What is PV System?
A complete solar setup including panels, inverter, wiring, mounting, and optional battery storage.
Quick Answer
A standard Irish residential PV system is 3–6kWp, grid-tied, and installed on the roof. It typically includes 8–16 panels, a hybrid or string inverter, roof-mounted racking, and a generation monitoring app. Many Irish homeowners add battery storage (5–10kWh) to maximise self-consumption and reduce evening grid imports.

PV System Explained
A PV (photovoltaic) system is the complete set of components needed to generate electricity from sunlight. A typical residential PV system includes solar panels, an inverter (string, hybrid, or microinverters), a mounting system, DC and AC cabling, an isolator switch, and connection to the consumer unit (fuse board). Optional components include battery storage, an export meter, and a monitoring system. The system may be grid-tied (connected to the electricity grid) or off-grid (standalone with battery storage).
