ABSTRACT. It is important to research, develop and disseminate new and renewable energy sources instead of fossil fuels such as fossil fuels because of the energy demands of today. The need for new and renewable energy sources and the efforts to efficiently use these resources have also been accelerated. In this study which was made for the same purpose, in the study with the solar energy, in the Edirne related climate conditions for water heating, one is a closed system with fixed angle and natural circulation, the other is the closed system consisting of closed system with photo-controlled unit. Two experimental setups were designed. In these experimental setups, instantaneous, daily and average efficiency values for both systems were determined by using two standard flatplate collectors of the same type, copper pipe, copper wing, flat plate and single glazed with equal collector area, during September, moving and follow-up system (following the sun with Photo-controlled Unit).
Introduction. In many applications made from solar energy, the conditions of operation and operation of the systems to be designed and applied are gaining importance in response to the question of how long and in which way the solar rays can be used, in consideration of the climate conditions to be applied. In order to be able to decide on applicable systems or systems that may be suitable for Edirne province climatic conditions, a "Closed System with Fixed Angle and Natural Circulation" which is a very common system applied in Edirne. Other that seem to have a high initial investment cost and thus are not very common to implement "Closed System with Moving and Follow-up system with Photo-Controlled Unit and Pumped Circulation System", these systems, which are called in September 2015 climate conditions, 1. System (First System): closed system with fixed angle natural circulation; 2. System (Second System): closed system with moving and follow-up system (following the sun with Photo-controlled Unit) and pumped circulation system. Materials If the two different systems in the experimental setup used in this study and the technical specifications of the elements forming these systems are explained in detail: 1) Closed system with fixed angle natural circulation: this system, which is called as (First System) 1st. System in the experimental setup; 2 pieces of 1930x930x85 mm size, 8 copper pipes, copper winged semiclective surface, monobloc polyurethane insulated flat-plate collector; The Authors.
