Description: Array Type: Fixed, Array Tilt: 26.5°. Array Azimuth: 180.0°, DC Rating: 3.3 kW, AC Rating:2.8 kW. The system will add 14 Enphase M215 Microinverters and Suniva MVP240 watt modules.
Added two more rows of panels.
With the power companies premium of $0.12 over the base rate, plus the base rate of $0.085 we should have a zero balance for our electric bill per year.
If not, it's time to unplug a few more things around the house.
BTW for heating last winter we used the same amount of gas/propane, and the addition has more than doubled the sq. footage for the house. Granted it was a warmer winter, but I still don't have insulation in for the ceiling on the second floor. As for air conditioning, it's the same electrical use as before, again for more than twice the space. I must be doing some thing right :-)
