Solar Water Heater
Not what you're looking for?
The average home has a 200 liter (50-60 gallon) hot-water tank, which is effectively drained and replenished three times per day. Assume that the entering tap water is 16 degrees C and is heated to 56 degrees C. Given an average energy from sunlight of 1.53 kJ/cm^2 per day, how large would the collection area (in m^2) of a solar water heater need to be if its efficiency is 29%? Assume that the price of a solar collector is $370/m^2. How much would it cost to install this hot water system?
