Has the industrial sector seen this kind of growth in last 5 Years .: 

Has the industrial sector seen this kind of growth in last 5 Years . Global competition is cut throat and operating expenses are rising

Hey! what is your cost of Power? : 

Hey! what is your cost of Power? Rs.3.50/Kw (unit)? or Rs.4.50/Kw (unit)? or Rs.7.00/Kw (unit)?

NO!: 

NO!

Our cost of power is : 

Our cost of power is Increased health care cost to Environment Degradation Low quality of life due to rising pollution Production losses and maintenance cost due to poor quality power supply Water shortage due to erratic monsoons and global warming Opportunity cost is opportunity loss No new power means no industrial growth No creation of wealth for citizen and state

Solar systems give decentralized & modular solution to individual institutions Let`s see some case studies

Slide for Fariyas: 

Slide for Fariyas

Fariyas Resort, Lonavala : 

Fariyas Resort, Lonavala 102 rooms property with banquets & restaurant Average hot water required @25000 to 30000 litre /day Average diesel consumption was 180 litres per day Diesel consumption cost = @Rs14lacs/annum

Solar Hot water system : 

Solar Hot water system Capacity – 100 no. solar collector Avg out put - @12,500 to 16,000 litres per day.

Solar system & diesel boiler with the hot water supply circuit modified and integrated to give maximum savings.: 

Solar system & diesel boiler with the hot water supply circuit modified and integrated to give maximum savings. Integration of existing hot water system and solar system is very important to give correct performance up to the delivery point (guest room) and fuels /electrical savings

Slide23: 

Diesel saving achieved @100 litres per day i.e @Rs.6,00,000/- per 300 working days of solar system System cost @Rs14,00,000/- (Rs 14 Lacs) 14Lacs / 6Lacs =2.3 Years (28 Months) System engineering life = @15 years (For soft water use)

PAY THROUGH THE ENERGY YOU SAVE: 

PAY THROUGH THE ENERGY YOU SAVE 100% Finance scheme Tenure – 5 Years Interest rate – 12% P.A (Reducing balance) Rs.4.5 Lacs 1st year repayment Rs.6 Lacs Diesel Saving

Environmental benefits : 

Environmental benefits 300 kg/day of CO2 emission stopped at 350oC Minimum 90 Tones of CO2 emission per 300 days

Case study IIHotel MandoviPanaji,Goa: 

Case study II Hotel Mandovi Panaji,Goa No of rooms = 66 + banquets and restaurant Hotel demand - @12000 litre per day Average diesel consumption - @ 80 litres per day

Solar system capacity –6000 litres per dayat 60o cAverage output – 6000-9000 litres per day: 

Solar system capacity –6000 litres per day at 60o c Average output – 6000-9000 litres per day Solar system and diesel boiler integrated to give maximum savings .

Diesel savings achieved - @ 40-50litres per day: 

Diesel savings achieved - @ 40-50litres per day Savings in rupees – @Rs800 – Rs1000 per day Yearly savings - @ Rs.3 lacs/300 days

System cost - @ Rs.8.5 lacs Diesel savings - @Rs.3 lacs: 

System cost - @ Rs.8.5 lacs Diesel savings - @Rs.3 lacs Simple pay back  Rs.8.5 lacs / Rs 3 lacs = 2.8 years (34 Months) System life 15 Years

Pay through the energy you save: 

Pay through the energy you save Finance scheme from IREDA Ltd, New Delhi. Amount – Rs.7 Lacs Tenure – 10 Years Interest rate - @7.3% P.A (Reducing balance method)

Slide31: 

Moratorium period – First 2 Years (Only interest payment to be done) Rs.1.3 Lacs 3rd year loan payment Rs 3 Lacs Diesel savings First 2 years already save Rs6 Lacs,So repayment is through the cash positiveness itself.

Environmental benefits : 

Environmental benefits 45 tons co2 emission stopped at 350oc

Average Saving per month Rs.14,583-00 Saving in % Rs.27.5% Saving Per Year Rs.174,996.00 TOTAL COST OF SOLAR INSTALLATION = Rs.4.5 Lacs PAY BACK PERIOD 2.6 YEARS

Contribution by hospitality industry to the GRID by using solar hot water system: 

Contribution by hospitality industry to the GRID by using solar hot water system Example: 200 to 250 hotels of 30-40 rooms capacity Can Reduce Peak load demand by 2.5 to 3 MW

Slide39: 

In effect, in our power sector set up(with all the T&D,theft and subsidies)we save 6 MW per day which can be diverted to another industry. 6 MW means Rs24 Crores of capital investment which is saved. The solar system investment is of @Rs.12Crores only & 6 MW h/h of power is sold everyday to another industry. This is indirect capacity addition for inductive load which is nothing but industrial growth.

Conclusion : 

Conclusion Heating water by electricity is a waste of our limited power resources. Using diesel for water heating will only add to the pollution. Indian society requires a paradigm shift in it`s view point towards energy resources and it`s end use. Solar system is the practical, cost effective de-centralized smart technology to solve our national power crisis. Solar systems are our most effective weapon for creation of national energy security
