Lecturer Department of Electrical Engineering , Faculty of Engineering , added that the potential of solar energy to be optimized in terms of adding capacity for electricity supply in Indonesia . " Because Indonesia is in the region of the equator , which is getting quite a lot of sun exposure , " he said on Tuesday ( 29/4 ) .
Solar energy in the country, he said , very roduksi photovoltaic power models in order to increase the capacity of national power .
Actually , said Hermawan , photovoltaic utilization is set in the Regulation of the Board of Directors of PT PLN , but its applications are many obstacles . For one thing, photovoltaic components are still imported from abroad , and thus the cost to make it is still expensive .
" Many of the benefits of using solar power , which reduces electricity consumption from PLN and can reduce the temperature in the room , " he said .
Related to this , they said Hermawan , the government needs to do now is to encourage the growth of industry fotovoltoik . So this means the cost of solar energy utilization can be cheap . " Hopes , solar energy utilization can be optimized , " he added .
Previous growth in electricity consumption per year in Central Java continues to increase to 10 percent . If it is not offset by the manufacture or creation of a new generation of renewable energy , in Central Java in 2017 electricity crisis that has the potential to rolling blackouts .
