Solar Installation in Joondalup, Wanneroo and the Northern Suburbs (2026)
Quick answer: As a rough guide, homes in Joondalup, Wanneroo and Perth’s northern suburbs pay around $5,000–$7,500 for a 6.6 kW solar system and $8,000–$11,000 for 10 kW after the STC discount in 2026, the same as the rest of Perth. Most houses do not need council approval. The City of Joondalup says single and grouped dwellings need neither planning approval nor a building permit. The City of Wanneroo exempts rooftop solar on homes where the panels sit parallel to the roof and the property is not heritage-protected.
From Duncraig and Hillarys up to Alkimos, Yanchep and Two Rocks, the northern corridor covers a wide range of homes: established coastal suburbs, 1990s family estates and brand-new subdivisions. Solar works well across all of them. The details that change your quote are local: council rules, how close you are to the ocean, your roof and your switchboard.
How much does solar cost in Joondalup and Wanneroo?
Prices in the northern suburbs follow the Perth market. These are 2026 estimates for installed systems including GST, not quotes:
| System | Rough guide (2026) |
|---|---|
| 6.6 kW solar (after STC) | $5,000–$7,500 |
| 10 kW solar (after STC) | $8,000–$11,000 |
| 13 kW solar (after STC) | $10,000–$14,000 |
| ~10 kWh battery | $9,500–$13,000 before rebates; ~$5,500–$9,000 after federal and WA rebates |
| ~13–16 kWh battery | $13,000–$18,000 before rebates; ~$8,000–$12,500 after federal and WA rebates |
Battery “after rebates” figures assume a Synergy customer receiving the WA rebate and the federal discount. Your price depends on your roof type and height, your switchboard, whether you have single- or three-phase power, and the equipment you choose. A fixed written quote after a site assessment is the only reliable number. Not sure what size you need? Our solar sizing guide walks through it.
Do you need council approval for solar in Joondalup or Wanneroo?
Not for most houses. The two councils word their rules differently, so here is each one.
City of Joondalup
- Single houses and grouped dwellings: no development (planning) approval and no building permit needed for solar panels.
- Multiple dwellings (apartments) and commercial buildings: planning approval is needed where panels are not parallel to the roof, and a building permit is needed for all solar panels.
City of Wanneroo
The City’s Local Planning Policy 4.29 (Renewable Energy Systems) says rooftop solar on a home covered by the Residential Design Codes is exempt from development approval when:
- the panels are parallel to the angle of the roof, and
- the property is not a heritage-protected place.
The policy also asks for non-reflective materials that suit the surrounding area. Tilted frames on a flat or low-pitch roof, ground-mounted arrays and heritage properties may need approval, so check with the City first.
Worth knowing: council rules are not the only ones. Strata properties usually need strata approval because the roof is often common property, and some newer estates have developer design guidelines on things like panel placement. Check both before you book an install date.
What should northern suburbs homeowners check before installing?
Four local factors come up most often.
Coastal exposure
Homes near the ocean in suburbs such as Hillarys, Sorrento, Mullaloo, Ocean Reef, Burns Beach, Mindarie, Quinns Rocks, Alkimos and Two Rocks get salt-laden wind. Ask your installer what corrosion rating the mounting rails, clamps and fasteners have, and check the panel and inverter manufacturers’ conditions for coastal sites. Some warranties set minimum distances from the sea or call for corrosion-rated equipment.
Single-phase or three-phase power
Check your meter box, or ask your installer to. Many newer homes in the corridor have three-phase power, but plenty of established homes are single-phase. It matters because three-phase homes have a higher generation limit (8 kVA per phase vs 15 kVA total on single-phase) under Western Power’s 2026 rules. It also affects battery and EV charger choices.
Roofs and switchboards
Newer estates tend to have Colorbond roofs, simple roof lines and modern switchboards, which keeps installs straightforward. Older homes in suburbs such as Duncraig, Greenwood, Warwick, Craigie and Girrawheen are more likely to have concrete or terracotta tiles and older switchboards that need an upgrade. Double-storey homes, common in coastal suburbs, may need scaffolding. A site assessment should pick all of this up and price it before you commit. If you are building in a new estate, ask your builder whether the switchboard has space for solar and battery circuits. Planning this before handover can save rework later.
Export limits on the edge of the network
Western Power assesses every connection application, and some systems need a technical review before approval. Metro systems within Western Power’s standard limits, using approved equipment, usually do not; rural and small-network sites need a technical study. If yours does need a review, it can add time or come back with an export limit. Your installer should tell you if that applies before installation.

Not sure which council you are in? Your rates notice will tell you. The council matters only for planning rules. Rebates, Synergy tariffs and Western Power’s connection process are the same right across the corridor.
What rebates and tariffs apply in the northern suburbs?
The same Perth-wide incentives apply. The northern suburbs are on Synergy’s retail network and Western Power’s grid, so:
- Solar panels: the federal STC discount comes off your price upfront.
- Batteries: the WA Residential Battery Scheme rebate is up to $1,300 for Synergy customers, on top of the federal Cheaper Home Batteries discount (about $2,600–$2,700 on a 10 kWh battery in 2026). You must join a virtual power plant, and the battery must be on Synergy’s Supported Solutions List.
- Exports: Synergy’s DEBS pays 10c/kWh from 3pm to 9pm and 2c/kWh at other times, capped at 50 kWh a day.
- Tariffs: Synergy’s Midday Saver plan charges 8.85c/kWh from 9am to 3pm, 55.33c from 3pm to 9pm and 24.34c overnight (needs an advanced meter). Households with a battery can often shift more use into the cheap midday window.
See our WA Battery Scheme checklist for the full eligibility rules.
How long does installation take in the northern suburbs?
The same as elsewhere in Perth. The install itself usually takes one day. The overall time depends on the Synergy and Western Power applications, any strata or heritage approval, and the meter change. Our solar installation timeline explains each step.

Frequently asked questions
How much does solar cost in Joondalup or Wanneroo?
As a rough guide, most homes pay around $5,000–$7,500 for a 6.6 kW system and $8,000–$11,000 for a 10 kW system after the STC discount in 2026. A ~10 kWh battery adds roughly $5,500–$9,000 after federal and WA rebates. Your price depends on your roof, switchboard and equipment.
Do I need City of Joondalup approval to install solar panels?
Not for a single house or grouped dwelling. The City of Joondalup says these need neither planning approval nor a building permit for solar panels. Apartments and commercial buildings need a building permit, and planning approval where the panels are not parallel to the roof.
Do I need City of Wanneroo approval to install solar panels?
Usually not for a home. Under the City of Wanneroo’s Local Planning Policy 4.29, rooftop solar on a home is exempt from development approval when the panels are parallel to the roof and the property is not heritage-protected. Tilted frames, ground-mounted systems and heritage properties may need approval.
Does living near the coast affect a solar installation?
It can. Salt spray speeds up corrosion, so ask your installer about the corrosion rating of the mounting rails and fasteners. Also check the panel and inverter manufacturers’ warranty conditions for coastal sites, as some set minimum distances from the sea or need corrosion-rated equipment.
Can I get the WA battery rebate in the northern suburbs?
Yes, if you meet the scheme rules. Synergy customers can get up to $1,300 from the WA Residential Battery Scheme on top of the federal discount. The battery must be at least 5 kWh usable and on Synergy’s Supported Solutions List, and you must join a virtual power plant.
