed up here. I have to admit that the overwhelming amount of information is completely confusing me.
I will look for our plans with the roof dimensions, etc., and then carefully start asking my beginner questions.
We also have a garage with a gable roof and an east-facing orientation. The house is located to the west.

Clear the memory and set all the areas. If you’re diligent, you can already start working on the layout. That would be a good place to start. Yes, I can definitely figure out the areas, but I have no idea how big a module is, whether they are all the same size or each different, if there need to be gaps, and so on. I’m really starting from zero. ops:

There are also other module sizes available if needed.

While you don’t get the maximum energy output per square meter, without a storage system you have more hours of self-consumption than with a south-facing system. It’s not that complicated. Your roof is as it is. When it comes to panels, electronics, storage, and so on, you will encounter “doctrinal disputes.”

Is it worth researching the "best" or most efficient ones online at the time of installation and asking the installer to order and install those? Or is it better to simply go with the panels recommended by the contractor, since the differences are usually minimal?
