Abstract

‏ Solar panel collectors are one of the most common collectors available everywhere. One of the advantages of this type of collectors is their ease of construction and availability. Today, with the growing need for energy in the world, on the one hand, and on the other hand, due to the increasing environmental risks of fossil fuels, the need to replace existing energy with renewable energy is felt more. In this article, in addition to other articles that have worked on this topic, we want to examine the numerical analysis of the free heat transfer properties of flat panel solar collectors with different geometries using software and simulation. The results showed that the smaller the diameter of the fluid transfer pipe, the better in terms of efficiency because they lose less heat from the surface. The results also indicated that the amount of absorbed radiation in the upper plates of solar collectors is the highest value, i.e. 3740w/m2, and in the lower plates and the fluid transfer tube, its amount is equal to 1630w/m2.
