Annandale homeowners are quietly paying some of Queensland's highest electricity bills. Ergon Energy's Tariff 11 in Townsville sits at $0.3536 per kWh including GST — that's 35.4 cents every time you run the dishwasher, charge the car, or run the air con through a North Queensland summer. For the average Annandale household drawing 20–25 kWh per day, that adds up to $2,500–$3,200 per year — before prices rise again next financial year. Most households accept this as a fixed cost of living. It doesn't have to be.
The problem isn’t just the cost — it’s the unpredictability. Ergon tariffs have increased every year for the past decade (source: wattever.com.au). A family in Annandale who budgeted $2,800 per year in electricity in 2020 is now looking at $3,500+. Air conditioning is non-negotiable in Townsville’s climate, and with summer temperatures regularly hitting 35°C+, discretionary use isn’t an option. The grid is the only supplier — and it sets the price. Homeowners who installed solar 3–4 years ago are now watching their neighbours’ bills climb while their own sit near zero.

Solar in Annandale works exceptionally well. According to 2024 Open-Meteo solar radiation archive data, Annandale receives an average of 5.40 peak sun hours (PSH) per day — with November peaking at 6.98 PSH and the winter low in July at 4.20 PSH. Even in Townsville's worst solar month, panels are generating strong output. A 6.6kW system on a north-facing roof in Annandale generates approximately 13,000–13,500 kWh per year. At Ergon's current Tariff 11 rate, that offsets $4,600–$4,800 of electricity costs annually.
The right system for Annandale depends on your roof and usage profile. For most 3–4 bedroom homes drawing 20+ kWh/day, a 6.6kW system with 16–20 Tier 1 panels (typically 370–415W each) is the entry point. Panels worth considering: REC Alpha Pure, Jinko Tiger Neo, or Longi Hi-Mo 6 — all Tier 1 rated, all backed by 25-year performance warranties. For battery storage, the GoodWe ESA (5kWh, expandable to 15kWh) is a strong fit for Townsville’s usage patterns — it handles afternoon peak loads well and provides backup through wet season storms. Hardware selection matters less than installation quality and system design.

Frequently Asked Questions — Solar in Annandale

For a typical 3–4 bedroom home in Annandale using 20–25 kWh per day, a 6.6kW system with 16–20 Tier 1 panels is the right starting point. Annandale receives 5.40 peak sun hours per day on average (2024 Open-Meteo data), so a 6.6kW system generates approximately 13,000 kWh per year — enough to offset most or all of a household bill at Ergon's Tariff 11 rate of $0.3536/kWh.

Yes — Annandale is one of Queensland's better solar locations. The suburb receives 5.40 peak sun hours per day annually, with a peak of 6.98 PSH in November and a winter low of 4.20 PSH in July. Even in winter, Townsville's solar resource significantly outperforms southeast Queensland averages. Ergon's relatively high Tariff 11 rate ($0.3536/kWh) also increases the financial return compared to SEQ households on Energex tariffs.

A fully installed 6.6kW solar system in Annandale typically costs $8,500–$11,000 before the Queensland STC rebate. After the rebate (approximately $2,000–$2,500 depending on system size and current STC price), the net cost is typically $6,500–$8,500. Prices vary by panel brand, inverter type, and roof complexity. Source Energy Group provides fixed-price quotes after a site assessment.

Most Annandale homes on Ergon Tariff 11 see payback in 4–6 years. A 6.6kW system generating ~13,000 kWh/year offsets approximately $4,600 of Ergon costs annually at the current $0.3536/kWh rate. At a net system cost of $7,000–$8,000, that's a 4.5–5.5 year payback — followed by 15+ years of near-zero electricity costs.

Battery storage is optional but increasingly popular in Townsville. Annandale experiences wet season storms and occasional grid outages, making battery backup valuable beyond the financial case. The GoodWe ESA (5kWh, expandable to 15kWh) is a reliable option for households wanting backup capability. Without batteries, excess solar exports to the Ergon grid at the current feed-in tariff. With batteries, you store that excess for evening use instead.

After installation, your system is registered with Ergon and begins exporting excess generation back to the grid at the current feed-in tariff. Our team handles the Ergon paperwork, the metering upgrade (if required), and the CEC compliance certificate. Most Annandale systems are operational within 2–4 weeks of signing. We provide a 25-year workmanship warranty on all installations, panel manufacturer warranties of 25 years, and inverter warranties of 10 years. For questions after installation, contact our Townsville support line.
