With the increased trends of industrialization and global economic growth leading to the everchanging petrol prices and other price hikes, private transport system has become a costly affair. All these problems can be addressed with innovation. One of the most feasible solutions is turning towards renewable energies to solve the issues i.e., increasing the use of renewable energies like solar power in the place of fossil fuels. Everyone’s dream of owning a commercially viable solar vehicle is slowly becoming a reality. Electric vehicles are now available at an affordable price. This opportunity is taken towards the design of a Solar powered two-wheeler. Designing a solar vehicle is a multidisciplinary subject that covers the broad and complex aspects from various subjects. In the designed vehicle, solar panel is used as the power source and developed voltage, stored in the battery, is used to the drive the permanent magnet DC motor which drives the rear wheel of the vehicle.

The aim of this paper is to boost the power output of the hybrid energy harvester effectively and to provide electrical optimization for a hybrid energy harvesting system that produces two electrical outputs from a single source of mechanical input namely vibration. Two different electrical outputs are produced by using the concept of piezoelectricity and electromagnetic induction. In this paper, an electrical equivalent is obtained for the standalone piezoelectric system and the electromagnetic system. The rectification of the piezoelectric system along with its results is discussed. Different circuits for amplification is studied and simulated to improve the voltage. All the practical experimental outputs and the different software used to gain these outputs are recorded. The various applications of the hybrid system are reviewed and discussed.

The I-V characteristics of solar cell are affected due to solar irradiation and local temperature conditions. The solar cell array output power varies due to variations in radiation and cell temperature. Various maximum power point tracking (MPPT)algorithms are developed for extraction of maximum powerfrom a solar array when it operates at MPP which varies continuously whenever there is change in solar panels temperature or irradiance. The solar cell array is integrated with intermediate converter to utilize extracted maximum power from the solar panel. This integrated system operated at high efficiency and the low operating cost. This paper discusses about Perturb & observes algorithm implementation by considering only voltage profile of solar cell module. The integrated system comprising of solar array, boost converter along with MPPT is simulated using MATLAB/SIMULINK tool.

Energy Monitoring is one of the most important routine that is carried out in every industry as a key process of Energy Management. The prime reason for energy metering is to ensure that the processes are done efficiently. Through energy monitoring, the energy consumption on a particular period is easily obtained thus helping to find the energy usage in a day and taking steps to improve energy efficiency. The energy consumption in a particular period of time is obtained using a digital meter. The meters in today’s industries are digital meters and support serial communication. The energy meters present in the plant are connected to the server and are made to transfer their data directly to the server. This eliminates the man-hours wastage of every employee who performs this energy monitoring. The Man hours for a medium sized plant with 75 Digital meters spread across the plant was reduced to 2 hours/day.

Solar energy will be the important source of energy for the future. Solar cells transform energy from an essentially unlimited source sun. PV system virtually zero running cost energy is the input source of power. It is environment friendly. The DC-DC converters are used to increase the efficiency of PV system. This paper envisages the comparison of the two topologies of two converters; Zeta and high voltage gain DC-DC Converter.
