You’ve been hired as a solar consulting team to determine whether your school can power all student laptops using solar energy. Your goal is to design a photovoltaic (PV) system and deliver an evidence-based recommendation supported by calculations, site analysis, and experimental data. 

Driving Question: Can we design a photovoltaic (PV) array that can charge all of our school’s laptop computers?

Part 1: Estimating Energy Demand and Solar Array Size 
A. Calculate the energy (kWh) to charge school laptops.
B. Estimate the size and number of PV panels required. 
C. Record assumptions and justify design choices.

Part 2: Selecting and Evaluating Potential Installation Sites
A. Identify and evaluate two potential solar array locations.
B. Use measurements, photos, or Google Earth data as evidence.
C. Recommend the optimal site based on sunlight, safety, and feasibility.

Part 3: Solar Efficiency Lab Proposal and Design
A. Develop a testable question and hypothesis.
B. Identify dependent, independent, and controlled variables.
C. Design your experimental procedure.
D. Submit your lab proposal for teacher approval.

Part 4: Conducting the Experiment and Applying Results
A. Conduct your approved experiment and collect data.
B. Calculate averages and percent changes, and graph the results.
C. Explain how your results relate to PV efficiency and system design.

Part 5: School Solar Array Investigative Presentation
A. Create a scientific poster or digital presentation.
B. Integrate energy calculations, site analysis, and experimental data.
C. Clearly explain your purpose, methods, results, and recommendations.

Part 6: Student Team Presentations
A. Present your findings to a peer or stakeholder audience (5-7 minutes).
