For a solar system located in Colorado, how many flat-panel solar collectors with dimensions of 1 m 1.5 m and an efficiency of 58% would be required to heat up 80 gallons of water from 65°F to 120°F during the month of January? State your assumptions.
What will be an ideal response?
Energy required to heat up 80 gallons of water from 65°F to 120°F is given by
The efficiency of the system is 58%, so the amount of energy required to intercept
Assuming 4 kWh/m2/day of solar radiation could strike the collectors that are tilted at an angle equal to the latitude of the location, the total required size of the flat solar panels is given as follows.
Considering the size of each panel is 1.5 m2, the number of the flat solar panels required
So, four (4) panels are required to heat up 80 gallons of water from 65°F to 120°F every day in January.
