This study explores harnessing rainwater hydroelectric turbine to convert the kinetic energy the negative impacts of conventional energy rainwater harvesting system with a Pelton wheel turbine, aiming to maximize the generator’s output at a S-meter elevation by optimizing the gear ratio. The objectives included determining the optimal gear ratio. comparing the output paramedic. rainwater collection tank with and without a bell siphon, and assessing the economy Viability of both setups. The study computed a suitable gear ratio of 53:20 for the system but further investigation led the researchers to test additional gear ratios-52:20, 53:24, 54:20, and 55:20to analyze the impact of different configurations. Data was gathered by simulating the rainwater harvesting system. The results showed that a tank without a bell siphon did not rotate at the computed optimal gear ratio, nor did it rotate at the highest gear ratio of 55:20. However, this setup only generated minimal output, producing I.52V, 0.14A, and 0.22W with an efficiency of 3.29%, using a 1:1 (20:20) gear ratio and a load of a 3.8V, 0.3A light bulb. In contrast, the tank with a bell siphon generated varying outputs, with the 55:20 ratio delivering the highest output voltage of 9.10V under no-load conditions. When tested with a load of two 6V, 8W bulbs, the system produced 7.59V, 0.48A. and 3.65W, with an efficiency of 54.72%. Economically, the system with a bell siphon had a payback period of 267 years, which was significantly lower than the rainwater collection tank without a bell siphon, which could take up to 4,366.8 years to recover its costs, However, despite the shorter payback period, the system with the bell siphon may still not he viable in the long term. The researchers recommend further investigation to make the rainwater harvesting system more efficient and economically viable.
