Projects are refused because they take land out of production \u2014 and yet the same fields are often the flattest, best-drained and best-connected sites available. An <strong>agrivoltaic mounting system<\/strong> resolves that conflict by raising the array high enough, and spacing it widely enough, that crops, livestock or machinery keep working underneath.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/alv-solar.com\/wp-content\/uploads\/2026\/10\/08-agrivoltaic-inline.jpg\" alt=\"Rows of solar modules above grass, showing the inter-row vegetation typical of an agrivoltaic mounting system\" class=\"wp-image-23677\"\/><\/figure>\n\n\n\n<p>The structure is where the whole concept succeeds or fails. A standard ground-mount design dropped onto a farm delivers power but blocks the farm; a properly engineered agrivoltaic mounting system is a different product, with different heights, spans, foundations and coatings.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What makes agrivoltaic mounting different<\/h2>\n\n\n\n<p>Four requirements push the design away from a conventional ground mount:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Light must reach the crop.<\/strong> Module density, row pitch and tilt determine how much photosynthetically active radiation arrives at canopy level.<\/li>\n\n\n<li><strong>Machinery must pass.<\/strong> Tractors, sprayers and harvesters need headroom and turning space, which sets a hard minimum height and span.<\/li>\n\n\n<li><strong>The soil must survive.<\/strong> Foundation design has to limit compaction, preserve topsoil and maintain drainage patterns.<\/li>\n\n\n<li><strong>The environment is aggressive.<\/strong> Ammonia from livestock, dust, irrigation spray and fertiliser all attack coatings faster than open-field conditions do.<\/li>\n<\/ul>\n\n\n\n<p>Each of these translates directly into steel, height and cost. An agrivoltaic structure typically uses 20% to 40% more steel per kilowatt-peak than a low ground mount, which is why the design has to be matched to the farming system from day one.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Design 1: Elevated stilt systems for arable crops<\/h2>\n\n\n\n<p>The classic agrivoltaic layout lifts modules 3 \u2013 4.5 m above ground on tall posts, with spans of 6 \u2013 12 m between post rows so that standard tractors and combines can work beneath.<\/p>\n\n\n\n<p><strong>Best for:<\/strong> wheat, maize, soy, vegetables and any rotation that needs full mechanisation.<\/p>\n\n\n\n<p><strong>Design notes:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Height is set by the tallest machine in the rotation plus clearance \u2014 not by an average.<\/li>\n\n\n<li>Wide spans reduce post count but increase beam depth and foundation loads; the structural optimisation is real work, not a catalogue selection.<\/li>\n\n\n<li>Row pitch is chosen so that the crop still receives 60% \u2013 80% of open-field radiation, depending on the crop&#8217;s shade tolerance.<\/li>\n\n\n<li>Post positions must avoid drainage ditches, field boundaries and future irrigation lines.<\/li>\n<\/ul>\n\n\n\n<p>Those transmission figures come from ongoing field trials; institutes such as <a href=\"https:\/\/www.ise.fraunhofer.de\/en.html\" target=\"_blank\" rel=\"noopener\">Fraunhofer ISE<\/a> publish crop-by-crop results that are far more useful than a single generic number.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Design 2: Vertical and fence-style bifacial arrays<\/h2>\n\n\n\n<p>Vertical arrays stand the modules on edge, facing east and west. They occupy a narrow strip of land \u2014 often a field boundary, fence line or track \u2014 and produce peaks in the morning and evening that complement a conventional array.<\/p>\n\n\n\n<p><strong>Best for:<\/strong> pasture edges, orchard margins, road and rail corridors, and farms that want generation without taking arable land out of rotation.<\/p>\n\n\n\n<p><strong>Design notes:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Land take is very low, often under 5% of the parcel.<\/li>\n\n\n<li>Vertical bifacial modules collect light on both faces, so the rear side must stay clear of fences, hedges and tall grass.<\/li>\n\n\n<li>Wind loading on a vertical plane differs from a tilted array; the foundation and post section must be designed for it specifically.<\/li>\n\n\n<li>Snow accumulation at the base is a real risk in cold climates and needs a clearance detail.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Design 3: Low mounts for sheep grazing<\/h2>\n\n\n\n<p>Sheep grazing under solar is the most mature agrivoltaic model in Europe, North America and Australia. Modules sit at 1.2 \u2013 2.0 m, high enough for animals to graze and for a small utility vehicle to pass, but far lower than arable systems.<\/p>\n\n\n\n<p><strong>Best for:<\/strong> sheep, and in some regions poultry, on pasture that would otherwise need mowing.<\/p>\n\n\n\n<p><strong>Design notes:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The array replaces mowing cost, which is often the hidden business case.