As an Energy engineer I understand the road blocks of getting PV on EV cars. You did a wonderful explanation in this matter. There is another factor you need to consider 1. Energy received per sq meter on earth surface 2. Solar power conversion efficiency- now a days 30 plus is available, especially for this tasks. 3. Direct inbuilt solar panels options such as concentrated cell solar panels on top. 4. Increasing the Pv area on the bonnet. 5. Reducing the battery from EV car to reduce the weight and cost to accommodate PV system. 6. Additionak benefits such as reduction in heat inside the car. And so on I think as per your calculations u got 12 km 1kwh gives 10 km ideal condition and in real world around 6 km. Let's say 1000w per sq Mtr received on the pannel. So 2000W in total for 2mtr sq, I am only considering 2 mtrsq roof area. Conversion efficiency 25 percent. Capacity of the pannels 400w per sq mtr thats 800watts 2000 watts 30 percent conversion efficiency that will give 600W per hr You may charge for 5 hrs a day with full efficiency 5hrs * 600 = 3000wh that is 3kwh giving ideal range of 30km and in real world above 15 km. And this is just start, you may use the bonnet area also. You may get above 40 percent efficient panels. I agree that adding a pv pannel on top of a car isnot that great idea until it is in build to the roof. Every year the efficiency of the pannel are getting increased and with lots of graduates and researchers working on this problem. I am sure soon enough there will be pannels in market with 50 percent efficiency and and above. Very recently there was a discovery which can potentially increase the yield from sund 1000times. I hope I have shared useful information here.
On first note, I appreciate your efforts put on this thesis. And appreciate to share your knowledge to others. You are awesome. Though the result is negative but it has answered my questions aptly. Well done.
Good study. But wish to highlight, the failure of battery vehicle is not charging batteries in time. Even though the solar charging is very smaller in quantity , but on the long term the battery life is enhanced for sure. So adding solar is technically advantages in my opinion.
I will take a tape and measure length and breadth and then calculate area of roof instead of getting graph paper and calculating. I appreciate your efforts.
@@knowledgeresurrection7873 Again I appreciate your efforts. Particularly for your conclusion. Having solar cells on car roof doesn't help for increasing range of car for any practical usage.
Brother I have a suggestion. (If we mount alternaters underneath EV body some where on the chassis with gears to rotate along with wheel momentum, won't it be possible that it will charge the battery while on the go?) Please do some research on it aswell.
I have a nexon ev xm model I have purchased a Duramax 15000w portable generator with it I keep it in my boot( it is compact and movable) It gives an output of 15000max watts and around 13000 running watts. It has 6outlets, 2x15amps 120v 2x30amps 120v switchable to240v 1x50amp 120v and 1x50amp 240v It charge my car anywhere in 20mins ... Takes 1.5lts of diesel per hour 😀 So fr rs170(approx) i can charge my nexon anywhere in India 3times 😀 And in rs170 i can run around 750kms So its 0.2p per km
@@rudrakshsaha5936 , please help me with price. I will try to find it offline and make some negotiation. DO you suggest any alternative generators too, in case of I don't find it. Thanks for your prompt reply. Also, pls don't mind in giving me some gyan, so that I will find it myself. What power output should I consider before buying the portable generator. Any portable earthing arrangements shuld be done for this? Also, as he said in the video, even though if you go with 50kW fast charger, car can only take 25kW. In that case how is your car able to charge in 20min.
Tata and other companies r using converter from dc to ac three phase the power generated by other means is it posible to feed in to the inlet of converter can u help here
Hats off brother.... great explanation about solar system with evident. It’s highly appreciable . I feel like sitting in class room. Great job. Keep it up bro....
thanks for the excellent video regarding the subject. what about a different scenario, imagine the car is driven to and back from work which is a total of 10 km and the car is parked where its very sunny without any shade from sun rise to sun set. if i had a solar panel installed wouldn't it keep my battery charged throughout the day at 100%, since the car is exposed to sunlight almost all throughout the day for the entire week
Well you can give it a try. Few points though. 1) Manufacturing company will void your vehicle warranty. 2) You will be driving the ugliest looking EV around. 3rd and finally aerodynamics will get affected surely resulting in low battery efficiency. My advice is to get a home rooftop solar panels system (11 kva) if possible. Enjoy your life time free fuel and for upcoming generations.
