Other components let users to enter the test flow rate for a specific collector but I was surprised since this Type doesn’t include this variable. Why is this? How to select the best flow rate since the one reported on the test standard report is much higher than the one the manufacturer recommends? <o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US>The second question is about the correct manner to configure a solar array of X numbers of collector in series times Y numbers of collector in parallel. Do I have to use a calculator in order to construct such configuration or is there another way by using Type1288 only?<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US>The third one is about IAM for diffuse radiation. I tried to set a value of 1.015 (according to a certified report) but Trnsys got stuck and I had to use Ctrl+Alt+Del in order to end the task. So I used a value of 1 and calculations were performed without any problem. Do you know the reason for this problem? <o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US>And the last question. What is the best way to calculate the efficiency of collectors using the EN-12975 standard?
