If the owner desires a photovoltaic array, but wants to use the generated electricity, this system would store the energy for them to use. For a house located in a climate with a lower cooling load, the savings would be correspondingly lower. However, using the system for heating and heat storage is a possibility for cold climates. 5. CONCLUSION
1. Introduction One of the most widespread technologies of renewable energy generation is the use of photovoltaic (PV) systems which convert sunlight to into usable electrical energy , .
Proper cooling can improve the electrical efficiency, and decrease the rate of cell degradation with time, resulting in maximisation of the life span of photovoltaic modules. The excessive heat removed by the cooling system can be used in domestic, commercial or industrial applications.
Liquid cooling of photovoltaic panels is a very efficient method and achieves satisfactory results. Regardless of the cooling system size or the water temperature, this method of cooling always improves the electrical efficiency of PV modules. The operating principle of this cooling type is based on water use.
Therefore, our design does utilize a method for storing energy for cooling as needed. The combined air conditioning and thermal storage system is intended as a technology to increase the effectiveness of solar photovoltaic energy use.
The cooling system can be regulated as per the environmental conditions which can ensure optimal PV operating temperature to achieve maximum efficiency. Different options such as air-based and water-based cooling can be tailored according to specific application requirements.
