Solar has been talked about, marketed and oversold so relentlessly over the last decade that a lot of Noosa Hinterland homeowners have quietly tuned out. The messaging is exhausted. 'Free power from the sun!' 'Pays for itself in five minutes!' 'Rebates ending soon!' Meanwhile the actual answer — whether solar is worth installing on your particular roof, in your particular town, with your usage pattern — depends on a handful of specific numbers that most quoting salespeople don't want to spend time on.
This post walks through the actual maths for a typical Pomona, Cooroy or Noosa Hinterland home in 2026: current solar system costs, feed-in tariffs, self-consumption rates, battery payback, and the honest trade-offs between size, cost and outcome. If you've been sitting on 'we should probably get solar' for three years, read this and decide.
For most Noosa Hinterland, Cooroy, Pomona and Sunshine Coast homeowners in 2026, a properly sized solar system still pays for itself inside 4-6 years, then saves you money for another 20+ years. But the honest answer isn't "yes, always" — it depends on your roof, your usage, and whether you add batteries. Let's walk through the actual numbers for properties across Pomona, Cooroy, Noosaville, Tewantin, Eumundi, Doonan and the wider hinterland.
A quality 6.6kW solar system installed professionally by a licensed electrical contractor typically costs between $6,500 and $9,500 including the federal STC rebate. A 10kW system runs $9,000-$13,000. Going up to 13.3kW (the maximum for most single-phase homes) sits around $12,000-$16,000. Price varies with panel brand, inverter quality, roof complexity and your switchboard's readiness for solar.
At Ultralec we recommend quality-tier panels (Canadian Solar, Jinko Tiger, REC) paired with quality inverters (Fronius, SMA, Sungrow) — not the cheapest panels on the market. Our reasoning: the panels are on your roof for 25 years, and saving $1,500 upfront to then replace a failed inverter in year 6 is false economy.
The big shift in the last few years: feed-in tariffs (what your retailer pays for solar exported to the grid) have dropped dramatically — from 40-50¢ per kWh a decade ago to 4-8¢ per kWh now in Queensland. Meanwhile your import rate (what you pay to buy power) is 28-35¢ per kWh.
What this means practically: self-consuming your solar is now 4-5x more valuable than exporting it. Every kWh you use while your panels are producing saves you the full import rate. Every kWh you export is paid at a fraction of that.
The solar sizing implication is significant. Oversizing a system so it "always exports heaps" used to be the ideal strategy. Now, the goal is to size a system that matches your daytime consumption as closely as possible — and then add batteries if you want to push self-consumption even higher.
The honest answer for most Noosa Hinterland homes: batteries now pay for themselves within 7-10 years, and they're getting cheaper every year. A quality 10-13kWh battery (Tesla Powerwall, Sungrow, SigEnergy, Alpha ESS) costs $10,000-$14,000 installed. If it saves you $1,500-$2,000 per year in grid imports, it's paid back inside a decade — with 10+ years of savings after that.
Batteries also provide backup power during outages — genuinely useful for Pomona, Cooroy, Cooran and acreage properties that lose grid power during storm season. A properly configured battery system with backup capability keeps essential circuits running for 12-24 hours during a grid outage.
If you're planning to buy an electric vehicle in the next few years — or you already have one — solar plus battery plus home EV charger is a genuinely compelling setup. Charging your EV from your own solar (either directly during daylight, or via battery overnight) effectively gives you free kilometres for the life of the system. Ultralec handles the full EV charger installation across the Sunshine Coast.
Not every roof suits solar equally. What we look for when quoting a system for a Pomona, Cooroy or Noosaville home:
Single-phase homes are typically limited to 6.6kW of inverter capacity (with up to 13.3kW of panels under oversizing rules) by Energex. Three-phase homes can go to 15kW of inverter and proportionally more panels. The exact limits depend on your suburb, your network constraint level, and your switchboard.
No — unless you have a battery with backup capability. A normal grid-tied solar system shuts off during a blackout (for safety reasons). Adding a battery with backup mode is how you maintain power during outages.
Yes. Energex will install a smart meter (called a Type 4 meter) as part of the solar grid connection process. There's no charge for this.
Most residential installs take 1-2 days on-site plus 1-3 weeks of paperwork (DNSP pre-approval, meter change, STC rebate processing). Ultralec handles all the paperwork — you just need to sign and send documents.
If you're in Pomona, Cooroy, Noosa, Tewantin, Eumundi, Gympie or anywhere across the Noosa Hinterland, we'd love to quote your solar install. We'll assess the roof, crunch the numbers for your actual power usage, and give you an honest recommendation — including whether solar isn't the right fit, if that's the case.
