DOW is not usually a name that comes up when discussing sustainability and clean technology.
That may change now that the company has start selling and installing their first rooftop solar shingles. This modular PV system, dubbed ‘Powerhouse’ (oh, I get it) doesn’t just mount on your roof, it IS your roof. These individual units overlap just like asphalt shingles and string together in a circuit, giving you much more flexibility in fitting your roof’s shape and size.
What are the pros of a system like this?
-They are flush with the rest of your roof
One of the main complaints about roof mounted PV systems is that they literally stand out, detracting from the architectural aesthetic of a home
-No mounting brackets
The singles attach with nails, just like normal roofing shingles. Also, no mounting brackets means less equipment to buy!
You can install as many or as few as you like, or your budget will allow
-No adjusting the angle
Solar installers typically put panels in at the optimum angle for electricity production, which varies by location. This angle doesn’t always match your roof, so there could be decreased efficiency, especially on steep roofs
-Solar panels are less effective when hot
DOW may have a way of addressing this, but without air moving over AND under the panels, they might heat up more, making them less efficient.
I wasn’t able to find any pricing information per shingle, but here is a good infographic from DOW explain the total costs of ownership:
