Configuring hot water solar panels
I currently have 3 solar water panels connected in series to provide heating to my underfloor heating in the house.
As I write (a nice sunny Sunday at 13h) the water temperature in the floor is 32C and the exit temperature of the panels is 54C. I have a coil heat exchanger in a 100L water tank to transfer heat.
I have now obtained a 4th panel that I will add to the system.
The question is; do I connect the 4th panel in series with the 3 existing panels or do I split the panels into 2 banks of 2 panels.
Any thoughts? Is one configuration better than the other?
