Re: Our solar production

Fri Apr 01, 2016 1:05 pm

March 2016 ended with 1498 kWh having been produced. This is only 97% of last year's record of 1547 kWh and only 86% of the 2012 smaller-system record of 1350 kWh (after multiplying that old record by 1.29).

The peak production day this month was on the 29th at 82.9 kWh. The daily production record for February of 84.7 kWh was previously set on March 18, 2015.

Below are all our numbers for 2011, 2012, 2013, 2014, 2015 and 2016 along with the PVWatts predictions for the old array (PVW42: good through June 2014) and the new array (PVW54: good starting with July 2014):

Our system has produced 72.870 MWh from installation through the end of March 2016.

Net grid consumption since August 2011 (when PV was turned on permanently) has been 14.6 MWh. Solar production during this period was 72.0 MWh. Total consumption equals 86.6 MWh. Solar has provided 83% of that total.

It appears that for the first time ever we have produced more electricity than we have consumed during the past 12 months! :D We will know for sure on April 3, when we have an "official" meter reading from our electricity co-op. I will post in the "net producer/consumer" thread on Sunday with the result.

New one-week production record!

Anyone who has clicked on the solar array link in my signature has likely noticed that we rarely have strings of cloudless days around here. But during the seven days from April 12 through April 18 we had nearly-cloudless weather. Since this occurred in April when production is very high, we managed to set a new 7-day production record:

Image

That works out to an average of a bit over 80 kWh per day!

(But I will note that QueenBee has me beat by a mile in this department. Have a look at his production during last June!)

April 2016 ended with 1754 kWh having been produced. That is 101% of last year's record of 1738 kWh but only 91% of the 2013 smaller-system record of 1929 kWh (after multiplying that old record by 1.29).

Re: Our solar production

Wed Jun 01, 2016 9:42 am

May 2016 was extremely rainy and ended with 1574 kWh having been produced. That is 24% below last May's all-time monthly production record of 2069 kWh. May's result was even lower than last June's miserable production of 1585. (OTOH, the grass in the field is *literally* three feet tall.)

The peak production day this month was on the 16th at 87.7 kWh. This beats the previous daily record for May of 84.0 kWh which was set on May 14, 2015. Only two days have seen higher production: April 24, 2015 at 89.1 kWh and April 5, 2016 at 87.9 kWh.

During the past 12-month period, production was 17,665 kWh and consumption was 17,803 kWh meaning our system was a net consumer of 138 kWh. Put another way, our system produced 99.2% of our consumption over this period, including driving the LEAF 8000 miles.

Re: Our solar production

Fri Jul 01, 2016 3:58 am

June 2016 was quite sunny and ended with 1932 kWh having been produced. That is 23% above last June's miserable production of 1574 kWh and only slightly below 2014's record of 1962 kWh (after multiplying by 1.29 to account for the addition of the field array).

The peak production day this month was on the 9th at 82.2 kWh. This beats the previous daily record for June of 80.1 kWh which was set on June 24, 2015.

Net grid consumption since July 2011 (when PV was turned on permanently) has been 12.9 MWh. Solar production during this period was 77.3 MWh meaning total consumption was 90.2 MWh. Solar has provided 86% of that total.

During the past 12-month period, production was 18,012 kWh and consumption was 17,643 kWh meaning our system was a net producer of 369 kWh. Put another way, our system produced 102.2% of our consumption over this period, including driving the LEAF approximately 8000 miles.

Re: Our solar production

Mon Aug 01, 2016 10:28 am

July 2016 was sunny and hot and ended with 1887 kWh having been produced. That result just barely edges out 2014's record of 1880 kWh. Unfortunately, July 2016 was very hot with most days over 90F. The result was that net energy production for the month was very low.

The peak production day this month was on the 11th at 78.1 kWh. This falls short of the daily record of 80.7 kWh for July of 80.1 kWh which was set on July 25, 2014.

Below are all our numbers for 2011, 2012, 2013, 2014, 2015 and 2016 along with the PVWatts predictions for the old array (PVW42: good through June 2014) and the new array (PVW54: good starting with July 2014):

Re: Our solar production

Sun Sep 04, 2016 2:35 pm

Like July, August 2016 was sunny and hot and ended with a record 1932 kWh having been produced. Unfortunately, due to the heat we had significant air conditioner usage, so net energy production for the month was approximately zero.

The peak production day this month was on the 7th at 76.8 kWh. This falls short of the daily record for August of 19.1 kWh which was set on August 15, 2014.

Below are all our numbers for 2011, 2012, 2013, 2014, 2015 and 2016 along with the PVWatts predictions for the old array (PVW42: good through June 2014) and the new array (PVW54: good starting with July 2014):

Net grid consumption since July 2011 (when PV was turned on permanently and a new electricity meter was installed) has been 12.8 MWh. Solar production during this period was 81.1 MWh meaning total consumption was 93.9 MWh. Solar has provided 86% of that total.

During the past 12-month period, production was 18,121 kWh and consumption was 18,366 kWh meaning our system was a net consumer of 245 kWh. Put another way, our system produced 98.7% of our consumption over this period, including driving the LEAF approximately 8500 miles.
