- Solar Panels Efficiency Crisis: Can We Solve It? In this video, we dive deep into the challenges faced by solar panels in India, where extreme summer temperatures can cause a significant drop in efficiency. We explore the initiatives taken by the Indian government to promote solar energy through solar parks and rooftop systems. However, with temperatures soaring up to 50 degrees Celsius, the efficiency of solar panels can decrease by up to 50%. We'll discuss the innovative cooling technologies being developed globally, including water, gas, and air-based systems, and their potential to mitigate these issues. Additionally, we'll review research findings that show operating solar panels at 25 degrees Celsius can dramatically improve their efficacy and lifespan. Join us as we analyze the limitations of current systems and the future improvements needed to sustain India's solar energy growth.

1Coir mattresses From below and spray water that will evaporate and cool down
. 2.Solar ke Neeche water rakho ki evaporate hone per Thanda ho jaaye
3.Sprinkling water with car type radiator cooling heat exchange system with recycling same water throughout day
4 . enclosing with a.c.p jacket and circulating air from one side and removing From next side increasing fresh air allowing cooling panels
5.water tank circulating copper/aluminium pipe heating water and cooling panel
6.Putting double glass sandwich panel to increase conduction increasing heat decipation
7 putting radiator with fan below panels with coolant to decipate heat with temp cutoff device thermostats
8 Putting vertical bi facial glass sandwich panels to pass hot air Faster vertically resulting faster cooling and higher reflecting sunlight to each other increasing panels efficacy .also lower dust accumulation
Nice suggestion we might try some 👍
@@lumencity any help required let me know
@@The16june76 water is still wasted.
Why not convert it to steam and use it for driving generator Or 540kcsl into a heat pump!!!!
Pani se thanda karna he kyu hai jaise car ki coolant aati hai waise he ek coolant banna chahiye
What cost
Water circulation pipe at the back is the best solution. Its problem of heat accumulation at one side can be completely eliminated by properly designing the heat exchanger and eventually the direction of water flow.
Isme there are issues 1) to design the system for even cooling
2) Plumbing and water leaking issue
3) costing issue
4) water freezing in winters
5) Running a water pump additional cost
we need to think better alternatives 🤔
Y not install a thermometer based automated mist/fogging system like in polyhouse farming, such that temperature never rises above a certain degree and do not develop microcracks of glass. Will it be feasible?
2 way pipeing kar skte hai yani both side inlet and both side outlet kare water ko ...jisse sare cell ka temp ek jaisa hoga
Mara phone ma bhe liquid cooling ha tao ya panal ma bhe ho sakti ha
Green paldh lagwa sakte he
Rectangular pipe channel (to increase surface contact instead of round pipe) touching the back of panels, 12V cooler motor for minimal electric consumption and a honeycomb mesh like that of cooler with 12v fan can be used. Cost will be quite less and no water leakage as pipes can be pre made coz panel size is almost same for all. Inlet and outlet points can be joined in series with other panel by plastic pipes available (the same pipes used to measure surface level during construction work).
The system can be switched on around 11am when temperature starts rising and switched off nearly 4pm. As the water will take atleast 15-20 minutes to start cooling just like room cooler, but we dont need that big of a fan, just a fan big enough for honeycomb portion for evaporative cooling.
Temperature ko normal rakhna ek badi problem h kyuki hum gharo ko cool rakhne ke liye bhi sustainable solutions nahi khoj paye h Jo cost effective or environmental friendly bhi ho.
Esliye solar cell par hi research karni chahiye thaki Aisa solar cell banaya ja sake jo jayada temperature par bhi efficient tarike se kam kar sake.
Mere hisab se ye direction research ke liye thik rahega.
Cooling solution hamne khoj bhi liya to usko cost effective banana muskil hoga.
True
Exactly

First and foremost is the cost of cooling worth the gains in efficiency.
