It supports the solar panels, resists wind and snow loads, and ensures a service life of over 25 years. Choosing the wrong mounting structure can render even the best solar modules ineffective. This article provides a detailed comparison of roof mounts and ground mounts to help you make the right decision.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">1. Why Is a Solar Mounting System So Important?<\/h2>\n\n\n\n<p>Many people focus their budget on solar panels and inverters while overlooking the mounting system. In reality, the mounting structure is often the most cost-sensitive part of a PV system and the most likely to present safety risks.<\/p>\n\n\n\n<p>A qualified solar mounting system must meet the following requirements:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Sufficient strength<\/strong>\u00a0\u2013 to withstand local maximum wind speeds and snow loads<\/li>\n\n\n\n<li><strong>Corrosion resistance<\/strong>\u00a0\u2013 to ensure 25 years without rust or failure<\/li>\n\n\n\n<li><strong>Easy installation<\/strong>\u00a0\u2013 to reduce labor costs and installation time<\/li>\n\n\n\n<li><strong>Adjustability<\/strong>\u00a0\u2013 to suit different orientations and tilt angles<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">2.
