Life Cycle Cost Analysis (LCCA) is used for project profitability analysis because it takes into account the entire life of a project and time value of money.

Project Profitability Analysis
Fuel required per trip =2000L (Approximately)
For Electricity Generation Purpose,
Fuel required/day = 4.5L
For 10 days,
Fuel required/trip=4.5*10
=45L
Fuel cost per trip =45L*65Taka
= 2925 Taka
If we consider minimum 10 trip in a year, then fuel cost in a year = (2925*10)Taka
=29,250 Taka
Cost For Produce Electricity Present System
19
Continue…
Battery cost per year = (2*10000) Taka
=20,000 Taka
Incandescent Bulbs cost per trip = 240 Taka
Incandescent Bulbs cost per year = (240*10) Taka
=2400 Taka
Dynamo cost= 25000Taka
Dynamo Sustainability=5Year
Total Initial cost for power purpose is =29250+20000+2400+25000 Taka
= 76,650 Taka
Total cost for power purpose from 2nd to 4th year is=51,650 Taka
Total cost for power purpose at 5, 10 and 15 year is=76,650 Taka

“Impact”
To build an intelligent MPPT charge controller with Sun Tracker
Full fill the load demand through Solar
Full fill the demand considering days of autonomy
