5 Reasons to Choose Treated Round Fence Posts and Fixed Knot Woven Wire for Solar Farm Projects

As the demand of solar farm projects continues to increase among rural settings, selecting the right fencing materials is important for perimeter security, longevity, and eco-conscious durability. There are many fencing products that can be used for solar field fencing; however, we’ll explore why agricultural fencing – specifically treated round fence posts and high-tensile fixed knot wire – leads the way as the superior choice for solar farms. Here’s 5 reasons why:

1. Affordability

When working on the development of a solar field project, budget is a crucial factor, and agricultural fencing provides a high value, more affordable solution compared to other fencing materials, without compromising on strength and stability. A combination of treated wood posts and high-tensile wire offers a more cost-effective solution compared to chain link or steel fencing, offering long-term security at a fraction of the cost. Solar farms cover large acreage, sometimes making chain link or steel fencing materials too costly on a per-foot basis.

2. Eco-Friendly Materials

Agricultural fencing generally provides a lower carbon footprint compared to other fencing materials.

• Eco-friendly Solution: Responsibly sourced wood supports sustainable forestry
• Lower-impact Option: A treated post generally uses less energy to produce, and fixed knot wire requires significantly less metal than chain-link fencing, decreasing the carbon footprint associated with extraction and refinement.

3. Aesthetic Compatibility While Minimizing Environmental Disruptions

Reliability while maintaining environmental balance is a core value to the solar industry. Wooden round posts and woven wire blends seamlessly within the natural rural landscape reducing the visual impact of the project.

• Wildlife-Friendly – Provides a barrier without excessively disrupting local ecosystems, allowing wildlife-friendly spacing for small animals and controlling rodent population, which can aid in reducing potential damage to the solar equipment.

5. Easy Installation with Minimal to No Repeated Maintenance

This style of fencing provides a flexible, versatile and customizable solution for solar projects located in various terrain settings, all while generally requiring minimal to no upkeep.  

• Quick & simple installation – Allows for simple post systems and reduces labor cost 
• Flexible design – Agricultural style fencing is versatile, allowing for wider post spacing, and customization based on project specifications. 

5. Provides a Strong, Reliable Perimeter Barrier

Agricultural style fencing creates a durable perimeter, protecting solar equipment from any potential damage from human or medium to large animal interference. Combined, these materials can withhold harsh conditions and high-stress pressure. Many rural solar farms use 12 foot wooden posts to create an 8-foot-tall perimeter fence, designed specifically for all types of exclusion.  When properly installed, this fencing system is built to last 25+ years—thanks to the durability of pressure-treated posts and strong fixed knot wire.

The Bottom Line

These products offer a sustainable, long-lasting, and cost-effective solution for solar farm perimeter security—delivering reliable protection while blending naturally into the rural landscape. Treated posts paired with fixed knot woven wire creates a fencing system that’s not only durable with low to no maintenance, but also environmentally friendly and visually unobtrusive. For solar developers and contractors, seeking reliability without compromising on aesthetics or budget, this combination remains one of the most trusted fencing solutions on the market.
