We reached a total charge of 50000 amp-hours on October 17, 2008, almost exactly 5 years after exposing our solar panels to the sun for the first time. An average of 10000 AH per year to fuel the electric needs of a family of three, plus running a part time wood shop building small sailboats. This is not much. Some friends use that amount in an afternoon.

The system still works perfectly, with a minimum of needed maintenance. Nothing has broken, nothing have been replaced. We can proclaim it an absolute success!

The socalled weak link, our battery bank comprised of four Trojan 105, is still the original. The estimated life is 4-5 years, but with a care it seems likely that we will be able to extend the use of these little units a bit further.