Radiator cooling system kar sakte hain jesa car ka radiator hota hai
2:09 need the paper link
Solar panels are made to withstand rains. Water sprinklers won't harm them. Bigger problem is cleaning circulating water. A 15 watt pump can boost performance of a 4kw system at least 15 percent in India. That's free money, while extending life of solar panels. Water usage will be around 5 litre per hour.
Great advise
What wavelength is used to make electricity? If its not in visible spectrum then we can shade solar panels with materials which can filter unnecessary wavelength. Feedback on this thought is appreciated.
No actually its visible spectrum
Bhai Jabardast information
👍☺️
Can heat reflective coating be applied on frame?
Yes It could be an Option
Simple solution ha, panel ko different sides Sy cold water inlet lagao , all cells k temperature same rhy ga
Meta material developed by Sky cool should be integrated within PV panel for even distribution of cooling.
Cooling fan or cooling liquid at backside like in laptops etc will definitely emit heat out
I have an idea to use air curtain over the panels top surface and planting beneath the structure to minimize surface heat of pv panels would it works ???
Air Curtains consume lot of Energy Don’t Think it would be a good idea to
@@lumencity a DC fan which consumes around 50w DC with mist fogger rotating and throwing the cool misty air on the panels ??
@@lumencity I think any type of cooling idea takes some energy but it increases the lifespan of panels and slow yearly degradation and somehow cooling down the panels gives a little more energy than cooling system consumes..
solar panel glass made with few matles that keep the glass cool simple ..
Tec12706 nomber ki ek plate ati hai vo laga sakte hai solar ke back side me isme plate ko voltage dete hai to ek side cold or ek side hot hota hai so cold side to solar k piche atech krke plate ko thnda rakha ja sakta hai or plate ko chala ne ke liye Jo voltage penal ka drop ho Raha hai uska use kr sakte hai yani free me solar ko cold rakha ja sakta hai
yes there are thermo electric peltier we can try those and see the results, Thank You for suggesting 👍
Peltier module is good for small scale utilisation, for large scale the voltage required to run the module will surpass the electricity generated by panel. Not economical for large scale.
The solar panels are installed facing south. If water tanks are positioned one floor higher on the north side of the homes, the water supply can be arranged to flow from the tanks, pass behind the solar panels to cool them, and then be used for household purposes. Since the water supply is abundant, it will not become excessively hot while passing through the system, ensuring that the last panels in the sequence also receive effective cooling. This cooling method is expected to enhance the efficiency of the solar panels.
Duckting of heatsink material duckting pipe k shuru ke siry ma aik cpu high speed fan ho (for sucking) or ending pe bhi aik ho (through krny ke liey)
Or sath hi solar panel ma kuch cells barha k 12 volt ki aik series alag se nikal den ta k wo apni electricity khud e banay cooling k liey
Kiun ke piping wala mehenga ho jana kam or maintenance coolent ya pani dalny ki pareshani......
krni pary gi or roz ki chik chik .....
Ducting itni mehengi nahi ho gi or one time kam ha jo company se ho k ay khud se na kren panel design hi ese hony chahiey heat ka naam o nishan ni ho ga ❤
Do u provide services in Kolkata?
Yes But only for commercial projects above 20KW
WHAT IF WE MAKE A SHADE ON PANELS TO PROTECT FROM DIRECT SUNLIGHT
😂😂😂😂😂😂😂
Why not consider somethihh like a refrigerator?
A reflector sheet that reflect all the unnecessary spectrum and only utlize the particular spectrum
Just use passive heat sink.
For even better efficiency, use a vapour chamber.
Heat sinks for the size of solar panels will be very expensive and would Impact the Already high upfront cost of solar system plus its not scalable to MW level
Solar panel ke pichhe peltier module laga de toh...
Yes it can be done 👍 But its expensive
opposite direction flowing water could cool panel comparatively evenly
but that would not cool the center evenly
Aluminium heatsink lagou jisase heat even circulate karenga bad me back me use water pipe se cool Karo ya air cooler wale air se
Yes It Could be an Option Thank you for quick response
I think buying more pannels is better than cooling those with expensive machineries like u suggested, the copper pipes, pump all these will cost higher then adding more pannels if you have space and having a garden underneath.
