• Sunlight is a promising renewable energy resource for Singapore.
• Sunlight is one of Singapore’s four national “switches” (natural gas, solar, regional power grids, emerging low-carbon alternatives)
• The lack of space for deployment due to Singapore’s small size and the intermittency of sunshine due to cloud cover and urban sharing are some challenges associated with solar panels
• Scientists and engineers are constantly innovating to overcome these limitations so that solar panel deployment is more viable for Singapore

 Introduction: 

In an era where sustainability and clean energy are at the forefront of global conversations, harnessing the power of the sun has become a key focus. Solar panels, also known as photovoltaic (PV) panels, are instrumental in converting sunlight into electricity. But did you know that the efficiency of these panels can be significantly enhanced by adjusting the tilt angle to maximize exposure to sunlight?

Understanding Solar Panels: 

Solar panels are devices that capture sunlight and convert it into electricity through the photovoltaic effect. This process involves the interaction of photons (light particles) with semiconductor materials, generating an electric current. The electrical energy produced by solar panels can be utilized to power homes, businesses, and even entire communities.

To visualize and understand the impact of tilt angle on solar panel performance, an interactive model facilitated by Easy JavaScript Simulation (EJSS) allows users to simulate the positioning of solar panels at various tilt angles and observe the corresponding changes in power output. This hands-on approach helps users grasp the significance of tilt angle optimization in harnessing solar energy efficiently.

Within the interactive simulation, users can click the "play" button to initiate a simulated timeline that mirrors the sun's journey from east to west. This feature allows individuals to witness in real-time how the graph captures the fluctuating output power over the day. Users can actively experiment with the tilt angle during this time. By adjusting the tilt angle while the simulation is in motion, users can observe the immediate effects on power output, providing a hands-on experience that enhances understanding and appreciation for the significance of tilt angle optimization in solar panel performance. It's an educational journey that brings the complexities of solar energy conversion to life.

• Increased Energy Production: Proper tilt angle optimization can lead to increased exposure to sunlight, resulting in higher energy production by solar panels. 
• Seasonal Adaptability: Adjusting the tilt angle allows for seasonal adaptation, ensuring optimal energy generation throughout the year. 
• Financial Savings: Maximizing power output means more efficient use of solar energy, potentially leading to reduced electricity bills and increased cost savings.

Factors affect electrical energy such as Weather Cloudy Rainy etc

However, the impact of weather cannot be overlooked in this optimization process. Cloudy or rainy days pose a significant challenge to solar energy generation, as they reduce the amount of sunlight reaching the solar panels. This reduction in sunlight can lead to a decrease in energy output, affecting the overall efficiency of the system.

 

 

Research

Activity 1: Energy output from a solar panel

• A solar panel contains multiple solar cells.
• Each of these cells generate electricity from light.
• This process is called the photovoltaic effect.
• Several factors determine how much electricity a solar panel can generate.

2. Adjust the controls such as "Angle of Tilt of the Solar Panel" to see how the different variables affect the output of the solar panel

Activity 2: Deploying solar panels in Singapore

1.  When you used solar panel simulation, you would probably have realised that: 
    

   The amount of energy obtained from solar panels for generating electricity is not consistent. It is dependent on several external factors such as day of the year the angle of tilt of the solar panel the availability of direct sunlight, example 6am to 6pm daytime the weather such as sunny, rainy or cloudy    as you explore the simulation, check that these externl factors can be observed.

    

   Intermittent energy resource

   Since the amount energy available from the Sun is NOT consistent, we say that sunlight is an intermittent energy resource. 

   Intermittency is one of the reasons why sunlight is currently not the main contributor for electricity generation in Singapore.
