What PV Evolution Labs does

PV Evolution Labs, operating as Kiwa PVEL, is a Napa, California-based solar PV module reliability and performance testing laboratory founded in 2010 and now a subsidiary of Kiwa Group, an international testing, inspection, and certification company. The company operates the Product Qualification Program (PQP), a comprehensive testing protocol covering thermal cycling (600 cycles vs. the IEC standard 200), damp heat, mechanical stress, hail stress, potential induced degradation, UV-induced degradation, light and elevated temperature-induced degradation, backsheet durability, PAN performance, and incidence angle modifier testing. PQP results feed into the annual PV Module Reliability Scorecard, now in its 12th edition (2026), which publicly ranks Top Performer manufacturers and BOM types, functioning as a procurement reference for the downstream solar industry.

Kiwa PVEL serves a two-sided customer base. On the supply side, PV module manufacturers (75+, with 600+ module types tested to date) submit products for PQP testing, factory witness validation, and bankability documentation, seeking third-party reliability validation and Top Performer recognition. On the demand side, the Premium Partner Program provides 400+ downstream solar developers, asset owners, and operators with quarterly BOM-level test data, presentations, and module-selection diligence support, converting laboratory outputs into procurement intelligence. Supporting services include Pre-Shipment Inspection, Batch Testing, Ongoing Reliability Monitoring, and the joint Solar Technology and Cost Service (STAC) offered with Exawatt and CRU. Revenue mechanics blend project-based professional services (PQP testing) with recurring subscription revenue (Premium Partner Program and Scorecard executive summary distribution), supported by direct enterprise sales globally.

Core offering

PV Evolution Labs (Kiwa PVEL) is an independent solar PV module reliability and performance testing laboratory that operates the proprietary Product Qualification Program (PQP), an extended test sequence (TC, DH, MSS, HSS, PID, UVID, LID+LETID, PAN, IAM, BDS) going beyond IEC/UL certification standards. The company's commercial offerings include direct PQP testing services for module manufacturers, a subscription-based Premium Partner Program delivering quarterly BOM-level data to downstream solar developers and asset owners, and the annual PV Module Reliability Scorecard publication, supported by Pre-Shipment Inspection, Batch Testing, and Ongoing Reliability Monitoring services.

Product overview

Kiwa PVEL operates as a specialized solar module reliability and performance testing laboratory, offering a unified product qualification ecosystem. The core Product Qualification Program (PQP) provides comprehensive testing across multiple reliability and performance dimensions, while the annual PV Module Reliability Scorecard publishes independent test results showcasing Top Performer manufacturers. The Premium Partner Program delivers ongoing quarterly BOM-level data to subscribers. The testing portfolio includes reliability tests (Thermal Cycling, Damp Heat, Mechanical Stress Sequence, Hail Stress Sequence, PID, UVID, LID+LETID, Backsheet Durability Sequence) and performance tests (PAN Performance, Incidence Angle Modifier). Supporting services include Pre-Shipment Inspection, Batch Testing, and Ongoing Reliability Monitoring. The Solar Technology and Cost Service (STAC), offered jointly with Exawatt and CRU, provides additional market intelligence.
