Dear community,
I am currently exploring the use of a photovoltaic system for our upcoming new-build project. Most likely, it will be the classic combination of an air-source heat pump and a photovoltaic system (including storage).
In a book, I came across some very interesting application scenarios and wondered whether the control systems of photovoltaic installations are really that smart.
The following application scenarios (when using an energy storage system) would be ideal for our house:
- Combination of heat pump and photovoltaic
- Pool heating
- Electric vehicle wallbox
Example of a control logic: charge the car at night only if stored energy is available; heat the pool only during the day with pure solar energy; and so on.
What is the reality like? How would you implement such logics?
Thanks!

Here I return to my point about holism. For me, these are implementations that clearly exceed my skills and also my level of interest. To do it properly, I would have to spend a very long time studying each individual technology. That’s why I really find it unfortunate that in a typical construction project there probably isn’t a service provider who brings all these loose ends together. Difficult. I think you are overestimating what’s possible. Assuming your photovoltaic system is large enough, it automatically means you have enough power between 9 a.m. and 7 p.m. You simply schedule the major consumers during this time, and your home automation is basically done. Common charging stations (wallboxes) do the automatic charging as well. Check. Then you just need the heat pump, which is straightforward too. You only heat water around midday. That’s sufficient. During transitional seasons, you only heat during the day. In the core of winter, you raise the temperature by 2°C (4°F) between 10 a.m. and 4 p.m. All of this takes about 10 minutes to set up in the heating system’s settings tab. And all the extra optimization you could do with a lot of effort might increase your self-generated electricity use by maybe 10%.
