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.
