SOLAR POWER V/S DG SET COMPARISON

COMPARATIVE STATEMENT for SOLAR POWER V/S DG SET:

RECURRING EXPENSES

A) EXPENSES ON DIESEL GENERATOR OF 5 KVA

Price for 5KVA Generator = 1.3 Lacs

Diesel consumption per hour = 1lts/hr
Price of diesel = 48.16/Ltr
Cost for one Hour (1× 48.16) = Rs 48.16/-
Diesel Consumption per day = 48.16×12 Hrs =Rs 577.92
(Assuming 12 Hrs working a day)
Diesel Consumption for one Month =577.92×30=17337.6
Diesel Consumption for one, year =17337.6×12=208051.2
Diesel Consumption for 10 years =208051.2×10= Rs 2080512

B) DETAILS OF EXPENSES ON SUN POWER GENERATOR OF 4KWatt

INITIAL COST

Price for 4K Watt Sun power generator = 6, 40,000.00

Installation Charge = 50,000.00
TOTAL 6, 90,000.00
Replacement of battery every 5 years = 3, 24,000.00

(AH=(4000W/180V)X12 Hours/0.8=333.33. efficiency=0.8

No of battery 12V/190AH=(180/12)X333.33/190=26.31 =27

Cost of battery 12V/190AH= Rs. 12000x27=Rs 3, 24,000)
Total cost for 10years = 6, 90,000.00+3, 24,000.00=10, 14,000.00

Difference between (A-B) 20, 80,512- 10, 14,000 = Rs.10, 66,512.00

Income earned by using sun power generator is Rs. 10, 66,512.00

Note: it is assumed that general maintenance cost of solar and DG set is same.
