April 2010 Back to March 2010 Forward to May 2010 We are running house demand from the protected distribution panel. Net meter is checked in the mornings just before the sun comes up. Grid feed is checked from the daily log of Sunny Portal the next morning at 06:15 and put into the previous day's log, that way 100% of the turbine generation through 24:00 is included. 4/1 Net meter 000645. Grid feed 45.84 KWh, fixed array 16.32, trackers 22.83, turbine 6.69. 4/2 Net meter 000618. Grid feed 38.29 KWh, fixed array 12.21, trackers 15.66, turbine 10.41. Turned off the turbine due to lightning storm in area at 20:00. The turbine seems to have a new problem, it furls at medium wind speeds. It begins furling at 2000 watts generation and will not generate above 2400 watts, a full 1000 watts less than new. 4/3 Net meter 000596. Turned on turbine at 04:22. Grid feed 38.48 KWh, fixed array 15.54, trackers 19.14, turbine 3.90. 4/4 Net meter 000574. Grid feed 44.61 KWh, fixed array 15.63, trackers 20.78, turbine 8.20. 4/5 Net meter 000541. Grid feed 34.51 KWh, fixed array 12.66, trackers 15.93, turbine 5.92 4/6 Net meter 000522. Grid feed 48.28 KWh, fixed array 14.60, trackers 20.16, turbine 13.52. 4/7 Net meter 000490. Grid feed 25.56 KWh, fixed array 6.91, trackers 8.17, turbine 10.48. 4/8 Net meter 000474. Grid feed 54.44 KWh, fixed array 16.97, trackers 22.75, turbine 14.72. I needed to clean pollen off the collectors this morning. It was really thick. 4/9 Net meter 000443. Grid feed 40.78 KWh, fixed array 16.57, trackers 23.71, turbine 0.50. 4/10 Net meter 000420. Grid feed 41.27 KWh, fixed array 16.64, trackers 23.43, turbine 1.20. 4/11 Net meter 000396. Grid feed 38.88 KWh, fixed array 16, trackers 22.68, turbine 0.20. 4/12 Net meter 000373. Grid feed 40.80 KWh, fixed array 16.32, trackers 23.08, turbine 1.40. 4/13 Net meter 000348. Grid feed 39.71 KWh, fixed array 15.94, trackers 22.86, turbine 0.91. 4/14 Net meter 000326. Grid feed 42.15 KWh, fixed array 15.98, trackers 22.98, turbine 3.19. 4/15 Net meter 000304. Grid feed 31.17 KWh, fixed array 11.82, trackers 17.35, turbine 2.0. 4/16 Net meter 000284. Grid feed 33.27 KWh, fixed array 11.11, trackers 16.65, turbine 5.51. 4/17 Net meter 000277. Grid feed 40 KWh, fixed array 15.90, trackers 22.21, turbine 1.89. 4/18 Net meter 000259. Grid feed 37.01 KWh, fixed array 15.05, trackers 20.26, turbine 1.70. 4/19 Net meter 000236. Grid feed 24.26 KWh, fixed array 10.63, trackers 12.38, turbine 1.25. 4/20 Net meter 000234. Grid feed 39.55 KWh, fixed array 15.85, trackers 23.10, turbine 0.60. 4/21 Net meter 000219. Grid feed 26.54 KWh, fixed array 10.62, trackers 15.82, turbine 0.10. 4/22 Net meter 000211. Grid feed 14.18 KWh, fixed array 5.80, trackers 8.38, turbine 0.0. 4/23 Net meter 000211. Grid feed 23.84 KWh, fixed array 7.57, trackers 8.78, turbine 7.49. *4/24 Net meter 000205. Grid power failed at 15:45. System switch test performed and perfect. "FOR THE RECORD" No voltage on grid feed. House on Protected circuit never lost power. I noticed almost immediately when the battery bank voltage changed from preset grid feed value. Otherwise we never would have known grid lost power during last storm that went through. At 16:20, the battery bank is bouncing on full, 5556.5 volts, with turbine generation and array 3. Array 1 and 2 are facing East as we had clouds all day till now. COOL!! My new continuous system monitor got finished just in time. Grid returned at 17:15. Grid feed 18.40 KWh, PV generation 6.71, turbine 11.69. 4/25 Net meter 000210. Grid feed 24.69 KWh, fixed array 2.64, trackers 2.64, turbine 19.41. 4/26 Net meter 000205. Grid feed 23.45, fixed array 3.43, trackers 3.11, turbine 16.91. Below is the data log from Sunny Portal. The red bar is PV+wind and the blue bar is generation from our Whisper 500 3 KW turbine. It's been very windy. I'd call this turbine, in reality, a 1 KW turbine, although at times it was generating 2.8 during gusts. The data speaks for it's self. I am thankful for it's production during these cloudy days. This graph indicates maximum average generation during winds high and gusty enough to have repeated turbine furling. 4/27 Net meter 000207. Grid feed 31.39, fixed array 9.33, trackers 13.16, turbine 8.9. 4/28 Net meter 000204. Grid feed 35.64 KWh, fixed array 13.59, trackers 20.37,turbine 1.68. 4/29 Net meter 000181. Grid feed 52.48, fixed array 16.00, trackers 23.88, turbine 12.60. 4/30 Net meter 000147. Grid feed 10.75, fixed array 1.15, trackers 1.22, turbine 8.38. Turned off the turbine, and isolated the controller, at 20:00 due to major electrical storm arriving. April 2010 Back to March 2010 Forward to May 2010
