Hi guys, I'm very confused related to the PV energy production. I don't understand where is the truth.
I need for example to use Daily PV Energy Budget � 1313Wh/day from a solar energy system, at 12 V/220V. (Only a TV set + lights) - Bright Sunshine � 6 Hours - 3 days of autonomy Based on my calculation the results are: - Total Rated Battery Capacity calculated 729 Ah - Using batteries at 6V/450Ah I need 4 batteries connected in series/parallel And if I'm using Siemens PV � SP110 with the following characteristics, 110W - 6.47A/17V Based on this then I need 3 modules on parallel. Am I right? But�here is the confusion that I have. Those panels produce according with Siemens specs at 6 h bright sunshine � 6x110W = 660W per day !�. but my system works with 12 V not 17 V!! �. So the results should be 6h x6.47A x12V = 465W ! � well my question is : Where are 200W?� because as far as I understand the max current generated will be 6.47Amps .. and not more? I hope you guys can help me ! Thanks, Florin ------------------------ Yahoo! Groups Sponsor ---------------------~--> Yahoo!
