Solar panels on a ballasted mount are attached to the roof at an angle several feet or meters above the roof. Ballasted mounts are efficient because they do not penetrate the roof and receive more direct sunlight. Because this design makes them more vulnerable to being blown away, however, they do not work well in windy climates.   On the whole, ballasted systems tend to be the cheapest mounting option. They can cost between $50-100 USD per panel. Ballasted systems generally cover the whole roof, which can make maintenance or remodeling hard. Solar panels on a mechanically-attached mount are attached tightly to the roof at a slight or no angle. Because mechanically-attached mounts are mounted to the roof beams, they fare well in harsh weather. They also take up less space and are ideal if you need access to your roof often.  Because mechanically-attached mounts are smaller, they're usually easier on the roof. Mechanically-attached mounts may cost between $75-125 per panel. Hybrid mounts are attached to the roof like mechanically-attached mounts but may be slightly raised or angled like ballasted mounts. This keeps them secure to the roof while receiving more direct sunlight like ballasted mounts. Fixed mounts follow the sun throughout the day.  This orients their panel positioning to absorb as much sunlight as possible. If your solar panel is on the ground and receives some shade each day, fixed mounts can help your system convert more energy. Fixed mounts can cost between $160-200 per panel.
