Certification Process

Other Testing Processes

Initial Screening Method (ISM)

Optional and abbreviated test method that can offer key feedback to product designers, manufacturers, and brand owners and indicate whether the product is likely to meet the Quality Standards.

Accelerated Verification Method (AVM)

Optional and faster alternative to Quality Test Method (QTM) testing. Companies must meet certain eligibility criteria.

Renewal Testing

Used to maintain a product’s certification status. To be performed within two years after meeting the Quality Standards. Learn more about the process or read the full Policy for Renewing Test Results.

Market Check Method (MCM)

Performed on certified products at VeraSol’s discretion. Samples are collected from the marketplace. This process ensures that the quality of products sold in the market matches what was measured at initial quality certification testing. Initial MCM testing is paid for by VeraSol. If product fails initial MCM, companies can submit the product for retesting at their own expense within a reasonable time frame. See Market Check Testing Policy. 

Pay-as-you-go Energy Systems (PAYG)

PAYG-enabled systems should meet the same requirements as standard systems. To understand how certain requirements in the Quality Standards apply to PAYG systems, please read our policy on Quality Assurance for Pay-as-you-go (PAYG) Energy Systems. See PAYG Policy. 

Pay-as-you-go Market Check Test (PAYG – MCT) Method

The PAYG – MCT method is used to confirm basic PAYG functionality of solar energy kits sold in the market if concerns arise regarding the function of a product’s PAYG system. The procedure tests features specific to the PAYG system that are only functional in the intended location of use, and could not be tested during a typical Market Check Test. See PAYG Market Check Test Policy.
