| description |
Photovoltaic (PV) systems can be used in a wide range of applications because of a significant drop in cost over the last ten years for PV modules. Because PV solar panels are low-cost and have a simple design that just requires sunshine to work, they can be used to power loads that are directly linked to PV panels. Because of this, it is a more alluring option for applications involving water heating.
In this work, experimental evaluation has been done for photovoltaic-direct-powered solar domestic hot water systems on 3/Jan./2024 a clear, sunny day. When evaluating performance, the value of power generated by PV panels is crucial. As solar radiation rises, its value rises as well. The PV heater tank's inside water temperature reached a maximum of 83.50 °C. A family of three members used 131 liters of water at a flow rate of 2 L/m. The maximum power delivered to the heating element was 1188 W, and the maximum power generated by PV panels was 1240 W. Based on the specifications of the 1500W heating element utilized, about 312W of electricity is lost during operation. Calculations revealed that the system's electrical efficiency was 22.3%. The system required 8.6 years of payback time to recoup its initial expenditure. Based on these results, it is advised to utilize a direct- connected photovoltaic water heater system (DPVWH) in cold weather because of its ease of use and efficiency, as it is a technology that operates during daylight hours.
