A practical buyer explanation of solar balance of system components and how they are sourced for PV projects.

What Is Solar BOS?

Solar BOS means the balance of system components needed to connect, protect, mount and complete a solar installation, excluding the solar panels themselves.

Solar BOS usually includes mounting systems, PV cables, connectors, DC protection, combiner boxes, AC protection, distribution boards, grounding and selected storage accessories.

How buyers should read this

For procurement, BOS should be quoted as a project package because cable size, connector rating, protection devices and box configuration affect each other.
