Trent Nelson | The Salt Lake Tribune Solar panels are installed on the roof of a Farmington home. Based on the first quarter, Utah is on track to have more rooftop solar installed in 2016 than in all previous years combined. Adopters say that's because, in the last few months, it has become possible to replace your entire power bill with solar panels ó and with state and federal tax credits in place for at least the next year, it still is possible to get the government to refund you almost half the cost.
