I am fairly new to archism, and I am using it for calculating the annual electrical energy produced by PV panels. I am testing two parameters: the tilted degree of the PV panels, and the distance between them. Surprisingly, one of the value from the analysis does not make sense/incorrect as highlighted in the attached (pdf) table. The results of the the angle 22 tilted are strange. I tried to increase the degree by a small value (1 degree) and the result was very huge, therefore the changes in the next tilted angle cases may got effected !!
