System architecture
Estimation of specification
and components
 Total load=13.340kwh/day
 Average Insolation=3.96kwh/m2/day
 Peak load Pdc=3.37kwp
 The average inverter efficiency=90%
 Load=(3.37/.90)=3.74kwp
 Per panel=150W
 So panel required=(3740/(150*.80))
=32 panel
 No physical Net meter
 Power consumed from grid= power
Supplied to the grid

10. Calculation of the cost of energy
Estimation of energy delivered:
 Total Produced Power per year=13.340*365 Kwh/yr
=4869.1365 Kwh/yr
 Total produced in 20 years=97382 Kwh/yr
 Total cost in 20 years period=781950 tk
 Cost per unit=8.03 Tk/kwh
Conclusion
 Selling price per Kwh of BREB= 5.63 Tk/Kwh
 Cost per unit in our system= 8.03 Tk/Kwh
