Solar Collectors

One of the key advances over the past 20 years has been the development of affordable and cost effective evacuated tube collectors. If you live in an area that one would not consider very sunny, it is important how your collectors will function on partially cloudy and cloudy days. This question becomes even more important in those areas during winter when it is cold. Flat plate collectors loose too much heat to be operable in cloudy or partially cloudy weather in very cold climates.

Every tube on an evacuated tube collector is like a thermos bottle. It holds on to the heat it collects from the sun, even when the heat is small, thus allowing your hot water to be heated for your home.

Sunrise through two FC4715-30D's setup to track the sun from East to West. This array seeks the brighest spot in the sky and adjusts itself once every 5 minutes for a period up to 5 seconds. Tracker has reverse lock out. Tracker board made by Model LED3X with reverse lockout and night time reset.

These are two FC4715-30D's mounted on a roof with Elephant racking to steepen the total angle a bit. In this example, all piping and insulation is complete just prior to tube insertion which is the last aspect of assembly. The system is fully functional once the tubes are inserted and usually starts to "cycle" when the tubes are being inserted. This system happens to be a DPDB with an 80 gallon storage tank.

UPDATE 6/21: Under 'My Solar Home' above, Geo-Theraml section, new heat pump shown and described.


April scooped by May.

05/01/2021 new record, 123.0 KWH!!

I think unless the new "record" breaks the old record by at least 1 KWH, I won't bother noting it here.


April BIG BANG!!

It is April 26th, still Earth Day week, and we did it again. WE broke another single day production record today, beating last year's Earth day (April 22nd) single day production record of 119.0 KWH. TODAY we produced 122.8 KWH!!

March Madness!!

Already in the first half of March, 2021, there have been 7 PSD's (Perfect Solar Days) for an unprecedented 1255KWH's for the period!! This is only 130KWH's less than the whole of March last year, which was in and of itself the previous March record!!


Update: Well its 3/31 and the month is officially insane!! 10 PSD's and an all time March record of 2180 KWH's!!, 795 KWH's above last March!! We have never had 10 PSD's in ANY month let alone March!! So far, '21 is LOOKING SUN GOOD!!

What's New

01/12/2021 My new GEO heat pump is finally installed. I have been "tweeking" it until today, 01/16/2021. It works GREAT!! Unlike it predecessor's, it actually performs up to its submittal sheet. LOVE IT!!

I finally finished my electric overhead to underground conversion along with the transformer upgrade (15KW to 50KW).


May Monthly Production Record  Gets blown away in June at 2517KWH !!

Monthly Production record stands at 2163KWH for May 2020.


Happy Earth Day !! New production record, again. 119.0 KWH 4/22/2020


Had some clouds, no snow field of course. If no clouds and a snow field this time of year, probably 125 KWH with the upgrades.


NEW production record!! 110.5 KWH on April 6th!!


Made changes to my PV tracking system. The main PV inverter was upgraded from an SMA SB-US-8000 to a Fronius Primo 11.4 (11,400 watts). Additionally, the PV arrays were upgraded with 20 SunPower 327 watt modules leaving 16 of the original Canadian Solar 255 watt modules, bringing the total output of the array from 9.18KW to 10.620KW. The combination of the inverter upgrade coupled with the array KW upgrade, should generate an additional 2 to 3 MWH a year. I hope this will compensate for the increased cloudiness being produced by Green House Gas Heating Climate change. It took a fair amount of work to do all this....


UPDATE: All 36 modules are being changed out which will result in an array output of 11,772 KW. On a very sunny year, 20 MWH should be within reach.


PV Yearly Production Numbers


2020 PV Production is  19.375 MWH which is a new record buster.!! The only month that did not gen more than last year was October. Our usage was up due to more driving and general increases, which the increase in production was able to satisfy. That production defers about $2000.00 worth of power from the grid.


2019 PV Production is 16.787 MWH.

2018 PV Production is 12.463 MWH.

2017 PV production is 14.293 MWH.

2016 PV production is 15.629 MWH.

2015 PV production is 14.543 MWH.

2014 PV production is 7.711 MWH, first year partial production. 9.374 MWH were produced through the entire startup test phase of the system before certification.


2019 production was a record breaker, do to the upgrade being active for 1/2 the year along with being decently sunny. Most likely, if the array upgrade had been active for the whole year, 17 or 18 MWH's would have easily been had.


2018 production was the worst production ever, not only for PV but for all solar. The rain and cloud cover was unpresidented! WE blew right through the 13 Megawatt range and landed in the low 12's. An increase in array capacity might be necessary to adapt to the GH GH'ing realities causing climate change, to resore a slight electrical surplus.


2017 production down 1.34 MWH from last year. All months produced less except for December which is the cloudiest month of the year.... Ironic...


Electric  car miles for the fifth year are 15863 saving 690 gallons of gas at an avoided cost of $1932, bringing the five year total to  $9172.00. Covid-19 reduced mileage, but a third car (Bolt) and a third driver beginning in August, over turned the shortfall.


Electric car miles for the forth year are 14037 saving 610 gallons of gas at an avoided cost of $2014.00 bringing the four year total to $7239.00. Gas went up and down over the period.


Electric car miles for the third year are 13,220 saving 575 gallons of gas at an avoided cost of $1955.00 bringing the three year total to $5225.00. Gas prices steadily climbed throughout the year. Total number of gallons not used stands at 1790.


Electric car miles for the second year are 14,830 saving 645 gallons of gas at an avoided cost of $1870.00 bringing the two year total to $3270.00. Not bad for only 2 years at fairly low gas prices...


Electric car miles for the first year ran about 13,000 miles of energy free driving. The gas saved which would have been burned by the car that the Leaf replaced equals about 570 gallons at an avoided gas cost of $1400.00.


Total mileage across the three years equals 41,050 miles. At a gross electric usage of 3 miles per KWH year round, this translates to 13.68 Megawatt hours of electricity, or 4.56 Megawatt hours per year. With the addition of the Ford C-Max plug-in Hybrid over the last year, the total transportation electric load is increased by about 2 megawatt hours more, bringing the household trans electric yearly load to about 6.6 megawatt hours.
