panelbank

Panelbank refers to a collection of panels arranged to function as a single electrical or display unit. The term is used most often in two contexts: solar power installations and electrical distribution within buildings or facilities. In both uses, a panelbank implies a deliberate grouping designed to optimize performance, management, or safety.

In solar applications, a panel bank is a group of photovoltaic modules connected together to form a single array. The individual panels may be wired in series to increase voltage or in parallel to increase current. A panel bank typically includes wiring harnesses, a combiner box, protection devices such as fuses or breakers, and is connected to an inverter or charge controller. Performance depends on factors like orientation, shading, temperature, and module mismatch.

In electrical distribution, a panel bank can refer to a bank of circuit breaker panels that feed a portion of a building or data center. This arrangement centralizes power distribution, protection, and monitoring for a defined zone and must comply with applicable electrical codes and safety practices. Proper clearance, cooling, and labeling are important.
