Home solar panels are photovoltaic (PV) systems that convert sunlight into electricity for your home. In Australia, a standard 6.6 kW system costs between $5,000 and $8,000 after government rebates. Solar Run provides expert solar panel installation in Adelaide and Sydney, with GoodWe battery storage starting from approximately $4,500 installed. Most Australian households recover their investment in 3–5 years and save between $1,500 and $2,500 annually on electricity bills.

Electricity prices in Australia have never been higher — and neither has the incentive to switch to solar. With federal rebates, state government schemes, and panel technology advancing every year, installing home solar panels has become one of the smartest financial decisions an Australian homeowner can make.
At Solar Run, we’ve helped thousands of families across Adelaide and Sydney take control of their energy bills. In this guide, we cover everything you need to know: how solar works, what installation costs in your city, and how GoodWe battery storage can take your savings even further.

How Home Solar Panels Work
Solar panels — also called photovoltaic or PV panels — are made up of silicon cells that absorb photons from sunlight and generate a flow of electrons, producing direct current (DC) electricity. An inverter converts this DC power into alternating current (AC), which is the type your appliances and lights run on.
Any electricity your panels produce that your home doesn’t immediately use is either exported to the grid (earning you a feed-in tariff credit on your bill) or stored in a battery for use after dark.
The two most common panel types Solar Run installs are:
Monocrystalline panels — the premium choice, with efficiency ratings of 19–23%. These are ideal for homes with limited roof space because they produce more power per square metre.
Polycrystalline panels — a more budget-friendly option with slightly lower efficiency (15–17%), well-suited to larger rooftops with generous north-facing exposure.

☀️ Solar Run Expert Tip — The North-Roof Rule: In Australia, panels face north to receive maximum sun exposure year-round. A roof facing east or west can reduce system output by 10–15%. Always request a shading and orientation analysis from your installer before committing to a design.

Solar Panel Installation in Adelaide: What You Need to Know
Adelaide is one of the sunniest capital cities in Australia, averaging 4.9 peak sun hours per day. That means your panels work harder here than almost anywhere else in the country — and your savings reflect it.
A quality 6.6 kW solar panel installation in Adelaide costs approximately $5,000–$7,000 after applying federal Small-scale Technology Certificates (STCs). The state government’s Home Battery Scheme also provides subsidised loans for battery storage, reducing the cost of a GoodWe battery by up to $2,000 for eligible households.
Average annual savings for Adelaide homeowners with a 6.6 kW system sit between $1,800 and $2,200, driven by the city’s high electricity rates (around 40 cents per kWh) and abundant sunshine.

☀️ Solar Run Expert Tip — Beat the Summer Peak: Adelaide summers are intense. Sizing your battery to store midday solar excess means you can power your air conditioning through the expensive 4–8 PM peak pricing window entirely from stored solar. A 10 kWh GoodWe battery is the sweet spot for most 3-bedroom Adelaide homes.

Solar Run is CEC-accredited and manages all SA Power Networks approvals, permits, and connection paperwork in-house — so your system goes live faster with less stress on your end.

Solar System Installation in Sydney: Local Expertise That Matters
Sydney averages 4.5 peak sun hours per day, with western suburbs outperforming the coastal areas due to lower cloud cover. A 6.6 kW solar system installation in Sydney typically costs $5,500–$7,500 installed after rebates.
NSW homeowners may also be eligible for the Empowering Homes Program, which offers interest-free loans of up to $14,000 for combined solar and battery systems — significantly reducing the upfront investment.
What makes Sydney installs unique is the variety of roof types across the city. Older homes in the inner west and north shore often feature terracotta or concrete tile roofs, which require specialised mounting hardware and slightly more complex installation.

☀️ Solar Run Expert Tip — The Tile Roof Factor: Tile roofs can add $200–$500 to installation costs due to the brackets required. Solar Run includes a free structural and roof assessment with every Sydney quote so you’re never surprised by unexpected costs on the day.

Solar Run’s Sydney team has completed over 3,000 residential installations across Greater Sydney, from Penrith to Parramatta to the Northern Beaches.

GoodWe Battery Price Guide 2026
Adding battery storage transforms a standard solar system into a near self-sufficient home energy setup. Solar Run recommends GoodWe batteries for their reliability, competitive pricing, and seamless compatibility with GoodWe inverters.
Here’s what GoodWe battery storage costs in Australia in 2026 (installed):
ModelCapacityInstalled Price (AUD)GoodWe Lynx Home F5 kWh~$4,500–$5,500GoodWe Lynx Home U10 kWh~$7,500–$9,000GoodWe Lynx Home U15 kWh~$10,500–$12,500GoodWe Lynx Home U20 kWh~$14,000–$16,500
All GoodWe batteries supplied by Solar Run carry a 10-year performance warranty, guaranteeing at least 80% capacity retention.

☀️ Solar Run Expert Tip — The Two-Second Rule for Battery Sizing: Here’s a quick formula: divide your average daily electricity usage (in kWh) by two. That’s your minimum recommended battery size. A household using 20 kWh per day needs at least a 10 kWh battery to cover overnight demand from solar stored during daylight hours. Solar Run refines this estimate using actual data from your electricity bills.

☀️ Solar Run Expert Tip — The Neutral Spine Advantage: The most efficient home energy setup pairs a 6.6 kW solar system with a 10 kWh GoodWe battery. This combination creates what our engineers call a “neutral energy spine” — your home neither wastes excess solar by exporting it at low feed-in rates, nor draws heavily from the grid at peak prices. Households with this setup typically reduce electricity bills by 85–95%.

Is Home Solar Worth It in 2026?
Absolutely. With electricity prices rising and panel costs continuing to fall, the economics of home solar panels have never been more compelling. Factor in government rebates, feed-in tariff credits, and the added value a solar system adds to your property, and the case becomes even clearer.
Most Solar Run customers in Adelaide and Sydney see payback periods of 3–5 years and go on to generate effectively free electricity for the remaining 20+ years of their system’s life.
