Our project is to design an automated solar panel cleaning mechanism that detects obstructions (bird droppings, leaves, etc.) on the panel and automatically cleans them away. Since solar panels are outdoors, they are prone to shading due to natural debris. For large solar installations in remote areas it could become difficult and/or expensive to monitor and clean hundreds of large solar panels. Because of the build-up of dirt on a cell in a solar module, hot spots are created and heat is produced instead of electrical power. This reduces efficiency and life-time of the solar panel. Our project would greatly reduce the amount of service calls for cleaning, resulting in lower operating costs in the long run. The project will be implemented using current and voltage sensing on individual solar cells in an array to provide performance feedback that determines if a cell has become shaded. Cloud shading will be taken in to account by programming and observing whether a whole group of solar cells have become shaded or just isolated cells. We will be adapting the car windshield cleaning mechanism for optimal cleaning (direction, speed, frequency). A soap/water mixture will be sprinkled during the cleaning cycle. Periodic cleaning will be programmed to occur in intervals based on the tradeoff between power consumption and cleaning effectiveness. For example, solar panels located in areas with high bird populations would require more frequent periodic cleaning. Our project will incorporate power electronics, microcontroller programming and control systems for motors.

The proposal our group has is of creating a board that will be able to teach students about logic circuits hands on. The project will consist of a board and different pieces that represent gates. The board will be used to plug in the pieces and provide power to the internal circuitry of the pieces. The pieces will have a gate and LEDs inside, which will be used to represent the logic at the different terminals.

By plugging in and combining gates, students will be able to see the actual effect on logic from the different combinations that they make. To add to it, we will add a truth table that can be used to represent inputs and outputs required, for example, for a class project or challenge. The board will be able to read the truth table and determine whether the logic the student has created is correct.

This board can act as a great learning source for students to understand the working of logic circuits. It can be helpful in teaching logic design to students in high schools who are interested in pursuing a degree in Electrical Engineering.

Please comment on whether the project is good enough to be approved, and if there are any suggestions.
