Hi Students!

I am dedicated to helping you master Class 11 Physics with clear explanations and easy methods. My study material is designed to make learning interesting and stress-free. You will get complete notes, formulas, solved numericals, and exam-focused guidance.

I am an English teacher and I need assistance with preparing an assignment. Please provide a clear, well-structured, and detailed explanation. The solution should be written in simple English and be suitable for academic use. If possible, include proper examples and step-by-step guidance.

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).
