Solar Farm Fencing

Solar farms are one of the fastest-growing sources of renewable energy in the UK. But, as more solar farms are installed, protecting the perimeter of these sites has never been more important. A compromised fence can put investments at risk, from theft of panels and cabling, vandalism, insurance non-compliance and even wildlife intrusion.

Postsaver +PLUS can help safeguard solar farm perimeters by protecting timber posts from rot and decay, backed by a 40-year post-replacement guarantee.

Why Solar Perimeter Fencing is Critical

A solar farm's perimeter fence is its first line of defence. Weak or degraded fencing can lead to: 
Solar panel
  • Theft and vandalism Solar farm are increasingly targeted by thieves
  • Insurance risks Secure perimeter fencing  is required for coverage
  • Site safety concerns Failed posts pose hazards for wildlife, and the public
  • Maintenance costs Replacing broken fences is expensive and disruptive

With the UK’s solar capacity expanding rapidly, site operators and contractors are under increasing pressure to ensure fencing is durable, reliable, and low-maintenance. Protecting the posts that hold your perimeter fencing is a key part of maintaining site integrity and long-term cost-efficiency.

Why Timber Posts are the Smart Choice for Solar Farm Fencing

While steel or concrete posts are sometimes used, timber posts remain a popular choice for solar farm fencing because they offer: 
  • Lower upfront cost compared to other post materials
  • Ease of installation across rural settings, lightweight to handle
  • Flexible for a range of fences including mesh, stock and wildlife
  • Sustainable optimises timber carbon storage benefits
However, timber posts are vulnerable to rot and decay at ground level, especially in the damp UK climate. Without protection, the lifespan of timber posts can be drastically reduced, undermining security and increasing maintenance costs.
