ᐅ Solar Power System: Yes or No?

...Certainly, €uro must have a detailed and factual explanation for such a qualified statement.

Unfortunately, I don't have time for that. Maybe consulting a common physics textbook or wiki will help. During my studies, temperature was measured in °C and energy in kWh! It’s unlikely that this has changed since then. In the end, everyone gets what they really deserve.

Kind regards

Hello €uro

During your studies, you should have also learned about the conservation of energy.
Energy cannot be "produced" or "consumed," it can only be converted from one form to another – does that ring a bell?

And what do you do every day with your electric kettle or coffee maker?

Exactly – you convert energy in the form of electric current into heat!
What unit is electric current measured in?
And what does it do?
Exactly!
It raises the water temperature by several degrees Celsius (°C).

Is the electric current consumed in the process?
What color is electric current?

Hello,

That's correct!

Energy is converted into heat energy, not into temperature. Therefore, temperature is not the same as energy, nor is it the same as thermal energy. Temperature simply describes the state.

So, I find it somewhat bold to equate temperature directly with energy...

Hello
Solar thermal system:
- The orientation and tilt should be similar to photovoltaic panels – perhaps the optimal orientation is a bit more towards the west, since I want to capture heat that lasts longer in the day...

- Regarding cost-effectiveness: How long does the temperature remain stable in the hot water tanks? Given how well insulated they are nowadays, I would guess around 12-14 hours. This means in summer, I can still shower or bathe the whole family in the evening using water heated by the solar thermal system.
And even by the next morning, there should still be warm water left for showers.
In winter (assuming good weather, of course), the hot water tank should still be warm enough to cover my evening needs.
Also, I plan to connect my dishwasher and washing machine to the hot water supply. It would be wasteful to keep heating the water electrically or with geothermal energy, while the hot water tank cools down unused...

Personally, everyone I know with a solar thermal system has only said good things. None of them are dissatisfied...

That’s my two cents.

In winter, the system won’t be much help for hot water or heating. It’s a nice bonus, but the benefits are mostly noticeable in summer and the transitional seasons. November, December, and January... you won’t get much out of a solar thermal system alone during those months.

I have some charts about orientation and tilt angles — let me see if I can upload them, they’re quite interesting.
