PV OUTPUT DATA

February 2009  Back to January 09  Forward to March 09

February stats; Turbine production 152.57 KWh. PV production 277.89 KWh. 99% powered by RE.

2/1 I am reassembling the turbine tower mast 30 feet taller, 96 feet from ground to rotor shaft. Apparently all the problems with the solar hydronics were caused by a faulty tank temp sensor. I have replace it and now it seems to operate properly. PV production 14.75 KWh. The lengthened turbine mast is in the air on the dry run, without the turbine. Solarhydronic working well and up to 41C.

2/2 5:10, It seems the battery soc discrepancy still troubles the system. It currently shows 60% and the power and voltage suggests much more. I think it is  20% off. I will need to reboot the system new battery the next time I switch to grid. Finished the turbine. PV production 12.38 KWh. Turbine production 0.98 KWh. Solarhydronic at 43C.

2/3 5:56, Got the turbine up just in time. Great generation this morning. It took a total of four days for me to rebuild the turbine mast solo, about a thousand feet of new guy wire, new conduit, and now sixteen guys to hold 96 feet, about 120 cable clamps, including the lightning protection and anti twist. About a hundred feet seems to be the limit of 5" SCD 40 pipe. One thing is clear after a year of operation: I don't need more generation, only grid tie to fully realize my generation potential!!!!!!. If the class action suit against Missouri utilities doesn't fruit soon, I will expose myself to a $1,000,000.00 liability to fully realize this potential. You can't get blood from a beet anyway. In a little while, when the sun rises, I will have 5 KW generation that will governor it's self to nearly zero when the battery bank is full by ten thirty. What a waste!! PV production 21.73 KWh. Turbine production  14.31 KWh. 36 KWh total today! Used two load shed electric/fluid space heaters, 1.4 KW and 900/1.4 KW, and the hot water heater at 3.6 KW. The wind turbine still REG'ed off some today.

2/4 I had to switch to grid to heat water early morning and recommissioned the battery bank new to start battery soc over. The system is better with the new shunt but it still accumulated discrepancy in the soc of nearly 20% in a month period. PV production 13.32 KWh. Turbine production 5.23 KWh.

2/5 7:13, The wind is absolutely still at the house and we have periods of 600 watt generation with the turbine, and the wind is from the South! PV production 17.47 KWh. Turbine production 1.69 KWh and just starting to spin up with a South wind tonight. Water at 51C.

2/6 PV production 14.2 KWh. Turbine production 1.72 KWh. Hot water 52C.

 2/7 PV production 3.5 KWh. Turbine production 2.15 KWh. No hot water today. Switched to grid at 16:20

2/8 Switched to RE at 8:20. PV production 7.6 KWh. Turbine production 0.11 KWh.

2/9 PV production 5.13 KWh. Turbine production 6.84 KWh.

2/10 PV production 3.68 KWh. Turbine production 5.76 KWh.

2/11 PV production 0.64 KWh. Turbine production 9.66 KWh. Turbine generation keeps us off grid the past three days.

2/12 PV production 15.23 KWh. Turbine production 1.7 KWh.

2/13 Woke up to a full battery and high winds that are not on TWC, which says 8 mph. There is no breeze at the house and the turbine is generating around 2,000 watts, +- 500. PV production 4.46 KWh. Turbine production 12.13 KWh.

2/14 5:33, again, turbine generation in early morning that bumped full the battery soc and as soon as my coffee is brewed I will turn on the electric water heater to run on winter wind. PV production 4.84 KWh. Turbine production 9.22 KWh. The turbine is still the key to staying energized. This is definitely an improvement. The turbine has generated as much power in 14 days, since elevating to 96 feet, as all last summer.

2/15 I wonder if it is coincidence that the turbine is performing so much better lately, or that it is on a higher tower? There is no doubt I have gained several days of independent power generation with the taller turbine. "Shinny"! PV production 4.33 KWh. Turbine production 0.69 KWh.

2/16 PV production 15.22 KWh. Turbine production 0.95 KWh.

2/17 PV production 0.72 KWh. Turbine production 4.25 KWh. Stayed on grid all day, switched to grid at 6:00.

2/18 Switched back to RE at 6:21. Turbine production 9.36 KWh PV production 3.98 KWh.

2/19 Strong turbine generation overnight, 11+ KWh. PV production 20.94 KWh. Turbine production 17.34 KWh.

2/20 Switched to grid at 6:18 to heat water. Switched back to RE at 6:40. PV production 17 KWh. Turbine production 1.10 KWh. The last two days combined raised the hot water to 45C.

2/21 PV production 10.21 KWh. Turbine production 11.87 KWh.

2/22 Turbine production 6.5 KWh overnight. The turbine has become a significant generator, between the season and the added 31' elevation. PV production 19.06 KWh. Turbine production 7.94 KWh.

2/23 PV production 20.7 KWh. Turbine production 0.14 KWh.

2/24 PV production 3.99 KWh. Turbine production 4.39 KWh.

2/25 PV production 14.69 KWh. Turbine production 2.48 KWh. Hot water at 43C.

2/26 PV production 5.56 KWh. Turbine production 11.56 KWh.

2/27 PV production 2.18 KWh. Turbine production 2.57 KWh.

2/28 With 6 KWh of turbine production overnight, we are able to stay on RE. I can honestly say that raising the turbine has elevated it to a very valuable generation asset! I hope it does better through the summer too. In fact, 7:02, the electric water heater is on and very thick clouds with snow expected today, no sun out for the last two days. PV production 0.38 KWh. Turbine production 11.82 KWh.
