How does a Solar Cell work?

Hello everyone this is the first blog among the many technical articles on Solar that we plan to bring out. Hope you will enjoy reading them and find the information useful!   This article is all about solar cell’s functioning. Almost everyone who is in the solar industry would know this much: that a solar photovoltaic (PV) module converts sunlight into electricity. But do you know how it can do this conversion?   ———————————————————————————————————————————————————— The beauty of PV technology lies in the very nature of the universe – the way materials are made up of, the way energy interacts with it, and the way humans tailored the materials to result in this conversion. This blog tries to explain the basic physics behind the solar cell design even to an individual without a technical background.   Why should you bother with physics to understand how a solar cell works? Current means moving charges. A solar cell first has to produce charges and then make them move to generate current. So you have …

Excerpts from the 1000 MW AP Solar Pre-bid meeting

———————————————————————————————————————————————————————————– This is a follow up post to the article summarising the model Rfs document released by AP for procurement of 1000 MW of Solar Energy. You can view the original article here: ———————————————————————————————————————————————————————————— Location: Vidyut Soudha, Khairatabad, Hyderabad Duration of the meeting: Meeting was conducted in 3 batches with each lasting for 1-1.5 hours. No. of people attended: 500+ (Whoa!!)   Long day at APTRANSCO office today. Here are the updates of what happened at the pre-bid meeting. The meeting was poorly planned as, clearly, dividing the whole bunch of 500+ attendees into 3 different groups ticked off people who were waiting since morning but were asked to attend the 3rd batch of the meeting just because they were from Hyderabad (this included us). Preference was given to those who have come from outside of Hyderabad so that they can leave early owing to their plans to travel back. Finally, when the meeting (3rd batch) kicked off at 1:30 PM, APTRANSCO officials announced a few important points from the discussions …

Tamil Nadu Solar Energy Policy

Tamil Nadu is the pioneer state in Renewable Energy. With an installed capacity of 6970 MW representing 40% of the national total Wind Power and the second largest in Biomass with 488 MW installed capacity. It also has the largest number of accredited and registered RE projects. But in terms of Solar Power, TN has an installed grid-interactive capacity of 15 MW, a mere 1.5% of the nation’s 1044 MW. In this article, we try to present you a concise summary of the Tamil Nadu Solar Energy Policy – 2012 released on 20th October. The policy set the goals to generate 3000 MW of Solar Energy while achieving grid parity by 2015, which if realized will project Tamil Nadu as the Solar Hub of India. This state is one of the most highly suited places in the country for solar projects with a reasonably high insolation of 5.6-6 kW-h/sq. m and 300 clear sunny days in a year. Although still more expensive than other REs, Solar Energy is quoted as …
