Diameter of evacuated tube = 5.5 cm
Length of evacuated tube = 174cm
Now,
Area of one evacuated tube collector= l * b
=5.5*174 = 957 cm2
But here total 32 evacuated tube
Hence,
total area of evacuated tube collector= 957*32 =30624 cm2 =3.06 m2
Temperature of water at 9 am= 39°C
Temperature of water at 5 pm=46°C
Capacity of storage water tank = 500LPD

Now,
Input = Total area of ETC× Energy in 1 m² ×Time
= 3.06×813×8×3600
