TechBlog3: Why are PV efficiencies so low?

After a bit of a delay, we bring forth the third technical blog for you to learn the science behind solar power. This blog talks about PV solar modules efficiencies and addresses why nature limits them to such low numbers and how scientists are trying to overcome these limitations.   It would probably not have escaped your notice that the efficiencies of the solar PV modules are quite low. You usually see transformers and inverters, other electrical equipments used in solar plants have efficiencies above 95%. And yet, the PV panels have efficiencies < 20%.The most commonly used PV technology, crystalline-Si, has best commercial efficiencies 16-19%. The emerging thin film technologies give at best 12% (CdTe thinfilms). So, almost 80-90% of the energy in the sunlight is not being utilized by the solar cells. Why? And where is this wasted energy going? Read further to find answers to these questions.   Efficiencies are limited by the very nature of energy conversion in solar cells. What does a solar cell do? …

Punjab releases an RfP for 300 MW – New grid-connected PV plants – Bids Due on 25 Apr 2013

This week has already seen the Karnataka government’s KREDL release a Request for Proposal for 130 MW solar thermal/PV (photovoltaic) development. Now the state of Punjab has also released an RfP document for Phase I of its total target of 1000 MW of solar generation capacity (as per its NRSE policy 2012).   This RfP calls for newly grid connected solar PV projects with an aggregated total capacity of 300 MW for direct sale of power to PSPCL (Punjab State Power Corporation). The selection of bidders will be through tariff based competitive e-bidding process.   NRSE’s benefits that the developers could avail are: -          Waver of electricity duty -          Exemption from Octroi on NRSE fuels and self-consumption by captive power plants -          Exemption from VAT on the machinery/equipment and devices/systems. -          Waver of entry tax -          Waver of stamp duty on land agreement registrations -          No change of land use charges, inclusion of agricultural land as usable -          No requirement to obtain NOC from PPCB   Portfolio of PV projects: The aggregate …

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 …

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 …

Developers try to protect Solar Power businesses against Anti-Dumping duty

(Source: The Hindu – Business Line) Solar power developers in the country have united to devise a strategy to counter any anti-dumping duty on solar cells and panels imported from China and the US. (Anti-dumping investigations were notified by the Ministry of Commerce on November 28.) With only 40 days to submit a reply, 12 solar power developers participated in a conference call on Friday to discuss means to thwart any anti-dumping duty. Developers decided to activate the dormant Solar Independent Power Producers’ Association, for effective lobbying. They will also hire a consultant to generate data to back the Association’s case, and a law firm to argue the case. Read more..

Andhra Pradesh Solar Power Policy: Amendments and Clarifications

Ms. No.39. The following are the amendments as per the order: State will promote Solar Power developers to setup Solar Power plants for captive use or sale of power to 3rd party/State within the state only. V.A.T refund will be done for payments made in the state of Andhra Pradesh only. Irrespective of voltage level, Open Access Clearance shall be provided to both generator and consumer for 25 years or life of the project (whichever is earlier) within 15 working days of application provided that the energy transaction (between generator and consumer) is Intra-State. Banking of 100% energy will be permitted for a period of 1 year from the date of banking subject to the condition that the banked energy cannot be redeemed between February-June and TOD hours as provided from time to time. The incentives mentioned in …
