Abstract : Over the past decade, India has witnessed a significant increase in the share of renewable energy sources in its
energy mix, rising from 13.2% in 2010 to 24.8% in 2020, driven by governmental policies like the National Solar Mission
and the Renewable Purchase Obligation (RPO). This growth has been further fueled by diminishing fossil fuel reserves,
rising fuel prices, and global emissions regulations. Consequently, there has been a notable surge in the adoption of solar
evacuated tube collector-based domestic water heating systems, with installations in India escalating from 1.8 million square
meters in 2015 to 3.2 million square meters in 2020, reflecting increased awareness and the tangible benefits of renewable
energy technologies. However, challenges persist, especially in densely populated urban areas with limited installation space
due to rapid urbanization. To address this, the study proposes reducing the collector area by varying evacuated tube
diameters. Comparative analysis between evacuated tube collectors and flat plate solar water heaters aims to introduce a dual
absorber solar water heater capable of harnessing direct and diffused solar radiation, enhancing hot water generation and
system efficiency. Findings suggest that 48mm diameter and 1800mm length tubes are optimal for evacuated tube models,
while a 4m2 collector area proves excessive for a 150-litre solar water heater. Theoretical validation using MATLAB aligns
with experimental results. A dual absorber-based solar water heater is proposed, potentially reducing collector area by
approximately 30%. Further research is recommended to refine the capacity and efficiency of this proposed model.
