Path-Q Solar

How can a small business decide whether to pursue solar after reviewing its bills?

Answer

The business should first analyze when and how much electricity it uses, then test whether a site-specific solar design can reduce purchased energy without conflicting with roof, lease, operational, or capital constraints. Pursue detailed quotes if the business expects to occupy the site long enough and the cash-flow case remains acceptable under conservative assumptions.

Key points

  • Use a full year of bills and, where available, interval data to identify demand patterns, operating hours, seasonal loads, and demand charges.
  • Evaluate roof or ground space, structural condition, shading, electrical interconnection, maintenance access, and future expansion.
  • Compare cash purchase, financing, lease or service arrangements, and the value of batteries or load management.

What it depends on

  • Load profile and utility billing structure
  • Building ownership, lease term, roof condition, and operating horizon
  • System cost, financing, incentives, export treatment, and interconnection requirements

Risks and trade-offs

  • A business may move, expand, or change operations before the investment is recovered.
  • Demand charges and export rules can make bill savings differ substantially from energy production.
  • Roof replacement, downtime, maintenance, insurance, and tax treatment can materially change the case.

Information you may need

  • At least one year of bills and interval load data if available
  • Lease, ownership, roof, insurance, and planned expansion information
  • Capital budget, financing preferences, and required return or payback
  • Site-specific designs and verified utility and incentive terms

Your next step

What to do next

Have several commercial installers model the business's interval load and provide itemized proposals with conservative cash-flow scenarios.
