We undertake weed control for solar power plants.

Are you struggling with weed control at your solar power plant in the Kanto, Koshinetsu, and Tohoku regions? Our experienced specialized team will keep your power plant clean with appropriate measures!

One of the inseparable issues in operating a solar power plant is the problem of weeds. Neglecting weed control not only prevents the solar power plant from maximizing its performance but also increases the risk of unexpected accidents. - Due to the plant being located far away, proper management cannot be conducted. - The response to the increasingly overgrown weeds cannot keep up year after year. - The power plant is buried in weeds, resulting in decreased power generation. - Weeds have grown so much that it is impossible to access the power plant. - Weeds have grown into the power conditioning unit, almost causing a short circuit. ⇧ We are seeing an increasing number of voices from solar power operators expressing such concerns year after year.
