[TRNSYS-users] Effect of Collector Slope on Collector Gain

David,

Since I am unable to capture the effect of slope variation on the
useful energy, I'm guessing that my connections between component
Type15 and Type1b are not accurate. I'm attaching an image of the
connections made, could you please point out my mistake here?

Thanks a lot.
Dev
