SELF-WATERING SYSTEM THROUGH A SOLAR INSTALLATION
Sergio David Garzón Bermúdez
Andres Felipe Gomez Moreno
Maria Camila Ibarra Rios
INTRODUCTION
Solar energy is that which takes advantage of the sun's radiation from which electrical energy can be obtained through photovoltaic panels. This can be used to solve different needs such as agricultural applications, such as self-irrigation systems which require the collection of rainwater, the lighting of rural areas that do not have electricity network service.
PROBLEM QUESTION
How effective is a solar self-watering system in the plant nursery at Gimnasio Oxford School ?
OBJECTIVES
General Objective
●Carry out a pilot solar installation of automatic irrigation powered with sunlight for a radish crop and verify its effectiveness by means of the results obtained in the crops.
- ● Take advantage of the rainwater that is currently collected in the nursery to irrigate the plants through the system that will be implemented and improve the supply of collected water with an additional tank.
- ● Take advantage of sunlight to generate electrical energy for the self-watering system.
- ● Implement an irrigation system that maintains humidity in the 3-meter section of the south bed of the plant nursery in the institution that operates autonomously and automatically.
Specific Objectives
- ● Develop an experimental radish crop that is maintained through the self-watering system and compare it with our control crop.
- ● Get the experience of installing a solar mount and automatic irrigation installation as well.
- ● Prepare and record data in a field journal monitoring the crops in the nursery to tabulate our information and conclude about it .
- ● Disseminate findings and recommendations to the Oxford community.
JUSTIFICATION
The purpose of this project is to show that an installation of this type is not going to increase the energy bill of the institution and, on the other hand, to show how practical it is to have the nursery watered in an automatic way without the need for a person or operator be constantly aware of its watering.
THEORETICAL FRAMEWORK
It is a technology that meets human needs without compromising the environment, since it is extracted it does not interfere with the natural course.
Sustainable energies
Sustainable energies in Colombia
In Colombia, energy comes mainly from hydroelectric plants and fossil fuels that are depleted over the years.
According to the world energy council (WEC), Colombia is ranked 18th worldwide in the use of sustainable energy.
Solar energy
The sun releases more energy into the earth than is required to meet global needs. Solar energy is one that takes advantage of the solar rays and makes them useful to generate solar energy,
The solar power that planet Earth receives is about 173X1012 kW per year. The planet receives average energy at 3x1017 kWh per year, equivalent to 4000 times the consumption of the whole world in a year (7X1013 kWh / year)
How much energy does the sun produce?
Are devices designed to capture electromagnetic radiation from the sun, for later use and transformation into various forms of useful energy.

Irrigation system
Set of elements that interact collectively with the sole purpose of providing water to crops.
Parts of the irrigation system
- Sprinklers
- ●Irrigation emitters
- Drainage system
- ●Pumping station
- Pipes
- ●Valves
- Humidity sensor
It is a plant of the Brassicaceae family that is grown mainly for its edible roots, it is usually known for its red color and its spicy flavor.
What is radish?
The cycle, from sowing to harvest, is approximately 3 to 6 weeks, depending on its variety. Growing does best in cool climates.
The radish seedling will grow approximately 3 days after sowing
Radish cultivation cycle
HYPOTHESIS
It was observed that the Gimnasio Oxford School did not have any mechanism that would allow it to support the nursery autonomously, given this we focused mainly on the implementation of a solar installation for the development of a self-watering system in the nursery, this for the collection clean energy and produce environmental benefits.

ACKNOWLEDGMENTS
We mainly want to thank God, who gave us the wisdom and commitment to carry out a successful development of this project, in addition to Mr Alfonso Hassan, since he guided us and taught us new knowledge in front of the parts that involved the whole process of implementation of the self-watering system, to our tutor, Gino Vargas, for being always attentive in carrying out any correction and suggesting us new ideas to improve. To our parents, for accompanying us and giving us the best energy that day by day was needed. And finally to the directives of the institution, to allow us to make use of the nursery of the institution and the required permits throughout the process.
