Hawaii imports energy, which costs three times higher than the use of a Hawaii Solar Power System. Hawaii makes the first state to reach the grid parity for the photovoltaic. It is a tropical location where there is enough sunshine throughout the year and this is tapped to the storage panel systems. According to a recent study, Oahu grid provides 500 megawatts of power and coupling it with 100 megawatts of solar generated power reduces the pollution levels.
This is possible through the reduction of the burning of more than two and a half million barrels of low sulfur fuel and a hundred and thirty tons of coal annually in the state. There is a renewable portfolio standard that aims to make the use of renewable energy to forty percent by the year 2030 and connect majority of the population with the photovoltaic grid. According to a recent estimate, a typical solar system will pay the cost of installation in four years and returns high profits in the four years of its life.
