Although solar panels offer many benefits, there are some drawbacks as well, including: ● Initial cost. Although solar panels prices have dropped in cost by 80% in the past decade, it is still expensive to install them. Systems cost $15,000 to $26,000. ● Not aesthetically appealing. Solar panels look clunky and interfere with the beauty of the roof.  ● Inactive hours. At nighttime, solar panels are unproductive and don’t generate energy. They are also less productive in shaded or cloudy areas.  ● They don’t work on every roof. Some roofs can’t handle the weight of solar panels. Other roofs don’t get enough sunshine. To accommodate solar panels, roofs must have the appropriate angle, shape, space, and amount of sun.
