The efficiency of these collectors vary depending on the solar radiation, outside temperature, and collector fluid temperature. This simple calculator will give you an idea of the efficiency and output of a collector for the particular conditions you want to use it in.
Solar Window Collector Efficiency Calculation The efficiency of a solar window collector can be calculated as follows: Where: For instance, if the inlet temperature is 75°C, ambient temperature is 25°C, solar radiation is 1000 W/m², and the collector area is 2m²:
With your ratio, you can now determine the total ft2 of your solar collector array by multiplying the total gallons per day you need to heat by the ratio you just calculated.
Divide the total ft2 of your array by the aperture area of the solar collector to determine the number of solar collectors needed for your array and you have successfully sized your solar array.
Solar noon is the time of day when the sun is highest in the sky. It can be calculated with the following formula: Where: For instance, if you are located at a longitude of 77° W and the standard meridian for your time zone is 75° W: = 12:00 PM - 8/60 = 11:52 AM 58. Solar Heat Gain Coefficient Calculation
The idea of the calculator is to give a feel for how the efficiency and output vary as the collector and the system design are changed. Output -- This is the heat output of the collector per square foot of collector area per hour. This is the the output for the specific conditions you entered.
Solar Thermal System Collector Area Calculator
Collector Area (( A_c = frac{m times C_p}{eta times Q_o times cos(alpha)} times (T_2 - T_1) )): Where: ( A_c ) is the collector area, in square meters (m²). ( m ) is the mass of water, in kilograms (kg). ( C_p ) is the specific heat of water, 4.18 kJ/kg°C. ( T_2 ) is the final temperature of warm water, in degrees Celsius (°C).

Sizing The Solar Thermal Array
Determine The Collector Area Required. To get an overall solar fraction of 60-70% (optimal sizing) of your solar thermal system, we should match the load heating requirement to the output of the solar array on a clear summer day. The significant advantage of sizing your system this way (based on summer time output) is that you will design a ...
