I designed solar thermal collector (Flat plate) for a DHW system in a building

I put only one Thermal Collector as a tryout and i want to ask this

The heat in GJ is the heat that is produced by the solar thermal collector, but what does this 100% percent heat refers to?

What does 100% mean in this table? please see the attached photo

Thank you

This is the % of the on-site thermal sources. So for each row i it's that row's Heat GJ / Total On-site Thermal Sources GJ.

$$Percentage = 100 \times \frac{HeatGJ_{i}}{\sum_{j=1}^{6}HeatGJ_{j}}$$

You can see the source code here in

So logically in your case, since you have only one type of on-site thermal sources, it shows 100%.

True because there is only solar thermal source that is why it says 100%, you are right Thank you very much this is really helpful
