Homeowner''s Guide to Going Solar | Department of Energy

Solar panels are built to work in all climates, but in some cases, rooftops may not be suitable for solar systems due to age or tree cover. If there are trees near your home that create excessive shade on your roof, rooftop panels may not be the most ideal option. The size, shape, and slope of your roof are also important factors to consider.

In a new development, besides mounting on the roof top, the PV modules or panels could in a creative, aesthetically-pleasing manner be integrated into the building facade (this form of PV is commonly known as Building Integrated Photovoltaic or BIPV in short). This could be on any part of the roof or external walls
