Ground mounted PV systems offer several advantages over roof mounted systems:

1. Optimal orientation and tilt: Ground mounted systems can be installed at the ideal tilt angle and orientation to maximize solar energy production. This allows for better sunlight exposure throughout the day compared to the fixed angle of a roof.

2. Easy maintenance: Ground mounted systems are more accessible for maintenance and cleaning. Panels can be easily accessed without the need for climbing up roofs or using specialized equipment, making inspection, cleaning, and repairs simpler and safer.

3. Scalability: Ground mounted systems typically allow for greater scalability. There is more available space on the ground compared to the limited roof area, so you can install a larger solar array to meet your energy needs or expand the system in the future.

4. Reduced shading: Ground mounted systems are not subject to shading from nearby trees, buildings, or other obstructions that can impact the performance of roof mounted systems. This can result in higher overall energy production and efficiency.

5. Potential for dual use: Ground mounted systems can be installed in areas that are not suitable for other purposes, such as unused land or open fields. This allows for the efficient utilization of space and potentially generates income from the land while producing clean energy.

6. Flexibility in location: Ground mounted solar systems offer flexibility in terms of choosing the location for solar panel installation. They can be positioned in an optimal location on your property, taking into account factors like terrain, shading, and visual aesthetics.

However, it's important to note that ground mounted systems may require additional costs for site preparation, foundation construction, and wiring, depending on the location and ground conditions. Additionally, if you have limited available land or prefer the aesthetics of roof integrated systems, a roof mounted solution may still be a viable option.
