With the world advancing towards automation and innumerable devices making our lives progressively comfortable, the threats posed to our mother nature are being not accounted for. One of the eco friendly tasks that an individual can easily go for is to opt for solar power. There are many places where we receive plenty of sunlight, [...]
A hundred and fifty million kilometers away from earth, being a nearly perfect sphere of hot plasma, sun emits around 3.86×1026 watts of energy. But only 1.74×1017 watts of energy is received by earth with the world’s yearly consumption being around 1.8×1013 watts. Harnessing this amount of energy from sun would save the earth [...]
 Many a times when a customer tries to go for a solar installation, he asks about panels and their types and their respective lifespans. Generally, panels are manufactured using polycrystalline cells. But every time a question arises regarding thin film solar cells which are light weight and cheap. Then why aren’t we using these [...]
Not the usual day it was. Very lovely weather. Mesmerizing for people working in Sun. We started to our site having hot tasty breakfast of our choice. We started with an enthusiasm that we will finish installation of 1000 panels crossing 300 kW on the project we are working. Started at our usual time 8:45 [...]
The Central Power Research Institute is an autonomous society under the Ministry of Power, Govt. of India. In their Fan Testing Laboratory, ELECTRIC CEILING FANs are tested as per IS: 374 -1979 specification. This is published by the BUREAU OF INDIAN STANDARDS which is The National Standards Body of India. Air Delivery Test at CPRI Here is [...]
A superficial cost comparison may mislead a fan buyer into thinking that ordinary fans are cheaper than SuperFans. A quick product price comparison shows that ordinary induction motor ceiling fans range in price from Rs 1250 to Rs 1700, and the energy saving Havells ES 50 costs about Rs. 1700, inclusive of regulators. To justify [...]
Thinking like an environmentalist and as a solar evangelist, I would prefer India to reduce its dependency on coal drastically and switch over to SUN immediately to combat Climate Change. Here is the Dilemma!  As a socio-economic activist, we I prefer to accelerate it’s Development, by any energy means, of all of its 300 Million [...]
Solar and Wind energy sources  had two main issues. They were expensive and were not immediately dispatchable. But at utility scale they are not expensive any more. Internationally, in Texas, U.S,  Austin Energy, a solar developer, has agreed to supply the power from their solar farm at 5 cents a kilo-watt hour. That's Rs 3.11 [...]

It’s a common misconception that the solar panels generate more energy with higher temperatures and less energy with lower temperatures. So the assumption is that we have more power generated in places like Chennai than in Bangalore or for that matter in Himachal Pradesh. But in reality,  solar cells, like in all semiconductors  are [...]
