Hi Ron ~
'It takes four minutes or more just to change pages the last few days. I hope this isn't the new software.'
It's not. We're seriously considering/looking into moving to SMF (simple machines forum) in the near future. For some reason - we had things up and moving at an almost reasonable speed a month ago here, but it seems to be slowing down again doesn't it...
'I'd like to see the math test go away, and why if I go to the wind page should I have to select wind again from the little pulldown menu. Doesn't the soft know what page it just loaded at the speed of molasses.'
Yes, it seems better some times than others but it's been bad lately.
' I know this isn't the fault of the site owners I just hope the new situation will help with this stuff. '
So do I! We're working on it... hopefully slightly faster than slow as molasses but probably only slightly ;-)
'Can anyone recomend the best book to explain the calcs necessary and the various wiring diagrams needed to keep a pv system running happily. I learned all this stuff 20 years ago but need to get up to speed again with a good refresher. Thank you all for being here answering all these questions.'
The SEI book, 'Photovoltaics: Design and Installation Manual' is probably the best thing I know of out there. It's here on Amazon:
