3. INTRODUCTION A major worldwide concern that has a substantial impact on ecosystems, facilities, and human health is climate change. This research aims to create a solar-powered fan that can offer relief from intense heat. The objective of this research is to develop a portable, environmentally friendly gadget that makes people feel safer and more at ease when they are outside, even in hot weather.

4. STATEMENT OF THE PROBLEM This study aims to assess the effectiveness of a solar-powered fan in combating heat waves and rising temperatures. How efficient is the solar-powered fan in terms of: • Energy efficiency, • Power consumption, and • Cooling output? What is the average lifespan of the solar-powered fan in terms of durability tests conducted at high temperature? What is the average energy output of the solar-powered fan during peak sunlight hours compared to low-light conditions?

5. METHODOLOGY R esearch Approach: Quantitative with an experimental design Goal: To explore how light intensity and environmental temperature affect the fan’s efficiency, cooling capacity, and durability Sampling Method: Systematic sampling to ensure a representative and feasible sample Sample Size: 100 Senior High School students from Emilio Jacinto National High School (EJNHS) 10 street vendors located near the school

6. METHODOLOGY A structured survey will be administered to both students and vendors. Likert scale questions include: Strongly disagree, disagree, neutral, agree, strongly a gree. We will also be adding an open ended question to further enhancement of the Solar-Powered fan. Data collection will be divided into two phase which is Prototype testing and Respondent feedback.

7. METHODOLOGY After data collection, the study will use descriptive and inferential statistics to analyze and summarize the solar-powered fan’s performance. Key statistical methods will include: • Frequency and Percentage Distribution • Mean (Average) • Standard Deviation • T-Test (Independent Samples) • Pearson’s Correlation Coefficient

8. METHODOLOGY In summary, the researchers employ systematic sampling, accurate data collection, and robust analytical methods to assess the feasibility of solar-powered fans in real-world environments. The findings will contribute to the growing knowledge of renewable energy applications and inform future advancements in cooling technologies.

9. METHODOLOGY MATERIALS: Solar-Powered System Solar Panel – Harvests solar energy to power the fan and charge the battery. Solar Charge Controlle r – Regulates the energy flow from the solar panel to the battery to prevent overcharging. Rechargeable Battery (Li-ion or LiPo) – Stores the solar energy for later use, powering the fan when sunlight is unavailable. Power Management Module – Manages the charging and discharging of the battery to optimize energy use.

10. METHODOLOGY MATERIALS: Cooling (Misting and Airflow) Misting Nozzle – Distributes water mist to enhance cooling and reduce air temperature. Water Reservoir – Holds the water used for the misting system. P ump (optional) – Circulates water from the reservoir to the misting nozzle, providing a continuous misting effect. Fan Blades (Propeller) – Creates airflow to cool the environment.

11. METHODOLOGY MATERIALS: Temperature Monitoring and Automatic Speed Adjustment Temperature Sensor (e.g., DHT22) – Measures the ambient temperature to adjust the fan speed accordingly. Microcontroller (e.g., Arduino) – Processes data from the temperature sensor and sends signals to control the fan’s speed. Display (LCD/LED) – Shows the temperature readings to provide real-time feedback. PWM Controller – Controls the fan motor speed based on the temperature readings from the sensor.

12. METHODOLOGY MATERIALS: Energy Storage and Charging for Other Devices SolarCharge Power Bank – Stores excess energy from the solar panel and allows it to be used later or to charge other devices. USB Charging Port – Allows the fan to charge external devices, such as smartphones or tablets. Battery Protection Circuit – Protects the battery from overcharging and over-discharging, ensuring safety and longer battery life. USB Cable – Used to connect external devices for charging.

13. METHODOLOGY MATERIALS: Assembly and Circuitry DC Motor (Fan Motor) – Drives the fan blades to generate airflow. Relay/Switch – Controls the fan motor, enabling or disabling its operation. Enclosure – Houses and protects all the components from dust, damage, or moisture. Circuit Board – Provides a platform to organize and connect all the electrical components. Wires and Connectors – For connecting components and ensuring proper electrical flow. Resistors, Capacitors – Stabilize and optimize the electrical flow within the circuits.

14. METHODOLOGY Ingredients: Water – Used in the CoolFlow Hydration System to generate the misting effect that helps cool the air. Cooling Gel (optional) – Can be used (if incorporated) to enhance the cooling process in the misting system or to maintain the coolness longer. Refillable Water Reservoir – Holds the water required for the misting system and needs to be periodically refilled. Lubricants (optional) – For the fan motor or any moving parts, to ensure smooth operation. Eco-friendly Cooling Agents (optional) – If you choose to add any eco-friendly solutions to improve misting or prevent bacterial growth in the water reservoir.

15. METHODOLOGY Step-by-Step 1. Connect the solar panel to the charge controller and battery. 2. Install the misting nozzle and connect it to the water reservoir. 3. Mount the fan blades onto the DC motor and connect to the PWM controller. 4. Integrate the temperature sensor, microcontroller, and display for real-time monitoring. 5. Add a USB charging port and test its functionality. 6. Enclose all components in a protective casing. 7. Test the system for efficiency and functionality.

16. Conclusion In conclusion, our study shows that the solar-powered fan is an effective and sustainable solution for combating high temperatures. Its innovative features, such as a misting system and temperature sensors, enhance comfort while reducing energy consumption. We believe this research lays the groundwork for future advancements in solar-powered technologies.
