About Video :-
This video tells you how a Solar DC System works and what are the benefits of using this system in your house. This path breaking solar technology makes the system very efficient as there is no conversion of DC to AC. Solar electricity is generated in DC which goes to power DC fans, lights and TV. There is a battery for storage as well.
The Earth intercepts a lot of solar power: 173,000 terawatts. That’s 10,000 times more power than the planet’s population uses. So is it possible that one day the world could be completely reliant on solar energy.

solar panels me Solar heat se electron excited nahi hote photon se hote hai
agar aap bol rahe ho waise hota toh solar panels ko Aag pe rakhne se electricity paida ho jati 😂😂😂
I'm also electrical engineer, and you're 100% right
@@iamindian7989 yes yahi me bhi puchni chahi.......thermal ka concept h yr
@@iamindian7989
There is no difference between heat and sunlight in terms of their origin since both are forms of electromagnetic waves and have their own photons . But "Heat" or "Infrared radiation" has longer wavelength so less energy thats why it is not used.
Khan sir has students from different backgrounds (Art, Commerce etc) so he teaches in a way as lucid as possible. I hope you understood my point.
@@iamindian7989 hutiye....solar heat mey hi to protons hote hai

The benefit of lockdown is we get a teacher like you, who teaches in a lucid manner and in-depth analysis which is easy to understand for us. Thank you, sir
Western experts believe India’s goose is cooked since Modi unilaterally annexed disputed J&K the scenario is building-up where Modi will be forced to transfer sovereignty to foreign powers. Because of the lack of military logistics needed to fight the hi-tech War. There is a common fallacy among ordinary Indian people, who tend to think that the BJP government knows better. Mahatama Gandhi said the incorrigible Hindu elite looks at things from a wrong perspective, Modi tried his best in the process of saving the Indian capitalist economy, but destroyed the nation-state. In the mind of the deranged capitalist aficionados, capitalism importance supersedes the importance of the nation-state, The USA strategic policymakers had already calculated that China is unstoppable let's incite Modi to stand-up against China, and Modi fell for it and started giving eye looks to China, but China cognitively alert understands that without crushing Modi China risks hard-earned B&R hegemony. which America conceded it before inciting India.
