Are PV systems compatible with the utility grid?

Interest in PV systems is increasing and the installation of large PV systems or large groups of PV systems that are interactive with the utility grid is accelerating, so the compatibility of higher levels of distributed generation needs to be ensured and the grid infrastructure protected.

Can a photovoltaic system be connected to a building electrical installation?

Indeed, a photovoltaic system can be connected to the building electrical installation at different places: to the main low-voltage (LV) switchboard, to a secondary LV switchboard, or upstream from the main LV switchboard. These options, their advantages and drawbacks are discussed in this blog post. 1.

How do PV systems affect the utility grid?

The variability and nondispatchability of today’s PV systems affect the stability of the utility grid and the economics of the PV and energy distribution systems. Integration issues need to be addressed from the distributed PV system side and from the utility side.

How does a utility verify a photovoltaic system?

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.

Can a solar PV system be connected without a main breaker?

Yes, a solar PV system can be connected using supply side connections even if the panel lacks a main breaker. This involves installing a dedicated disconnect on the supply side of the service equipment, ensuring safe and direct integration with the utility’s supply without overloading the internal panel infrastructure.

Do I need a load-side or supply-side connection to my PV system?

For larger PV systems, a supply-side (of the service disconnect) connection to the premises wiring system may be necessary instead of a load-side connection.
