  3. 3. About the project  Owing to India’s tremendous growth in economy, the energy sector has been having a hard time in catching up with the demands of the nation.  The demand for power in 2007-08 was 46,339 mu as against availability of 40,121 mu, in 2008-09 it was 47,124 mu as against 42,199 mu and in 2009-10 the demand was 51,019 mu as against the availability of 44,549 mu. (The Hindu * )  This is where the green technology is proving its Alma-mater today. Installing independent solar energy driven pumps in houses can serve as an effective solution to the problem of power crisis.  The objective of the project is to deliver a working prototype of the system. The system should harness solar energy to generate power [Electrically or mechanically] to run a pump. This is a pilot project; hence the user bandwidth should be very small.  The product will be priced against the existing solar electrical pumping installations. Typically a fraction of the existing system. * -

  5. 5. Need Analysis  For the execution of the project a detailed need analysis must be done in the following areas:  Water consumption, patterns and issues related to the target environment  Issues related to pumping water in domestic environment  Usage patterns of the consumer  Need for alternative technology viz current systems  Alterations required to current systems t accommodate new technology  Feasibility of new system  The system is targeted at independent houses, typically of the likes of row house, bungalows, duplex buildings etc; with a typical range if 15-20mts in height.
  6. 6. How much WATER we need ? Domestic use of water  Domestic uses of water include the consumption of water for drinking, washing, bath, cooking, toilets, livestock etc.  The domestic average use per capita per day is 70 – 380 liters per capita per day  Factors affecting the use of water  Location  Climate  Time of the day  Day of the week or month 6
  7. 7. How much WATER we need ? In-house ❖ Per capita usage is 166 L/person/day, which was not significantly different from that of single residential households. ❖ Bath and shower were the main water users in-house. ❖ Average component usages for in-house use per household were: Water Privatization and Implications in India 7
  8. 8. What is available solar energy through the day?  Insolation is a measure of solar radiation energy received on a given surface area in a given time.  Ignoring clouds, the average insolation for the Earth is approximately 250 watts per square meter (6 (kW·h/m2)/day), taking into account the lower radiation intensity in early morning and evening, and its near-absence at night.  Rajasthan, Gujarat, west Madhya Pradesh and north Maharashtra receive more than 3000 to 3200 hours of bright sunshine in a year. Over 2600 to 2800 hours of bright sunshine are available over the rest of the country, except Kerala, the north- eastern states, and Jammu and Kashmir where they are appreciably lower.  In a sense, bright sunlight is available for a duration of 6- 7hrs on daily basis. 8

  10. 10. What is the pumping height ? • In each residential zoning district, no building or other structure shall exceed the following building height above finished average grade. (For 2 Storey building) Average Building Height Above Finished Average Grade 35 feet ~ 10m Source – PDF ‘KARNATAKA State construction guidelines‘ Hence, target range of head for pumping – 15-20m 10
  11. 11. Average cost for solar panel installation  For Large (Government) Projects  The primary reason for the high cost of solar power is the high capital cost.  About 50% of this cost is owing to the cost of the panels and the rest are for balance of systems.  Coal-based and natural gas-based power cost anywhere between Rs 2 and 3 per KWh; wind-based power costs slightly more – around Rs 3.5-4. Solar-based power currently costs over Rs 15 per KWh – this is for solar PV. Solar thermal costs about 2 rupees less per kWh.  For Domestic Purpose  1000 watt installation will need 70-100 sq ft of usable space.  On an average cost of Photovoltaic cells is around Rs 250 per watt.  battery backup and/or multi source system which will increase costs- Rs200.00 -300.00 per watt.  The system once installed will have a life of 25-40 years.  Battery will need maintenance and replacement lets say every 5 years and inverter may last 20 years but is warranted for 10 years so at least plan for 1 replacement in the middle of system’s useful life.  GOI pays Rs 90.00 per watt as subsidy through MNRE 11
