Testing of Solar-Wind Energy Hybrid System Small Scale

Abstract

Electrical energy sources are currently declining so that renewable energy is environmentally friendly as an alternative energy source. This paper aims to test the charging of a hybrid system based on the prototype of a hybrid solar power plant and wind/wind energy as an alternative energy source. The method of carrying out the activity is carried out by charging the system to the accumulator when the wind speed is capable of turning the turbine and filling the accumulator and at the wind speed that is not able to fill the accumulator with a hybrid system. This research was conducted at Akarena Beach Makassar in the dry season. The results showed that testing of hybrid generators with parallel solar panels totalling 4 pieces @ 50 Watt peak (Wp) to 200 Watt peak (Wp) was able to charge 4 accumulators connected parallel @ 18 Ah or 72 Ah for ± 10 hours in sunny conditions with a charging current of 7.39 Amperes at wind speeds of 1-3 m/s and at wind speeds of 5-7 m/s the magnitude of the charging current reaches 8.02 Amperes at 15:00 to 17:00, thus, the charging time becomes faster after the turbine works with wind speeds above 5 m/sec.
