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.

In summer, even such a small system probably generates more than 50 kWh on sunny days. Unless the electric car is completely drained and ready, I would be surprised if all that energy could be consumed on-site. That’s exactly what the battery storage is for—to capture the surplus. And if necessary, you can be more generous with your consumption (air conditioning, outdoor lighting, pool heating, etc.).
The main problem with photovoltaic systems is the terrible bureaucracy. I have little hope that this will improve anytime soon (that would be too easy). Even a small balcony system needs to be registered, which is ridiculous. In the Netherlands, you can just mount the panels on the roof, and if there’s surplus energy, the electricity meter runs backward—that’s how it should be.

Could you suggest some promising *g* keywords for DIY storage?
Thanks!Try searching on YouTube for "drbacke" or "DIY power storage," "DIY LiFePO4 power storage." You’ll find some people who have built their storage systems for a fraction of the usual cost. The doctor also has a forum on batteries.DIY energy storage is very challenging. I do almost everything myself, but even I wouldn’t attempt this. First of all, it’s difficult to properly integrate compatible inverters and battery management systems. The number of cells, cell voltage, and other factors need to match.
There are some people who do this, but in the end, it usually comes down to the same financial cost.
With 48 V LiFePO4 batteries from China, you can only manage single-phase systems up to 5 kW at best. Anything beyond that requires high voltage. And should you do DIY? No!

Hausbau 5515 Jan 2022 15:27Last year, I built a battery pack myself using 2 x 200 Ah 12.8V cells sourced from China. I did a lot of research beforehand. Out of the 400 Ah total capacity, you can discharge about 80 to 90%, so you can use approximately 320 to 360 Ah. Previously, I had 2 lead-acid batteries from Büttner, each with 120 Ah. With lead-acid batteries, you can only use about 50% of the 240 Ah total capacity. Switching to LiFePO4 was very beneficial for off-grid living in the motorhome. The motorhome has a 2000W inverter from Solartronics... theoretically, you can run it at 2 kW load for 2 hours.
Our bungalow is almost ready for handover, and the 13.68 kWp (kilowatt peak) photovoltaic system is already operational. Now I am considering whether the motorhome’s battery could also be used in the house.

“Single-phase”? You’re mixing things up. Multi-phase comes from the inverter if that’s what you want.
@Hausbau 55: Great, looks good. Nothing stands in the way of your own DIY battery system!
