Abstract

Nowadays, the available commercial solar cells can convert solar energy into electrical energy with a yield of less than 30% and the conversion efficiency decreases inversely with the increase in temperature.
With the increase in population and industrialization rapidly, energy needs are also increasing. The depletion of limited fuels in the world continues rapidly. Renewable energy sources should be used for sustainable management of energy resources. Among renewable energy sources, solar energy is seen as a promising resource for the future. In recent years, Hybrid Photovoltaic Thermal (PVT) solar systems have become widespread worldwide to obtain electrical and thermal energy. While the solar panels on the market operate at low efficiency, the efficiency of converting solar energy to electrical energy decreases as the temperature increases. Hybrid PVT solar system has been developed to obtain thermal energy in addition to increasing electrical energy efficiency in solar panels. In this study, the efficiency of electrical and thermal energy in solar panels was investigated by using PVT-water and PVT-air in hybrid solar system. The compatibility between PVT-water and PVT-air systems has been discussed.

Abstract

Günümüzde kullanılan ticari güneş pilleri % 30’dan daha düşük bir verimle güneş enerjisini elektrik enerjisine dönüştürebilmekte ve dönüşüm verimi, sıcaklık artışı ile ters orantılı olarak azalmaktadır.
Hızla nüfus ve sanayileşme artışıyla enerji ihtiyaçları da artmaktadır. Dünyada kısıtlı olan yakıtların tükenmesi hızla devam etmektedir. Enerji kaynaklarının sürdürülebilir biçimde yönetilmesi için yenilenebilir enerji kaynaklarına başvurulmalıdır. Yenilenebilir enerji kaynakları arasında, güneş enerjisi geleceğe umut verici bir kaynak olarak görülmektedir. Hibrit Fotovoltaik Termal (PVT) solar sistemleri son yıllarda elektrik ve termal enerjisi elde edilmek için dünya çapında yaygınlaşmaya başlamıştır. Piyasada bulunan güneş panelleri düşük verimle çalışırken sıcaklık artıkça güneş enerjisinin elektrik enerjisine dönüştürme verimi de düşmektedir. Güneş panellerinde, elektrik enerjisi verimi arttırmanın yanı sıra termal enerjisi elde edilmek için hibrit PVT solar sistemi geliştirilmiştir. Bu çalışmada, hibrit solar sisteminde PVT-su ve PVT-hava kullanılarak güneş panellerinde elektrik ve termal enerjisinin verimleri araştırılmıştır. PVT-su ve PVT-hava sistemleri arasında karşılaştırma yapılarak uygunluğunu tartışılmıştır.