How v can transfer voltage produced from solar panel to ev car battery since v r producing dc current and perticular voltage do v need to sinchronise the transfer system
Hello sir. Thanks for watching. Yes sir, we can distribute the weight by small panels but we will get a slightly better W/m2 while installing just one bigger panel because we will have more solar cells and less framing. Also installing many small panels will require more electrical connections which will increase losses and the system will be less reliable. And it will take less effort to just install one big one instead of many small. But if someone wants to, yes surely they can go with small panels.
hello, i loved your video. what if you install the PV system on an electric van like Mercedes Benz eVito and then use the PV system as an auxiliary battery to reduce the load on the main battery to give it more distance?
Thank you. You answered my questions with calculations, it's amazing. I appreciate your efforts in bringing this video, hope you keep doing these interesting videos.
You can increase the surface area by installing foldable hinges, so you can unfold the panes on all the sides including center. Theoretically a person charging ev on solar would obviously not be driving but in parking state. So the person can install more panels with a mechanism that can be unfolded at an angle to avoid inconvenience while parking in open. Please do an update on this theory as well.
Awesome work buddy, really appreciate the efforts you put into this.. I was having this question in my mind for long, now you answered.....I have another question, if possible can please you answer .......can we charge while on move with installing number of Micro Motor Wind Turbine Generator
Brother, Your effort to make a case study is commendable. But,it is not at all practical to install them on top of car,due to its additional weight which further reduces mileage of car; solar panels required a particular inclination/direction (angle),also it should be still to abosrb the maximum sunlight; Hence, practical solution is to install an Array of solar panels based on the EV battery capacity on the Roof top of House,along with PV Inverter connected, to Grid(optional) with a storage battery-to store solar energy throughout the day. Later,in the evening/night the stored energy will be used to give back-up (for charging the EV) i.e,to Car. Optional:If you are not using the car(incase during daytime, let's say for few hours or so) it can directly charge the EV,too. Of course,the intial cost of installing the Solar panels,it's components, wiring etc.,will be high,but,it will give GOOD RETURNS in Long Run. The Life of the quality Solar panel assembly is around 25 years,if maintained, properly. Just,imagine the amount of Petrol/Diesel (fuel saved) in such a SPAN. GREAT👌👍
Wow bro. You just summarized my next video of 28 mins😄. But still do watch it if you can spare some time. Link - th-cam.com/video/xyd9HrIJf9E/w-d-xo.html
Great efforts sir. But its still impractical in all aspects. If this concept was possible before, definitely the EV giant Tesla may have been experimented this idea before. There is only one better thing that we can do by the time being is, install a minimum 5 KW capacity of Grid Tied (On Grid) solar system at home to completely rid off from running cost until the DC fast charging facilities are available across the country.
Exactly. You completely understood the point which I was trying to make. Next video will be on Grid-tied system only. Stay tuned and thanks for watching✌✌
@@knowledgeresurrection7873 - You are most welcome Sir. Also If possible, while experimenting on Solar system, please make a feasibility study on whether we can do DC charging the electric vehicle directly from Solar panels through a charge controller or that must be from a battery back-up?

Hz. etc. If so, then we can avoid using the DC to AC inverter. All we have to make sure the constant Ampere current flow during charging time The subject is quite interesting and I have been searching for this project since long time. Thank you.
Hello sir. First of all thanks for watching. Sir its actually very difficult to give a general or universal answer to your question because there are a lot of parameters to consider. But i will try to explain it in best possible way - As you can see in my calculations I have calculated the maximum possible theoretical range that you can add is 12 kms per day in which I have assumed that your panels are receiving 4 hours of sunlight per day at a constant solar irradiance of 800 W/m2 in which i have not included any real world conditions. So 12 kms per day is the max. possible range that you can add per day. Now even if you park your car in sunlight all day and suppose you managed to get a sunlight for 5-6 hours (10 am to 4 pm) but you will not get a constant solar irradiance of 800 W/m2 for complete 5-6 hours. In simple terms, the the sunlight will not be strong for whole day, as we know that at 12 noon the sunlight is strongest but during mornings and evening it is not that intense, but in my calculations i have assumed that we are receiving the strongest sunlight (solar irradiance = 800 W/m2) for complete 4 hours. So even we park in sun the max. possible theoretical range that we can add will be around 12kms per day only. Now again if we add the real world parameters into consideration which i have mentioned in my video, it is very difficult to quantify every parameter (possible but very difficult calculations) and calculate the exact real world range addition. But to answer your question even if we park in sun and take other real world parameters into consideration, the range that we will be able to add will not exceed 6-7 kms per day ( this is my approximation as its very difficult to calculate exact figure ). Now will it be a good idea? So according to me that is relative. Some people might be happy to get an additional 6-7 kms of range, some might not because we have to put some effort also in installing this setup. Personally I feel that it is a good idea if you think about it as a project and in terms of learning but economically I will not prefer this rather I will install a solar pv system at my home rooftop and charge my ev with that.
