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

[Leepaul]

Dear, all 
My question is: if I have a weather file of a city ,city's logitude difference is shown as -28.9, then do I have to modify it and make it between  -15 and 15 degree?if I don't modify it, then I will get a wrong simulation result? thank you for your time.regard, paul> From: jon at esru.strath.ac.uk> To: esprfans at hotmail.com; esp-r at lists.strath.ac.uk> Date: Tue, 30 Dec 2008 09:53:09 +0000> Subject: RE: [esp-r] effect of longitude and latitude on the PV window power output?> > > 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.> > -Jon Hand> ________________________________________> From: esp-r-bounces at lists.strath.ac.uk [esp-r-bounces at lists.strath.ac.uk] On Behalf Of Leepaul [esprfans at hotmail.com]> Sent: 27 December 2008 02:06> To: esp-r at lists.strath.ac.uk> Subject: [esp-r] effect of longitude and latitude on the PV window power output?> > 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> > ________________________________> MSN保护盾，十八般武艺保障MSN安全！ 现在就下载！<http://im.live.cn/safe/>
