yesterday, I did the experiment using the aluminum pipe filled up with wax and the result is shown on an excel graph. The first solar intensity measured was found to be w/m^2 at 11:28 am. Then at 11:45, it went up to 1302 w/m^2. The support structure was adjusted at 11:32 am. The intensity went down to 590 w/m^2 at 11:45 am, and again the support structure was adjusted at 11:58m.The intensity was measured again at 12:00 pm 1410 w/m^2 and 1210 w/m^2 at 12:06 pm.The support structure was adjusted at 12:24 pm. I just want to let you guys know must you can find graph on goggle drive as well. Thank you.
