Affordable solar system - experiences

Hey

I am considering having a solar system installed on my house and hope for your help and good advice.
I have already informed myself about the solar system. I also have a few questions.
What do you think? What is a reasonable price for a 12 square meter solar system? Sorry for the stupid questions, I am an absolute beginner when it comes to solar systems.

Best regards

Hello,

...I am considering having a solar system installed on my house and hope for your help and good advice.

Is it a new building or an existing one? Solar thermal system or photovoltaic? Best regards.

Solar thermal system or photovoltaics?

I would guess solar thermal. 12m² for photovoltaics is quite small. For solar thermal, it would still need to be clarified whether it is only for hot water or also for heating support. In that case, I would again guess heating support with 12m².

Probably! Systems with actually usable yields are usually not exactly "cost-effective";) Regards

Yes, but it doesn't necessarily have to be a super expensive system. What is important is that the technology is mature. For heating support, I would only use tube collectors anyway. However, none with heat pipe technology. Mine cost just under €9000, including self-installation. My uncle has a Paradigma and already paid €3000 for the installation. That doesn't have to be the case.

What matters in my opinion is that the yield (kWh/a) is proportional to the investment. Standard systems are miles away from this! I have measured systems where the yield was only slightly higher than the electricity consumption for control and pump. A fitting investment, financed with interest and repayment. In solar thermal systems, the thermal storage of energy in relation to user behavior (energy consumption) is the problem! Regards
