more details, what modules do you have? what is your battery bank voltage and inverter? where are you located geographically (for temperature deration)?

James - this is a proposed system in Western MA. I really want to install PV spring 2007 but have a couple of concerns to address. First, we may not stay in our house due to jobs, so I'm seriously looking to install a system I could reasonably move with me to another house. While my roof pitch/orientation are near perfect for this (MA) location, my roof is extremely high (almost 45'). Since I will be installing much of this myself and I want the possibility of easily relocating, a ground mount system is far more appealing at this time. I have open, unobstructed space on my lot so I can optimize orientation and adjust angle through season easily with ground mount.
I'm looking to install somewhere between 2 and 3 Kw, ground mounted on my lot about 150' from house, so I'm allowing 200' including running wiring through basement to interverter to be located near main panel.
I'm on grid and because of both startup costs and proximity of inverter to gas water heater and furnance in basement, I'm not installing a battery bank at this time (yes, I know there are safe H2 venting solutions). Thus I'm looking for some panels, inteverter, meter/cutoff mains and associated wiring .
I'm open to thoughts/insights.
