Dear DR....I just want to share something after watching your solar video..when I was in 8 th class, my father applied for a loan to buy a solar lamp because I belong to the Tribal area and a power cut is common. My father is a security personnel in APSRTC and the cost of solar lamp at that time is equal to his two months salary. He bought it for me and we i.e myself and sister used it for 4 years. Thank u brother for making such good videos. Even though kids are also waiting for your uploads. Thanks a lot.
