Problem Statement: The solar industry struggles with the inefficiency and suboptimal performance of solar panels due to the accumulation of dust, dirt, and debris. The current manual cleaning methods used for solar panel maintenance are time-consuming, costly, and potentially risky for workers. These methods often result in inconsistent cleaning coverage, leading to reduced energy output and decreased profitability of solar installations. There is a need for an efficient, cost-effective, and safe solution to clean solar panels regularly, ensuring maximum energy generation and prolonging the lifespan of the panels.

Efficiency Gains: Research has shown that dirty solar panels can experience a significant reduction in efficiency. According to studies conducted by the National Renewable Energy Laboratory (NREL), dirty solar panels can experience a loss in energy output ranging from 7% to 25%, depending on the accumulation of dust and dirt. Regular cleaning with robots helps maintain optimal performance, ensuring higher energy production levels.

Cost Savings: The use of solar panel cleaning robots can lead to substantial cost savings over time. A study published in the International Journal of Automation and Smart Technology found that using a robot for cleaning solar panels reduced the cost by up to 40% compared to manual cleaning methods. The savings result from reduced labor costs, increased efficiency, and minimized downtime.

Increased Energy Generation: Clean solar panels generate more electricity compared to dirty panels. A case study published by the University of California, San Diego (UCSD) highlighted that regular cleaning of solar panels led to an increase in energy production by up to 12%.

Safety Improvements: Manual cleaning of solar panels can be a hazardous task, especially when working at heights or on large installations. Using robots for cleaning eliminates the need for workers to physically access the panels, reducing the risk of accidents and injuries.

Environmental Impact: By maximizing the efficiency of solar panels, cleaning robots contribute to the reduction of greenhouse gas emissions and reliance on non-renewable energy sources. A study conducted by SolarPower Europe estimated that regular cleaning of solar panels could increase global solar energy production by up to 5%. This increase in clean energy generation helps mitigate climate change and promote sustainable development.

Proposed Design: The bot consists of brush assembly along with the gear boxes connected to the conveyor belt to give forward motion. There are two pipes supplying water, one is at the front to wet the panel while other is at the back of the brush to clean it. A motor of 2800 rpm is used whose speed is reduced to 300 rpm through the gearbox. The bot parts are 3D printed. Gears are also 3D printed with ABS. Aluminum profile is used to provide support. Spiral brush has been designed to ensure proper cleaning.
