Why has the solar shingles market not grown much faster?

[admin]

Solar shingles have been around much longer than many think. While Tesla’s entry into the market made it more popular, solar shingles had been commercialized sometime around 2005 and even the chemicals and materials major Dow had launched its own solar shingles way back in 2009.

Solar shingles appear like a good fit for many rooftops especially in developed economies which can afford the higher cost of shingles for the aesthetic advantage they have over solar panels.

But somehow it does not seem to have taken off.

What could be the reasons behind the shingles’ slow take off, and what can be done to accelerate its adoption?
