INTRODUCTION
Solar power village is a self sufficient village which does not depend on external sources for energy.
It was developed by UNESCO.
It aims at bringing renewable energy to rural areas.
Doesn’t require supply systems.
MAIN COMPONENTS
Solar Envelope
Hot oil storage tank
Middle temperature Sterling engine
Sun Pulse
Disinfection system
SOLAR ENVELOPE
A light weight structure covered with special foil which is transparent for UV radiation also.
Acts as a substitute for pesticides
An optical system absorbs the heat and transfers it to insulated pipes containing oil .
HOT OIL STORAGE TANK
A tank with 2000ltrs of oil.
Stores the hot oil at a temp of 220 deg.
Stores of 75KWH of useable heat
Provides heat for Sterling Engine and cooking stove
STERLING ENGINE
Transforms thermal energy into mechanical work
Works even at 150 deg
Used for corn-milling
To pump water or for cooling
SUN PULSE
Low temperature sterling engine to pump water
Pumps about 4cbm/h water from 10m depth
Consists of a hydraulic ram which in combination with sun pulse can pump water from 60m depth
DISINFECTION SYSTEM
Can be employed to disinfect water with solar radiation
Uvitt is powered by electricity which generates UV radiation of high intensity for disinfection
ADVANTAGES:
Reduce the dependence on fossil energies
Slowdown the exploitation of limited resources ,deforestation and stop global climatic warming
Support local economies to make health, prosperity and education attainable in all regions
Preserve ethnic and ecological values.
DISADVANTAGES:
The only disadvantage is that it doesn’t properly work in rainy season
CONCLUSION:
Owing to the depletion of non-renewable resources, Solar Power village is an integral concept to use energy and also to create stable local jobs in INDIAN RURAL AREAS
