Design And Construction Of A Solar Bag

ABSTRACT

This paper demonstrated a step by step process in designing a solar powered charging bag that is capable of charging mobile devices efficiently. A selection of existing products available on the market were reviewed and compared to ascertain the cost, size, and output capabilities. Next, the solar cell types and regulators were compared and their respective merits were also investigated. The charging system was then designed and tested before being integrated with the solar bag. The results clearly showed that the system managed to charge the mobile phone. However, it was found that the excessive power dissipation has caused the linear regulator to generate significant heat.

1.0                                                        INTRODUCTION

Solar is one of the most abundant sources of renewable energy [1–4], with the potential capability of generating enough power to meet the demands of the entire planet. It was calculated theoretically that the amount of sun received on earth for one day has the capability to meet the demand of the world for more than 20 years [5]. Despite the huge potential, solar photovoltaic only provides 1.2% of the world’s electricity [6].

The harnessing of solar energy is still very much ongoing with the advancements in solar technology constantly improving. There are many applications where solar energy is utilized – from the very big application, such as generating electricity for homes and industry from solar fields, to the very small applications like powering the calculators. The possibilities are extensive.

There are a varying number of products already on the market that utilise solar energy for storing and charging devises. The products range in all shapes and sizes from fully integrated to attachable. As with Generally, the power of the solar bag was ranging from 6W to 7W with the output voltage of between 5V and 6V. The bag that come at greater cost tended to have a battery pack incorporated. The addition of this does increase the overall weight as expected.

The purpose of the paper is to develop a different prototype of solar powered charging bag that is capable of charging a mobile devices efficiently. The design would have to meet certain criteria including durability, reliability, practicality and low cost. In order for this to be achieved successfully, research, design, testing and analysis are carried out.

1.1                                                   AIM OF THE PROJECT

The main aim of this work is to build a portable, mobile and light in weight solar pack which is packaged in a bag for the purpose of charging portable rechargeable devices.

1.2                                         SIGNIFICANCE OF THE PROJECT

1. Solar bag is light-weight, hence making it easier to carry.
2. Solar bag carry a green energy source for the environment.

• Flexible solar panels also are light and portable, as well as waterproof.

 

1.3                                                 SCOPE OF THE PROJECT

The solar bag usually contains a flexible monocrystalline solar panel, battery, charge controller, plugs, cords and light bulbs. It provides users with power up to 120 watt-hours/day, capable of powering electronic equipment rated up to 300 W depending on the design.

1.4                                          APPLICATION OF THE PROJECT

• It can also be utilized in international aid, disaster relief, emergency power and field research.

ï‚· Solar bag can also power laptops for up to 3 hours.

ï‚· After an exposure of about six hours, it can power an emergency light for 14 hours.

ï‚· Solar bag can also be used to power medical equipment and humanitarian relief efforts where power from the utility grid is not available.

ï‚· These types of bag can also be used to power cameras for use in remote areas.

1.5                                           LIMITATION OF THE PROJECT

• It can only be recharged with solar energy through solar panel
• The duration of the charged when in used depend on the number of cell used.
• Using solar energy for this device means that charging the power bank during cloudy or raining time becomes a problem.

1.6                                        PROJECT WORK ORGANISATION