East West facing solar panel can easily reduce temperature during hottest noon day time
Jesa ki mai dekh pa rha hu sbhi vidwano ne apna apna bahumulya suggestion de rakha, behtar issey kuch achha soch kar bataunga😂
Bdw- can’t we simply blow cool air on panels from a certain distance through coolers(with horizontal swing), obviously it can be implemented on small systems like 3-5 KW. 😊
if solar panel are installed at a height of 6ft so normally the wind flow do that work,
Bhai cooling ka cost kya efficiency badhane se kum hey tab to is ka fayda hey .Nahi to time waste hey
Bhai green net 🥅 lo aor 5 feet upar fit kr do
Why not we flow liquid nitrogen in pipes
we have to keep costing under control
The Cryogenic Temperature of Nitrogen is very low (-196 Degrees C) and to turn into liquid it also has to be repeatedly compressed & cooled requiring some heavy compressors. Cryogenic means liquification at at very low temperature and at very high pressure
Paltier module laga skte hai panel ke neeche aur 2nd side heat sink laga kar paneel ki heat ko electricity mei badla jaa skta hai jisse mota moti 50 to 70% extra electricty banegi aur 30% panel ki eficiancy badh jayegi.. koi funding kare toh mai kar ke dikha sakta hu ..
Bro ise se solar panel ki price 5-10 Guna badh jaya gi aapka yeah idea physics ke hisab se sahi hai per economics ke hisab se galat hai
Ek removable glass panel jo sirf particular spectrum ko enter hone de to 25° per lock ho jayega temperature
Yes But such a panel would increase the temp of the panel if insulation is not kept in between 👍 But its a great suggestion
Infra red rays ko hi allow karne wali so,aur panel per research ho raha hey . Agar woh ka yaa ho jata hey to yeh problem hi nahi rahegi
Dimak ghode ko thoda kam ma lagao jissa asa Glass banay ja sakhta ha jinsa sun sa ana Bala 60% unusefull light ko block Kia ja sakha .
Jissa o extra light panel par nahi ayega and overall panel thanda rahega, eya Idea agar Kam kar Gaya mujha 50% partnership chiya
Solar penal per senser laga do particuler temperacer se uper jaye gs to penal ka direction change kar de
Solar panels ka structure heavy hota hai structure ko move karne ke liye heavy motor ka use karna padta hai, isse temp me zyada difference nai ayega but system ki maintenance and initial costing zyada badh jayegi
Thermal paste lagado panel ke pichhe
Ek kam kartahu ak alag sai ac install kardeta hu
Heat sinks should be provided with PV

solar panels k niche kamra banao aur chiller ac laga do jo khud ba khud on ho jain jab heat aani shuru ho jaye aur silver ki chadar daal ko panels k bilkul niche chadar heat sink ka kaam kare gi aur ac us ko thanda karne ka
efficiency Improve karne ke liye humare ko kam se kam electricity use karni hai
Sun light se jo heat spectrum aa rha hai reject karne bala flim ko solar panel per laga diya jay ..
Maat karo bhai success nahe hai
yes but there will be challenges 1) how to develop such film and then 2) challenges is how to keep distance between the film and cell otherwise the film will get hot and it would make the solar panel hot
One more good reason to avoid solar. Atleast for now....⭐⭐⭐
Even after being inefficient in extreme Heat 🥵 They are still efficient in saving you lots of Money
As usual no proper solution bus idhar udhar ki Baat kar rahe ho
Aur end me ancient log burf kaise banate te the
Bus ye hi baki tha
Yes We have Not Given Solutions as There is none we have covered all the research in this field and left the viewers to discover what can be done for this problem
I have a solution, we can use a filter which will be placed 2-3 feet above solar panel and allow the specific spectrum of light to pass through and block other light which produces heat
