Why Get 3 Solar or Heat Pump Quotes?

A solar or heat pump quote is about more than the price.

Two installers can assess the same property and recommend completely different systems — with significantly different equipment, installation inclusions, warranties and prices.

For example, one solar installer might recommend a 6.6kW solar system, while another recommends a larger system based on your electricity usage, roof space and future energy requirements.

Similarly, one heat pump installer may recommend a 200L system, while another recommends 250L or 300L.

The cheapest quote isn’t automatically the best quote.

Comparing three detailed quotes helps you understand what you’re actually getting for your money.

Comparing quotes can help you:

  • Understand the realistic installed price
  • Compare different brands and models
  • Check whether the system is correctly sized
  • Identify installation costs hidden in the fine print
  • Understand rebates and STCs
  • Compare warranties and after-sales support
  • Compare battery options and usable capacity
  • Understand how solar can work with your battery or heat pump
  • Avoid paying for equipment you don’t actually need
  • Choose an installer based on value, not just price

What Does a Solar or Heat Pump System Cost in Australia?

There is no single price that applies to every property.

Your final installed price can depend on your property, energy usage, equipment selected and installation requirements.

For solar, the price can depend on:

  • Solar system size
  • Panel brand and model
  • Inverter brand and capacity
  • Roof size, orientation and accessibility
  • Single-phase or three-phase power
  • Switchboard requirements
  • Roof type
  • Battery storage
  • Installation complexity
  • Applicable rebates and STCs

For heat pumps, the price can depend on:

  • Heat pump brand and model
  • Tank capacity
  • Installation location
  • Existing hot water system
  • Plumbing requirements
  • Electrical work
  • Removal of the existing system
  • Drainage requirements
  • Applicable rebates and STCs

Don’t compare the advertised price alone.

Consider two solar quotes:

Quote A — $7,500

May include:

  • Solar panels
  • Inverter
  • Basic installation
  • STC discount

But may exclude:

  • Switchboard upgrades
  • Additional electrical work
  • Difficult roof access
  • Monitoring equipment
  • Other installation requirements

Quote B — $8,500

May include all of the above.

The second quote could therefore offer better overall value despite having a higher upfront price.

That’s why you should compare the complete installed system and scope of work, not just the headline price.

What Should Be Included in a Solar or Heat Pump Quote?

A good quote should make it easy to understand exactly what you’re buying.

Quote ItemWhat to Check
System typeWhat solution is being proposed?
BrandWho manufactures the equipment?
ModelWhat exact model is being installed?
System sizeIs it appropriate for your energy usage?
InstallationWhat labour and materials are included?
Electrical workAre switchboard or other upgrades included?
Rebates/STCsWhat incentives have been applied?
WarrantyWhat is covered and for how long?
MonitoringIs monitoring included?
BatteryWhat is the usable capacity and warranty?
Heat pumpWhat tank size and efficiency are offered?
RemovalIs existing equipment removal included?
Final priceWhat will you actually pay?

If a quote doesn’t clearly explain these items, ask questions before signing.

How Our 3-Quote Process Works

Getting started is simple.

1. Tell Us What You Need

Choose what you’re looking for:

  • Solar panels
  • Solar battery
  • Solar + battery
  • Heat pump hot water
  • Solar + heat pump
  • Battery upgrade
  • Existing solar system upgrade

You can also tell us if you’re replacing an existing system.

2. Tell Us About Your Property

Provide basic information such as:

  • Property address
  • Property type
  • Roof type
  • Existing solar system
  • Number of occupants
  • Electricity usage
  • Quarterly electricity bill
  • Battery ownership
  • Hot water system
  • Your main energy goal

The more accurate the information, the more useful your quotes can be.

3. Tell Us What You Want to Achieve

For example:

“I want to reduce my electricity bills.”

Or:

“I have solar and want to add a battery.”

Or:

“My electricity usage has increased and I want a larger solar system.”

Or:

“My existing hot water system is old and I want to replace it with a heat pump.”

Your objective matters because the right system isn’t necessarily the biggest or cheapest one.

4. Compare Up to 3 Quotes

Receive up to three personalised, no-obligation quotes so you can compare your options before choosing an installer.

What Size Solar System Do You Need?

Bigger isn’t always better.

The right solar system depends on how much electricity your household uses, when you use it and how much suitable roof space you have.

Installers may consider:

  • Annual electricity consumption
  • Quarterly electricity bills
  • Daytime vs evening electricity usage
  • Roof size
  • Roof orientation
  • Roof pitch
  • Shading
  • Existing solar system
  • Future electricity requirements
  • Battery plans
  • EV charging
  • Pool and other major energy loads

Ask every solar installer:

“Why are you recommending this system size for my household?”

If three installers recommend significantly different system sizes, ask them to explain the assumptions behind their recommendations.

Solar Panels + Battery: What Should You Compare?

If you’re considering a battery, don’t compare battery prices alone.

Look at:

  • Battery capacity
  • Usable battery capacity
  • Maximum charge/discharge power
  • Battery chemistry
  • Inverter compatibility
  • Backup capability
  • Warranty
  • Warranty cycle or throughput conditions
  • Monitoring
  • Expandability
  • Installation requirements

A battery with a larger advertised capacity isn’t automatically the better option.

The right battery depends on how much electricity you use, when you use it and what you want the battery to achieve.

Ask your installer:

“How much of my electricity usage can this battery realistically cover, and what assumptions are you using?”

Solar + Heat Pump: Can They Work Together?

If you already have rooftop solar, tell your installer.

A heat pump can potentially be scheduled to operate during periods when your solar system is generating electricity.

