Pembangkit Listrik Tenaga Surya dapat menghasilkan energi yang tidak terbatas langsung diambil dari matahari. Sehingga sering dikatakan bersih dan ramah lingkungan. Permasalahan utama dalam pemanfaatan energi surya adalah output yang tidak stabil yang dapat merusak baterai maupun beban. Penelitian ini bertujuan untuk menganalisis daya panel surya yang digunakan untuk suplai daya beban maupun charging baterai dengan melakukan pengujian pada daya keluaran panel surya. Tahapan yang dilakukan adalah membuat trainer sistem pengujian dari panel surya, menetapkan variabel pengujian dan melakukan pengujian panel surya untuk menganalisa tegangan, arus, daya keluaran ke beban maupun baterai. Hasil menunjukkan bahwa intensitas yang semakin tinggi akan menghasilkan daya yang semakin besar, pada pengujian dengan beban lampu LED DC 200 Watt dihasilkan rata-rata daya maksimum yang di dapat pada sudut kemiringan panel surya 10 º sebesar 65.68 Watt dengan rata-rata intensitas cahaya tertinggi sebesar 47.73 klx, pada pengujian panel surya ketika digunakan sebagai suplai daya charging baterai sistem penerangan jalan umum dihasilkan rata-rata daya maksimum yang di dapat pada sudut kemiringan panel surya 10 º sebesar 58.20 Watt dengan rata-rata intensitas cahaya tertinggi sebesar 43.65 klx. Penurunan daya dipengaruhi oleh faktor-faktor yang menyebabkan terjadinya losses pada sistem dan kerugian lainnya seperti cuaca, debu pada permukaan panel suryaKata kunci : panel surya, pengujian, daya, intensitas cahaya. AbstractSolar Power Plants can produce unlimited energy directly taken from the sun. So it is often said to be clean and environmentally friendly. The main problem in the utilization of solar energy is unstable output that can damage the battery and load. This study aims to analyze the power of solar panels used for load power supply and battery charging by testing the output power of solar panels. The stages carried out are to create a test system trainer from solar panels, set test variables and test solar panels to analyze voltage, current, output power to the load and battery. The results show that the higher the intensity will produce more and more power, In the test with a DC LED light load of 200 Watts, the maximum average power that can be obtained at a solar panel inclination angle of 10 º of 65.68 Watts with the highest average light intensity of 47.73 klx, in solar panel tests when used as a charging power supply for batteries of public street lighting systems, the maximum average power can be obtained at a 10 º solar panel inclination angle of 58.20 Watts with the highest average light intensity of 43.65 klx. The decrease in power is influenced by factors that cause losses in the system and other losses such as weather, dust on the surface of solar panelsKeywords : solar panels, testing, power, light intensity.
