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.

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.


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 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.
