Case Study: Big Sun Energy achieves rapid fault resolution and NT$1M annual travel savings with TeamViewer

TeamViewer saves unnecessary travel costs of Big Sun Energy’s staff

Big Sun Energy, a Hsinchu, Taiwan solar-cell designer and operator of widely distributed, unattended photovoltaic plants, struggled to monitor and rapidly troubleshoot equipment across remote sites in Taiwan and abroad (Japan, Germany, China, the U.S.). The company needed to identify faults immediately and dispatch the right personnel and materials to minimize downtime and costly travel.

By using TeamViewer’s remote-control tools, monitoring-center engineers can diagnose problems, prepare local staff, and often resolve issues without long onsite stays—what once took a week can now be done in a day. The change cut travel costs (saving over one million Taiwan dollars annually and avoiding individual trips costing ~NT$200,000), sped repairs, let 2–3 engineers support 200–300 customers (up from 10–20), and strengthened customer trust and business growth.
