5. MICRO-GRID
❖It is a small-scale power supply network that is designed to provide power for a small community. It enables local
power generation for local loads. It comprises of various small power generating sources that makes it highly
flexible and efficient.
❖It is connected to both the local generating units and the utility grid thus preventing power outages. Excess power
can be sold to the utility grid. Size of the Microgrid may range from housing estate to municipal regions.
❖Villages can now have access to electricity by investing in their own microgrid power plant. The size of a solar
microgrid depends upon the number of solar panels and wattage comprising the solar array
❖The requirement and size of a microgrid is calculated by adding the power needs of individual homes in the village
that will be connected together.
Benefits Of Micro Grid:
• Transmission Losses gets highly reduced.
• Provide High Quality & Reliable energy supply to critical Load.
• Microgrids can generate revenue by helping communities
and businesses to provide energy services to the wider grid.
• Reduced Fossil Fuel Use.
• Reduced capacity charges

6. MICRO-GRID

7. Solar water pump
❖A solar energy-powered water pump is a water pump running on the electricity that is generated by solar
photovoltaic modules.
❖Solar water pumps basically consist of three main components:
1) the water pump
2) solar photovoltaic modules
3) pump controller (and inverter)
Benefits
❖100% irrigation can be Achieve Through solar energy

• Dependency on Diesel Reduce.
• Can be installed in remote areas where electricity is unavailable or diesel is difficult to procure.
• Low Labor & Maintance Cost.

8. Solar Water Pump
Problem
• Agricultural Irrigation in India is hampered by the Erratic Electricity supply in the rural India.. Farmers get 7-8 hours
of electricity a day. They pump when electricity is available rather than when the crops need it.. This leads to water
waste and adverse impact on crops. Diesel pumps have high operating costs due to increasing oil prices.
Solution
• A Solar Water Pump extracts water from water well and collects or sprays over the field. It uses Sun power for its
operation via Solar panels. Hence it operates free of cost as against conventional Electric/Diesel Pumps. A DC
electric pump is connected to the Solar panel, hence no Inverter is required. A Battery may be connected in order to
operate the pump during Night/No-Sun Conditions.
Different types of pumps Initial Capital Operating cost/Year maintenance Dependency on grid
Electric Pump Low Medium Medium Yes
Diesel Pump Low High High No
Solar PV Pump High Low Medium Partial

15. Solar Dryer
❖Solar dryers are devices that use solar energy to dry substances, especially food. There are two general types
of solar dryers: Direct and indirect.
❖DIRECT: Direct solar dryers expose the substance to be dehydrated to direct sunlight. They have a black absorbing
surface which collects the light and converts it to heat; the substance to be dried is placed directly on this surface. These
driers may have enclosures, glass covers and/or vents to in order to increase efficiency.
❖INDIRECT: In indirect solar dryers, the black surface heats incoming air, rather than directly heating the substance to
be dried. This heated air is then passed over the substance and exits through a chimney, taking moisture from the
substance with it.
PRINCIPLE OF SOLAR DRYER
solar dryer is based on two principles:
1. Conservation of energy in which one form of energy is converted into other form of energy .
2. Black body which absorbs the heat of the incident sunlight and makes the temperature of chamber more than the
surrounding temperature .
Need Of Solar Dryer
• In rainy season and winters due to presence of moisture a foul smell develops in food grains and there is full possibility
of development of pests

16. Solar Dryer
• It can also be used as filter.
• It make us rid of spreading food grains which was required earlier at regular period of time
• Drying in the direct sun has the risk of damaging the complete harvest by rainfall
• Dehydration of fruits, potatoes, onions and other vegetables Seasoning of wood and timber
Advantages:
• Much less time is required for drying as compared to direct drying because
of black body
• Protection of the drying products from insects but also from birds, dogs,
especially for drying meat and fish
• The product is hygienic because microorganisms, insects and flies are killed
• Protection of rain
• Protection of pollution by dust etc.
• Protection of the wind which can blow away the food

17. Solar Insect Trap
❖SOLAR INSECT TRAPPER is a solar energy-based insect trapper can trap many pests and helps farmer to cultivate
more quality and quantity of crops.
❖ since farmers faces the problems of various types of pests that harm crops right from sowing till the crop harvested, This project
uses UV LEDs were safer than using ordinary fluorescent lamps.
❖India is a tropical country, solar power is readily available and also it requires less maintenance. The device seems
promising to farmers since it has been capturing adults of many pest, borers, and flies thereby reducing the
dependence on bio pesticide usage to the tune of 50% .
Principle
• Insects are attracted to UV light source and Solar trap is designed to exploit this behaviour.
• Solar Insect Trap is fitted with a current carrying mesh to electrocute the trapped insects.
• Electricity generated from the solar panel is stored in a battery, which then powers the UV tube and the mesh.

