Path-Q Solar
Should a solar design prioritize maximum annual production or production during business hours?
Answer
For many businesses, production during operating hours can be more valuable than maximum annual production because it may be used directly on site. The correct priority depends on the value of self-consumption, exported energy, demand charges, seasonal loads, and the cost of changing orientation or system size.
Key points
- Annual production measures energy quantity, not necessarily its financial value.
- Daytime production can reduce purchases during business hours and may better match operating demand.
- A design optimized for annual output may generate more energy outside operating hours.
- Compare time-matched load and generation rather than relying only on annual totals.
What it depends on
- Hourly business load and operating schedule
- Value and treatment of exported energy
- Demand-charge structure where applicable
- Roof orientations, shading, system cost, and seasonal use
Risks and trade-offs
- Prioritizing daytime output may sacrifice some annual energy.
- A production profile that matches current hours may be less suitable if the business schedule changes.
- Financial results require current utility and tariff information.
Information you may need
- Interval consumption data and operating schedule
- Current bill structure and export treatment
- Production profiles for alternative orientations or layouts
Your next step
What to do next
Compare annual-output and business-hour-matched designs using hourly energy flows and current bill assumptions.
