A Solar Distribution Board (DB Board) is a crucial component in a solar power system. It acts as an electrical distribution point, managing the flow of electricity from the solar panels, through the various components, and ultimately to the load or appliances. The DB Board typically includes circuit breakers, fuses, and other protective devices to ensure the safety of the system.

Its primary functions include:

1. *Distribution:* It routes power to different areas or loads within a building.

2. *Protection:* The DB Board incorporates circuit breakers or fuses to protect the system from overcurrent, short circuits, and other electrical faults.

3. *Isolation:* It provides a means to isolate specific sections of the solar power system for maintenance or in case of emergencies.

When installing a solar power system, the DB Board is strategically placed to organize and control the electrical connections, enhancing safety and efficiency in the distribution of solar-generated electricity.
