Weed Control Sheet

Weed or vegetation management is particularly important for ground-mounted solar systems. Tall weeds growing around the installation can create shading, which can negatively impact system production. It can also cause hot spot heating — if a part of the solar cell is shaded, the cell can heat up to such extreme temperatures that a module can burn out causing permanent damage. Weed-control fabrics or sheets provide a non-chemical way to kill weeds by covering the unwanted vegetation and blocking out the light. While commonly used for landscape applications, these products are finding their way into the solar market. The initial investment for using these sheets is high compared to other methods, but ongoing expenses are said to be minimal. The sheets must be placed properly and covered to prevent the wind from picking them up. The life of the sheets is approximately 10 years.
