Solar ray that fall down into the atmosphere will hit the solar panel and produce electricity that will operate the charge controller to charge the rechargeable battery. Later
the battery is fully charge and ready to operate when relay timer is counting down. This project will add a charge controller circuit, a relay timer and an inverter along with the
original system which is rechargeable battery and a water pump.
1.2 Problem Statement
Nowadays, most of the process of power generation leads to pollution towards the environment. The common effects are acid rain, atmosphere haze, pollutes water resources
and many more. It is because the power is being generated from the oil, natural gas, and coal. All this energy resource will contributes the environment pollutions whether being
well process or not. In addition, this kind of energy sources is categorized as nonrenewable energy which is limited available sources. So, to overcome this pollution problem, we need
to practice to use the renewable energy such as solar energy as optional energy sources. The solar energy is clean, renewable, and environment friendly. In this project, the solar
energy will be use to generate electricity that drives the automatic water pump for irrigation process.
1.3 Objectives
Every single project needs objective to control the whole project tasks. A project is considered successful if the entire objective achieved. So, several objectives were
established in completing this project. The objectives of this project are: Design the automatic water pump for irrigation application powered by renewable
energy solar energy. Develop a charge controller circuit and an inverter circuit in completing the
automatic water pump for irrigation application. Develop the automatic water pump for irrigation application circuit.
1.4 Scope
The scope of this project is to develop an automatic solar power system for irrigation application. It will consist of several electronics components such as charge
controller, inverter, timer and water pump as shown in Figure 1.2 below. Charge controller circuit will control the process of charging and discharging rechargeable battery while
inverter circuit will convert the DC supply to AC supply. This project is getting power supply totally from the Sun and generates electricity to the water pump. So, several
methods that suitable needed to make sure all the process run smoothly while developing the whole circuit.

CHAPTER 2
LITERATURE REVIEW
This chapter will discuss about the review of the past projects that related to this automatic solar power water pump for irrigation project and explanation of some the
components that will use in completing the project. It also consists of the basics theory which is understandable while doing the project. The part that will be discussing in this
chapter is renewable energy, solar energy, irrigation process, charge controller, rechargeable battery, timer, inverter and water pump.
2.1 Renewable Energy
Renewable energy is energy generated from natural resources such as sunlight, wind, rain, tides, and geothermal heat which are renewable. As the technologies to use
these natural energy resources evolve, the expense of using this renewable energy to generate electricity is coming more in line with the traditional fuels. The demand of the
renewable energy is increasing highly because of the world need to be saves from the pollut
ion for the good of next generations. If we don’t preserve the environment and control the pollution right now, our next generation will suffers at their time later. The
combustion of coal and fossil fuel might lead to the pollution to the environment. In addition, this kind of energy source is nonrenewable energy which is not last long enough
and cannot be use by all mankind later. So, we need to do more research on the renewable energy because of its benefits. The source of this energy is renewable, abundant and cost-
free. We only need the appropriate process to turn this kind of energy into electricity. But, the only problem that might become a problem is finding a low cost of harnessing this
energy which the technology is one step ahead.
