How to draw an elevated roof on the base roof?

"Roof on roof" in solar design refers to the concept of installing solar panels on a secondary or elevated roof structure that is built above the primary roof of a building. This approach is often used in specific scenarios where the primary roof is not ideal for direct solar panel installation.

Key Points of "Roof on Roof" in Solar Design:

  1. Secondary Structure:

    • A secondary, often smaller, roof is constructed on top of the existing roof to serve as the mounting surface for solar panels.

  2. Improved Orientation and Tilt:

    • The secondary roof can be designed with an optimal orientation and tilt angle to maximize solar energy capture, which may not be possible with the original roof.

  3. Avoiding Obstacles:

    • This design can help avoid obstacles such as skylights, vents, or other rooftop equipment that might interfere with panel placement on the main roof.

  4. Enhanced Ventilation:

    • The space between the primary roof and the elevated structure can allow for better air circulation, potentially reducing heat buildup and improving the efficiency of the solar panels.

  5. Structural Considerations:

    • The design must account for additional weight and wind load on the building, ensuring that the primary roof can support the secondary structure safely.

  6. Aesthetic and Functional Benefits:

    • This approach can provide aesthetic flexibility and may also include features like overhangs or shading, which can contribute to energy efficiency or protection from the elements.
