Frequently Asked Questions

Should I Install a Battery With My Solar System?

A battery may be worthwhile if you have excess solar power during the day, use a lot of electricity after sunset, pay high peak rates, or want backup power during outages. However, not every battery provides blackout protection. The system must be designed and configured for backup.

Before buying, ask the installer to study 12 months of electricity bills or smart-meter data. The quote should show the battery’s usable capacity, backup circuits, continuous power, surge power, warranty, expected savings, and estimated payback period. According to the Australian Government battery guide (https://www.energy.gov.au/solar/get-know-solar-technology/batteries), a battery only makes sense when there is enough excess solar electricity to store.

Do Cyclones Affect Solar Systems in Townsville?

Yes. Townsville City Council confirms that Townsville is in a tropical cyclone region. Solar panels, rails, clamps, roof attachments, and fixings must be selected and installed for the property’s wind conditions.

Ask the installer to record the wind region, roof type, building height, mounting system, fixing spacing, and relevant engineering requirements in the system design. A general claim that a system is “cyclone-rated” is not enough without a mounting plan for your property. Learn more from Townsville City Council (https://www.planning.townsville.qld.gov.au/preparing-and-submitting-a-development-application/building-and-renovating) and the National Construction Code (https://ncc.abcb.gov.au/editions/ncc-2022/adopted/volume-one/b-structure/part-b1-structural-provisions).

How Many Quotes Should I Get From Solar Power Firms?

Get at least three detailed solar quotes where possible. According to the Australian Government Solar Consumer Guide (https://www.energy.gov.au/solar/solar-retailers-and-installation/choose-your-solar-retailer-and-installer), homeowners should ask for quotes from at least three suppliers and request a site visit.

Give each company the same electricity bills, roof information, and battery plans. This lets you compare similar systems instead of comparing three completely different offers. The cheapest quote may cost more later if it leaves out switchboard work, network requirements, quality mounting, monitoring, or after-sales support.

Are Solar Panels Worth It in Townsville?

Solar panels can be worthwhile in Townsville when the system matches your electricity use, roof, tariff, and daytime consumption. According to energy.gov.au (https://www.energy.gov.au/solar/get-know-solar-technology/solar-panels), 1kW of solar panels can generate about 3.5kWh to 5kWh per day across Australia, averaged over a year. Using that broad range, a 6.6kW system could generate roughly 23kWh to 33kWh per day before site-specific losses.

This is a guide, not a guaranteed Townsville result. Your written quote should include a monthly and annual production estimate based on your roof direction, pitch, shading, local weather, panel temperature, inverter losses, export limit, electricity tariff, and expected self-consumption.

Is 10kW Solar Enough to Run a House?

A 10kW solar system can cover a large share of the electricity used by many homes, but the answer depends on when and how the home uses power. Using the Australian Government’s broad production range, 10kW of panels could generate roughly 35kWh to 50kWh per day when averaged across a year. Actual output will change with the roof, weather, shading, equipment, and season.

Check your daily kWh use, daytime consumption, air conditioning, pool equipment, electric vehicle plans, battery size, supply phase, and export limit. Ergon Energy currently lists a maximum 10kVA inverter capacity and a 5kW fixed export limit for many basic single-phase connections. Dynamic connections may allow different export levels depending on the network and approved equipment. Check the current Ergon Energy connection requirements (https://www.ergon.com.au/network/our-services/connections/residential-and-commercial-connections/solar-connections-and-other-technologies/dynamic-connections-for-energy-exports/dynamic-connections-for-installers) before accepting a design.

What Is the 20% Rule for Solar?

There is no single official Australian “20% rule” that applies to every solar system. Some people use the term as an informal planning guide for adding extra capacity for future electricity use. Others use it when discussing the difference between solar panel capacity and inverter capacity.

If the term refers to panel and inverter sizing, 20% is not the standard limit. The Australian Government solar sizing guide (https://www.energy.gov.au/solar/solar-system-design/size-your-solar-system) gives 6.6kW of panels on a 5kW inverter as a common example. That panel capacity is about 32% higher than the inverter rating. The final ratio must follow the inverter manufacturer’s specifications, network approval, installation standards, and government rebate rules. Ask anyone using the phrase “20% rule” to explain exactly what they mean in writing.

