Lab 2 Solar Data Analysis

Aim

• To analyse solar data for selected locations in Fiji

---

Part 1: Monthly and Annual Data (Suva, Nadi, Labasa)

1. Data Source
   • Monthly average solar data from 19842017.
   • Locations: Suva, Nadi, Labasa.
   • Data downloaded from NASA (power.larc.nasa.gov).
   • Provided in Excel file.
2. Monthly Variation Analysis
   • Choose one location and one specific year.
   • Construct a graph showing monthly solar insolation variation.
   • Explain reasons for variation (e.g., seasonal changes, cloud cover, rainfall, sun angle).
3. Annual Average Analysis (Single Location)
   • Calculate annual average solar insolation for each year (19842017).
   • Construct a graph to show trend over 33 years.
   • Discuss whether solar insolation is increasing, decreasing, or stable.
4. Comparison Between Locations
   • Construct a graph comparing annual solar insolation trends of Suva, Nadi, and Labasa.
   • Discuss differences over the past 33 years.
5. Monthly Comparison Between Locations
   • Choose one year.
   • Graph how solar insolation varies monthly across all three locations.
   • Discuss regional differences in Fiji.
6. Application
   • Discuss how and where this solar data can be used (e.g., solar panel design, PV system planning, energy policy, site selection).

Part 2: Hourly Data (Nadi Only)

1. Data Source
   • Hourly irradiance data from renewables.ninja.
   • Location: Nadi.
   • Data in second Excel worksheet.
2. Daily Irradiance Analysis
   • Choose one day in January.
   • Construct a graph showing hourly irradiance variation.
   • Explain reasons for variation (sunrise, sunset, solar altitude, clouds).
3. Application
   • Discuss practical uses (e.g., battery storage sizing, peak generation timing, grid planning).

Initial Post (Required)

Respond to ONE of the following prompts. Your post should be at least 150200 words and clearly explain your reasoning in your own words.

Option 1: Speed vs. Velocity
Chapter 2 emphasizes the difference between speed and velocity.

• Explain the difference between these two concepts.
• Give a real-world example (driving, walking, sports, etc.) where speed stays the same but velocity changes.
• Why is direction important in physics?

Option 2: Acceleration in Everyday Life
Acceleration does not only mean speeding up.

• Describe a real-life situation where an object is accelerating even though its speed is constant or decreasing.
• Explain how this example connects to the definition of acceleration from the chapter.

Option 3: Falling Objects and Gravity
Chapter 2 discusses motion under gravity and shows that objects fall with the same acceleration (ignoring air resistance).

• Why does a heavy object seem like it should fall faster than a lighter one?
• Use an example from everyday life to explain how air resistance can affect motion.

Option 4: Newtons First Law (Inertia)
Newtons First Law states that an object will remain at rest or move at constant velocity unless acted on by a net force.

• Describe a situation youve personally experienced that demonstrates inertia.
• Identify the force that eventually changed the objects motion.

Reply Posts (Required)

Reply to at least TWO classmates (minimum 75 words each).

In your replies:

• Ask a thoughtful question or
• Clarify or expand on their explanation or
• Connect their example to another concept from Chapter 2 (velocity, acceleration, force, gravity, etc.)

Avoid responses like I agree without explanation.
