The useful answer
Krannich is a specialist photovoltaic wholesaler rather than a homeowner installation company. Its role is to help qualified installers obtain compatible components and product support. OC Solar retains responsibility for selecting, approving, installing, and documenting the equipment on each customer project.
Multiple established supply relationships reduce dependence on one catalog or warehouse. They do not permit silent equipment swaps: OC Solar still reviews the complete design, communicates material changes, and keeps the final equipment schedule in the project record.

Why it can matter
Krannich describes its business as distribution of the components that make up photovoltaic systems.
Its U.S. operations publish branches and warehouses serving multiple regions, including California.
OC Solar keeps manufacturer, model, serial, warranty, and approved substitution records tied to the customer project.

A distributor supplies installers with modules, inverters, storage, mounting, accessories, logistics, and product support. The installer remains responsible for the customer design and contracted installation.
The OC Solar proposal and project documents identify the applicable equipment and scope. If availability requires a material change, the substitution follows design, compatibility, documentation, and approval controls.