20. Solar Home Lighting System
❖A SHLS is typically a Battery powered system that is charged using a Solar Panel. The energy stored in the battery is
then used to illuminate one/more rooms of your home or shop or classroom. These systems can also offer mobile
phone Charging and the ability to charge the battery using AC wall socket.
❖Having no access to electricity, rural areas use kerosene lamps at night for indoor lighting and for undertaking urgent
family tasks outside the home.
❖These kerosene lamps and lanterns use the heavily subsidized kerosene. These being some of the most polluting
energy sources and the majority of rural homes being poorly ventilated, use of kerosene lamps poses an increased
health hazard, causing respiratory and eye problems.
❖ In addition, inhalation of the fumes affects the longevity of women involved in many of the household chores. The
use of kerosene lamps is also a threat to safety.
❖Lamps can set fires in rural homes which are largely made of straw and mud. The light of these kerosene lamps,
which are the open wick type (commonly used in rural India), provide low lighting intensity, far below that is
required to meet reading needs adequately. Thus education suffers as well.
❖Solar power has proved to be very successful in replacing Kerosene lamps and providing basic necessity of life,
electricity, to people.
❖Solar energy, today, has become an effective and environmentally sustainable source of light. Use of solar power has
scores of advantages. It averts the health hazards of kerosene lighting, which is alleged to be the reason for hundreds
of deaths in India.

21. Solar Home Lighting System
❖A Home lighting systems: This consists of a complete installed unit, namely a solar PV panel, a battery, a few meters
of wiring, and lighting bulbs.
❖Lanterns: This also requires almost the same equipment. But here the battery unit and the lighting bulbs are together,
and can be taken to various locations once they are charged.
❖Community center or school lighting systems: Almost similar to the home lighting systems, except the fact that here
the system is larger in size to generate more power.
Benefits of the Solar Home Light system
A leap towards children's education: Most parents met during the field visits mentioned that the reading habit of the
children had increased. They study during the evening hours. This is especially true for those villages which have
regular teachers at the village school.
Improvement in health: With the solar systems in place, fewer women will tend to suffer from respiratory problems.
Kerosene fumes will cease to affect the eyes of the family members. Winters being cold, the houses are kept shut all the
time, and the kerosene lamp emits so much carbon that not only do the eyes burn, but also respiratory problems
develop. Women are affected much more severely than men since they stay at home for much longer hours.
Saving of money:In several houses, the supply of kerosene, which is normally 3-5 liters a month, comes from the
ration shop. This consumption has stopped entirely or reduced drastically, helping the family save an average of INR
50 a month. The savings can go up to INR 100 for families which do not have access to subsidized kerosene supplies
(which is also quite erratic in the area). This is over and above the hardships one has to face to go all the way to the
ration shop which is normally about 3-4 km from the village, only to find that the shop is closed or that kerosene is not
in supply.

22. Solar Home Lighting System
❖The other monetary benefit is the saving of money households spend on charging the mobile. This amounts to a
savings of another INR 100 a month. Again, the benefit is also non-monetary as it is handy to charge the same from
solar light when needed, rather than banking on someone going to the main market about 15-20 km away for
charging it.
❖Increasing safety for the family: The benefits go much beyond financial calculations. For example, the light helps
one to see that there are no stray insects in the food while eating, that no scorpions and snakes are around etc. These
are benefits which are directly linked to the lives of the family members. Also, the light enables young mothers to
nurture their infants at night and also help women working on manual flour mills. These are examples of benefits
experienced by women. The safety which the Dayan (midwife) feels with the solar light on during delivery of a child
at home is a benefit that goes much beyond finances.

23. The sun is a powerful source that can help our
planet by giving us clean, reusable energy to
power our world. The use of this energy is free,
does not create pollution, and if used wisely can
help us become less dependent on other more
costly and damaging forms of power
