The uses of lorentzian peak function for solar energy projection at Badung Regency, Bali Province.

This research aims to prepare daily solar energy data for the government and the community in Badung Regency, Bali Province. This study uses primary data from Lutron SPM-1116SD solar power meter at two locations, i.e., Buduk Village, Mengwi District, and Bongkasa Pertiwi Village, Abiansemal District. These two locations are in Badung Regency, Bali Province. We collected the primary data collection from September 2020 to March 2021 when the sun moved from the equator to the December equinox and returned to the equator. First, we put both solar power meters on the flat horizontal surface. Then, the primary data from both solar power meters are selected every month and processed to obtain the solar energy value. Next, we perform data fitting with the Lorentzian Peak Function (LPF) and calculate the solar energy value. After that, we compare the solar energy value of the LPF with the primary data value using the statistics of Two-Samples of Kolmogorov-Smirnov. At the 0.05 level, there is no significant difference between the solar energy data value compared with the solar energy LPF fitting value. Thus the LPF can project the solar energy value from September to March at Badung Regency, Bali Province. [ABSTRACT FROM AUTHOR]
