Abstract

Improving solar power plant performance is considered quite important for existing and prospective users of rooftop solar power plants in Indonesia due to its unattractive economic value. One of the efforts to optimize the performance is the application of an additional cooling system on the plant's photovoltaic module. This study aimed to determine the effectiveness of temperature reduction of the applied cooling system on solar panel productivity. The research was performed on the existing rooftop solar power plant with a capacity of 3 kWp, located in Depok City with coordinates of 6°38'03.40" South Latitude and 106°82'03.49" East Longitude.

The results showed that the additional water cooling system with a closed-loop pumping method on the installed solar module’s entire surface could improve the rooftop solar power plant performance with an average production increase of 15.7% in 7 days of study. Meanwhile, from an economic point of view, this cooling system installation payback period was 2 years.
