Excellent mid-day every person. My name is Chetan Singh Solanki. I am a faculty at the Department of Energy
Science as well as Engineering (IIT Bombay). And also I have actually done my PhD in solar power modern technologies
back in 2004. So, the last 15 years, I am working with this
technology, and I have actually been trained to create the technology on solar cell. What likewise we are doing at IIT Bombay is, I.
am heading what is called NCPRE which individuals went to National Centre for Photovoltaic Research Study.
in Education where we are actually type of researching on the extremely fundamental aspects of the products, solar cell layout, fabrication of solar batteries,.
components, integrity of modules, power electronics, whatever under the sun that you require to know,.
from right from the product till the assimilation with the generation of power integrate, everything.
we are doing it.But as I claimed, what I am not mosting likely to talk.
to you is concerning modern technology. Whole lot of us in fact establish a, really fantastic.
innovations yet not every technology reaches individuals. As well as as a result this experience that I am going.
to show you, with my colleague Mr. Chandran, we have been working with this task together.
for several years now, is an example of how that can be done. So, the solar job is called Solar Urja.
Light project, you know, SoUL, as well as it is truly touching to the hearts of millions, millions.
of students. Solar Urja lamp is in fact the lamp for.
study function. Prior to that allow me offer the background.
that there are 17 lasting growth goals, you could be conscious concerning it. One of the objectives, that is goal number 7 is.
a really important goal. What it claims is, ‘make sure accessibility to affordable,.
trustworthy, modern and lasting power for all’. It has to do with energy but it touches every other.
lasting development goal whether it has to do with the Hardship, whether it has to do with Literacy,.
GDP, Earnings Empowerment, or also Environment Adjustment, everything as a relationship with this objective.
number 7.
So, basically I intended to tell you in 2017,.
what is the condition of the globe, you recognize. 1 billion individuals still did not have accessibility.
to electricity. 1 billion is nearly 13-14% of the world population. 2.8 billion People did not have accessibility to.
tidy cooking, 40% of the world populace. So they would be using biomass, cow dung,.
timber, coal type of, you recognize. Can you visualize this circumstance? That we are in the modern, the most modern-day.
globe and also we have all type of technologies reaching to the moon and Mars and also what not? Regarding 40% of the individuals in the world still.
do have access to clean food preparation. The worst issue is, usage of power is.
influencing the climate adjustment. So whatever action that we do making use of energy.
it is impacting the climate change. Since power drives our, and we require energy.
development but on the other hand energy is likewise resulting in the environment change. These are the two opposite ends of the.
issue. For Indian point of view specifically,.
but it is really not only India'' s viewpoint, lots of countries are passing via this stages.
We require a great deal of power. And India additionally imports a whole lot of energy from. We are one of the most significant importers of coal,.
is nearly about 1000 systems. And if we pass the standard of the globe that.
has to do with 3500 devices, you require 800 thousand megawatt of power plant capacity in India. Currently we are regarding 350 thousand systems. So, once more massive ability addition is required. Since you, why I am placing this context.
need to comprehend that this course if we remain to stroll on this path, you know, it is not.
truly mosting likely to offer sustainable solution. Why this light which I am going to speak about.
is extremely important because education and learning is very enabler, wonderful enabler in every nation. And in India, especially, a great deal of pupils.
in a rural area is nearly greater than 70%. As well as if you check out the variety of enrollment.
of the students in an urban location and also in a rural area, you will certainly find that the dropout.
prices, i imply the contour is much steeper.The yellow one is much deeper for the pupils. in the rural area
as contrasted to urban location. Currently, there can be several factors for that you. recognize. Access to the college itself
, the educator,.
the quality, everything, but among the factors that is essential, that plays a function here.
is accessibility of electrical energy. Till and also unless there is a dependable, electricity.
services are offered to them it does not function, the continuity of education is not there. So as an outcome of that, several nations about.
the globe, what individuals do is provide them solar lamp. Why because solar lamps are very easy, standalone.
gadgets. You can get it in supply it and also you can supply.
it in an extremely promptly. If someone actually intends to give a basic.
In India? If you look at the initial kind of solar.
light came in India in 1976. It is practically more than four years that.
such a programs have actually been taking place however it is not extremely successful. And also that is where the advancement that we are.
done, in regards to the innovation, in regards to the procedures, in terms of the materials,.
in regards to the supply chain.Everything is really essential. That is what I am mosting likely to show you. Before that allow me show a small video to put.
the entire thing in a context. Could you discover, what is the option? Solution is naturally a solar light, yet the.
method we give the solar light is very vital. And also as I stated that what we do is we include.
regional neighborhoods to do each as well as whatever. However exactly how we have pertained to this suggestion. I wish to share 2 type of task.
which did not function effectively. Among the task which we began in 2008.
and 09, Ekal Vidyalaya is like a one college educator and also these are the really casual colleges,.
run in a very remote backwoods where children go to the field in the daytime and also they could.
not gain access to the routine school.So they actually go to the colleges in the.
evening. When I went very first time to this village in.
center of someplace, you recognize, we quit and I stated most likely we lost the road. They said no sir. The location where you are standing is really.
the road. We could not even figure out the methods.
to reaching to this village as well as there are many villages like that. I located what individuals used to do is research like.
this in kerosene lamp, and also so this Ekal Vidyalay’s what will individuals do, they will certainly take a kerosene.
lamp, they will certainly walk to the institution. The school is extremely informal as I claimed. It is in somebody'' s home they collect together.
and also research in the kerosene. So what we have actually done is, we have actually provided.
them a solar light. Now back then this lamp is as you can see.
