I have a solar house in the Caribbean. It uses 16 of Trojan T105 cycling up to 50% daily.
After 6 years, 15 are still usable but probably with capacity reduced to 50% and one just failed. Pretty good performance.
The panels cover about 200 sq ft and generate 1kw in full tropical Sun and 5Kw hours per day.
