Roof Mounted solar photovoltaic modules have the advantages of low cost and height, generally above nearby obstacles and harms way.  This economical method utilizes the trusses of the structure to secure the modules.  However the roof is not ideal in every case.  Perhaps there are significant obstructions to sun exposure on the roof, such as nearby trees, buildings, or terrain.  Or the roof itself has obstructions that will interfere with full sun exposure, such as sky lights and chimneys.  Remember even the shadow from a deciduous tree limb in winter is substantial enough to reduce the output of a solar module.  In these cases a ground mount might be the preferred option.  Advantages here include ease of snow removal and variety in the location of the array.  We typically work with an excavator and pour concrete to secure the mount which increase the total cost of the system. Electric code also requires a fence surrounding the array to restrict access. Give Dan a call to discuss ideal installation for your solar electric system.
