Considered solar installations in Wollongong.

A thoughtful approach for the Illawarra

Wollongong is one of our main service areas. We work with homeowners and businesses to consider rooftop solar, battery storage and EV charging, with design decisions shaped by each individual property rather than a standard package. Our team travels from our Kingsgrove base, and we plan site visits and installations so you know who is coming and what will happen on the day.

Coastal conditions and salt air

Many Wollongong properties sit close to the ocean, where salt air can be harder on outdoor equipment. Panel, inverter and battery manufacturers set their own requirements for coastal installations, so we check those requirements, consider equipment placement and use mounting components suited to the location. Where a site is particularly exposed, we explain what that means for equipment choice and ongoing care. We also talk through practical maintenance, such as keeping an eye on panels and outdoor equipment for salt build-up, and how monitoring can help you notice changes in performance over time.

Escarpment, slopes and shading

The escarpment and hilly terrain shape many Illawarra properties. Depending on where you are, the escarpment, nearby trees or neighbouring homes can shade a roof at certain times of day, and sloping blocks can affect access. Housing ranges from older brick and tile homes to newer builds with metal roofs, so we assess orientation, shading and roof type before proposing a layout.

• Solar-only and solar + battery options
• Battery compatibility assessments
• Home and commercial EV charging
• Existing system repairs and replacements

Services for Wollongong homes and businesses

We design and install rooftop solar for homes and businesses, solar + battery systems, battery retrofits for compatible existing systems, and EV chargers. For Illawarra businesses such as workshops, offices and retail premises, we look at daytime electricity use, roof space and electrical capacity before recommending a commercial system. If you have an existing system that is showing errors or no longer meets your needs, we can also talk through repair, warranty and replacement options.

Getting started in Wollongong

Request a free quote online or call 02 9090 4861 and let us know your suburb, the type of property and what you are considering. Recent electricity bills and photos of your roof, switchboard and any existing equipment help us prepare. A member of our team will be in touch to talk through the options and arrange a site visit if it suits your project.

How a site visit works

We start with a conversation about your goals and electricity use. Our team then visits to look at the roof, switchboard, meter and possible equipment locations, and answers your questions in person. You receive a written proposal that explains the system, the installation scope and the warranties, so you can decide in your own time.

A Kingsgrove team you can rely on

Our installers are employed by NJC Solar and work from our Kingsgrove base. We explain the proposed system in plain English and remain available after installation for questions and support. Systems purchased directly from NJC Solar include our 15-Year Workmanship Warranty and 5-Year No-Cost System Resolution Guarantee, alongside the separate manufacturer warranties.
