Answer a few quick questions about your home and electricity use. We'll help you explore solar and battery options that make sense for you.
Your Home
Question 1 of 4
Where is your home located?
Your address helps us understand your property's location and potential solar suitability. You can add it later if you'd prefer.
Your Energy
Question 1 of 6
How would you like to tell us about your electricity use?
Whichever's easiest — the more accurate this is, the more accurate your options will be.
My electricity usage (kWh)
Most accurate if you know your usage.
My electricity bill ($)
We'll estimate your usage from your bill.
I'm not sure
You can still explore your options.
Your Energy Options
Three ways to power your home.
Based on what you’ve told us about your household and electricity habits, we’ve put together three options worth exploring.
Essential Energy is the leaner option, Everyday Energy is a middle-of-the-range starting point, and Future Ready Energy adds more solar for what’s ahead.
These are example configurations, not a calculated recommendation. We don't have enough information yet to narrow down a system size — what you see below is a comparison starting point. Adding your actual electricity usage (kWh) or a recent bill amount — the single biggest factor in solar sizing under "Edit answers" would let us calculate a real target.
Essential Energy
A compact solar system to start with.
Solar
6.5 kW
Solar capacity
Designed around your lifestyle
A starting point to compare. Add your electricity usage under “Edit answers” for a tailored size.
Why this system? ▾
We've included this smaller configuration as a starting point. A little more information about your electricity use will help us narrow down the right size.
Your electricity use: We don't have enough usage information yet to size this precisely — a little more detail would sharpen the estimate.
Why this size: This is a smaller configuration, kept here to compare against the other options.

Everyday Energy
Make more of the sun. Rely less on the grid.
Solar
15.8 kW
Solar capacity
Designed around your lifestyle
A starting point to compare. Add your electricity usage under “Edit answers” for a tailored size.
Sits between the smaller and larger options.
Why this system? ▾
We've included this configuration as a starting point. A little more information about your electricity use will help us narrow down the most suitable size.
Your electricity use: We don't have enough usage information yet to size this precisely — a little more detail would sharpen the estimate.
Why this size: This is a starting point for comparison, without enough data yet to narrow things down further.

Equipment notes: A larger array like this needs available roof area, orientation, shading and panel layout verified before it can be treated as available. Confirming your supply phase, inverter AC rating, MPPT/string compatibility and any Western Power export-limit approval matters more at this size — especially since your supply phase isn’t confirmed as three-phase.

More Capacity
Future Ready Energy
More solar generation, with room to grow.
Solar
25.1 kW
Solar capacity
Designed around your lifestyle
A starting point to compare. Add your electricity usage under “Edit answers” for a tailored size.
More capacity than the smaller option, if you’d like extra headroom.
Why this system? ▾
We've included this larger configuration as a comparison point. A little more information about your electricity use will help us narrow down the right size.
Your electricity use: We don't have enough usage information yet to size this precisely — a little more detail would sharpen the estimate.
Why this size: This provides more solar generation and/or battery storage than the smaller configurations, to compare against.

These configurations are indicative and designed to help you explore your options. Final system sizing, equipment compatibility and installation feasibility will be confirmed following a technical assessment of your property.
Your Estimated Energy Outlook
Essential Energy
Estimated solar generation~29 kWh/day
Everyday Energy
Estimated solar generation~71 kWh/day
Future Ready Energy
Estimated solar generation~114 kWh/day
Generation figures are annual daily averages for Perth — higher in summer, lower in winter. We don't estimate bill savings here: that needs your tariff, feed-in rate and when you use power, which we work through in your personalised proposal.

What assumptions are these options based on?
We don’t yet have enough information to calculate a specific target, so these are illustrative catalogue examples to explore rather than a modelled recommendation. The Perth generation figure used throughout (1,650kWh/kW/year) is an annual average for a reasonably-oriented system — actual daily and monthly generation is meaningfully higher in summer and lower in winter. Charging-adequacy estimates based on it describe a typical day across the year, not a guarantee for any specific day or season. A full site assessment (roof suitability, orientation, shading, inverter compatibility, switchboard capacity, network/export approval and actual consumption data) is needed before any of these becomes a final, verified design — that feasibility check is separate from, and doesn't follow automatically from, how confident the energy estimate above is.
FAQs
Common questions
A few things people usually ask at this stage.
Are these the exact systems I'll end up with?
No — they're starting points based on what you've told us, to help you compare directions before a proper site assessment. Your final design is confirmed once we've checked your roof, switchboard and site-specific details.
Why don't I see prices yet?
We'd rather give you a real, accurate number than a guess that changes later. Explore and customise a configuration, then ask for a tailored proposal and we'll follow up directly once we've reviewed your details.
Who carries out the installation?
Our own licensed crew — not a subcontractor network. That's the whole reason Westcoast Energy exists: the people who quote it are the people who build it.
Can I change my answers and see different options?
Yes — use "Edit answers" above at any point, and the options here update to match.
