Introduction

According to A. Hurst of SOL Inc., “without access to electricity, nearly 1.6 billion people, or 30% of the world’s population, do not have reliable street lighting”. A Street light is a proven piece of equipment to enhance the safety, comfort, educational capability, commercial and social life of a community. A monumental demand for electrical power for industrial use serves as a big hindrance to the propagation of the street light especially in the Philippines. An acceptable solution to this problem is the provision of a reliable and low-cost type of lighting system that does not require power from the local power companies.

A Solar powered street light is the best solution for providing outdoor light that does not require power from the local power generators. The solar powered street light does not require an overhead or underground electrical wiring, does economical. Furthermore, it will not necessitate any additional power from the grid line avoiding the use of electrical distribution equipment which are sometimes unreliable and unavailable.

Solar powered street lights will be relied upon to provide illumination every night. With the installation of a battery or a “power bank” as we now call it, properly designed solar lights will be illuminating the night for at least five nights even if there is inadequate sunlight during day time. There is no doubt that the solar powered street light is a versatile form of a lighting system. It will illuminate roads, villages, barangays, school, and will help improve our day to day life.

It is very clear that the solar power street lighting system packs a number of advantages to the community. Productivity will surely increase because working days are lengthened. This piece of equipment will extend the number of hour on commercial activity thereby increasing the economic stability of a rural community. Students will be safe at night, and creates opportunities for further educational activities. A community that has an effective and reliable type of illumination decreases urban migration, because the community will have the same comfort of safety and security as in the urban areas. Crime is also bound to decrease because the community police can now see any criminal activity which may have been covered in darkness in the past.

The Solar powered lighting system is readily available, proven and economically viable. If only our nation can dedicate a portion of its budget to enhancing the technology. One issue commonly cited is the lack confidence in solar lighting as a reliable means of providing outdoor lighting. Though there have been stories of success and failure on solar projects in the Philippines, but with considerable vigilance and a good amount of focus, the solar powered lighting can be successfully introduced in all of the community.

Objectives of the Study

The primary concern of the study is to install a Solar Powered Street Lighting system in Sapang Patay, San Isidro II, Paombong, Bulacan.

specific Objectives

i. Determine the most efficient utility design for a solar powered street lighting system suitable for Sapang Patay St. San Isidro II, Paombong, Bulacan.

ii. Develop a lamp post design that is uniquely made for the worst conditions of a fishpond area.

iii. Assemble and fabricate a solar powered street light system and conduct experiments and modifications.

iv. Conduct monitoring activities to test the efficiency of the system.

Significance of the study

This study shall benefit the residents of Sapang Patay St. in San Isidro II, Paombong, Bulacan. It has been foreseen that more residents shall feel free to walk at night due to the illumination provided by the project. It has been arranged through a Memorandum of Agreement with the Barangay Council of San Isidro that the officials shall exert extra effort to ensure the equipment will be protected from thieves and alike.

Scope and Delimitation

The study will deal with the development of a solar powered street lighting system that will be used to illuminate Sapang Patay st., in San Isidro II, Paombong Bulacan. The system will be installed along the road leading to the center of the residential area. The study will also deal with the monitoring and data gathering activities that will determine the efficiency of the system.

Conceptual Model of the Study

Image 1

The model in figure 1 consists of three major components which include the input, the throughput and the output. The input consists of planning and data gathering, hardware requirement analysis, revisions, tools and equipment, supplies and materials and labor. The throughput includes the designing, constructing, testing and revising. The output of the study is Solar Powered Street Light for Sapang Patay.

Methodology of the Study

The descriptive and developmental method of research was used in this study. The descriptive method of research involves a gathering of information about the present existing conditions. This method, basically involves identifying and defining the problem, selecting appropriate sources of data, adopting appropriate techniques for data gathering, procedures, analyzing, describing and interpreting the data.

Developmental research, on the other hand, is a research method that can provide practitioners with important data. It is mainly focused on the design, development and evaluation of products and processes. This study could be described specifically as a project development because it is a creative development of a project based on a thorough determination of the present situation and the goals at hand.

Respondents

Purok Sapang Patay in the Municipality of Paombong Bulacan will serve as the project’s respondents. It is an area of mainly fishpond within its vicinity.

A 40% sample size shall be chosen using stratified random sampling procedure.

The sampling shall involve a 30 head of the family in the area together with the 10 barangay leaders. Table 1 will show the respondents together with its total population and sample size.

Table 1: Respondents of the study

Respondents Population Sample Size
Head of the Family 30 12
Barangay leaders 10 4
Total 40 16

Data Instrument

The instrument used in the study was a survey-questionnaire. The questionnaire was divided into two parts. Part one is the profile of the respondents. The second part is the respondent’s perception regarding the functionality, durability, physical features, cost and safety of the solar powered street light.

The questionnaire uses the Likert- type scale of 1-5. Five (5) being excellent and one (1) is poor.

Data Analysis

The data gathered from the respondents were tabulated and analyzed to determine the functionality, durability, safety and physical features of the project.

The weighted mean for each criterion in the instrument was computed to determine the functionality, durability, physical features, cost and safety of the project. Table 2 shows the interpretation of the computed weighted mean for each indicator.

Table 2: Interpretation of the weighted mean

Scale Verbal Description
4.21 – 5.0 Excellent
3.41 – 4.20 Very Good
2.61- 3.40 Good
1.81- 2.60 Fair
1.0 – 1.80 Poor

Results and Discussions

Table 3 shows the summary of the evaluation and the mean on each criterion on the functionality, durability, physical features, cost and safety of the solar powered street light.

Table 3: Summary of the ratings

Criteria Mean Interpretation
