All solar farms connect to a specific point on the electrical grid, the vast network of wires that connects every power generation plant to every home and business that consumes power. That point is called the “point of interconnection,” or POI.
The 2020 National Electrical Code (NEC) has introduced pivotal updates with profound implications for the solar installation industry, notably within section 705.11, governing load side and supply (line) side connections.
Line-side connection refers to the direct connection of a solar power system to the utility's power line before the main service panel. This type of connection is suitable for large solar systems that require a dedicated disconnect mechanism or when the MSP has met the 120% rule 2.
The utility will only permit the photovoltaic system to interact with the power grid after issuing a formal approval. The process through which a utility verifies a solar system's compliance with its technical and administrative requirements is commonly referred to as the interconnection process.
The majority of US residential and commercial PV systems are grid-interactive (or grid-tied), which means that they are designed to be able to export excess power to the utility grid. Export occurs when the power generated by the solar system is greater than the power used by the loads on site.
Moreover, the National Electrical Code (NEC) mandates that solar systems' combined load should not exceed 120% of the MSP's capacity 1. When integrating solar energy into a building's electrical infrastructure, there are two types of connections to consider: line-side and load-side connections.
