technical articleAging Battery SOC Limits: Verify the Available-Capacity…
In SAM, minimum and maximum dispatch SOC limits use current available battery capacity, which changes with degradation and replacement. Buyers should request nominal and available capacity, SOC limits, and boundary calculations together. Confirm the actual controller’s definitions separately: SAM’s modeling convention does not verify equipment behavior.

technical articleStreetlight Acceptance: Undervoltage vs 0–10V Tests
Request separate supply-voltage and 0–10V interface tests, then investigate combined conditions. Define equipment, measurements and acceptance criteria beforehand. The DOE research summaries support investigating both paths but provide no universal fault thresholds or product-specific acceptance results.

technical articlePV Curtailment Compensation: Rate and SAM Model Disclosure
Disclose the exact modeled curtailment compensation rate, its units and evidence, and the selected financial model. SAM explicitly documents this compensation treatment for Single Owner and Merchant Plant models; the cited sources establish no numerical rate or project payment entitlement.

technical articleStreetlight Energy Measurement: Evidence for Billing…
Buyers should request applicable clauses, configuration-specific test evidence, calibration documentation, and written billing acceptance. The cited DOE sources identify relevant ANSI standards and measurement research but provide no numerical accuracy limits, detailed test procedures, or billing approval criteria.

Recommended bidder evidence includes configuration-specific test reports, operating records, transparent modeling assumptions and a documented delivery scope. The cited sources do not verify any particular battery offer’s commercial readiness.

technical articleWhat installation and operating cost items should a PV bid…
SAM assumes a mechanism exists to enforce modeled export limits and says its costs should be included in installation and/or operating costs. Request an itemized, conditional bid covering engineering, proposed equipment, integration, commissioning, and recurring support. Project-specific hardware, prices, response performance, and approval requirements remain unknown.
