How Do Different Inverter Types Affect Solar Tracker Performance?

Inverter Selection for Solar Trackers

When choosing an inverter for a solar tracker, it’s essential to consider the type of inverter that best suits the application. For example, a string inverter is suitable for small to medium-sized solar arrays, while a central inverter is more efficient for larger arrays. A hybrid inverter, which combines the benefits of string and central inverters, is ideal for solar trackers with varying panel orientations.

Inverter Type and Solar Tracker Performance

The performance of a solar tracker depends heavily on the inverter’s ability to handle the varying DC power output. A string inverter can handle a maximum power point tracking (MPPT) of 30-40%, while a central inverter can achieve an MPPT of up to 98%. This means that a central inverter can extract more energy from the solar panels, resulting in a higher energy yield. Additionally, a central inverter’s ability to synchronize with the grid allows for a more stable and efficient power output.

Inverter Selection Criteria

When selecting an inverter for a solar tracker, consider the following criteria: maximum power point tracking (MPPT) efficiency, grid synchronization capabilities, and power quality. Look for an inverter with a high MPPT efficiency (above 95%), a fast grid synchronization time (less than 20 milliseconds), and a high power quality factor (above 0.99). By considering these factors, you can choose an inverter that optimizes solar tracker performance and maximizes energy yield.