<\/li>\n\n\n<li>Cable trays and junction boxes must be out of reach of animals, and connectors must be protected from chewing and rubbing.<\/li>\n\n\n<li>Gates, fencing and water access have to be planned around the array, not retrofitted.<\/li>\n\n\n<li>Ammonia and urine accelerate corrosion at ground level; heavier galvanizing or a ZAM coating is worth the premium.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Design 4: Greenhouse and canopy integration<\/h2>\n\n\n\n<p>Modules can be integrated into greenhouse roofs or shade structures, using semi-transparent modules or spaced layouts that let a controlled share of light through.<\/p>\n\n\n\n<p><strong>Best for:<\/strong> horticulture, nurseries and high-value crops grown under protection.<\/p>\n\n\n\n<p><strong>Design notes:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The mounting system becomes part of the building envelope, so structural codes for buildings apply alongside PV standards.<\/li>\n\n\n<li>Condensation, humidity and cleaning water demand corrosion-resistant hardware and careful detailing.<\/li>\n\n\n<li>Light transmission has to be tuned to the crop, which makes early collaboration with the grower essential.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Design 5: Moveable and seasonal arrays<\/h2>\n\n\n\n<p>Some projects mount modules on skids, rails or tracked frames so the array can be shifted between fields or seasons.<\/p>\n\n\n\n<p><strong>Best for:<\/strong> research sites, temporary land agreements and farms testing agrivoltaics before committing land.<\/p>\n\n\n\n<p><strong>Design notes:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Moveable structures trade structural weight for handling equipment and repeated foundation work.<\/li>\n\n\n<li>Cable management must allow for movement without fatigue failure.<\/li>\n\n\n<li>Economics improve only when the same structure serves several land uses per year.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Height, span and row spacing rules of thumb<\/h2>\n\n\n\n<p>| Farming use | Minimum clearance | Typical span | Row pitch | | &#8212; | &#8212; | &#8212; | &#8212; | | Sheep grazing | 1.2 \u2013 2.0 m | 4 \u2013 6 m | 6 \u2013 8 m | | Arable crops, small tractor | 2.5 \u2013 3.0 m | 6 \u2013 8 m | 9 \u2013 12 m | | Arable crops, combine harvester | 4.0 \u2013 4.5 m | 9 \u2013 12 m | 12 \u2013 18 m | | Orchard \/ vineyard margin | 2.5 m + | 4 \u2013 6 m | Along the row | | Vertical fence array | Ground level | 3 \u2013 5 m | 1 \u2013 2 m strip |<\/p>\n\n\n\n<p>These are starting points, not designs. Local machine dimensions, crop height, snow depth and wind code decide the final figures, and the array layout should be modelled with the actual shade tolerance of the crop.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Soil, drainage and corrosion<\/h2>\n\n\n\n<p>Three details separate a farm-friendly structure from one that damages the land:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Foundations.<\/strong> Driven piles and ground screws disturb far less soil than excavated piers, and they can be removed at end of lease. Restricting vehicle traffic during installation protects the plough layer.<\/li>\n\n\n<li><strong>Drainage.<\/strong> Posts placed in natural flow paths turn a field into a puddle. Survey the site&#8217;s drainage before setting out the grid.<\/li>\n\n\n<li><strong>Corrosion.<\/strong> Livestock housing, slurry storage and irrigation with borehole water all raise the corrosivity category. Specify coating thickness and fastener grade for the actual environment \u2014 the same logic used in our <a href=\"https:\/\/alv-solar.com\/solar-zn-al-mg-steel-ground-mounting-system-the-future-of-durable-solar-support\">Zn-Al-Mg ground mount guide<\/a>.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Choosing an agrivoltaic mounting system supplier<\/h2>\n\n\n\n<p>Ask for four things that a generic ground-mount supplier usually cannot provide:<\/p>\n\n\n\n<p>1. <strong>Structural calculations at your required height and span<\/strong>, not at a standard 1.5 m. 2. <strong>A foundation proposal matched to your soil report<\/strong> and compatible with farm machinery access. 3. <strong>Coating and fastener specification<\/strong> suitable for livestock or irrigation exposure. 4. <strong>A layout drawing that respects field boundaries, drainage and machinery turning circles.<\/strong><\/p>\n\n\n\n<p>Projects that get this right treat the mounting system as part of the farm plan. The economics work because the land keeps producing \u2014 and the array above it is engineered for that job, not adapted to it.

Most agrivoltaic trials target 60% \u2013 80% of open-field light for arable crops, with lower transmission for shade-tolerant varieties.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Is agrivoltaics only for large farms?<\/h3>\n\n\n\n<p>No. Vertical fence arrays, low grazing mounts and greenhouse integration all work at small and medium scale, often on land that would not be used for conventional solar.<\/p>","protected":false},"excerpt":{"rendered":"<p>Farmland is becoming the most contested surface in solar.
