Solar Panel Installation in Willoughby

Project Overview:

MPV Solar recently completed a residential solar panel installation in Willoughby, located on Sydney’s Lower North Shore. The homeowner wanted a small yet efficient solar system to help reduce electricity bills and take advantage of clean, renewable energy. After exploring several solar providers, they chose MPV Solar, a trusted, family-owned company with over 30 years of experience delivering premium solar system installations across Sydney.

This project demonstrates MPV Solar’s ability to design compact, high-performing solar systems that deliver strong results even on smaller rooftops.

System Specifications:

Panels Installed: 10 × 320 W LG Solar panels
Inverter: 3 kW Fronius Primo inverter

Project Objectives:

Reduce household electricity costs with a small, efficient solar system
Maximise solar generation from limited roof space
Use reliable, premium components with long-term warranties
Deliver a high-quality system installed by MPV’s in-house, CEC-accredited team

Project Summary:

For this Willoughby home, MPV Solar installed a 3.2 kW solar system comprising 10 LG 320 W panels paired with a Fronius Primo 3 kW inverter. This compact system was designed for smaller roof areas, delivering excellent performance and energy savings without compromising on quality.

The system now offsets much of the home’s daytime electricity usage, helping to lower energy bills and reduce carbon emissions. The Fronius inverter allows real-time monitoring, ensuring the system continues to operate at peak performance.

Installed by MPV Solar’s experienced in-house electricians, this project reflects MPV’s commitment to reliable, efficient, and locally supported solar installations — no subcontractors, just quality workmanship and long-term care.
