This document describes the Quality Standards for Solar Home System Kits, which set a baseline level of quality, durability, and truth in advertising to protect consumers. Kits covered by these Standards must have a peak power of 350 W or less and a DC voltage of 35 V or less. [Note, products 10 W and smaller are evaluated as pico-products under the Pico-PV Quality Standards. If products between 11-15 W need to be evaluated as pico-PV products to meet an outside requirement, an additional two samples may be evaluated during testing and the product will be required to meet both sets of quality standards.]

Conformance with the Quality Standards is evaluated based on results from laboratory testing according to the Quality Test Method (QTM) as defined by IEC/TS 62257-9-5. Products that have met the Quality Standards are issued a Spec Sheet and Verification Letter and posted on a digital product database.

Please follow this Change Log to see what changed when in each set of quality standards.
