Path-Q Solar

What should I compare when quotes include different inverter sizes?

Answer

Compare DC-to-AC ratio, modeled clipping, annual output, operating range, backup capability, warranty, replacement cost, and whether the utility permits the proposed AC capacity.

Key points

  • A larger inverter is not automatically better.
  • Different roof orientations may justify different sizing.
  • Check whether battery or future expansion is included.

What it depends on

  • Panel capacity and layout
  • Production model
  • Interconnection and future expansion requirements

Risks and trade-offs

  • A smaller inverter may clip more.
  • A larger unit may cost more or be underused.

Information you may need

  • Detailed equipment list
  • Clipping estimate
  • Warranty and interconnection assumptions

Your next step

What to do next

Put both designs into a side-by-side comparison using the same annual-load and production assumptions.
