Introduction<\/h2>\n\n\n\n

Solar mounting accounts for about 5%\u201310% of the total cost of a PV system, but its quality and design directly affect the safety and lifespan of the entire installation. Many projects try to save money on mounts, only to find that later repair costs far exceed the amount saved. This article analyzes the cost structure of solar mounting systems and provides practical purchasing advice.<\/p>\n\n\n\n

1. Detailed Cost Breakdown of Solar Mounts<\/h2>\n\n\n\n

1.1 Mount Cost as a Percentage of Total PV System Cost<\/h3>\n\n\n\n

Note: Ground\u2011mount costs are lower ($0.08\u20130.14\/W), while small roof systems are higher ($0.14\u20130.22\/W).<\/p>\n<\/blockquote>\n\n\n\n

1.2 Mount Cost Sub\u2011Breakdown<\/h3>\n\n\n\n

For a typical 10kW roof system (total mount cost approx $1,000\u20131,600):<\/p>\n\n\n\n

Note: Although aluminum has a higher unit price, its low density means that for the same weight, aluminum covers a larger area.<\/p>\n<\/blockquote>\n\n\n\n

3. Strategies to Save Money on Mount Purchases<\/h2>\n\n\n\n

3.1 Bulk Purchasing to Lower Unit Price<\/h3>\n\n\n\n

Manufacturers typically use tiered pricing:<\/p>\n\n\n\n

Purchase Volume<\/th>Price Reduction<\/th><\/tr><\/thead>
<50kW<\/td>Base price<\/td><\/tr>
50\u2013200kW<\/td>5%\u201310% off<\/td><\/tr>
200kW\u20131MW<\/td>10%\u201315% off<\/td><\/tr>
>1MW<\/td>15%\u201325% off<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

Tip: Combine multiple projects or coordinate with nearby projects for joint purchasing.<\/p>\n\n\n\n

3.2 Optimize Design to Reduce Steel Usage<\/h3>\n\n\n\n
    \n
  • Reasonable span length: typically 1.5\u20132m \u2013 longer spans require heavier profiles<\/li>\n\n\n\n
  • Optimize tilt angle: choose an economical tilt based on local latitude<\/li>\n\n\n\n
  • Use high\u2011strength steel (Q355B instead of Q235B): 10%\u201315% weight reduction for the same strength<\/li>\n<\/ul>\n\n\n\n

    3.3 Choose the Right Corrosion Protection Level<\/h3>\n\n\n\n
    Environment<\/th>Recommended Protection<\/th>Y\u1ebfu t\u1ed1 chi ph\u00ed<\/th><\/tr><\/thead>
    Normal inland<\/td>Hot\u2011dip galvanized 65\u03bcm<\/td>1.0<\/td><\/tr>
    Industrial area<\/td>Hot\u2011dip galvanized 85\u03bcm<\/td>1.1<\/td><\/tr>
    Coastal (1\u20135km from shore)<\/td>Hot\u2011dip galvanized 85\u03bcm + topcoat<\/td>1.3<\/td><\/tr>
    Coastal (<1km from shore)<\/td>Aluminum \/ 316L stainless<\/td>1.5\u20132.0<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

    Do not over\u2011specify in mild environments, but do not cut corners in highly corrosive areas.<\/p>\n\n\n\n

    4. Purchasing Pitfalls to Avoid<\/h2>\n\n\n\n

    4.1 Beware of Low\u2011Price Traps<\/h3>\n\n\n\n

    Common tricks:<\/strong><\/p>\n\n\n\n

      \n
    • Using cold\u2011galvanized instead of hot\u2011dip galvanized (cold galvanizing rusts within 3 years)<\/li>\n\n\n\n
    • Insufficient galvanized coating thickness (<40\u03bcm)<\/li>\n\n\n\n
    • Thinner steel than specified (2.0mm spec but only 1.5mm actual)<\/li>\n\n\n\n
    • Nh\u00f4m t\u00e1i ch\u1ebf t\u1eeb ph\u1ebf li\u1ec7u (\u0111\u1ed9 b\u1ec1n d\u01b0\u1edbi y\u00eau c\u1ea7u)<\/li>\n<\/ul>\n\n\n\n
