Solar water heater system to heat 10,000 gallons 
of water daily from 25 degrees centigrade to 78 degrees 
centigrade. We need a solar system that is preferably evacuated 
tubes with heat pipe and capable of working with water pressures 
experienced in developed countries.
 
We expect that the supply will be over 276 panels consisting of 
30 tubes per collector. Each tube is 56 mm by 1800 mm 
(56 cm x 1.8 m). 

Other combination of panels and tube size that will do the job 
will be accepted.
Thank you.
