Last May, I purchased eight\u00a0<a href=\"https:\/\/amzn.to\/2RBqvOQ\" target=\"_blank\" rel=\"noopener sponsored noreferrer\">Renogy 270-watt solar panels<\/a>\u00a0similar to those in the <a href=\"https:\/\/jimkerkhoff.com\/test-roycreekranch\/2017\/11\/14\/more-panels\/\" target=\"_blank\" rel=\"noopener noreferrer\">Solar Rainwater Project<\/a>. At 65 by 39-inches, and weighing 65 lbs., they require a substantial mounting system. In the <a href=\"https:\/\/jimkerkhoff.com\/test-roycreekranch\/2017\/03\/23\/solar-power-rainwater-project-panels-and-angles\/\">Solar Rainwater System<\/a>, I had the advantage of an existing building with a south-facing roof that could hold four panels. It was easy to mount the other two to the front of the building, so very little effort was needed.<\/p>\n<p>The shop&#8217;s roof, on the other hand, is completely shaded. Mounting the panels near the ground was appealing for it&#8217;s simplicity and ready access. Amazon lists several mounting systems, but none of them suited my situation. Most wouldn&#8217;t work well with large panels, and cost was also a factor. I began thinking about a wooden structure that could mount all eight panels.<\/p>\n<p>There were several design considerations:<\/p>\n<ul>\n<li>A south-facing, sunny location<\/li>\n<li>short distance from the shop to reduce copper wire cost and limit energy loss<\/li>\n<li>Resistance to occasional high winds<\/li>\n<li>ease of service<\/li>\n<li>Expandability<\/li>\n<\/ul>\n<h2>Locating the Solar Panel Array<\/h2>\n<p>Roy Creek Ranch is heavily wooded with Live Oak and Ash Juniper, so finding a location that is sunny year round is a challenge. Initial sketches needed an area about 11 feet square with as few trees as possible to the south. They would shade the array &#8212; especially in the winter when the sun is low in the sky. Scouting the area around the shop, I noticed a clearing. There were a few Junipers shading the clearing, but they could be easily removed.<\/p>\n<div class=\"tiled-gallery type-rectangular tiled-gallery-unresized\" data-original-width=\"1300\" data-carousel-extra='{&quot;blog_id&quot;:1,&quot;permalink&quot;:&quot;https:\\\/\\\/jimkerkhoff.com\\\/test-roycreekranch\\\/2019\\\/12\\\/10\\\/how-to-mount-solar-panel-array\\\/&quot;,&quot;likes_blog_id&quot;:62631746}' itemscope itemtype=\"http:\/\/schema.org\/ImageGallery\" > <div class=\"gallery-row\" style=\"width: 1300px;

Four vertical posts would be arranged in an 11-foot square. Two 10-foot posts on the north edge and two 2-foot posts on the south edge would be joined by a platform angled at 34 degrees. The panels would be arranged horizontally on the platform in two columns of four rows. About an hour later, flourescent <a href=\"https:\/\/amzn.to\/355kspr\" target=\"_blank\" rel=\"noopener sponsored noreferrer\">Mason line<\/a> marked the location of each of the four holes for 8-inch concrete piers.<\/p>\n<h2><\/h2>\n<h2>Every project starts with a hole . . .<\/h2>\n<p>Bright and early the next morning, I started digging. My plan was to use leftover sections of 8-inch <a href=\"https:\/\/amzn.to\/38pYiAf\" target=\"_blank\" rel=\"noopener sponsored noreferrer\">Quikrete concrete forming tube<\/a> to form piers that were about 18 inches long with about 1 foot underground. A couple of short rebar sections would be buried in the concrete with a 6-inch <a href=\"https:\/\/amzn.to\/2E4eLw6\" target=\"_blank\" rel=\"noopener sponsored noreferrer\">anchor bolt<\/a> sticking out of the top to attach a steel 4-by-4 post mount.<\/p>\n<p>The ground here is caliche &#8212; a white limestone soil that hardens into rock when dry and compressed. It is difficult to dig. There is 2 to 4 inches of organic soil on top &#8212; easily removed with a spade. I&#8217;ve dug many holes in the caliche over the years, using everything from a post hole digger to a steel rock bar. A little power helps and an 18-volt hammer drill with a 12 by 3\/4-inch rock drill is by far the best. I was able to dig each hole in about 15 minutes with relative ease.<\/p>\n<div style=\"width: 1280px;\" class=\"wp-video\"><video class=\"wp-video-shortcode\" id=\"video-1173-1\" width=\"1280\" height=\"720\" poster=\"https:\/\/jimkerkhoff.com\/test-roycreekranch\/wp-content\/uploads\/2019\/12\/18-volt-hammer-drill-and-bit.jpg\" preload=\"metadata\" controls=\"controls\"><source type=\"video\/mp4\" src=\"https:\/\/jimkerkhoff.com\/test-roycreekranch\/wp-content\/uploads\/2019\/12\/Digging-Caliche-with-a-Hammer-Drill.m4v?_=1\" \/><a href=\"https:\/\/jimkerkhoff.com\/test-roycreekranch\/wp-content\/uploads\/2019\/12\/Digging-Caliche-with-a-Hammer-Drill.m4v\">https:\/\/jimkerkhoff.com\/test-roycreekranch\/wp-content\/uploads\/2019\/12\/Digging-Caliche-with-a-Hammer-Drill.m4v<\/a><\/video><\/div>\n<h2><\/h2>\n<h2>The Concrete Pour<\/h2>\n<p>With holes dug, we were ready for concrete.
