Re: [RE-wrenches] large array string sizing

Jeff: Another thought occurred: it is possible, if you are using a web based sizing tool, that the tool is incorrect. You may want to run the numbers yourself to verify. If I can look over some part of this for you off-line, I would be willing to help if I can. William Miller

[RE-wrenches] Array seperation

It seem's like I remember a program that would give you the physical seperation between 2 array's? So that the first array doesn't shade the second. I know it is fairly basic math but if there was a program or website it would be faster onsite. Sent from my BlackBerry® wireless device from U.S.

Hi Jeff, Is there no way to select a different inverter or panel? without knowing which you are using its hard to help here. But the issue with being right at the low end of voltage isn't good for the long term production of the system, jay peltz power ___

[RE-wrenches] PV arrays and comp. shingle lifespan

Any experiential observations out there that would point towards a PV array extending the lifespan of a composite shingle roof? Shortening it for some reason? Seems that most composite shingles are warranted for a shorter time period than the PV modules. Phil Schneider Creative Energies

I'm sure Bill's tool works well, but if anyone wants a ballpark number. At 35 degrees north latitude, and if you want no obstruction from 9:00 am to 3:00 pm on December 21st (winter solstice), and your rows are E-W, then space the rows 2.1X the difference between the top of the PV module to the bot

Re: [RE-wrenches] Array seperation

I'm a fan of Goggle SketchUp. The free version seems to cover most applications. If you want to drop it into CAD though you'll need the full version. There is a learning curve associated with the program but once you get through that, it is great since you can orient the arrays/building at whatever

[RE-wrenches] Voltage correction (was: large array string sizing)

This brings up some interesting questions I had yesterday on this subject. 1. If the percentage change for Vmp is greater than Voc but the manufacturer only lists the temperature coefficient for Voc, what would be considered the best practice to calculate the Vmp loss? Use the temperature coeff
