The sun is shining on the tax credit for solar power but this federal tax credit that lightens your tax burden significantly starts sunsetting in 2020.

The good news is that the cost of solar panels and equipment is dropping, down about 6.5% in 2018, and putting in solar panels can cut your utility bills by a lot. The bad news is the upfront cost isn't cheap — an average of $13,188 in 2018, according to EnergySage, a marketplace for solar equipment.
