- Depending on the site and precise characteristics of the solar irradiation, trackers may increase the annual energy yield by up to 27% for single-axis and 37% for dual-axis trackers.
- Almost all tracking system plants use crystalline silicon modules. This is because their higher efficiency reduces additional capital and operating costs required for the tracking system (per kWp installed).
- High wind capability and storm mode: dual-axis tracking systems especially need to go into a storm mode when the wind speed is over 16-20 m/s. This could reduce the energy yield and revenues at high wind speed sites.
- Direct/diffuse irradiation ratio: tracking systems will give greater benefits in locations that have a higher direct irradiation component.
