Move the sliders to see your estimated savings based on your current energy usage and chosen system.

We've been operating in NSW since 2018. Here's what makes us different from the dozens of solar companies that have come and gone.
Every installation is carried out by a Clean Energy Council accredited installer. This is required by law, but many cowboys cut corners. We never do.
Our team assesses your actual usage data before recommending any system. No overselling, no underselling — just the right solution for your home.
We answer our phones. Our local Parramatta-based team is available for questions, maintenance, and monitoring support after installation.
We handle all government rebate applications on your behalf, across Federal STCs, NSW ESS, and the Empowering Homes Program — ensuring you capture every dollar available.
"Zero Carbonz installed a 10kW solar system plus the Solis battery. My last electricity bill was $6. Six dollars! After spending $400+ a month I genuinely didn't believe it was possible. The team was clean, fast, and explained everything."
"The team handled every rebate for me — I didn't have to do anything except sign the forms. They saved me over $3,000 in government incentives I didn't even know I was entitled to. Absolutely faultless from quote to installation."
"We upgraded our ducted aircon through Zero Carbonz — the rebate knocked $1,200 off the price. New system uses a fraction of the energy. House is cooler in summer, warmer in winter. Should have done this years ago."
"I was sceptical of solar companies after hearing horror stories but Zero Carbonz were completely transparent. They showed me my actual usage data, explained exactly what system I needed, and didn't try to upsell me. Refreshing."
"Running a small business in Western Sydney and our power bills were crippling us. Zero Carbonz did a commercial solar installation in two days. Bills dropped by 78% in the first month. This is the best business investment I've made."
"Quick, professional, and genuinely nice people to deal with. They finished our solar and battery install in one day, cleaned up everything, and walked us through the monitoring app. Already seeing the savings on our first bill."
A panel-only system typically saves 60–70% off your electricity bills during daylight hours. Adding a battery increases savings to up to 90% by storing unused solar energy for night-time use. The exact amount depends on your energy usage, roof orientation, and chosen system size.
Yes — multiple schemes are available. The Federal STC scheme provides upfront rebates of up to $4,500 on new solar systems. The NSW Energy Savings Scheme (ESS) covers battery storage, heat pump hot water, and aircon upgrades. The Empowering Homes Program offers interest-free loans up to $14,000. We handle all applications on your behalf.
Most residential solar installations are completed in a single day. Battery storage is typically added in 2–4 hours. Hot water and aircon upgrades are usually half a day each. Commercial projects may take 2–5 days depending on system size. We'll give you an exact timeline during your free assessment.
This depends on your household's energy usage. As a guide: a 2-bedroom home typically needs 6–8kW, a 3–4 bedroom home needs 10–13kW, and larger homes or those with pools or EVs may need 15kW+. We'll review your actual electricity bills and recommend the right size — never more than you need.
Yes. The Solis battery qualifies under the NSW Energy Savings Scheme and may also be eligible under the Empowering Homes Program for an interest-free loan. Our team confirms your eligibility during the free quote and handles all applications on your behalf.
