Common questions
What others asks before signing up?
How much does a solar hot water system cost in Australia?
A typical solar hot water system costs between $3,500 and $8,500 installed, depending on system type, tank size, and whether you need gas boost or old system removal. Close-coupled systems start around $3,500, while split systems with larger tanks can reach $7,500 before rebates.
What rebates are available for solar hot water?
Federal Small-scale Technology Certificates (STCs) apply to all solar hot water and heat pump systems — typically worth $600–$1,200 depending on your zone and system. Victoria also offers a $1,000 Solar Homes hot water rebate. This calculator factors in both.
How accurate is this solar hot water calculator?
This calculator produces an estimate based on typical Australian installed prices for each system type and tank size. Your plumber will confirm the final price after a site assessment — factors like roof pitch, pipe runs, and switchboard upgrades can affect the installed cost.
Is solar hot water worth it compared to electric?
Most households save $400–$800 per year on electricity by switching from a standard electric tank to solar hot water or a heat pump. Typical payback is 5–8 years depending on your system, household size, and electricity rate.
Can I add this calculator to my WordPress or Webflow site?
Yes. Copy the embed code from your Leadkit dashboard and paste it into any page on WordPress, Webflow, Squarespace, Wix, or Shopify. The calculator loads in an iframe and matches your site's branding.
What do I get when a homeowner fills out the calculator?
You get an instant notification with the homeowner's name, contact details, location, system preferences, and a lead score. A branded PDF estimate is sent to the homeowner automatically — you just follow up.
What if I don't have a website?
Leadkit generates a hosted quote page for every calculator. Share the link on social media, Google Business, or in messages — no website needed.
Is Leadkit really free?
Yes. Free lets you add up to 3 calculators to your website and receive 10 leads per month — no credit card. Every lead beyond the cap is still captured and held for you; upgrading to Pro ($29/mo) opens them all retroactively and removes the cap.
Do I need to know how to code?
No. You get an embed code (one line of HTML). Paste it into your website builder — Wix, Squarespace, WordPress, or any custom site. That's it.
How accurate are the price estimates?
You configure the calculator formulas to match your actual pricing. Leadkit provides the framework; you set the numbers. Estimates can be as detailed or as rough as you like.
What happens with lead data?
All lead data is stored securely in your workspace. You own it. We never sell or share your leads with anyone.
Can I use Leadkit as an agency for multiple clients?
Yes — our Agency plan lets you create and manage separate workspaces for each of your clients, all from one dashboard.
What's the difference between the plans?
Free: up to 3 calculators, 10 leads/month (over-cap leads held + locked until upgrade). Pro: unlimited leads, unlimited calculators, white-label, branded email sending, analytics, email templates. Agency: everything in Pro plus multi-workspace management.

How it works
How this solar hot water calculator is calculated
This calculator produces an estimate, not a binding quote. Final pricing depends on site assessment, pipe runs, and switchboard requirements.
GST handling: GST (10%) is included in the total. Rebates are applied before GST as they reduce the purchase price.
1
Base system cost
The calculator starts with average installed prices for each system type — close-coupled solar, split system solar, or heat pump — sourced from Australian installer data.
system_type + tank_size
2
Tank and backup upgrades
Upgrading from a 250L to a 315L or 400L tank adds a size premium. Choosing gas boost over electric adds the cost of gas plumbing and a gas-compatible unit.
3
Site factors
Difficult roof access (two-storey, steep pitch, or tight access) adds a surcharge. Old system removal includes disconnection, removal, and disposal.
4
Rebates applied
Federal STCs are calculated using the current STC spot price and the zone-based certificate count for solar hot water systems. Victorian installs also deduct the Solar Homes hot water rebate ($1,000).
stc_count * stc_price + state_rebate
5
GST and total
GST at 10% is applied to the net installed cost after rebates. The calculator also estimates annual energy savings and payback period based on average kWh displacement.
