In Holland the government wants mandatory inspection of electrical installations and solar power installations on livestock farms to prevent barn fires. Smaller farms must let do this every five years, larger farms every three years. From 175 cows onwards a dairy farm is mentioned large. The costs of the inspections depend on the number of square meters of barn and the number of control cabinets and solar power installation present. They vary from 700 euro to 5400 euro per inspection. In addition to the electrical inspections, livestock farms must have an annual fire safety inspection carried out. The costs of this are 2000 euro per inspection. A re-inspection costs average of 2700 euros. Farmers organizations oppose against this high costs for farmers.
