Photovoltaic Module JSON-LD

Photovoltaic Module JSON-LD Description

This json-ld template is used to store metadata information commonly used to describe photovoltaic (PV) Modules. There is information included on the cells, encapsulant, backsheet, electrical properties, and module dimensions. Note that a lot of the material included in this json pulls from the OrangeButton Taxonomy.
