Hot water system based on the hybrid solar collector photovoltaic/thermal PVT

there are some elements that are the basis of most solar heating of water: the sensor (s), storage tank, heat transfer medium and interconnecting tubes. The hybrid solar collector PVT captures sunlight and converts it into heat which is transferred to the storage tank by means of a fluid such as water or air. An expansion vessel is used in closed to accommodate slight variations in volume that occur when the fluid is heated and expands, a heat exchanger is required to transfer heat from the manifold with water to exit the system faucet. In this section we will study and will present the energy behavior of a hybrid photovoltaic thermal solar PVT in a complete energy system (Enforceability of heating water for habitat in southern Algeria) and is very important right now especially in the Sahara and semi arid (Ghardaia).
