With significant investment being out in the open and often in remote areas, security is an important concern for large-scale solar farms and solar parks. The theft of plant, panels, cabling and even inverters would be disastrous during installation, but potentially easy to suffer with vehicles entering sites whilst work progresses on other areas. Many solar sites suffer theft, since panels are easy to re-fit elsewhere and copper cabling remains attractive to thieves, yet security is often considered a ‘luxury’ (or an unnecessary evil!). However, well-managed uniformed security is effectively cost-neutral, with savings made in the prevention of lost plant, materials and frustrating downtime.
