I need to calculated area of solar collector
I have hourly hot water consumption, inlet water temperature, output water temperature required, hourly radiation data and solar faction
please tell me step by step process.
Thanks
I think the following attached paper will help you to calculate:
Dear Hamed,
If you know the radiation levels you also know the power per m².
The output water temperature is a function of water throughput.
Water has a specific thermal capacity [Ws/(K*kg)]. This might become different in value if the coolant isn't water but something different.
Check the specification of the coolant for a dedicated value
Calculating the throughput in volume/time like Liter/minute or m³/hour, the power available defines the temperature difference between inlet and outlet.
If you normalize this to a system with 1m² area and constant coolant flow, the temperature swing linearly correlates to area needed as long as you remain below the boiling point of the coolant.
Not exactly brain surgery :-)

Dear sir
First of all
1)Calculate deflation angle, solar time noon,...
2)Calculate hourly solar clearance
3) Calculate the heat loss of solar collector
4) Calculate the specification of pipe diameter and heating fluid mass flow rate
Based on above steps the solar collector area was calculated.
