ABSTRACT 40% of Philippine population lives off less than $2 a day. Many are unable to afford the electricity some of them they are

using candles as a light source. The problem is if this is not discovered, around 25,000 low

income homes will continue to suffer in darkness, not knowing there is hope when we see light

the question is: How does varying the amount of bleach affect the power rating

of the solar energy bottle? What is the difference in the amount of light produced on Bleach,

Alcohol, and Dish Washing Liquid as solute for the Solar Energy Bottle?

Significance of the StudySociety : it provides a clean and renewable source of light for years . This aim to lessen and help the number of families that suffers

from darkness .

Environment the only way they can have access to light is through burning

dirty fuels, such as kerosene, which is not only unhealthy when burned indoors

The researchers found a friendly way to help the people who can’t afford a light bulb in their home.

D. Scope and Limitations: This reseachers will only focuses on finding or using the

alternative ways of solar energy bulb.

Chapter IIA. Literature: This inventory is first to be made by the Massachusetts

Institute of Technology (MIT). The product will be for those who can’t afford to pay electric

consumption. IIlac Diaz the Filipino who adopts the inventory, implemented a

“local entrepreneur” business model.

B. Studies: The system is only capable of producing light during the day, it

has positively impacted the daily lives of people in the Philippines, where the solar bottle bulb has been widely installed

Chapter IIIMethodology

A. Research Design: The bulb consists of a standard plastic bottle filled with purified

water and bleach, then inserted into the roof. the bottle produces a source of light with an intensity equivalent to

a 55-watt electric light bulb.

B. MaterialsItem Quantity Description

Bottle 1 piece 1.5 clear plastic bottle

serve as the container of

soft drink (e.g. coke, royal)

Water 1. 5 Liter Purified drinking water

Alcohol 50 mL Ethyl alcohol

Bleach 50 mL An as zonrox

Dishwashing liquid 50 mL It is use to wash dishes

(e.g. Joy)

Chapter IVFinding and Analysis of Data

A. Findings As you can see on the data, the bleach has more

effectively in terms of being a variable on making the

Solar Energy Bulb. Brightness

Bleach

Ethyl Alcohol

Dishwashing liquid

B. Analysis of Data: With just a plastic bottle, water, and bleach, the researchers has

found a way to produce a light that is up to 40 or 60 watts . The amount of bleach doesn’t affect the amount of brightness the

solar bottle produced

C. Procedure of making

1. The clear plastic bottle is filled with water and some capfuls of bleach.

2. The bottle is placed on rooftops. Sunlight is refracted through the water and into the room below.

3. The Solar bottle gives out as much light as a 40-to-60-watt bulb.

D. Product of testing The group builds a model house to see if the product really works in

the sunlight after putting the bottle on top of the house they will use the solar cell

Chapter VSummary, Conclusion and Recommendation

 A. Summary Based on their experiment through the light it has produced, they

determine the right alternative solute in making solar energy bulb. It can also help the earth to lessen the garbage and plastics

through recycling of materials.

B. Conclusion How does varying amount of bleach affect the brightness

of solar energy bottle? that the solar bottle is an effective in giving the source of light and bleach is more effective to use in the solar bottle because the

light is clearer not like alcohol and dish washing soap . What is the difference in the amount of light produced on

bleach, alcohol, and dishwashing liquid as solute for the Solar Energy Bottle?

the light that bleach has produced 40-60 watts which overpowers the remaining alternative

C. Recommendation This project is a concerned student to conduct further studies regarding

the solar bottle. Current findings about the topic can help the community to save the

electricity of those who cannot pay their electric bill A lot of people can used this product and it can lighten their darkest

room.
