Design and Study on Small Solar Energy Photovoltaic Hot Water System

A better structure is obtained in this paper by design calculations of the single PV/T components, the fin height of the heat collector is between 10 mm~20 mm and fin space between 20~40 mm which makes flow resistance reduced effectively in the heat collector and the heat transfer effect better. A small solar energy photovoltaic and thermal household hybrid system is designed, which is suitable in Shanghai. The capacity of water tank which benefits the overall thermoelectric efficiency is determined by calculating the flow characteristic of the home PV/T systems. In addition, the pipeline layout is identified through the hydraulic balance calculations, which shows that the hydraulic imbalance of each branch is 1.14%, which meets the engineering requirements.
