“…A controller is used to control the valve as well as to restrict and enable the movement of water. The Arduino controls the wiping motor to remove the dust from the panel if the voltage drops as a result of dust particles accumulating there [13]. To further improve efficiency, it can be executed by cleansing the solar panel with a water or chemical-based mixture.…”

The adoption of green energy sources like solar power continues to rise due to price hikes for electricity and have implications about the environmental effects of fossil fuels. Natural occurrences, such as the build-up of dust on installed photovoltaic panels' surfaces, tend to lower their electrical output, which in turn lowers their efficiency. Cleaning products are hence essential for increasing solar panels' effectiveness. Cleaning panels by hand is pricey and ineffective. A prototype of solar panel cleansing mechanism has been presented in this paper and the enhanced output power after its implementation has been recorded. This strategy seeks to increase the effectiveness of by removing any kind of dust on solar cells. The proposed work includes a cloud server that uses the internet of things (IoT) to provide global live status monitoring. It ca n be entirely automated by the assistance of robotics and the Internet of Things. A mechanised cleaning system is more effective and uses less water. The unit can function both directly and electronically owing to sensors, microcontrollers, and other components.

The present work aims to investigate thermal performance of a solar flat plate collector using water and Cu-MWCNTs nanoparticle-based hybrid nanofluid both experimentally and numerically. X-Ray diffraction, FESEM with EDAX mapping were performed to characterize nanoparticles. The experimental setup was developed for thermal performance of FPC varying flow rates (0.5, 1.0, 1.5 lpm), inclination angle (25°, 30°, 35°, 40°, 45°), volume concentration (0 %, 0.1 %, 0.2 %, 0.3 %, 0.4 %) and intensity (400 W/m 2 ). The 3D numerical model having similar geometry as of actual flat plate collector was modeled using Fluents 15.0. The SST turbulence model was used to capture the chaotic changes in the velocity, temperature, and pressure fields. The experimental findings revealed 79.74% improvement in instantaneous efficiency at 0.4% vol., 1.5 lpm, 45° inclination angle, and 400 W/m 2 intensity. The maximum deviation between the experimental and numerically calculated outlet and inlet temperature difference (ΔT) was 3.5% using a hybrid nanofluid.When numerical data are compared, instantaneous efficiency and heat gain both deviate by 2.8% and 2.9% from experimental values. Because of the numerical simulation analysis, it is possible to observe the temperature and flow pattern in flat plate collectors using nanofluids under a set of operating conditions, which would not be possible without the simulation.
