Determine the number of colectors required and the cost of auxiliary power in a facility that provides hot water to a community of 34 residents. Which would be studied the benefit of placing the panels tilted at 18 degrees relative to the horizontal place because installers additional 3 dollars charged per m 2 of the collector by installing inclined. The characteristics of the system are:
Daily consumption: 55 liters / user
Area sensor: 2.06 m ^ 2
Efficiency equation: n = 0.77-5.88T
Temperature: 45 C
Auxiliary Power: Electric ($ 0.22 / kWh)
Inclination for sensors: 0-18 (degrees)
Monthly Occupancy: 100% except in the months of June, July and August which vary from 95%, 85% and 90% respectively
