Penetrating vs Non-Penetrating Roof Mounts: Selection Criteria and Limits
As the utilisation of solar energy is consistently growing higher, consumers like homeowners and businesses are increasingly exploring rooftop-mounted solar panels as a more cost effective and sustainable solution. Sometimes choosing the right solar panel seems to be a critical decision.
Let’s look forward to this blog to understand the basic features of different types of solar panels present for your use. Broadly, there are two types of roof-mounted solar structures: penetrating and non-penetrating roof mounts. Both have specific benefits as well as limitations. This blog would help out to choose the best and make an informed choice.
What is Penetrating Roof Mount?
Penetrating roof mount involves drilling holes into the roof to secure the solar roof mounting structure directly to the building. Generally, it is used on a sloping rooftop. These are mainly used for the following reasons.
Key Features:
- Provide a strong and durable anchor for roof-mounted solar panels
- Penetrating roof mount is ideal for high wind or snow-prone locations where extra stability is needed.
- Dominating over the traditional solar panel mounting systems
Advantages:
- Upgrades the structural stability
- Minimum risk of panel displacement
- Suitable for both domestic and commercial applications
Limitation:
- If not properly sealed, roof penetration can be compromised
- A skilled professional is required for perfect installation
- Unsuitable for dilapidated structures, homes, or a delicate rooftop
What are Non-Penetrating Roof Mounts?
Non-penetrating roof mounts are designed to avoid drilling into the roof surface; instead, they rely on ballast systems or other clamping techniques to secure the roof-mounted solar structure. These are typically used on flat rooftops with waterproofing concerns.
Key Features:
- Lightweight, easy to install
- No drilling is used, hence no risk of damaging the roof surface
- Best suited for a flat or low-slope roofing system
Advantages:
- Maintain roof integrity with zero penetration
- Faster installation compared to a penetrating system
- Flexible repositioning of panels if required
Limitation:
- Less stable with high wind speed or without the support of ballast
- Need to be careful with load distribution to avoid any damage
- May not be compatible with solar roof mounting structure
Selection Criteria: Choosing the Right Roof-Mounted Solar Structure
Choosing between the penetrating and non-penetrating roof mount, these factors should be considered:
- Roof Type
a. Slope roofs are best suited for a penetrated mount structure
b. Flat roofs often use a non-penetrating mount to avoid drilling the rooftop
- Load-Bearing Capacity
a. Penetrating structure adds support by anchoring the roof surface
b. Non-penetrating system only adds extra weights to the roof due to ballast or stands
- Climate Condition
a. Pentration is demanded in the high wind or heavy snow region to get maximum stability.
b. In the modern climate, non-penetrating roof mounts offer safe and efficient performance.
- Installation Cost and Time
a. Non-penetrating system is easy to install in less time
b. Penetrated system involves an amount of time and cost in installation
- Maintenance and Longevity
a. Penetrating mounts require precise sealing and ongoing maintenance to preserve the roof.
b. Non-penetrating system demands regular checks for ballast shifting and imbalance of weight distribution.
Final Takeaway
These two types of solar mount structures, penetrating and non-penetrating roof mounts, serve vital roles depending on roof type, load capacity, and local climate. Penetrating mounts bring exceptional stability, especially in high wind or snow conditions. While non-penetrating mounts protect roof integrity and allow fast and flexible installation.
