ᐅ Solar Power System: Yes or No?

@Brombadegs:

A solar thermal system is used for hot water – either with or without heating support.
If you want to generate electricity, you need a photovoltaic system.

For the reasons you mentioned, I also don’t see much sense in a solar thermal system, since the sun is usually present when hot water demand is low or almost nonexistent.

Hi,

thanks – I’m much clearer now. Do you have any idea how much a system like that might cost for our electricity needs?

Thanks, Brombadegs

Although I am still at the beginning of my planning, I have already found a few nice ideas.

The new house would stand free and would always have sun. No trees would be in the way. But it will probably have a gable roof. Which direction should the roof surface face then? East? Directly south? I can still plan all of this...

Towards the midday sun, meaning towards the south. Depending on the longitude, a different roof pitch is required. I read somewhere about approximately 30° pitch. However, this depends on the location. Minor deviations are not a big problem. With a southeast or southwest orientation, about 90% efficiency can still be achieved.

That’s what I know so far. I have not verified it yet. First, I need to plan and finance the right house.

Hi,
Oh, I see... Well, I’m in too. Let’s see who finishes first *smile*

No one here will be able to answer that question for you. It’s like asking about the optimal exterior wall.

I completely agree. The whole system has to work together! A solar system makes sense if the other components are coordinated with it or already in place. This includes excellent insulation to minimize heat loss. The builder would install a 300-liter (79-gallon) storage tank, which is definitely sufficient. Even with four people living in the house, this volume easily covers everyone’s showering needs.

However, you should be aware that this kind of system typically pays for itself only after about 10 years. Only then will you really start saving money. The better solution is, of course, to install everything right away (pipes, wiring, etc.) so you don’t end up with dirt or mess inside the house later on.

Yes, I would recommend everyone to install a solar system if it is financially feasible.

Best regards

The better approach would probably be to use the investment in the solar thermal system to permanently reduce the demand (additional insulation).

For economic reasons, I see this quite differently.

Best regards.