Instead of:

Solar → Grid

you may be able to use more of your solar generation for hot water:

Solar → Heat Pump → Hot Water → Evening Use

This can help increase solar self-consumption.

Ask your installer whether the proposed heat pump supports:

  • Timers
  • Smart controls
  • Solar-aware operation
  • Remote monitoring
  • Demand management

Don’t assume every heat pump has the same controls or operating features.

How Much Can Solar or a Heat Pump Save?

Be careful with generic savings claims.

Your actual savings depend on your property, energy consumption, electricity tariff, equipment and how the system is operated.

Solar savings can depend on:

  • Electricity usage
  • Solar system size
  • Solar generation
  • Electricity tariffs
  • Daytime energy consumption
  • Export rates
  • Battery usage
  • System orientation
  • Shading

Heat pump savings can depend on:

  • Existing hot water system
  • Hot water consumption
  • Electricity tariff
  • Heat pump efficiency
  • Operating schedule
  • Climate
  • Solar generation

Instead of asking:

“How much will I save?”

Ask:

“What annual energy consumption and savings are you estimating, and what assumptions did you use?”

This gives you a much more useful number to compare between installers.

What Solar Rebates and STCs Should You Check?

Depending on the system and installation, eligible products may qualify for government incentives such as Small-scale Technology Certificates (STCs).

The benefit can vary depending on the:

  • Product
  • System size
  • Location
  • Installation date
  • Eligibility requirements
  • Applicable certificate settings

When comparing quotes, don’t assume the advertised price is directly comparable.

Ask every installer:

“What rebates or STCs have been applied to this quote, and what would the price be without them?”

This helps you understand the actual value of each offer.

Don’t Forget Installation Costs

The equipment is only part of your solar or heat pump investment.

Installation requirements can make a significant difference to the final price.

Solar installation may involve:

  • Roof access
  • Roof mounting
  • Electrical cabling
  • Switchboard work
  • Metering
  • Inverter location
  • Additional safety requirements
  • Scaffolding or specialised access

Heat pump installation may involve:

  • Plumbing modifications
  • Electrical work
  • Existing system removal
  • Drainage
  • Mounting/base requirements
  • Relocation of the unit
  • Difficult access

A quote that looks cheaper initially may become more expensive if important installation requirements are excluded.

Where Will Your Equipment Be Installed?

Installation location matters.

For solar equipment, consider where the inverter and battery will be positioned.

For a heat pump, consider the location of the outdoor unit.

Ask:

“Where exactly will the equipment be installed?”

Consider proximity to:

  • Bedrooms
  • Living areas
  • Windows
  • Neighbours
  • Outdoor entertaining areas
  • Existing electrical equipment

The cheapest installation location isn’t always the best location for long-term convenience.

Compare Solar and Heat Pump Warranties Properly

Don’t simply choose the quote that says:

“10-year warranty.”

Find out what that warranty actually covers.

Check separately:

Equipment warranty
How long is the equipment covered?

Inverter warranty
What does the inverter warranty cover?

Battery warranty
What are the capacity, cycle and performance conditions?

Heat pump warranty
What are the tank and compressor warranty periods?

Parts warranty
Are electronic and mechanical components covered?

Labour warranty
Does the installer cover labour?

Call-out costs
Could you still pay for diagnosis or repairs?

Warranty conditions
Are there installation, servicing or maintenance requirements?

10 Questions to Ask Every Solar or Heat Pump Installer

Before choosing your quote, ask each installer the same questions.

  1. Why are you recommending this system?
  2. Why is this system size suitable for my property?
  3. What brands and exact models are included?
  4. What is included in the installation price?
  5. Are electrical, plumbing and other additional costs included?
  6. What rebates or STCs have been applied?
  7. What are the equipment and installation warranties?
  8. What annual energy production or consumption are you estimating?
  9. Where will the equipment be installed?
  10. What will my final out-of-pocket price be?

Asking every installer the same questions makes it much easier to compare quotes apples-to-apples.

Solar & Heat Pump Quote Comparison Checklist

When your quotes arrive, don’t immediately choose the cheapest one.

Compare each quote against the same criteria:

FactorQuote 1Quote 2Quote 3
Final installed price
Brand & model
System size
Panel/inverter/heat pump specifications
Battery capacity
Estimated energy performance
Rebates/STCs
Installation inclusions
Electrical/plumbing work
Existing system removal
Warranty
Monitoring/controls
Installer experience
Estimated installation date

This turns three potentially confusing quotes into an apples-to-apples comparison.

Red Flags to Watch For

Be cautious if a quote:

🚩 Doesn’t show the exact equipment model

🚩 Gives only a headline price

🚩 Doesn’t clearly explain rebates or STCs

🚩 Doesn’t specify the system size

🚩 Doesn’t explain installation inclusions

🚩 Makes unrealistic savings promises

🚩 Doesn’t explain warranty coverage

🚩 Leaves major electrical or plumbing costs unclear

🚩 Pressures you to sign immediately

🚩 Can’t explain why a particular system was recommended

A good installer should be able to clearly explain what they’re recommending, why they’re recommending it and what you’re paying for.

Is the Cheapest Solar or Heat Pump Quote the Best?

Not necessarily.

The better question is:

“Which quote gives me the best long-term value?”

A slightly more expensive system may offer:

  • Better equipment
  • Higher efficiency
  • Better warranty
  • Better monitoring
  • Better battery performance
  • Better installation
  • Better after-sales support

At the same time, more expensive doesn’t automatically mean better.

That’s why comparing several detailed quotes is valuable.
