5-kW Solar Payback Time : 6 Years
Investment Return (IRR) : 24.4
Back in 2015, Hawaii became the first state to set a 100 renewable energy goal. That’s a huge deal! And the Aloha State needs it, too—most of their electricity now comes from burning imported fossil fuels. That imported oil and gas costs a ton, which is why solar doesn’t need big incentives to be successful here. Unfortunately, the state’s main utility, HECO, has a new net-metering-lite way of paying for solar that might prove to be a bad deal in the near future. Still, the electricity prices here are super high and the state has a good tax credit, so a solar investment in Hawaii is just about the best in the nation.
