Since the world is promoting green energy, more and more ideas have come out. During the State of Union, President Obama announced a lesser-known photovoltaic energy source which looks like roofing shingles, but can power houses more cheaply than the regular solar panels. The company, LUMA, which produces the solar shingles, states that one shingle cannot produce a lot of power. However, hundreds of square feet of them can produce between 2400 and 8640 watts of electricity. The solar shingles look almost like the regular roofing shingles and cost less than regular solar panels. Although that the solar shingles are not cheap, it is an available solar product for most people, and enable us to have a cleaner tomorrow!
