Description Solar panels are devices that are capable of transforming energy stored within sunlight (electromagnetic waves coming from the sun) into electrical energy that can be used to power devices. Suppose that a certain solar panel can harvest 15% of the total energy found in sunlight. If we are given the intensity of the electromagnetic radiation that is coming from the sun, we would like to determine the area of the solar panel required to power (a) a calculator that requires 70 mW of power and (b) a car that requires 30 HP to drive with a constant velocity.

About National Digital Library of India (NDLI)
NDLI logo

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.
