Our 5Kwh Solar PV System
The system was placed in service (connected to Austin Energy grid) on June 5, 2008. See below for a spreadsheet showing usage.
The main system components are:
- 30
Evergreen Spruce
180 watt PV solar panels producing up to 5.4 kilowatts of DC power for the inverter.
The solar panels are oriented SSW (210 degrees).
- One SMA
Sunny Boy 5000 Inverter producing up to 5.2 kilowatts (95.5% efficiency) of AC power for onsite consumption and/or
transmission to the Austin Energy grid.- (L to R) Net Energy Meter, Service Panel, Solar Energy Meter, AC Disconnect, Inverter, DC Disconnect.
- Solar Energy Meter showing kilowatt hours (kWh) of AC energy generated by solar panels and inverter.
- Net Energy Meter showing RE ("Returned Energy" -- kWh returned to the grid).
The display rotates through DE (Delivered Energy -- from grid), RE (Returned Energy -- to grid), and NE
(Net Energy used). The underbars below the 5-digit counter move left-to-right when power is being drawn
from the grid and right-to-left when power is being returned to the grid.
(Note: these meters were replaced by similar ones on April 30, 2010.)
