Bifacial solar panels with glass on both sides can capture energy from direct sunlight and reflected light from the ground surface (albedo effect), achieving approximately 6% higher efficiency than traditional monofacial panels. This technology enables solar plants to achieve capacity factors of 35% or higher, significantly outperforming conventional systems.

జమ్మలమడుగు నియోజకవర్గంలో SAEL కంపెనీని సందర్శించిన విద్య, ఐటి శాఖల మంత్రి నారా లోకేష్.Added:
Hello, boss. How are you?
I'm good. How are you? Great.
We did it in 11 months.
It's all your hand holding. It's all your hand holding and uh How are you, sir? He's the next generation uh CEO of the Oh, nice. How are you, Lokesh? Thanks for coming. How are you, sir? How are you, sir? Good here, surviving.
Thanks to you.
Ravi, hi, boss. Come.
Energy minister.
Namaste. How are you, sir? Come.
When did you come?
Yesterday. Yesterday, all good. We drove from Bangalore.
Nice road. Very good road, but I I was talking to the driver on the way.
Uh-huh. He was very I was happy to say good words Oh, good.
>> [laughter] >> They'll give you the right feedback.
That's the No, no, see, economic activity has to come, no?
Hello, sir. Hi, sir. How are you?
How are you? Very nice, sir. How are you, sir? Good, good, good. Namaskaram.
How are you?
Namaskaram.
How are you?
This is your command center, no? This is the main main main control room and this is the SCADA system. Supervisory control and data acquisition system. Currently, sir, 291 MW is running. Plant capacity is 300 MW, but due to clouds, there is some downfall in the and the plant is performing optimally.
Uh in per year, we will be injecting around 1,550 million units of energy, and it will help us power on 75 lakh homes per year.
And the plant is performing very good, and we have this top one by facial model installed in our plants, and the whole system is on tracker system. It's on tracker, I saw that, yeah. The latest technology we have adopted. How much is a megawatt now costing the tracker and without tracker what is the price difference The price difference it is around 30 to 40% there is a variation in the 30 to 40 wow That's a lot In my past life in the private sector I did a solar plant for captive that that obviously did not have tracker so there's always this debate tracker versus non tracker debate We actually started working because of stock phone modules Stock phone modules okay Because before this tracker did not work for many years people did not use trackers Tracker so what's the difference between this module and a regular module In the this bifacial modules we get this albedo effect because there is a diffuse radiation which gets reflected from the soil surface we cannot initially we will not be able to harness that energy now we are harnessing that energy also which is coming from the reflection of the soil surface Also you're saying the top one is the sun Yeah So a lot direct and you're saying the bottom also you've done so where the reflection coming That's called the albedo effect Albedo effect We have glass on both sides now Oh Glass on the front and glass on the back Oh wow Which is by albedo effect and it's the efficiency is higher 6% bifacial 6% Down side is 6% Oh wow 520 21 is coming You guys got it over there And the initially the the CUF that the efficiency that it was coming it was around 19 to 21% for the older models right now it is 24% 24 Bifacial Bifacial is 24 24 But the CUF of this plant is touching 35% also Which is much much higher than So you should pay the government more You like 35% we have understood you spilled the beans No no no So is it why because of the what is the reason why you're able to get so much more On tracker and the radiation is also better here. He is earning money on that. They are only going to pay us up to 34%. 30 30 30 30 30 30 30 30% 30 And rest is free to them. Ah.
>> [laughter] >> No, no.
The energy ministry is in a lot of stress.
Because CM said we have to reduce the cost of power.
At price at which we are purchasing. So every month the CM is now tracking. We have reduced about 38 38 paisa we have already reduced. You see CM's directive to us is reduce by 1 rupee.
Procurement price. So now we are trying to become more efficient. We have to compete with the private sector.
They have a sticky PPA.
Yeah, sticky PPA. This goes to say. They have promised for 30 PLF. Yeah, 30 PLF.
30 PLF. 30 PLF. But the plant is Plant is already achieving a More than 30 PLF.
See, he is smart. He is saying higher PLF. He is not telling me the numbers.
Is this the entire land? The entire land. The entire land.
But there is only 3 and 1/2 acres which we didn't get, sir. Which is where?
