2. About our product The self-cleaning mechanism for solar panels uses a robust brush and a water squirting system to efficiently keep panels free from dust, dirt, and debris, ensuring optimal performance. This innovative system maintains cleanliness and enhances the efficiency of solar panels. Components: Rotating brush. Water squirting system. 2

3. Part Workbench: This is where you create the fundamental building blocks using features like extrude, cut, sweep, etc., to define the shape and form of your parts. Assembly Workbench: Once you have individual parts, you can bring them together and define their relationships and movements in assemblies. 3

4. Assembly Workbench: An assembly workbench is a specialized workspace where intricate components come together with precision. Equipped with tools for meticulous fitting and alignment, it ensures each part of a product is seamlessly integrated. From delicate electronics to mechanical assemblies, the workbench provides a stable platform for assembling and testing, guaranteeing high-quality craftsmanship and functionality before deployment 4

20. Table Below is a chart comparing the key metrics of solar panel performance and maintenance before and after the implementation of a self-cleaning mechanism 20 METRIC BEFORE SELF CLEANING MECHANISM AFTER SELF CLEANING MECHANISM Energy Efficiency 75-85% (due to dirt and debris) 95-99% (consistent cleanliness) Maintenance Frequency High (monthly manual cleaning) Low (automated, periodic cleaning) Maintenance Cost High (labor and equipment) Low (initial investment, minimal upkeep) Safety Lower (manual cleaning risks) Higher (automated system, remote control) Water Usage High (manual cleaning) Low (hydrophobic coatings, waterless options) Operational Downtime Higher (due to cleaning schedules) Lower (automated, scheduled cleaning) Environmental Impact Moderate (water and resource usage) Low (minimal water usage, efficient)

21. Constraints Applied in Assembly: Mate Constraints : These include coincident (for aligning faces or points), parallel, perpendicular, tangent, concentric, and distance mates. They ensure that parts are properly aligned and positioned relative to each other . Angle Constraints : Limiting angles between components to simulate real-world limitations or operational requirements . Width and Thickness Constraints : Ensuring parts fit together correctly based on specified dimensions. 21

22. Difficulties we faced Developing our self-cleaning mechanism presented several challenges throughout the project. One of the main difficulties involved optimizing the brush design to ensure it effectively removed debris from solar panels without causing damage. Additionally, achieving precision and efficiency in the water spraying system proved to be another significant hurdle. These challenges required extensive testing and iterative improvements to strike the right balance between gentle cleaning and thorough maintenance, ultimately ensuring our solution delivers optimal performance and reliability in solar panel upkeep. 22

23. What We Learned: Through this project, we gained invaluable insights into advanced automation and precision engineering techniques, refining our ability to design robust, efficient systems. Additionally, we deepened our understanding of sustainable energy solutions, recognizing the pivotal role of clean technologies in mitigating environmental impact. Crucially, we learned the importance of integrating user-friendly maintenance features, ensuring that our innovations not only perform optimally but also enhance usability and reliability for our customers. 23

24. Marketing Strategy: Our marketing strategy centers on showcasing the effortless maintenance benefits, emphasizing how our self-cleaning mechanism enhances energy efficiency while highlighting its cost-effectiveness. By emphasizing these advantages, along with the environmental benefits and user-friendly design, we aim to appeal directly to customers looking for dependable, sustainable energy solutions that require minimal maintenance. This approach not only underscores our commitment to innovation but also addresses the practical needs of consumers seeking reliable long-term solutions for clean energy production. 24
