What does it mean to connect a photovoltaic panel to a load

What is a load-side PV connection?

Having said that, battery backup systems, partial load, and whole-house are becoming increasingly common in many of these load-side connections. A load-side PV connection is an electrical connection of the PV system output (power source) to a circuit in the building or dwelling, which is on the load side of the main service disconnect.

How do solar panels connect to the grid?

Connecting solar panels to the grid can be done through a line or supply-side connection. This involves connecting the solar panels directly to the main electrical supply of your home. As a result, the solar panels' electricity can power your home's appliances and other devices.

How do grid-tied PV systems work?

Therefore, we’ll focus here on grid-tied PV systems. Connecting your solar array to the grid means tying the PV conductors to your existing electrical infrastructure. Line-side interconnections consist of connecting the solar on the utility side of your facility’s primary electrical panel or switchboard.

How do you connect a solar inverter to the grid?

The instant it comes out of the main panel and into your building it’s considered load side. So, with that basic information in mind, let’s talk about the two ways you can connect your solar system to the grid. With a load side tap, your solar inverter is wired directly to your electrical panel through a circuit breaker.

What happens if a solar PV system produces more electricity?

If your solar photovoltaic (PV) system produces more electricity than you can use, the excess is sent to the grid where it flows to your neighbor and their neighbor and so on. The process of connecting a solar PV system to the larger electric grid is called interconnection and it’s often the final step in the solar panel installation process.

How do inverters connect to electrical panels?

Circuit breaker connection: The AC wires from the inverter connect to the electrical panel through a circuit breaker. This is the most common type of connection with residential systems and is always allowed by utilities. It is also used with commercial applications whenever the main panel can accommodate the PV backfeed current.
