Our 1.52kW Photo Voltaic Array is made up of eight 190W monocrystaline panels (Ulica Part No: UL-190D-84, provided by Soanar SSPM190ECO-UL) facing 13°East on 22° roof pitch, mounted above the Solarhart Black Chrome 12 gas boosted hot water heater.
The Inverter is a Xantrex GT2.8-AU-QC-230 expandable up to a maximum output of 3kW, which I monitor and data log with my computer using the Solar Guppy SGT program.
My systems is running Windows 7 Ultimate 64bit running an XP virtual machine (required for 32 bit drivers that the SGT program talks to) that talks to a Jaycar XC4134 Ethernet (TCP/IP) to Serial converter connected to the Xantrex Inverter.
Current output and progressive power output totals (updated every 15 minutes during the day as long as my computer is still running).
A typical full sun Canberra Winters day production. This particular day, 22 Jul 2010, peaked at 1135W and produced 7434Whrs for the day. This day the panels had full sunlight and produced electricity from 7:39:49 AM after sunrise at 7:06AM EST to 5:00:48 PM before sunset at 5:14PM EST. It's interesting to see the production as the sun traverses the sky, if the panels could track the sun and position themselves at the most direct face to the sun then the picture would look significantly different. The sun appears to be at its most direct full sun position over the panels about 11:50AM each day.
