How much water do you plan to heat?
How many degrees warmer, do you plan to increase your water temp?
IMHO, you need a much larger capture area.

I live alone so all i require is 6 gallons of hot water for a shower daily and occasional dishwasher. 300' of 3/4" Pex holds 6 gallons . I have it all constructed and filling the Pex with cold Well Water of 55 f. during a mostly sunny 90 f. day...the exiting water temp was at 158 F. after 5 hours By bypassing the water heater and having that collector water going directly into the hot water supply pipe anytime i open a hot water faucet, is more than enough for me ; in fact , Ill have to cool it down quite a bit to 100f. which means I wont even be using the full 6 gallons of collector water for showers . So yes, its plenty for this guy and is a success . Total cost was $350 and i never have to use the water heater again .
