Carl, you may also be interested in HOMER-- free 2-week trial available
of the latest version (after that, $99 per 6-month renewal, despite zero
updates since Nov 2010). There's also the free "legacy" version that's a
few years old.

Hello Wrenches,
I am in need of an analysis for a large battery backup system. I am
looking for a sweet spot in PV array size and battery bank size. I need
this modeled on a time of day basis, and evaluated monthly thru a full
calendar year. I am told that PVSYST can perform such an analysis but I
neither have the tool nor the experience using it to perform the
modeling, so I am looking to hire the job out to someone who does. If
any of you have the software and expertise to use it please contact me
off list for more detailed requirements.
With Regards
Carl Adams, SunRock Solar.
