[esp-r] Re: effect of longitude and latitude on the PV window power output?

[Jon Hand]

Changes in longitude will result in the angle of the sun
which will alter the geometric relationship between the sun
and a surface.

It should be easy to test this running a simulation and dumping
the PV performance to a file and then altering the MODEL SITE position and making
a second run and looking at the differences.

Dear all,

what is the effect of longitude and latitude on power output of the vertical PV windows toward the west.

for example, I'm simulating the vertical PV window toward the west located at London, fisrtly I get a power output from the original weather file, then keep anything of London weather file unchanged but change London' longitude, then what will happen for power output?

regards,
paul
