Coastal Solar Co. installs high-performance solar systems across Wollongong, the Illawarra and the South Coast — with honest pricing, a 5-minute callback guarantee, and a full walkthrough on the day we install.
What South Coast homeowners are saying
“I got three quotes. Coastal Solar was the only company that showed me actual numbers upfront, not just 'call us for a price.' Installed in two days, works perfectly.”
Meredith T.
Kiama
“They called me within 3 minutes of filling in the form. The whole process from quote to install took 8 days. Genuinely impressed.”
Dave K.
Nowra
“After two dodgy quotes, I was nervous. These guys showed up on time, explained everything clearly, and my bill dropped from $480 to $40 per quarter.”

Most solar companies make this harder than it needs to be.
You've probably noticed: you can't get a price without sitting through a 2-hour sales pitch. The guy who quoted you isn't the person who shows up to install. The paperwork is your problem. And after installation — good luck getting anyone on the phone.
We've heard this story hundreds of times from South Coast homeowners. So we built Coastal Solar Co. to do the opposite.
Solar the way it should work.
Honest Pricing
We show you price ranges before you've given us your phone number. A standard 6.6kW system in the Illawarra typically costs $5,500–$7,500 after government rebates.
The 5-Minute Callback
Fill in our form and we'll call you within 5 minutes during business hours — or your first maintenance visit is free.
Install in Days, Not Weeks
From quote to install, we average 6 business days. Most competitors quote 3–6 weeks.
The Full Walkthrough
On installation day, your installer spends 30 minutes walking you through your new system, setting up your monitoring app, and answering every question.

The 2026 solar rebate is the best you'll ever get. It gets smaller every year.
The Federal Government's STC scheme gives you a point-of-sale discount worth $2,800–$3,800 on a standard install. It dropped from 6 to 5 years deeming on 1 Jan 2026. Drops to 4 years in 2027 — another ~17% cut. Plus: Federal Battery Rebate (Cheaper Home Batteries Program, July 2025) gives ~30% off a battery — up to $3,000 savings.
