Honest, practical guides on what solar, battery, hot water and air conditioning actually costs in Australia. Written to help you decide — not to sell you something.
Why some batteries are advertised for thousands less, every major VPP in Australia reviewed honestly (AGL, Origin, Powow, Engie, Energy Australia, Amber, Local Volts), government rebates explained, and real consumer voices — all in one independent guide.
Most solar quotes ignore ducted air conditioning entirely. This guide uses the real engineering formula — zoning, duct age, phase, and climate — to calculate what battery and inverter you actually need. Includes a free 6-step calculator.
Inverter faults are more likely than major blackouts. Here's the honest answer about what happens to your battery, fridge, and critical loads — and the questions nobody asks before signing.
Most quotes don't mention it — but startup voltage determines how early your battery wakes up every morning. Critical for retrofits, older strings, and three-phase systems. Read this before you sign anything.
How much battery do you actually need? This guide cuts through the marketing and gives you a real sizing framework — overnight usage, arbitrage reality, EV load, and inverter shift explained.
Australia's energy market has a hidden cheap window every day — here's how to charge your battery for 2–5¢/kWh and save $1,200+ per year.
Tesla, Sonnen, Enphase, BYD, Alpha-ESS — here's a no-fluff breakdown of which battery suits which home.
Time-of-use tariffs mean Australian businesses can now charge batteries cheaply during the day and avoid expensive peak rates — without a single solar panel on the roof.
Australian SMEs are paying peak rates when the sun is shining. Here's how a battery — with or without solar — changes that equation.
NSW homeowners are set to receive significantly higher solar incentives from 2026. Here's what the rebate boost means for your payback period.
The Federal Government's $5 billion commitment to renewable energy includes measures that will affect solar panel pricing and grid access for Australian homeowners.
Most Australian households pay the same rate for electricity no matter when they use it. Smart households don't — here's how they use the grid's price swings to their advantage.
A solar panel generates power. An EMS decides what to do with it — and that distinction is worth thousands of dollars over a system's lifetime.
Australian electricity bills are among the highest in the developed world. Understanding why — and how pricing actually works — is the first step to paying less.
Most Australians pay their electricity bill without understanding what they're actually paying for. This guide breaks down every line item so you can spot waste and negotiate a better deal.
Virtual Power Plants (VPPs) let your home battery earn money by selling stored energy to the grid during peak demand. Here's how they work, what you'll actually earn, and the trade-offs to consider.
Bigger isn't always better when it comes to solar. This guide shows you exactly how to calculate the right system size for your home, your bill, and your future plans.
Not all solar panels are created equal. This guide compares the top brands available in Australia — Trina, REC, Jinko, Canadian Solar, and LONGi — across efficiency, warranty, and real-world durability.
Battery storage is the fastest-growing home energy technology in Australia. This guide covers everything from chemistry to cost to whether it will actually save you money.
Three of Australia's most popular home battery brands compared side-by-side on price, performance, backup capability, and long-term reliability.
Choosing between ducted and split system air conditioning is one of the biggest decisions in a home renovation or new build. This guide breaks down the real costs, comfort differences, and long-term considerations.
Heat pump hot water systems use 60–75% less electricity than conventional electric storage systems. Here's everything you need to know before switching.
STCs are the federal solar rebate that reduces the upfront cost of your solar or hot water system. Here's exactly how they work, what they're worth, and why installers discount them at point of sale.
Victoria's Victorian Energy Upgrades program offers some of the most generous energy efficiency incentives in Australia. This guide covers everything from heat pumps to insulation to what's actually worth claiming.
Commercial solar offers businesses some of the best returns of any capital investment available today — often 20–40% IRR. Here's how to assess whether it makes sense for your situation.
GoodWe ESA vs FoxESS H1/H3 + EQ4800 — a practical Australian comparison covering blackout protection, safety engineering, app usability, backup power, pricing and who each system actually suits.
Ducted air conditioning costs $8,050–$25,000+ fully installed in Australia. This guide covers what drives the price, state-by-state variations, and how to budget accurately.
A bedroom split system costs $1,800–$2,500 installed in most capitals. Larger living area units run $2,500–$4,800. This guide explains what affects the price and how to compare quotes.
The sticker price rarely tells the full story. Extended pipe runs, wall drops, coastal coatings, switchboard upgrades, and scaffolding can add thousands. Here's what to budget for.
Split systems cost $1,800–$4,800 installed in Melbourne. Ducted runs $8,050–$25,000+. Victoria has the most complex AC licensing in Australia — VBA, ESV, and ARCtick all apply.
Split systems cost $1,800–$4,800 installed in Sydney. Ducted runs $8,050–$25,000+. NSW licensing, coastal salt air, and the Energy Savings Scheme explained.
QLD's heat loads are higher than southern states — upsizing is common. Split systems $1,800–$4,800. Ducted from $8,050. Tropical, coastal, and licensing factors all covered.
SA summers regularly exceed 40°C — ducted is the most popular choice. Split systems $1,800–$4,800 installed, ducted from $8,050. SA sizing requirements and rebates explained.
A split system cooling one room beats ducted every time. But whole-home zoned ducted can match multiple splits. The real answer depends entirely on how much of the house you condition and how often.
A fair AC quote is written, itemised, and includes the unit model, capacity, installation variables, and compliance certificates. Red flags, green flags, and how to compare multiple quotes explained.
The 125 W/m² rule gives you a starting point. A 20m² bedroom needs ~2.5kW. A 40m² lounge needs ~5kW. But orientation, ceiling height, and insulation all change the number.
