On‑Grid Solar Systems FAQ

Q1: What is on‑grid solar system?

A: On‑grid (grid‑tied) solar system is a photovoltaic power generation system connected to public utility grid. Solar panels generate DC power, inverter converts DC into AC power matching grid voltage and frequency. Generated electricity can be consumed on‑site; excess power feeds back to the public grid. It is widely used for residential, commercial‑industrial rooftop and ground‑mount solar projects.

Q2: What are the main system components?

A: Solar PV modules, on‑grid solar inverter, mounting brackets, DC combiner box, AC distribution cabinet, DC‑AC cables, surge protection devices, metering meter. No battery energy‑storage unit is required for standard on‑grid configuration.

Q3: How does on‑grid solar work?

A: Solar panels produce DC power under sunlight. On‑grid inverter converts DC into grid‑compliant AC power. Local loads consume generated power first. Surplus electricity flows into utility grid. When solar output is insufficient, power is drawn from the grid to supply loads.

Q4: Will on‑grid solar work during grid power outage?

A: Standard on‑grid inverter features anti‑islanding protection. It will automatically shut down when grid fails for safety reason, cannot supply power to loads during blackout. If backup power during outage is needed, hybrid inverter plus battery storage shall be adopted.

Q5: What are common system capacity ranges?

A: Residential: 3 kW‑20 kW. Commercial rooftop: 30 kW‑1 MW. Utility ground‑mount: 1 MW and above. System size is designed based on available installation area, local solar irradiance and load consumption.

Q6: Inverter types for on‑grid system

A: String inverter for small‑medium projects; central inverter for large ground‑mount solar farms. MPPT function optimizes power output under uneven shading conditions.

Q7: Environmental & installation requirements

A: PV modules shall be installed with proper tilt angle and orientation, avoid long‑time heavy shading. Rooftop installation needs building load‑bearing verification. Ground‑mount system needs qualified foundation. All wiring must comply with local electrical codes.