What Size Solar System Is Best for a Family Home?

The right size starts with your average daily electricity use. The following ranges are useful starting points, not final system designs:

- Up to 15kWh per day: Compare systems around 5kW to 6.6kW.

- About 15kWh to 25kWh per day: Compare systems around 6.6kW to 10kW.

- More than 25kWh per day: Compare 10kW to 13.2kW or larger systems where the roof and network allow.

Your installer should also review when you use electricity. A family using most of its power at night may need a different design from a family running air conditioning, a pool, hot water, or an electric vehicle during the day. According to energy.gov.au (https://www.energy.gov.au/solar/solar-system-design/size-your-solar-system), smart-meter interval data provides the most accurate picture of how much electricity you use and when you use it.

This estimate uses average solar production of 4.5kWh per day for every 1kW of panels. This sits within the Australian Government’s broad range of 3.5kWh to 5kWh per day for each 1kW of solar capacity. Actual Townsville production depends on roof direction, roof pitch, shading, panel temperature, weather, inverter losses, maintenance, and network export limits. See the Australian Government solar panel guide (https://www.energy.gov.au/solar/get-know-solar-technology/solar-panels).

The example uses Ergon Energy’s Tariff 11 rate from 1 July 2026 and the 2026–27 regional Queensland feed-in tariff. Electricity rates, feed-in tariffs, household usage, and solar production can change.

Self-consumption makes a major difference. If this home used only 30% of its solar electricity directly, estimated annual savings would fall to about $2,114. If it used 60% directly, estimated savings could rise to about $3,242. Running pool pumps, hot water, appliances, and electric vehicle charging during solar hours may increase self-consumption.

This estimate does not include the solar purchase price, financing costs, system degradation, maintenance, repairs, controlled-load tariffs, rebates, or future electricity price changes. Request a site-specific production and savings estimate before making a financial decision.

What Should I Compare When Getting Solar Quotes?

Compare the complete design, not just the price or total system size. Each written solar quote should clearly show:

- The exact solar panel brand and model

- The exact inverter or microinverter brand and model

- The battery brand, model, usable capacity, and backup ability

- The mounting system and wind-design requirements

- The proposed panel, inverter, and battery locations

- The estimated monthly and annual electricity generation

- Every assumption used for the savings estimate

- The panel, inverter, battery, performance, and workmanship warranties

- The monitoring system and any ongoing fees

- Switchboard, meter, cabling, or mains upgrades

- Network connection and export limits

- All exclusions and possible extra charges

- The local after-sales and fault-support process

The Australian Government Solar Consumer Guide (https://www.energy.gov.au/solar/solar-retailers-and-installation/choose-your-solar-retailer-and-installer) recommends checking these details before signing a contract. Any verbal promise that matters should also appear in writing.

How Do I Choose a Solar Installer in Townsville?

Choose an installer who studies your roof, switchboard, electricity use, future plans, and Ergon Energy connection requirements before recommending a system. Check the individual installer’s Solar Accreditation Australia accreditation and electrical licence. Also compare local technical support, product approvals, workmanship, warranties, written exclusions, monitoring, and fault response.

O'Brien Electrical & Solar Townsville Central is a locally operated business backed by a national network. Approved network figures include a history dating to 1926, 165,000+ panels installed across Australia, 10,000+ completed solar installations, and more than $9.1 million returned to customers through energy savings. These figures provide useful background, but you should still compare the site-specific design, written warranties, expected generation, and after-sales support included in your quote.

According to the Australian Government (https://www.energy.gov.au/solar/solar-retailers-and-installation/choose-your-solar-retailer-and-installer), an accredited local installer with accessible after-sales support can be valuable, especially in regional areas.

Final Thoughts

Choosing a solar installer is about more than finding the cheapest price.

Homeowners in Townsville, Kirwan, Annandale, Douglas, North Ward, and Bushland Beach should focus on installation quality, warranty backing, cyclone readiness, repair capability, and long-term accountability.

A solar system may last decades. The company supporting it should be able to do the same. This applies whether you are comparing providers for a new system, upgrading existing equipment, or planning future battery storage.
