PV Graph Explanation

8 Sun 130 panels on sun-tracking frame

My PV system consists of the following:

  • 16 Sun Electronics 130W panels (made with SunPower cells)
  • 8 Siemens SM55 panels (55 Watts each)
  • Xantrex XW-6048 inverter
  • Xantrex MPPT-60 Solar charge controller
  • Xantrex SCP II controllers
  • Xantrex Communications Gateway

    Eight of the Sun 130W panels are mounted on an aluminum frame that moves to track the sun (picture above). The other eight are fixed to the roof (not shown). The eight SM55s are also fixed, but I will likely replace them in time so they are not permanently mounted. Here is a picture of all the panels (plus four more SM55s) before they were mounted.
