Path-Q Solar

What should a small business gather before comparing solar with energy-efficiency upgrades?

Answer

Gather at least a year of interval or monthly energy bills, operating schedules, major equipment loads, building and roof information, planned capital work, and the business's financial and occupancy horizon. Compare solar against efficiency measures using the same assumptions about cost, useful life, disruption, and expected savings.

Key points

  • Identify when and how electricity is used, including seasonal and production-related peaks.
  • List lighting, HVAC, refrigeration, motors, controls, insulation, and other plausible efficiency opportunities.
  • Record roof ownership, condition, shading, electrical capacity, and lease duration.
  • Compare measures by upfront cost, operating savings, maintenance, downtime, useful life, and flexibility.

What it depends on

  • The quality and time resolution of energy-use data
  • The business's operating schedule and future load
  • Building and equipment condition
  • Available capital and expected time at the premises

Risks and trade-offs

  • Solar may be oversized or undervalued if efficiency changes are not modeled first.
  • Efficiency work may reduce the load available for solar but can also reduce system size and operating cost.
  • Short occupancy or uncertain business plans can weaken the case for either investment.

Information you may need

  • Recent bills and, if available, interval data
  • Equipment inventory and operating schedules
  • Roof, electrical, lease, and building-maintenance records
  • Budget, financing constraints, and planned changes to the business

Your next step

What to do next

Create a baseline load profile and have qualified providers model a combined package, efficiency-first option, and solar-only option on comparable assumptions.
