Since a Solar Powered Farm Electric Fence in Kenya is built to last a very long time, there is a need to have the construction or installation of the electric fence done right from the start. In such a case, there is a need to use high-quality electric fencing materials. A farm electric fence has various specifications that depend on the scope of the fence. For instance, a farm to keep human intrusion away would be different from one whose intention is to keep elephants away.

Briefly, treated wooden posts are used to construct a solar-powered electric fence in Kenya. On the other hand, where treated wooden posts would not be the prefered choice, steel or concrete posts would be used. Steel posts can also be galvanized to extend their lifetime.
Here below are some of the most typical material specifications for a solar-powered electric fence in Kenya.
Treated Wooden Posts as strainers for an electric fence
- Pressure treated in copper chrome arsenate (CCA){tanalith}C to the chemical penetration of at least 1 inch (25mm)
- Size to be at least 5-6 Inches diameter, length 10 feet
- Knot-free and split free
- Bound at top and bottom by a hoop iron 25mm wide and stapled by a 1-inch staple nail.
Treated Wooden Posts as Line posts
- Pressure treated in copper chrome arsenate (CCA){tanalith}C to the chemical penetration of at least 1 inch (25mm)
- Size to be at least 4-5 Inches diameter, length 9 feet.
- Knot free and split-free.
- Bound at top and bottom by a hoop iron 2.5mm wide and stapled by a 1-inch staple nail.
