Günümüzde enerji ihtiyacımız giderek artmaktadır ve enerji üretimi için birçok sistem geliştirilmiştir. Çevreyi korumak adına temiz ve yenilenebilir enerji giderek önem kazanmıştır. Bu sistemlerden en çok kullanılanı güneş enerjisinden elektrik enerjisi üretmemizi sağlayan fotovoltaik (PV) sistemleridir. PV sistemleri zamanla gelişerek, elektrik üretiminin yanında sistemde oluşan termal enerjiyi bir ya da daha fazla akışkana aktararak aynı sistemden hem elektrik hem de termal kazanım elde etmeye yarayan, PV/T sistemleri geliştirilmiştir.
Bu çalışmada hava ve su bazlı bir PV/T sisteminde güneş ışığını karşılayan ilk parçası olan cam kapak özelliklerinin elektrik üretimini nasıl etkilediği araştırılmıştır. Deney düzeneği Konya şehrinde kurulmuş ve benzer açık hava koşullarında karşılaştırmalar yapılmıştır.

Our energy needs are increasing day by day and many systems have been developed for energy production. Clean and renewable energy has become increasingly important to protect the environment. The most used of these systems are photovoltaic (PV) systems that enable us to generate electrical energy from solar energy. PV systems have been developed over time, and besides electricity production, PV/T systems have been developed to transfer both the thermal energy generated in the system to one or more fluids and to obtain both electricity and thermal gain from the same system. In Turkey, we have a great potential of solar power. And our aim is using this clean energy and made it more efficient.
In this study, it has been researched how the glass cover properties, which are the first part of the PV/T system that meet the sunlight, affect electricity production and thermal gain. The experimental setup was established in Konya city in Turkey and comparisons were made under similar open air conditions. There were three types of glasses been examined. First glass has four mm of thickness and it is not coated. Second experiment glass was called low-e glass, it was also has four mm thickness and it has a low-e coating. Third glass was a air hollowed double glass which mean is two glasses combined with a twelve mm air hollow. These two glasses both have four mm thickness. We were expecting decrease in electrical gain but increase on thermal gain. The glasses were mounted and demounted on this order and several experiments were been made. For the study’s results section, three days with the most similar weather conditions -in terms of wind, outdoor weather temperature- were selected and comparisions on electricity production and thermal gains made for each days. This system can be used in hotels, dormitories and such.