Pradesh, also this image I believe belongs
to Tamilnadu somewhereSomeplace One of the issue of this kind of strategy. Why put on ' t we put it, you recognize, above the ground?
else. After that we claimed why put on ' t we hang it upside. down. So what I have done is, I have actually divided
the. base of the light. This is a really old photograph. In some way I got gain access to, and after that we attached.
one more wire in the light was hang on the top so that means the distribution was fine.Well these were some of the experiments we. did however within 5 month, 6 months, 7 months the light stopped operating
. In some cases, the battery will not
be billed,. the fuse will certainly not be working. Or perhaps if some individuals, you recognize, tell us. that also my light is
not working, we couldn ' t do anything, because there is no other way we could.'connect to many different locations.
At the exact same time, I did one more task as. I stated, with the TERI that a, Light a Billion Lives task where the whole version was a.
little bit various what, in this design was that you in fact produce a central charging station,.
fee all your lights at one location. The individual will really pay the rental fee for making use of.
it. The customer will come to the centre, take.
the light in the night the charged lamp, use it over night and afterwards bring it back in.
the early morning to ensure that it can be charged once more. So, I did 3 villages with this kind of.
model, you understand, in my village, as well as the neighbouring villages.But the, after
5-6 month, one year it was.
the very same, the lamps stopped functioning. Nobody will involve repair it, lights were.
Expensive, so people might not manage it. So, in 2012, so one of the problems that I.
identified is this device of ‘Purchase as well as Market’. What everybody will do? State federal government, Central Government, NGOs,.
for those that were running the program, they would purchase and also sell, because of this the core product.
will certainly end up being expensive. Why? Somebody will due to the fact that someone will certainly make it.
acquire it, after that it will be transferred. 2nd problem I determined is that there.
is no technological assistance. Numerous times a lamp is an extremely straightforward gadget.
and also the problems that were with the light were extremely straightforward. In some cases the fuse in the light will certainly not be.
working so you need to alter the fuse. In some cases the soldering factor will, you know,.
obtain off so you require to solder it once more. Occasionally the, the battery will certainly not be an effectively.
charged, so it is an extremely easy thing.But as an outcome of this the product will really. fall short prematurely.
As well as that is the situation not just with the solar. 500 lights, if someone wants to purchase
one more lampLight (sayState 501, it is not available.Right? As a result of that, the Solar service never ever.
So you recognized? Everyone? So this is a fundamental issue. Not just this technology, I believe with every. modern technology. Your cellphones are working all over. due to the fact that you find some guy who can actually offer recharge of 10 rupees also. You can locate somebody that can actually repair. phones in every corner. So, comparable point was called for. And not just required, after that we additionally located. If there is electricity link in the homes of people still solar light is, that even. needed, due to the fact that when we talking about study objective, for researching you need about 150 Lux. of light.Lux as an unit of light, you measure just how much.
That is the kind of strength that we need. We measure this in numerous residences, virtually.
What is this inform you that also if there is. The range between the light and the. The light will certainly be typically hanged in between.
Therefore it will certainly be dispersed to wider. And also another trouble also if there is electrical power.
There is a power cuts. All those examples will certainly be taking place. Together, initially of all, when there is no. electrical energy we require a remedy.
That is what our lamp can imagine. People need electrical energy or power for fundamental. This is the entire energy ladder that we.
required to function. However one of one of the most standard points is giving.
them light for research objective as I informed you earlier, that we wished to resolve this issue. of accessibility to the light to ensure that everyone can study well.
Now, the 3 problems that I have told you,. we assumed there could be 3 services.
Solutions included: How do you find as well as make. the item cost effective? Just how do we entail the regional community? and also, Just how do we saturate the area with which. we work? Incidentally, the program for 1 million, Solar. Lamp, you recognize, that we assumed we executed it from IIT Bombay.1 million is a large number by, by any type of standard. And also we desired to do in one year time, so.
the rate of the entire procedure, the range of the entire procedure and the skill that.
is required in the regional community was, was very important facet of it.
Solution is of program a solar light, however the.
500 lamps, if somebody desires to acquire
one more even moreLight (say) 501, it is not available.Right? That is what our light can picture. Individuals require electrical energy or energy for fundamental. Lamp, you know, that we believed we implemented it from IIT Bombay.1 million is a large number by, by any requirement.
