Hi:


look at p .159, no figure attached.


I cut and paste the section below for your review:

On the top of P.159, It said:

"4. An array of rack-mounted PV modules at 45N latitude consists of south-facing rows,
tilted at 30, as shown in the figure. The lowest sun altitude of the year at noon solar time
is 21 as shown in the figure below. "



Please help

Maximum  System Voltage - Method 3- Correction Factor p52 gives no explaination of where the 14 comes from. This is the number of panels in the string. 14 is too many and 13 falls short of the other calulation methods.

The calculation of the Method 1 - percentage method as written did not make sense - the last calulation line = 1 + 0.0962 = 1.1369 should  read = 1 + 0.1369 = 1.1369
