Material Weight vs. Strength Trade-offs

For mobile and RV applications, weight becomes a critical factor alongside strength:

"When considering the amount of weight being added, aluminum is your friend here. It weighs quite a bit less than galvanized steel per foot and the added strength of steel isn't really needed for your application."

— Reddit user u/zomgimabird, r/SolarDIY (RV roof mounting discussion) ^[5]

This insight helps explain why aluminum dominates the RV and mobile solar market despite steel's superior strength. For Southeast Asian exporters targeting the mobile solar segment, aluminum configurations should be the default recommendation.

Thermal Management: The Overlooked Factor

Multiple discussions highlight thermal performance as an underappreciated consideration:

"You definitely need airflow under those panels or they'll overheat and lose efficiency big time (could be like 20-30% power loss on hot days)."

— Reddit user u/redundant78, r/vandwellers (15 upvotes) ^[5]

This feedback has direct implications for mounting bracket design. Low-profile mounts that minimize air gap may save material costs but reduce energy production—a trade-off that sophisticated buyers understand and factor into procurement decisions.

UV Degradation Awareness

Buyers demonstrate increasing awareness of UV degradation issues:

"Brand new clear 6 mil greenhouse poly has roughly 91% light transmission. That number drops every year until it starts to fall off a cliff in year 4-5."

— Reddit user u/randobot456, r/Greenhouses (discussing UV degradation patterns) ^[5]

While this comment references greenhouse materials, the principle applies directly to plastic junction box components. Buyers expect UV-stabilized materials with documented degradation rates and warranty coverage.
