Many systems develop loose panels, rust, or even collapse after 3\u20135 years of operation \u2013 and the root cause is often errors made during installation. This article covers the eight most common installation mistakes and provides the correct solutions.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">1. Common Mistakes and Correct Practices<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Mistake 1: Not Assessing Roof Load\u2011Bearing Capacity<\/h3>\n\n\n\n<p><strong>Signs<\/strong>&nbsp;: Installing according to drawings without calculating actual roof capacity.<\/p>\n\n\n\n<p><strong>Consequences<\/strong>&nbsp;: Structural damage, leaks, and in severe cases, cracked slabs or collapse.<\/p>\n\n\n\n<p><strong>Correct Practice<\/strong>&nbsp;:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Have a structural engineer verify roof load capacity<\/li>\n\n\n\n<li>For older buildings, consider reinforcement before installation<\/li>\n\n\n\n<li>For flat\u2011roof ballasted systems, calculate the load per square meter<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Mistake 2: Insufficient Foundation Strength (Ground\u2011Mount)<\/h3>\n\n\n\n<p><strong>Signs<\/strong>&nbsp;: Low concrete grade, insufficient curing time, insufficient pile depth.<\/p>\n\n\n\n<p><strong>Consequences<\/strong>&nbsp;: Cracking, settlement, tilting \u2013 overall instability of the mounting structure.<\/p>\n\n\n\n<p><strong>Correct Practice<\/strong>&nbsp;:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Concrete grade not lower than C25<\/li>\n\n\n\n<li>Curing time at least 7 days<\/li>\n\n\n\n<li>Pile depth calculated based on soil conditions \u2013 generally not less than 1.5m<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Mistake 3: Incorrect Bolt Torque<\/h3>\n\n\n\n<p><strong>Signs<\/strong>&nbsp;: Bolts either too loose or over\u2011tightened, tightened by feel.<\/p>\n\n\n\n<p><strong>Consequences<\/strong>&nbsp;: Looseness causes movement; over\u2011tightening damages threads or breaks bolts.<\/p>\n\n\n\n<p><strong>Correct Practice<\/strong>&nbsp;:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Use a torque wrench and tighten to design values<\/li>\n\n\n\n<li>Typical torque: M8 bolts 15\u201320 N\u00b7m, M10 bolts 30\u201340 N\u00b7m<\/li>\n\n\n\n<li>Check and mark each bolt after installation<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Mistake 4: Neglecting Corrosion Protection<\/h3>\n\n\n\n<p><strong>Signs<\/strong>&nbsp;: Cut ends of galvanized parts left uncoated; different metals in direct contact.<\/p>\n\n\n\n<p><strong>Consequences<\/strong>&nbsp;: Rust appears at cut ends within 3\u20135 years; galvanic corrosion accelerates damage.<\/p>\n\n\n\n<p><strong>Correct Practice<\/strong>&nbsp;:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Apply zinc\u2011rich paint to all cut edges<\/li>\n\n\n\n<li>Use insulating gaskets between aluminum and steel<\/li>\n\n\n\n<li>Add extra protective coating for coastal projects<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Mistake 5: Poor Waterproofing (Roof Mounts)<\/h3>\n\n\n\n<p><strong>Signs<\/strong>&nbsp;: Simple sealant application at hook points without an additional waterproof layer.<\/p>\n\n\n\n<p><strong>Consequences<\/strong>&nbsp;: Roof leaks that are difficult and expensive to repair.<\/p>\n\n\n\n<p><strong>Correct Practice<\/strong>&nbsp;:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Install an additional waterproof layer under each hook point<\/li>\n\n\n\n<li>Use weather\u2011resistant silicone structural sealant<\/li>\n\n\n\n<li>For tile roofs, use dedicated waterproof gaskets<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Mistake 6: Ignoring Thermal Expansion and Contraction<\/h3>\n\n\n\n<p><strong>Signs<\/strong>&nbsp;: No expansion gaps between rails and connectors.<\/p>\n\n\n\n<p><strong>Consequences<\/strong>&nbsp;: Temperature changes create stress concentration, loosening bolts or deforming connectors.<\/p>\n\n\n\n<p><strong>Correct Practice<\/strong>&nbsp;:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Provide expansion gaps every 6\u20138m on long rails<\/li>\n\n\n\n<li>Use slotted connectors<\/li>\n\n\n\n<li>Avoid completely rigid long\u2011span connections<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Mistake 7: Improper Electrical Grounding<\/h3>\n\n\n\n<p><strong>Signs<\/strong>&nbsp;: Mounting system not grounded or grounding unreliable.<\/p>\n\n\n\n<p><strong>Consequences<\/strong>&nbsp;: Lightning current cannot be dissipated, damaging equipment or even causing fire.<\/p>\n\n\n\n<p><strong>Correct Practice<\/strong>&nbsp;:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Equipotential bonding of the entire metal mounting structure<\/li>\n\n\n\n<li>Ground resistance &lt; 4\u03a9<\/li>\n\n\n\n<li>At least two grounding points per panel string<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Mistake 8: No Maintenance Access<\/h3>\n\n\n\n<p><strong>Signs<\/strong>&nbsp;: Panels packed too tightly without walkways.<\/p>\n\n\n\n<p><strong>Consequences<\/strong>&nbsp;: Cleaning and repairs become very difficult; stepping on panels causes micro\u2011cracks.<\/p>\n\n\n\n<p><strong>Correct Practice<\/strong>&nbsp;:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Leave at least 500mm walkway between panel rows<\/li>\n\n\n\n<li>Reserve safe walkways at roof edges<\/li>\n\n\n\n<li>Provide service roads for large solar farms<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">2.
