Solar Tracker and Wind Guide Designs to Improve the Energy Conversion in a Hybrid Energy Harvester System

This study focused on improving the energy conversion of hybrid solar panels and a wind turbine system. The improvement was produced by enhancing the system with a solar tracker and a wind guide. A microcontroller operated the single-axis solar tracker based on a solar elevation database at -6.91N, 107.61E. The wind guide was an Omni Directional Guide Vane (ODGV), designed to support the drag-type Savonius turbine. The ODGV’s inside and outside diameters were 540 mm and 1000 mm, respectively. The wind guide had a 30° polar angle between fins and produced a torque of 0.128 Nm at a wind speed of 4 m/s. The solar tracker increased the system performance by 47% and the wind guide by 166%.

Development of Solar Powered Sprinkler Robot Based on Watering Plant Using IOT Approach

Nowadays, solar energy’s popularity is growing consistently every year, along with the growth of amazing solar technologies, which is considered to be one of the most popular. Non-renewable energy like petrol and gasoline is being replaced with solar energy, which is renewable energy. The main objective of this project is to design and simulate a robot solar system. The robot is developed using Arduino Mega 2560 as the main brain of the system. This system is equipped with a solar tracking system to track the movement of the sun and LDR is used to detect the presence of sunlight. The solar tracker is used to get the maximum efficiency of solar energy and reduce power losses. In addition, the solar tracker can rotate from 0° - 180°, which is the best angle for the solar panel to reach the sunlight. This robot will be attached to the sprinkler system to perform the watering process. This robot is developed for use in the agriculture field to reduce the manpower and cost of the watering process. Three analyses will be conducted in this project such as solar panel analysis, Wi-Fi connectivity analysis and sprinkler system analysis. The result shows the solar panel will gain the highest intensity of the sunlight at 12.00 pm and a sunny day compared to the other time and a cloudy day. The maximum range of Wi-Fi connectivity and the water pump, time used to finish the watering process and watering area will be discussed.

Performance Panel Surya Saat Gerhana Matahari Cincin Pada Tanggal 26 Desember 2019 Di Kecamatan Larangan Kabupaten Brebes

The purpose of this research is to know the performance of PV technology by using PV Solartracker on the eclipse Ring on 26 December 2019 by varying the net and dirty PV using themethod of Penyesuian sun position In one year. The study simulates using a solar panel capacity of3 watts and 6 volts with a lithium battery load capacity of 4000 mAh, the direction of the solarpanel is in the south with a tilt angle 230 in December each Stepnya solar tracker This 3- hourchanging angle 450, 900 and 1150 This research began from the hour 07:00 to 15:00 hours. Theaverage power of the solar power plant was received by 1.08 Watts, 4.24 Volt, 0.25 amper and netPV capacity of 2108 mAh, while with an average power of 0.83 watts, 4.36 volts, 0.19 Amper andgross PV capacity of 1524 mAh.
