They’re sleek, sexy, and absolutely shame the Joneses in roof-coolness factor. But, a half decade after their introduction, the question that’s still going begging is: do they work half as well as they look?

You might have ended up here because most of the information out there has Dow Chemical’s fingerprints all over it. They, along with CertainTeed, are the two major players in the still-nascent solar shingle niche.
Ultimately, it will be up to you to decide if the style factor is worth the additional risk over solar panels. Hang out for a few minutes on Dow’s savings calculator and you’ll be scratching your head, “My God, they practically pay for themselves three times over!” Here’s why they’re still risky, no matter what the smooth talkers tell you:
They’re advertised as equally durable to their traditional counterparts, but their reliability in paying for themselves is dependent on their durability over the next 25 years, and they’ve only proven themselves capable of a solid 5.
For the price that it takes power your entire home with traditional panels to , you’ll experience (at best) a 60 to 70 percent reduction in your energy bill with shingles.
Yes, they’re no longer the 60-hour nightmare they used to be, but there are far fewer installers that know how to do solar shingles properly. You’ll likely pay more to find someone to do this fidgety, relatively uncommon task.
These things generate heat, and if your roof isn’t designed to withstand higher levels, you’re in trouble. Some solar shingles require extensive drilling all the way through the roof, which can affect installation cost depending on your design.
