Rainwater harvesting in solar power plant

Abstract

Information about rainwater harvesting was given and its applicability in solar power plants was evaluated with scenarios. Rainwater harvesting is done on solar panels, and it is aimed at using the collected water for panel cleaning. For this purpose, the annual precipitation falling on the panel areas was calculated by choosing the solar power plant with the largest area in Turkey. As a result of the study, how much of the water consumption of the solar power plants can be met from rainwater was evaluated with 3 different scenarios. In the Base Scenario, the coverage rate for the amount of water required for cleaning is approximately 76% if cleaning is carried out daily. This rate drops to 59% in Scenario 1, 42% in Scenario 2 and 29% in Scenario 3.

Güneş enerjisi santrallerinde yağmur suyu hasadı

Öz

Bu çalışmada yağmur suyu hasadı hakkında bilgi verilerek, güneş enerjisi santrallerinde uygulanabilirliği senaryolar eşliğinde değerlendirilmiştir. Yağmur suyu hasadının güneş panelleri üzerinde yapılarak, toplanan suyun panel temizliğinde kullanılması hedeflenmektedir. Bu amaçla Türkiye’deki en büyük alana sahip güneş enerjisi santrali seçilerek panel alanlarına düşen yıllık yağış miktarı hesaplanmıştır. Çalışma sonucunda güneş enerjisi santrallerinin su tüketiminin ne kadarının yağmur suyundan karşılanabileceği 3 farklı senaryo eşliğinde değerlendirilmiştir. Baz Senaryoda temizlik için gereken su miktarını karşılama oranı her gün temizlik yapılması durumunda yaklaşık %76 oranındadır. Bu oran Senaryo1’de %59, Senaryo 2’de %42 ve Senaryo 3’de %29’ye düşmektedir.
