production costs of solar energy

Hello community
Can you help me check it? Please

Another factor to consider is the decrease in solar energy production costs with respect to previous years. Believing that the great problem of solar energy is its cost, is not valid. Solar energy technology advances at the time it becomes cheaper. According to the U.S. Department of Energy, costs fell 61% from 2008 to 2016, it is estimated that by 2020 the reduction will be half. In India, for example, a country that bets heavily on solar energy, reached an unprecedented record. The price of Kilowatt per hour of solar energy reached 0.037 dollars equaling the price of traditional electricity. From my point of view, if engineering manages to develop materials that would lower production costs even more, what happened in India can could be expanded to other countries so that the energy transition could be given faster.
