Comparative Analysis with PVGIS and PVsyst for Solar Energy Production in Bahşılı Region of Kırıkkale

Abstract

This study examines the energy production potential of a fixed-axis photovoltaic (PV) system in the Bahşılı region of Kırıkkale, using PVGIS and PVsyst simulation software. The research highlights the increasing significance of renewable energy in Turkey, particularly in light of the country’s commitment to achieving net-zero emissions by 2053. Solar tracking systems have been identified as a promising technology for enhancing solar energy efficiency, yet their high initial costs and maintenance requirements present challenges. Through comparative simulations, the study finds that PVsyst estimates annual energy production at 33.179 GWh, approximately 30% higher than the 25.392 GWh predicted by PVGIS. This discrepancy is attributed to methodological differences, with PVsyst offering more detailed component analysis and loss evaluations. The research underscores the importance of simulation accuracy in project planning and emphasizes the potential benefits of solar tracking systems despite their limitations. Future work will focus on incorporating solar tracking systems into the analysis and validating simulation results with real-world field data. The findings contribute to more effective solar energy project planning and development of sustainable energy solutions in Turkey.

Kırıkkale Bahşılı Bölgesinde Güneş Enerjisi Üretiminin PVGIS ve PVsyst ile Karşılaştırmalı Analizi

Öz

Bu çalışma, Kırıkkale’nin Bahşılı bölgesinde sabit eksenli bir fotovoltaik (PV) sistemin enerji üretim potansiyelini PVGIS ve PVsyst simülasyon yazılımlarını kullanarak incelemektedir. Araştırma, Türkiye’nin 2053 yılına kadar net sıfır emisyon hedefini gerçekleştirme taahhüdü doğrultusunda yenilenebilir enerjinin artan önemini vurgulamaktadır. Güneş takip sistemleri, güneş enerjisi verimliliğini artırmada umut verici bir teknoloji olarak görülmekte, ancak yüksek başlangıç maliyetleri ve bakım gereksinimleri bazı zorluklar yaratmaktadır. Karşılaştırmalı simülasyonlar sonucunda, PVsyst’in yıllık enerji üretimini 33,179 GWh olarak tahmin ettiği, PVGIS’in ise 25,392 GWh olarak öngördüğü belirlenmiştir. PVsyst’in tahmininin yaklaşık %30 daha yüksek olmasının, metodolojik farklılıklardan kaynaklandığı; özellikle PVsyst’in daha ayrıntılı bileşen analizi ve kayıp değerlendirmesi sunduğu tespit edilmiştir. Araştırma, proje planlamasında simülasyon doğruluğunun önemini vurgularken, sınırlamalarına rağmen güneş takip sistemlerinin potansiyel faydalarına dikkat çekmektedir. Gelecek çalışmalarda, güneş takip sistemleri analize dahil edilerek simülasyon sonuçlarının saha verileriyle doğrulanması hedeflenmektedir. Bulgular, Türkiye’de daha etkili güneş enerjisi projeleri planlamaya ve sürdürülebilir enerji çözümleri geliştirmeye katkı sağlamaktadır.
