| Abstract | It is now well known that solar trackers pay for themselves with PV systems in field installations relative to fixed mounted systems by generating up to 1.4 times more kWh per kW installed. Solar trackers such as the JX Crystals' carousel tracker can also be profitably installed on commercial building flat rooftops. A commercially available JXC carousel tracker is equipped with six 200 W Sanyo planar PV modules generating 1.2 kW of electricity. The modules are mounted in two rows of 3 modules with each module mounted in landscape mode for low wind resistance. While the carousel tracker is desirable because it reduces the cost of solar electricity by producing more kWh, it is also desirable to reduce the cost of solar electricity still further by reducing the cost of the modules. Since mirrors are much cheaper than single crystal silicon solar cells, this cost reduction can be achieved by using 3-sun mirror modules. The module cost can potentially be cut in half. Various 3-sun module designs with similar sizes to the Sanyo planar modules are possible using 23% Sanyo cells or SunPower cells. More conventional 18% efficient Si cells can also be used. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
