Functionality Of Power Optimizers

Power optimizers attach to each solar panel in a system. They track the maximum power point (MPPT) of each panel. This helps in optimizing the energy output of each panel individually.

Unlike traditional string inverters, power optimizers ensure that each panel performs at its best. This is especially useful in situations where some panels may be shaded or dirty. The optimizers send the improved energy output to the central inverter.

The central inverter then converts the optimized DC power to AC power. This power is then used in your home or sent to the grid.

Benefits And Drawbacks

Power optimizers offer several advantages. Here are the main benefits:

  • Increased Energy Output: Each panel performs at its peak, increasing overall efficiency.
  • Shade Tolerance: Panels affected by shade or dirt won’t drag down the performance of the entire string.
