- Disadvantages:Requires sufficient rooftop space, and installation can be complex.
Idea 2: Solar-Powered Generators
- Advantages:Can provide power during periods of low sunlight or at night if paired with battery storage.
- Disadvantages: Might require additional land or space for installation.
Idea 3: Solar Charging Stations
- Advantages: Provides a convenient way for students and staff to charge devices.
- Disadvantages:Limited in scope compared to a full solar power system for the school.
Idea 4: Hybrid Power System
- *Advantages:* Combines solar power with other energy sources (e.g., grid, generator) for reliability.
- *Disadvantages:* Requires complex control systems and might be more expensive.
Idea 5: Solar-Powered Water Heating
- Advantages: Can reduce energy costs for water heating, which is a significant portion of school energy
use.
- Disadvantages: Limited to applications where hot water is used extensively.
Stage 3: Generation of Ideas/Solutions
From the ideas discussed, the top three solutions to be considered further are:
1. Rooftop Solar Panels: Given its potential for significant energy generation and utilization of existing
space.
2. Hybrid Power System:Offers reliability and flexibility by combining solar power with other energy
sources.
3. Solar Charging Stations: Provides a practical and visible use of solar energy for the school community.
These ideas are selected based on their potential impact, feasibility, and the value they add to the
school's energy sustainability.
Stage 4: Development of Chosen Idea
Indication of Chosen Idea
The chosen idea is *Rooftop Solar Panels.* This solution is selected for its potential to generate a
significant amount of electricity and utilize existing school infrastructure efficiently.
Justification of Chosen Idea
Rooftop solar panels are chosen for their ability to provide a clean, renewable source of energy directly
to the school. Innovations could include integrating energy storage solutions to provide power during
nighttime or cloudy days and using smart technology to monitor and optimize energy production.
Steps to Achieve This
1. Assessment:Conduct a detailed assessment of the school's energy needs and rooftop suitability.
