The contribution of electrical energy is the sustains life, especially at night activities. farmer groups in Marsudi Luhur in Pirak Mertosutan Godean Yogyakarta are ettawa goat breeders, who using Solar Home System for electrical at night activities. This research was conducted to determine the performance of the solar home system installation at Marsudi Luhur farmer group which starts from 08:00 until 16:00 WIB. The Instllation on the SHS can produce 12.70 V, 1.80 Ampere, and 22.91 Watt. The status of the battery battery in the Solar Home System installation has a charging condition with the voltage value in Solar Charge Controller greater than the battery voltage with an estimated charging time of 50 hours. The measurement results for voltage harmonics exceed) regulatory limit the IEEE 519-2014 (THD V at solar home system installations, which are 60.03% in THD V-phase and 36.80% in THD V-neutral. For the current harmonic value (THD I) it does not exceed the limit of 0.13% in THD I-phase or THD I-neutral. The efficiency value generated by solar home systems in farmer group is 65.14%.
