We've been using small wind since around 1977, and PVs since 1981 or so. We
moved in 1989 and brought it all with us and have since installed more so we
now have about 7 1/2 kw of PVs, and our 2.5kw Jacobs generator is shut off for
need of a bearing replacement (only repair in 43 years). We run our house,
some of our heating, all our air conditioning, our Nissan Leaf, GE Elec-trac
garden tractor, shop tools, etc. on the PVs. We're grid tied now and our
electric bill for 11 months is the minimum connection fee and we usually have a
bill of around $90 to $100 in January. Our utility zeros out our account
January first so we try to use all of our banked energy by the end of December.
Before the Leaf we had a VW Golf conversion and before that a CitiCar and then
a ComutaCar. Our oldest PV panels (ca1981 35 watt Arco) still produce close to
what they did 39 years ago--I can't measure the difference with my Fluke
meters. We live in a 100+ year old farm house with updated insulation etc.,
but it's a far cry from the superinsulated house we built back in the 1970s. A
more efficient house could easily be run completely on our 7.5 kw of PVs.