Which one is that? M3, huh? Next to ICR 6. ICR 6.
Otherwise the whole Ah, which one is that?
I'm going to die.
Where are we right now?
ICR 1. ICR 1.
You good? Sir, for just a gesture of inauguration, sir, can you press the button for 3 3 seconds? Awesome. Why are you calm?
>> [applause] >> Nice.
So this is a weather monitoring uh we can easily track the what is the weather going on because the solar is totally dependent on the weather weather scenario.
We try to know what is the There is a our head office team which also backtracks the weather pattern and they tell our site team what will be the phenomenon. According to they adjust the load.
Uh currently we are here and this is the cloud section of the plant.
Okay sir, from 5 acres to 1 megawatt, now it has come down to 3.5. 3.5 acres to 1 megawatt. Oh wow.
Bifacial.
So 3 and 1/2 acres to 1 megawatt. 3 and 1/2 acres to 1 megawatt.
Quite similar.
Quite similar.
Actually a lot of people don't realize it. Actually that temperature plays after some level it really crashes.
Otherwise yes.
We have the two big power transformer 160 amp.
These are really [laughter] big. These are the big transformers.
160 amp and two transformers. The power is coming from the PGCIL power station.
First one.
And now 20 gigawatts challenge.
Next phase.
Now under construction at different phases is 20 gigawatts.
So giga.
Oh CM has promised the honorable Prime Minister 160 gigawatts.
So we are tracking that target.
160 gigawatts all together. Solar, wind, pump storage all together.
>> in the pump storage we do it.
These are the solar panels and the power gets accumulated in those SCBs and from there the these are the ICRs and the power gets accumulated in the ICR. From ICR goes to the MCR and from MCR it goes to the pool. Pool.
Additionally we have we have also done we put in robotic cleaning. Mhm.
Automatic cleaning of the panels.
>> [clears throat] >> Mhm. Which is much more efficient. Mhm.
Implement that thing or Implement that thing.
This is the glass. I see.
Wow.
And these are these are panels that you're making now?
>> Yeah, yeah. We are making them. You're making them. All in house. All in house.
So we are we'll be making cells also.
>> This is And uh Each panel Each panel is 640 W. It's probably the first panel in India we made.
happens with the tracker.
So the rotation unit is mounted on the end, no? Yes, yes, yes. Okay.
Got it. Congratulations, sir.
IPO comes out of here.
You ready? Ready?
So much equity will give the state government. What do you want? We we are giving lots of investment. I just calculated yesterday only.
It's comes to 27,000 crores. Yeah? In next We have completed by most of the investment by 28. Mhm.
Thank you.
>> And we will be completing that before July 28. Uh uh No, but I mean serious respect to you and your team. 11 months. These are record breaking. No, no. I never believed.
And it's crazy people here. We are going to be even faster. Even faster now now that you have understood. Yes, by I think March 28 we should be about 8 So that's That's on the solar side.
Based on the solar? Based on the And then you have your agri waste to energies, how many?
It's 165 megawatts. Right now? 200 is 200 are operational? 200 operational.
And then I think about 28 would be another 300 megawatts.
400 megawatts. Nice.
So actually even in the new vision document of the government of India Yeah. Now they've taken 16 gigawatts as a nation.
For agri waste? For agri waste.
Agri waste alone 16 gigawatts?
>> 16 gigawatts.
Actually China is already 35 gigawatts.
Europe is 31 gigawatts.
Also with agri waste the thing is revenue directly goes to the farmer.
>> I know. I know.
No, no. In fact I'm aware. I I read the note also. So I read the the proposal that has been submitted.
So that's the first part. Now and then and they don't burn the stubble. Yes. A lot of As earlier they were not believing. Recently I think two three teams from MNRE they visited one of our facilities and they have gone bonkers after that. Yeah? They have achieved [laughter] 90% PLF. And collection of we last year collected 2.6 million tons of paddy straw. Mhm.
2.6 million?
2.6 million.
>> [screaming] [cheering] >> Meeting meeting now.
Now I'm going to go now.
>> Namaskaram.
Namaskaram.
Namaskaram.
Namaskaram.
Namaskaram. Namaskaram.
Namaskaram.
