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)

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
