Currently, man used the fullest potential of the solar system that able the man to use it as the source of renewable energy research. The project that includes in this research used the solar power as the source of energy for the circuit.This study used a solar cell battery charger, which is an instrument that sum up all the energy in a rechargeable battery by driving an electric current on it. There are given two tasks that need to take note in commonly using lead-acid based battery charges. First, it is task to fully pay attention for the self-discharge, frequently faster as practical in order to have a consistency in its capacity. Second, it is tasked to restore capacity. For both tasks cases, ideal operation needs to exactly identify the voltage of the battery. The aim of this project is to formulate a circuit that through the use of photovoltaic cells as a main basis would charge a 6-12V lead acid based battery. Depending to the given technology and capacity of the battery that being charge will determine the charge current. In this case, it is preferable to use 6V and 12V batteries. For this project to be able to complete, it is recommended to choose a voltage regulator circuit that has the ability to constantly maintain a certain voltage level; It is also recommended to use a voltage circuit checker in order to trace the voltage in the given battery before charging. Project Aim The aim of this project is to formulate and improve a circuit that has the ability to charge a 6-12V lead acid based battery, through the use of a solar panel as the main source of energy that will be carried out on the circuit; that will be able to allocate a wide range of use. Statement of Objective 1. To improve a charging circuit that can charge a 6-12V lead acid based battery through these of photovoltaic panels as a DC source. 2. To know how battery charger works. 3. Tounderstand more the Solar panel energy. Introduction This section explains the global history of solar energy. It also conducts a literature review. There are figures that this review includes; full corresponding details are stated. Word History - Solar energy Figure 1 Solar Energy The sun’s radiant light and its heat are the main sources of solar energy. Earth's weather and climate are being controlled by solar energy, as it gives life to all living things in the earth. Solar energy is a word that is being indicated as solar power; furthermore, solar power also refers to electricity generated from solar radiation. Biomass and hydroelectricity are said accountable for most of the present movement of renewable energy on Earth. However, for example wave power and its wind, solar energy only establishes minor energy resources. Actually, solar energy technologies have the ability to supply electrical generation through heat engines or photovoltaic means. Passive solar buildings also bring safe water use as potable in drinking, hot water, daylight, and for thermal energy; this excludes geothermal energy that was carried out from the energy that comes from the sun. Solar radiation is mainly included in this industrial type of solar energy that is recommendable to use for practical ends. There are two characteristic of solar technology: active or inactive. The solar cell captures, disseminates and translates sunlight. There are also solar energy techniques in order to convert sunlight into functional outputs, such as pumps, photovoltaic
INTRODUCTION Introduction This introduction chapter will include the summary of the whole project. This chapter includes the synopsis of the project itself, including its aim and detailed objectives. Project Overview During the 1973 Middle East war, the world of energy disaster influenced the interest of developing countries in studying the solar system…
The block diagram represents a 6-12V, 300mA circuit that charges batteries using solar cells that draw power directly from sunlight. The circuit can be divided into 3 parts: the voltage regulator, the comparator and the battery voltage checker. The voltage regulator controls the voltage and current from the solar panels to the battery.
It is triggered in vivo by a binding factor, VII, which is found in the plasma, to tissue factors, which is released from the endothelial cells in case of an injury. This enzyme speeds up the activation of factor IX, which team up with factor VIII, to catalyze the activation of factor X.
The company is a designer and manufacturer of photovoltaic cells, for large commercial rooftops (Solyndra 2011, 12). In addition to the United States, it has offices in Switzerland, Italy, Germany and France. Prior to acquiring the current name, it was formerly known as Gronet Technologies, Inc.
Over the recent past, economic growth in many parts of the world has given rise to many accompanying problems, chief among them being congestion (Banister D, 2003). This has been occasioned by the need to travel among the citizenry in their endeavor to perform their daily chores.
In both the countries development issues like education and health paradigms are important ingredients of government priority. But at the same time, the environmental factors have increasingly become major concern for them. Thus, looking from the
Without his help and guidance, I may have never attempted nor completed this difficult task. Secondly, I would like to thank those whose work is cited in the reference section for the inspiration they gave me through their ideas.
The technology advances and policy supports are great promoters of the advancement of the solar energy. Even though solar energy only produces 0.039 percent of the world’s energy supply it has the annual steady expansion rate of 28.1 percent
