Path-Q Solar
What additional cost should a small business budget for if solar production testing must be performed outside normal operating hours?
Answer
Budget the provider's incremental after-hours labor, travel, access, supervision, testing equipment, security, and possible remobilization costs; the amount cannot be estimated reliably without a written quote. Also account for any business costs caused by the timing, such as overtime, access coordination, or temporary shutdowns.
Key points
- Ask whether after-hours work is billed at overtime, a fixed call-out rate, minimum hours, or a separate testing fee.
- Include travel, security escort, lift or access equipment, monitoring support, and repeat visits if conditions are unsuitable.
- Confirm whether testing requires operating loads, an outage, export changes, or coordination with the utility.
- Define the test scope, acceptance criteria, report, and responsibility if the system fails.
What it depends on
- Testing method, duration, staffing, and equipment
- Provider rate schedule and after-hours policy
- Site access, security, and tenant operating requirements
- Required utility or operational coordination
- Need for outages, load changes, or repeat testing
Risks and trade-offs
- A lower-cost test may be incomplete if the system cannot be observed under representative conditions.
- After-hours work may reduce operational disruption but increase labor and access charges.
- A failed or inconclusive test can create additional mobilization and delay costs.
Information you may need
- Written testing scope and acceptance criteria
- Provider's itemized after-hours rates and minimum charges
