4 FAQs about [Utility-interactive photovoltaic systems]

What is a utility-interactive photovoltaic system?

According to Section 690.2 of the National Electrical Code (NEC) (NFPA 70-2005), a utility-interactive photovoltaic (PV) system is a 'photovoltaic system that operates in parallel with and may deliver power to an electrical production and distribution network'.

What is a solar photovoltaic system?

A solar photovoltaic system is a renewable energy technology that has the complete setup required to harness solar energy as electricity. These systems can be on-grid systems, where the solar energy is converted into AC power to integrate into the grid, or they can be standalone or off-grid AC or DC power systems.

What are the different types of solar photovoltaic systems?

Let’s take a look at three different types of solar photovoltaic systems. A grid-connected solar photovoltaic (PV) system, otherwise called a utility-interactive PV system, converts solar energy into AC power. The solar irradiation falling on the solar panels generates photovoltaic energy, which is DC in nature.

How are photovoltaic power systems classified?

Photovoltaic power systems are generally classified according to their functional and operational requirements, their component configurations, and how the equipment is connected to other power sources and electrical loads. The two principal classifications are grid-connected or utility-interactive systems and stand-alone systems.
