As Merriam-Webster tells us, inflation is defined as:
"a continuing rise in the general price level usually attributed to an increase in the volume of money and credit relative to available goods and services."
I know, I know -- not exactly the kind of thing you want to be reading on a Friday. But before your eyes glaze over, take a look at the following picture, via our friends over at Clean Power Finance.
As you can see, we've got two situations. One in which we don't install a solar energy system (shown by the "pre-solar" blue dotted line) and one in which we do install a solar energy system (shown by the "post-solar" green line). After installing solar panels, our annual electric bill goes from about $1,000 to, say, around $450. Our new solar energy system is meeting more than half our annual electricity needs -- pretty cool, huh?

Now, you might have noticed that, in year 13, the gap between the pre-solar line and the post-solar line is wider than it was in the first year -- and the gap is wider still in year twenty-five. In other words, the amount of money solar power saves us increases over time. What's going on here?
