This paper aims to achieve accurate maximum power from solar photovoltaic (PV), its five parameters need to be estimated. This study proposes a novel optimization technique for parameter estimation of solar PV.

To extract optimal parameters of solar PV new optimization technique based on the Jellyfish search optimizer (JSO). The objective function is defined based on two unknown variables and the proposed technique is used to estimate the two unknown variables and the rest three unknown variables are estimated analytically.

In this paper, JSO is used to estimate the parameters of a single diode PV model. In this study, eight different PV panels are considered. In addition, various performance indices, such as PV characteristics, such as power-voltage and current-voltage curves, relative error (RE), root mean square error (RMSE), mean absolute error (MAE) and normalized mean absolute error (NMAE) are determined using the proposed algorithm and existing algorithms. The results for different solar panels have been obtained under varying environmental conditions such as changing temperature and constant irradiance or changing irradiance and constant temperature.

The proposed technique is new and provides better results with minimum RE, RMSE, NMAE, MAE and converges fast, as depicted by the fitness graph presented in this paper.

The purpose of this paper is to evaluate the effectiveness of the internet as an educational tool and to explore what role it plays in the educational system.

The study was purely conducted on a sample of 120 users of Delhi College of Engineering (DCE) Library. The questionnaires consisted of 20 main questions with many of the main questions having a number of subquestions. The questionnaire contained five open‐ended questions.

This case study provides awareness of various internet tools and services used by the library staff and library users. The library will aware of new internet services and provide their users.

This is case study of Delhi College of Engineering (Central Library) and this study will also be useful and important to those users who are already studying in different institutions and colleges.
