It'll probably also increase the cost of your home insurance. I'm not from the USA, but over here, accidents and acts of nature (e.g. a serious hailstorm) can damage your solar panels to the point they need replacing. If you bought them yourself, you usually add them to your home insurance, or purchase separate insurance just for the solar installation (which includes not just the panels).
Sometimes, getting it on a lease contract works out much cheaper, but the situation could be different in the USA -- for starters, as the article mentions, solar is quite subsidized in other countries (although in my case, I'm speaking about Europe), and startups / small businesses that deal with solar are also subsidized (except Spain, which recently changed in unpopular ways which I don't completely understand, yet). That creates a situation where companies that "lease" tend to try to be competitive with the already subsidized market. It sometimes turns out to be slightly more expensive, but the hassle-free nature of having "pros" maintain your installation and ask very few questions tends to be something people are interested in.
As an anecdote: a friend was doing some building work in his house and managed to damage a panel. They were replaced at no charge in less than a week. I was surprised because it was clearly his fault, but I guess they also want to keep their customers happy. Almost made me consider going with them if I bought my home.