Hi sir, First of all I very much thankful for you for providing these vdos. Q1. Can v get good output by install asolar panel on front side of tata nexon ev. Q2. How much solar panels require for charging nexon ev Outside when battery over. Q3. Can v charge using solar panel while running ev car. Is there any loss of battery.
Hello sir. Thanks for watching and asking such interesting question. Ok let me give you a brief analysis - So suppose we want to generate electricity with wind power, then we have a install a small wind turbine somewhere on the car. So according to me we can install it either on the roof or at the front. Now when the car is moving the air will strike the turbine and can generate electricity which we can supply to the battery. Now lets calculate how much electricity we can generate. So for that first we have to decide the size of the rotor blades of the turbine. So considering the size of nexon ev, I think we will be able to fit a rotor blade of maximum radius of about 40 cm at the top or front. (Even this is large but lets Calculate the max. possible value) Now suppose you are driving on an average speed of 30 km/hr or 8.33 m/s. So if we calculate the power output (P) by the turbine - P = pi/2 × (radius of turbine)^2 x (velocity of air)^3 x (density of air) x (efficiency) P = 3.14/2 x 0.4^2 x 8.33^3 x 1.2 x 0.4 (efficiency is around 40% for the system)= 0.07 kW Now suppose you drive about 4 hours per day So the total electricity you can generate per day from wind = 0.07 kW x 4 hours = 0.28 kWh Now lets see how much range this will add - As we know for tata nexon ev, we can get 250 km from 30.2 kWh of battery So 0.545 kWh will add - (250/30.2) x 0.28 = 2.3 km of range per day. But, this installation of wind turbine at top or front is gonna increase the overall weight of the car and aerodynamic drag so drastically that it will put a huge load on ev battery and it will drain very fast, so instead of adding 2.3 kms of range per day the range might even decrease after Installing the wind turbine. And thats why powering through wind is not a feasible and practical solution.
@@knowledgeresurrection7873 I agree, but there must be a solution to this. I watched another topic which was followed from this video. Solar at home. I am bit confused because I am about to install 2kw solar to my home on-grid. But also I need a backup when power goes down. Is it possible to have a battery which acts as a UPS when power goes down? If yes, how can it be? Whether worthy or not?
Okk. I understand your requirements. I will suggest you hybrid solar rooftop pv system. With this you can generate electricity and can run your home appliances and at the same time charge your batteries also, so when power is cut you can use your batteries. The hybrid inverter will be programmed and it can decide which supply (direct from solar panels or batteries) to use and when to use. Also if you generate excess electricity you can send it to grid. It will cost between 1.5 to 2 lakhs for 2 kW system. And it can be worthy if there is frequent power cut at your home so that you can use batteries. Otherwise on grid is the most economical one.
..and that's why my friend, the car makers are not putting solar panels on the roof. Also, there is a risk of theft if you just put panel yourself on the roof.
1.4 KWH is not correct, with proper arrangement of cells, you can get about 700 W from panels max. Even if the direction is not correct or panels in shade, the power output is not zero. If the car is parked for most of the time, I guess you can about 4KWH max in about 8 hours (Typical Office timing). In city traffic, since you are not driving at higher speeds, I believe Wh/Km demand would be around 70-80 Wh/km and this would give additional range of about 50 Km. Enough to manage to & from office within 25 Km reach of home.
How about transparent solar stickers? That will solve the problem of weight and aerodynamics issues. Transparent stickers can be pasted in all possible places and not restricted to roof alone!! Pls suggest the drawbacks on this!
Bhai sorry for late reply. I could have said in one line but then no one cares unless you prove it.😄. Hence the calculations. Dont worry I will try to keep it short and precise from next time.
