Experiential learning on renewable energy

sources is basically a two month training

program which develop our skills in the field

of renewable energy through & experience by

learning in various field like solar thermal,

solar PV, bio energy, densification, gasification

etc. It also devlope employment opportunities.


3/27

Following activity performed during training

Solar drying of chips and packagingA visit of photovoltaic installation,sarada

Formation of briquettes by saw dust, wheat

husk, corn cobs for testing and analysisTraining hi-tech polyhouse at RCA ,Udaipur

Briquettes can b made by two mthod

1.Binder method:-

It can be made by using binding material

like tar.2.Binderless method:-

It can be made without using binding

material.But it require high temprature.

` The polyhouses are constructed with the help of

ultraviolet plastic sheets

` The structure is prepared with the bamboos or iron

pipes.` Generally the length of the polyhouse is 25-30 feet

and width 4-5 feet.

` The direction of polyhouse is always East to West,

so that the maximum sunshine is available.


14/27

` The point of view of earning more profit only such off-

season crops should be grown, which are being sold

at higher prices in the market.

` The crops grown under the polyhouse are safe from

unfavourable environment and hailstorm, heavy rains

or scorching sunshine, etc.

` The humidity of polyhouse is not adversely affected by

evaporation resulting in less requirement of water

` insects and pests control is also easy and less

expensive.


15/27

` Constructing a tunnel below the earth of poly

house.

` Covering the northern wall of the house by jute

clothing.` Covering whole of the polyhouse with jute cloth

during night

` Fitting solar energy driven device in polyhouse.


16/27

` Removing the internal air or polyhouse out of it in

a natural manner.

` Changing the internal air into external air by

putting the fan on.` Installation of cooler on eastern or Western Wall

not only keeps temperature low but maintains

proper humidity also.

` Running water-misting machine can control thetemperature of the polyhouse.


17/27

There are 4 hi-tech poly house . Each has a area

of 00m2 .

one of them is of zero energy in which tomato&

cherry tomato are grown. Three of them are of forced circulated type in

which cucumber, red & yellow capsicum are grown

One another poly house is there in which seedling

preparation is done
