ᐅ Consultation for photovoltaic system

Hello

we are planning a new semi-detached house.

We want to install a photovoltaic system later on.
We will get the right half shown in the photo. Orientation is southwest.

The photovoltaic system will of course be installed on the southwest side facing the garden.

The black area is the 3x5 m (10x16 ft) terrace, which will later be covered with a fixed terrace roof measuring 4 m (13 ft) deep and 5.5 m (18 ft) wide.

My question is whether it will still be possible to install a photovoltaic system on the roof once the fixed terrace roof is there?

If the terrace roof is on the southwest side in the garden, it will no longer be possible to set up scaffolding.
For maintenance or in case of problems, access to the photovoltaic system will be necessary later on (is access without scaffolding not possible?)

Or can the photovoltaic system be installed without scaffolding?

The house will have a gable roof and 2.5 full stories.

It’s possible, as long as the patio roof does not also cover the main roof of the house. 😉

Only if the installers can access the roof without scaffolding. However, it’s likely to be very difficult without scaffolding. What about the gable side? Can scaffolding be set up there?

We want to retrofit a photovoltaic system later.

Then it’s actually better not to wait until “later,” but to do it “now” while the scaffolding is already in place.

We are only allowed to install the photovoltaic system ourselves after handover :/

The garage is located on the gable side, with only about 1-2m (3-6 feet) of space available.

So, as I suspected, it won’t be possible to install a photovoltaic system if we choose the fixed patio roof, right?

If we install the photovoltaic system in front of the patio roof, it still won’t be accessible for maintenance, repairs, or replacement, which isn’t acceptable.

Of course, it’s possible, if necessary with a ladder and inclined hoist or lift platform. Unfortunately, not all photovoltaic installers do this, and in some cases, it can be more expensive.

Yes

Yes

No, the systems are maintenance-free. Cleaning every few years helps to maintain performance. A ladder and a long pole are sufficient.

By maintenance, I mean things like cleaning, and occasionally a cable might break or a connection might fail. After 20-30 years, a replacement might be necessary. In case of severe hail, a panel could also get damaged.

So, if I understand correctly, we can do both?

However, we should probably install the photovoltaic system before putting up the patio roof, right?

You can also access the roof through skylights on the other side of the roof.