Practically it’s not possible , 1st there should be a system to resolve heat solar power will increase heat in car , Damage to plastic quality , if We use alternative also not budget friendly , if it was simple the market leader of EV would have showcase it ,
Cars sit 95 % of time in parking lot .........average distance to work is 20 km in Indian cities so with increased solar efficiency and battery efficiency a 30 km per day range will lead to decrease in car battery requirement ...leading to decrease in car weight ...leading to increase in efficiency ....this positive feedback loop will soon make solar a viable option in counties liike India where sun is plenty and driving distance is not much
Yes sir. Considering the pace of development in battery technologies as well as advanced solar panels, in coming future we might be able to see solar powered cars in day to day life.

As an Energy engineer I understand the road blocks of getting PV on EV cars. You did a wonderful explanation in this matter.

1. Energy received per sq meter on earth surface
2. Solar power conversion efficiency- now a days 30 plus is available, especially for this tasks.
3. Direct inbuilt solar panels options such as concentrated cell solar panels on top.
4. Increasing the Pv area on the bonnet.
5. Reducing the battery from EV car to reduce the weight and cost to accommodate PV system.
6. Additionak benefits such as reduction in heat inside the car.
And so on
I think as per your calculations u got 12 km
1kwh gives 10 km ideal condition and in real world around 6 km.
Let's say 1000w per sq Mtr received on the pannel. So 2000W in total for 2mtr sq, I am only considering 2 mtrsq roof area.
Conversion efficiency 25 percent.
Capacity of the pannels 400w per sq mtr thats 800watts
2000 watts 30 percent conversion efficiency that will give 600W per hr
You may charge for 5 hrs a day with full efficiency
5hrs * 600 = 3000wh that is 3kwh giving ideal range of 30km and in real world above 15 km.
And this is just start, you may use the bonnet area also. You may get above 40 percent efficient panels.
I agree that adding a pv pannel on top of a car isnot that great idea until it is in build to the roof.
Every year the efficiency of the pannel are getting increased and with lots of graduates and researchers working on this problem. I am sure soon enough there will be pannels in market with 50 percent efficiency and and above.
Very recently there was a discovery which can potentially increase the yield from sund 1000times.

In simple terms, the the sunlight will not be strong for whole day, as we know that at 12 noon the sunlight is strongest but during mornings and evening it is not that intense, but in my calculations i have assumed that we are receiving the strongest sunlight (solar irradiance = 800 W/m2) for complete 4 hours. So even we park in sun the max. possible theoretical range that we can add will be around 12kms per day only.
Now again if we add the real world parameters into consideration which i have mentioned in my video, it is very difficult to quantify every parameter (possible but very difficult calculations) and calculate the exact real world range addition.
But to answer your question even if we park in sun and take other real world parameters into consideration, the range that we will be able to add will not exceed 6-7 kms per day ( this is my approximation as its very difficult to calculate exact figure ). Now will it be a good idea? So according to me that is relative. Some people might be happy to get an additional 6-7 kms of range, some might not because we have to put some effort also in installing this setup.
Personally I feel that it is a good idea if you think about it as a project and in terms of learning but economically I will not prefer this rather I will install a solar pv system at my home rooftop and charge my ev with that.
Hi sir,
First of all I very much thankful for you for providing these vdos.
Q1. Can v get good output by install asolar panel on front side of tata nexon ev.
Q2. How much solar panels require for charging nexon ev
Outside when battery over.
Q3. Can v charge using solar panel while running ev car. Is there any loss of battery.
nice one 🤙
Very well explained.! Dude..🙂👍 can you make video on regenerative braking and it's feasibility ?
Sure Bro✌. Just give me some time.
When will you bring the roof top solar for home and EV
Tomorrow for sure. Thanks for watching and stay tuned.✌✌
I have published it. You can watch it whenever time permits. Link - th-cam.com/video/xyd9HrIJf9E/w-d-xo.html
Amazing
Great 👍
Is it possible to get electricity instead of solar rather than air? Let's say wind power?
Hello sir. Thanks for watching and asking such interesting question. Ok let me give you a brief analysis -
So suppose we want to generate electricity with wind power, then we have a install a small wind turbine somewhere on the car. So according to me we can install it either on the roof or at the front. Now when the car is moving the air will strike the turbine and can generate electricity which we can supply to the battery.
Now lets calculate how much electricity we can generate. So for that first we have to decide the size of the rotor blades of the turbine. So considering the size of nexon ev, I think we will be able to fit a rotor blade of maximum radius of about 40 cm at the top or front. (Even this is large but lets Calculate the max. possible value)
Now suppose you are driving on an average speed of 30 km/hr or 8.33 m/s.
