What is a BOS component?

There is not a lot to mention about a balance of system or BOS component; but, it is still a critical mention to reduce any potential surprises for a new solar installation query. BOS components are necessary to connect your solar energy system to your electrical panel and meter! These are the wires that allow the DC energy to pass through your sister to convert into AC energy.

For your system to function correctly, BOS components must be included in your solar energy system.

What is included in BOS?

  • Wiring

  • Switches

  • Mounting systems

  • Junction boxes

  • Metering system

  • Power conditioners

  • Sensors

Also, all the inverters, battery banks, and equipment that we mentioned before! Other optional components in a solar balance of system include:

  • Maximum power point tracking, MPPT

  • GPS solar trackers

  • Energy management software.

  • Solar concentrators.

  • Solar radiation sensors.

  • Wind equipment.

  • Any additional equipment that may be installed
