Which is better for shading: SolarEdge or Enphase?

Enphase is the gold standard for reliability and shading. If one panel goes down, the rest keep working. SolarEdge is better if you have a simple roof, want maximum raw efficiency, or are on a slightly tighter budget for a large installation.

Frequently Asked Questions

Is Enphase really worth the extra cost?

For complex roofs with shading from trees or chimneys, yes. The independent operation of microinverters prevents shaded panels from dragging down the whole system.