So if we calculate the power output (P) by the turbine -
P = pi/2 × (radius of turbine)^2 x (velocity of air)^3 x (density of air) x (efficiency)
P = 3.14/2 x 0.4^2 x 8.33^3 x 1.2 x 0.4 (efficiency is around 40% for the system)= 0.07 kW
Now suppose you drive about 4 hours per day
So the total electricity you can generate per day from wind = 0.07 kW x 4 hours = 0.28 kWh
Now lets see how much range this will add -
As we know for tata nexon ev, we can get 250 km from 30.2 kWh of battery
So 0.545 kWh will add - (250/30.2) x 0.28 = 2.3 km of range per day.
But, this installation of wind turbine at top or front is gonna increase the overall weight of the car and aerodynamic drag so drastically that it will put a huge load on ev battery and it will drain very fast, so instead of adding 2.3 kms of range per day the range might even decrease after Installing the wind turbine.
And thats why powering through wind is not a feasible and practical solution.
@@knowledgeresurrection7873 I agree, but there must be a solution to this. I watched another topic which was followed from this video. Solar at home. I am bit confused because I am about to install 2kw solar to my home on-grid. But also I need a backup when power goes down. Is it possible to have a battery which acts as a UPS when power goes down? If yes, how can it be? Whether worthy or not?
Okk. I understand your requirements. I will suggest you hybrid solar rooftop pv system. With this you can generate electricity and can run your home appliances and at the same time charge your batteries also, so when power is cut you can use your batteries.
The hybrid inverter will be programmed and it can decide which supply (direct from solar panels or batteries) to use and when to use. Also if you generate excess electricity you can send it to grid. It will cost between 1.5 to 2 lakhs for 2 kW system.
And it can be worthy if there is frequent power cut at your home so that you can use batteries. Otherwise on grid is the most economical one.
..and that's why my friend, the car makers are not putting solar panels on the roof. Also, there is a risk of theft if you just put panel yourself on the roof.
Right
Wow..
1.4 KWH is not correct, with proper arrangement of cells, you can get about 700 W from panels max. Even if the direction is not correct or panels in shade, the power output is not zero. If the car is parked for most of the time, I guess you can about 4KWH max in about 8 hours (Typical Office timing). In city traffic, since you are not driving at higher speeds, I believe Wh/Km demand would be around 70-80 Wh/km and this would give additional range of about 50 Km. Enough to manage to & from office within 25 Km reach of home.
Bro , how to put our in the Graph, is there any software? anybody know?
Hii. Yeah its very easy, I just used photoshop.
Brother i can you do this practical. Demo
How about transparent solar stickers? That will solve the problem of weight and aerodynamics issues.
Transparent stickers can be pasted in all possible places and not restricted to roof alone!!
Pls suggest the drawbacks on this!
Okay....
There is some thing called Tape Measure!
Take it and measure the roof area!!
wow! nice idea. JK. The only problem's that I was not having any NEXON EV around me at that time. # POOR🙃
Everything is "right". Just please replace the "right" s in your audio with silence. Will be awesome.
Right😆. I will try to make it Right. JK😃. Thanks for watching. It will be less annoying next time.
@@knowledgeresurrection7873 😂😂
I have a doubt. Bro
Bhai....sidhe sidhe sirf 12km/din mein 5 ghante sooraj ki roshni degi bolne ko nahi hota hai kya?
Bhai sorry for late reply. I could have said in one line but then no one cares unless you prove it.😄. Hence the calculations. Dont worry I will try to keep it short and precise from next time.
Practically it’s not possible , 1st there should be a system to resolve heat solar power will increase heat in car , Damage to plastic quality , if We use alternative also not budget friendly , if it was simple the market leader of EV would have showcase it ,
Cars sit 95 % of time in parking lot .........average distance to work is 20 km in Indian cities so with increased solar efficiency and battery efficiency a 30 km per day range will lead to decrease in car battery requirement ...leading to decrease in car weight ...leading to increase in efficiency ....this positive feedback loop will soon make solar a viable option in counties liike India where sun is plenty and driving distance is not much
Yes sir. Considering the pace of development in battery technologies as well as advanced solar panels, in coming future we might be able to see solar powered cars in day to day life.
@@knowledgeresurrection7873 great work man , pls drop the British gulam dari Sir and rest is fine

Instead of solar cells you can just get a 2nd hand generator of small size and recharge your car anywhere
