Path-Q Solar

Why might two homes with the same solar system save different amounts?

Answer

Savings differ because homes have different electricity use, timing, rates, export compensation, shading, roof orientation, weather, fixed charges, and future consumption.

Key points

  • Production can differ even with identical equipment.
  • Higher usage does not always mean higher savings if consumption timing is unfavorable.
  • Bill structures can dominate the result.

What it depends on

  • Load profile
  • Site production
  • Utility pricing and export rules

Risks and trade-offs

  • Comparing system size alone is misleading.
  • Weather and household behavior create year-to-year variation.

Information you may need

  • Both homes' bills
  • Production estimates
  • Applicable rate structures

Your next step

What to do next

Compare avoided purchases, exports, fixed charges, and annual production separately for each home.
