SCAT is an Arduino-powered solar panel system that tracks the brightest light and automatically removes dust to improve energy generation.
Dust, sand, and debris collect on solar panels and block sunlight from reaching solar cells. This reduces electricity generation and affects the overall efficiency of solar installations.
SCAT solves this problem by combining solar tracking and automated cleaning. It helps the panel face the brightest sunlight while keeping its surface clear from dust.
LDR sensors detect and follow the strongest source of sunlight throughout the day.
An anti-static wiper automatically removes dust and debris from the panel surface.
Support more efficient and lower-maintenance solar systems over the long term.
Four components working together to keep your panel pointed at the sun and free of dust.
LDR (Light Dependent Resistor) sensors detect the brightest source of light in the environment.
Arduino Uno processes the sensor inputs and calculates the optimal panel orientation in real time.
A servo motor physically rotates the solar panel to face the detected brightest light source.
The anti-static dust cleaner sweeps across the panel surface, removing dust and debris automatically.
SCAT is a functional demonstration model that combines solar tracking, automated cleaning, Arduino control, sensors, and servo-driven movement.
Every component plays a specific role in making SCAT track smarter and stay cleaner.
The brain of the system. Reads sensor data and sends control signals to the servo motor and cleaner.
MicrocontrollerProvides precise rotational movement to orient the solar panel toward the detected light source.
ActuatorLight Dependent Resistors measure ambient light intensity and guide the tracking direction.
SensorConverts tracked sunlight into usable electrical energy. Kept clean for maximum output efficiency.
Energy SourceSweeps dust and debris off the panel surface without creating charge buildup that could cause static damage.
Cleaning UnitFlexible wire connections linking all electronic components on the breadboard and circuit assembly.
WiringA precise breakdown of every hardware and software element used in the SCAT prototype.
Real voltage measurements comparing a fixed panel against the SCAT system throughout the day.
Comparing fixed panel (no cleaner) vs. SCAT solar tracker with cleaner
Increase in power generation observed with the SCAT system compared to a fixed, uncleaned panel.
Average voltage observed across different test sites
Usable solar output observed between approximately 61% and 71% during the day across test locations.
Results are based on prototype testing under observed conditions. Performance may vary depending on sunlight intensity, dust accumulation, weather, location, and solar panel specifications.
SCAT combines solar tracking with automatic cleaning to improve renewable-energy generation, reduce manual maintenance, and support longer-lasting solar installations. Continued testing under different environmental conditions can further improve the system.
