[TRNSYS-users] SDHW example TRNSYS

In this attachment file, I tried to calculate hourly thermal efficiency of solar collector by using this two equation  and . But after comparing the result, why the hourly efficiency different?

And also please check "Comparison Energy balance" sheet. I don't understand why q gain from solar collector has different value with qin storage. even though in the example there is no heat exchanger between solar collector and storage.

Thank you.
