Path-Q Solar

What are the drawbacks of installing more solar capacity than I currently need?

Answer

Oversizing can increase upfront cost, produce low-value exports, exceed roof or interconnection limits, and leave equipment underused if future consumption does not rise.

Key points

  • Future loads can justify some additional capacity.
  • Export compensation may be lower than the value of avoided purchases.
  • More panels do not eliminate seasonal production mismatch.

What it depends on

  • Future load certainty
  • Export rules
  • System cost and financing

Risks and trade-offs

  • Lower returns
  • More equipment and maintenance exposure
  • Potential design or approval constraints

Information you may need

  • Current and projected loads
  • Export compensation
  • Marginal cost of added capacity
