Path-Q Solar

Should I get solar quotes now or wait until my electricity use changes?

Answer

Get preliminary quotes now if the change is uncertain or distant, but ask installers to model both current and expected usage. Waiting is more useful when a major change is imminent and would materially alter system size, such as electrification, an EV, or a move.

Key points

  • A current quote can reveal roof, electrical, and design constraints before you commit.
  • Future loads should be shown as a separate scenario rather than assumed without evidence.
  • If the change is within roughly the design and installation period, waiting or requesting a re-design may avoid an undersized system.

What it depends on

  • Timing and certainty of the expected usage change
  • Its estimated annual and seasonal electricity demand
  • Whether the proposed system can be expanded later
  • Roof, electrical, financing, and utility-interconnection timing

Risks and trade-offs

  • Sizing only for current use may leave less room for future electrification.
  • Sizing for uncertain future use can increase cost without proportional benefit.
  • A delayed project may face different equipment, pricing, or program conditions.

Information you may need

  • Recent utility usage history
  • Expected timing and type of new loads
  • Whether major roof or electrical work is also planned
  • Quote assumptions for future consumption and expansion

Your next step

What to do next

Ask two or more installers for comparable proposals using current usage and a documented future-load scenario, then compare the design and assumptions.
