different inclination of solar collectors

Hello,

I want to install a solar system for hot water and heating support at our house. 6 flat plate collectors are to be installed on the roof. Now the following problem arises:

We have a house with a 30° roof pitch. However, because of roof windows and existing photovoltaics, there is only space for 3 collectors. The other 3 are to be installed on the roof of an extension; roof pitch here is 50°. The distance from one row of collectors to the other would be about 3 meters. Raising the collectors on the 30° main roof is not an option due to shading of the existing photovoltaics.

How does the different installation angle affect the system, or is it even possible to realize it this way? Or do all collectors have to/should have the same inclination? A friend told me it would be unfavorable to install collectors with different inclinations. He had read it somewhere but could not tell me why that should be.

Does anyone have any idea?

Thanks in advance.

As it looks, there are only people as clueless as me here. :-((

Hello,

...I want to install a solar system for hot water and heating support at our house.

I would think about that once again ;)

...An acquaintance told me it would be unfavorable to set up the collectors at different angles.

The exact opposite can also happen. ;)

Best regards

AHA - well, those are some informations :confused:

What was expected? Exact planning service for free? solar thermal systems, like any heat pump or heating system, must be precisely planned/dimensioned, otherwise the investment will probably fail (money pit). Certainly, a few kWh can be harvested, but economically, this is certainly not the case for a single-family house! If there is still available space, it would certainly be more sensible to expand photovoltaic. Best regards

Solar system for heating support is uneconomical if you cannot operate the underfloor heating with low temperature. Everything related to heating support and radiators is uneconomical. Therefore, it would only make sense to use solar for domestic hot water.
