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.

@Hausbau 55: Great, looks good. Nothing stands in the way of your own DIY attic now!
Thanks, but I still have a lot of reading and learning to do. It would be great if I could use the battery from the campervan for the house. The battery must stay permanently in the campervan because we like to set off spontaneously.
Do you have any initial tips for me?

Um, I haven’t done much research yet. Right now, I’m under so much stress that although I’m really excited about all this stuff, I simply don’t have time to fully focus on it. Buying a ready-made system is not an option, as it doesn’t make financial sense for me. I’ll wait to see what’s left after taxes, then I’ll put panels on the roof. Then step by step …

Your system is already quite large, so a bigger battery storage would definitely make sense.

At the current electricity price, a storage system can cost about €300/kW (approximately $320/kW) if it is to be operated economically—at least for an average household. With a self-built system, you can even afford to spend a bit more since you’re able to replace individual components yourself in case of defects. Commercial systems usually can’t handle that, which often leads to major problems.

I know I often sound like I’m against storage systems. But in reality, I’m really looking forward to having one myself… Still, I try to hold back until I’m sure it will be cost-effective.

I bought my 8 cells and the 2 BMS directly from the Chinese manufacturer in spring 21. I believe it was less than 1000 euros including accessories.

How much is that in €/kWh?

Understandable—if the heat pump isn’t cost-effective yet, then at least the storage tank should make the most of it … 😀

A storage tank will only be cost-effective if you install it yourself.
