Path-Q Solar
How does a business with a large refrigeration load differ from an office when evaluating solar?
Answer
A refrigeration-heavy business usually has a more continuous load than a typical office and therefore often has some daytime overlap with solar, while office demand is commonly more concentrated in daylight working hours. Refrigeration also has important peak, startup, temperature-control, and reliability requirements that should be analyzed separately from annual energy consumption.
Key points
- Refrigeration may run for long periods, including nights and weekends, while office loads may be concentrated in working hours.
- Door openings, ambient conditions, defrost cycles, compressor staging, and equipment condition affect consumption.
- Solar can offset energy but does not by itself ensure refrigeration continuity during outages.
- Demand charges and peak equipment operation may materially affect the commercial value.
What it depends on
- Refrigeration equipment type and duty cycle
- Ambient temperature and operating conditions
- Business hours and product-storage requirements
- Demand charges, backup requirements, and export treatment
Risks and trade-offs
- Using office-like assumptions can understate a continuous refrigeration load.
- Using annual refrigeration energy alone can miss peak demand and outage risks.
- Storage or backup designed for refrigeration adds cost and requires appropriate capacity and controls.
Information you may need
- Interval demand and energy data
- Refrigeration equipment inventory and schedules
- Defrost and startup behavior
- Required continuity during grid outages
Your next step
What to do next
Compare interval load profiles and peak demand for the refrigeration business and office baseline, then evaluate solar and backup separately.
