Analysis for 1 KW Solar Power System
Our hybrid solar solution will be designed to take care of all your lighting & energy needs. The solar plant installed will be an intelligent system that would supply majority of load through
solar power & significantly reduce your dependency on grid & DG set.This sheet will also provide you with comparative analysis done by our team of experts between
solar & other sources (DG Set & Grid Power).
AREA REQUIRED & COST OF SOLAR SYSTEM (1 KW)Approx. Area required = 11 Sq.Mts
=118.4 Sq.Ft
COMPARISON BETWEEN SOLAR AND DG FOR 1KW SYSTEM
DG System (1KW/ 1.25KVA)
Cost of diesel: Rs 52/Ltr
Diesel consumption: 0.2Ltr/Hr
Hours of operations (Assumed): 5 Hrs
Description Solar Plant DG Set
Running Cost/Year Rs. 0 Rs. 18, 720 (=52*0.2*5*30*12)
Maintenance/Year 1 % of Capex Rs. 400 - Rs. 500
Efficiency over Lifetime Generation is never Even the new system has only
below 80 % (42-45) % efficiency
Spillage & Pilferage NA 1% of the Diesel consumed.
Expected Life 25 years 7-8 Years
Utilization of Area Utilization of unused Mainly ground based,
roof-top Consuming usable space.
Noise & Vibration NA Heavy
Pollution NA Both sound & air pollution
Subsidy benefits Available @ 30 % NA

Costing of System with Battery Back-up of 5Hrs
Approx. costing of 1KW plant with 5 hrs battery
back-up = Rs 1.45 Lakhs Capital Subsidy from MNRE @ 30% = Rs 0.43 Lakhs
Effective Cost of System = Rs 1.02 Lakhs
Costing of System without Battery Back-up
Approx. costing of 1KW plant = Rs 1.1 Lakhs
Capital Subsidy from MNRE @ 30% = Rs 0.33 Lakhs
Effective Cost of System = Rs 77, 000

PAYBACK & SAVINGS
Generally the payback period for above system lies between 6-7 years.
Hence free electricity for next 18-19 years.
No. of units generated by 1Kw panel/day =5.5 KWHr
Units generated by installed capacity/year =1650 KWHr (5.5*1*300)
(Considering 300 days of operation)
Savings:
If 50% of these solar generated units (50% of 1650) were taken from grid then,
Monthly Saving from decreased Grid usage = Rs. 4, 950 (6*825)
(Cost of Grid electricity assumed= Rs. 6/- per unit)
If 50% of these solar generated units (50% of 1650) were taken from DG set then,
Monthly Saving from decreased DG set usage =Rs. 12, 375 (15*825)
(Cost of electricity Generation using DG= 15/- per unit)
Total Savings Yearly =Rs. 17, 325/-
PAYBACK CALCULATION
Commercial & Industrial users can also claim 80% depreciation in 1st
year to
save Income tax.
Terms & Conditions
Payment Terms:
o 20% advance by Demand Draft / Cheque in favour of Godrej payable at MUMBAI
along with Purchase Order.
o 65% against Performa Invoice before dispatch of the material.
o 15% against successful installation and commissioning.o All applicable taxes, duties will be charged extra on the above cost.
This sheet should be used only for rough estimation, actual quotation will be delivered by Godrej.
Without Battery Back-up:Payback = Capital Investment / Annual Saving.
= 77,000 / 17,325
= 4.44 Years
Free Electricity for 20.56 Years
With Battery Back-up:
Payback = Capital Investment / Annual Saving.
= 1,02,000 / 17,325
= 5.88 Years
Free Electricity for 19.12 Years
