Savings are guaranteed for rightly sized systems once the investment has been recovered through savings on lower energy bills. As there are minimal ongoing costs, your system will produce power for free, leading to additional household savings.

Small Scale Technology certificates (STC’s) are a financial incentive to reduce the upfront cost of solar for systems up to 100 kW. It is often termed as the “solar rebate” but in real terms, it is more of a financial incentive. Its purpose is to provide upfront discounts upon the total price of the system. All prices quoted by Z4E include this STC discount. Values decline yearly every 1st of Jan until 2030.

Feed-in tariffs are what your electricity retailer pays per kWh solar exported back into the grid. Typical 2026 values: 4.8-7.3c/kWh in NSW, varying by provider. You can maximize your savings with batteries.

Energy storage uptake through batteries has been increasing in Australia. They are ideal for homes with high energy bills or properties with solar but high night time energy usage. Batteries are the best way to store your excess generated solar power, which is often more economically viable than just availing current feed in tariffs. Even though batteries may take a longer payback period, they often do give maximum energy independence and are another step towards living a sustainable lifestyle.

Solar PV systems are only installed by SAA accredited installers. They are not only registered electricians, but they have also undergone further training to design & install solar PV systems. This ensures all work is on par with industry standards.

Solar PV systems at times are costly and require upfront investments which can become the leading factor why many are not able to avail it. Therefore Z4E has partnered with financing and pay-as-you-go providers to enable anyone to start reaping in the benefits without the hassle of arranging finance. 0% interest finance options with 6 – 60 month terms are also available. We also have green loans, lease and PPA options.

Manufacturer warranties of standard solar panels start from 25 years whereas inverter warranty starts at average 5 years. Panel performance warranty ranges around 30 years. Battery product warranties are at 10 years. We also provide a 5-year retailer’s warranty that covers the operation and performance of the whole PV system, as well as workmanship and products. These retailer’s warranty are provided in addition to consumer guarantees which are required under Australian Consumer Law.

All panels used by Z4E are tier 1, which is just an industry benchmark referring to the manufacturer being given that rating by reputable industry analysts. Nearly all CEC Accredited Panels are tier 1 products.

A Virtual Power Plant (VPP) is a network of solar batteries connected together and managed by software. It helps stabilise the grid by sharing YOUR stored energy when needed. In New South Wales, some VPP programs offer upfront incentives plus ongoing bill credits or payments. This can be combined with federal battery rebates, meaning customers can save thousands per year.

To qualify, your system must use approved products and be installed by an accredited installer. Typically, batteries between 5kWh and 100kWh are eligible (with incentives usually applying to the first 50kWh). The rebate applies whether you already have solar or are installing a new system. Your installer usually applies the rebate for you. This rebate is to decrease every 6 months.

The solar rebate is based on Small-scale Technology Certificates (STCs). The number of STCs depends on your system size, location (postcode), and installation date. Each STC has a market value (around $38–$40 in NSW for 2026). Your installer calculates and applies this rebate upfront, reducing your system cost immediately.

Yes. In NSW, apartment buildings can access the Solar for Apartment Residents program, which covers up to 50% of installation costs (up to $150,000) for shared rooftop systems. The application is made by the owners corporation, and the benefits can be shared among residents, including both owners and tenants.

Yes. Businesses can access solar rebates (STCs) for systems under 100kW, and may also benefit from tax incentives such as instant asset write-offs (if eligible). In many cases, businesses achieve a return on investment within 3–5 years, especially if they use a lot of electricity during the day.

Solar systems are generally low maintenance. Rain often helps keep panels clean, but it’s recommended to have a professional inspection once a year to check the inverter, wiring, and system performance. Monitoring apps also help detect any issues early.

Yes. The best time to charge your EV is during the day (typically between 10am–3pm) when your solar system is generating the most energy. A battery can store excess solar energy for charging later, and VPP participation can further optimise your savings.

Electricity prices can rise or fall over time. Even if prices drop slightly, solar helps you rely less on the grid, protecting you from future increases. By using more of your own energy and exporting excess (or joining a VPP), you can still achieve strong long-term savings.

LGCs are government-backed certificates for large-scale solar systems (typically commercial systems above 100kW). Businesses earn LGCs based on how much energy their system generates, creating an additional revenue stream or financial benefit over time.

Production is the electricity your solar system generates, while consumption is how much energy your home or business uses. Understanding both helps you maximise savings by using more of your own solar energy instead of exporting it to the grid.

Yes. Your system includes an app or online portal where you can track your energy production, consumption, exports, and overall system performance in real time. This helps you understand your savings and identify any issues early.

Our process is simple: a deposit is paid to secure your system and begin approvals (such as grid applications), then a major payment due once we are ready to install your system and then a remaining balance typically due after installation is completed. We also offer flexible finance options, including interest-free plans.

For tile roofs (such as terracotta or concrete), it’s recommended to have spare tiles available. Occasionally, tiles may crack during installation due to their age or condition, and having spares ensures a clean and smooth finish.

Yes. With a battery system, we can set up backup for selected essential circuits (such as lights, fridge, or internet), so they continue running during a power outage. This is an optional add-on based on your needs.

All our systems are designed and installed in accordance with Australian Standards, including AS/NZS 5033 (solar PV arrays), AS/NZS 4777 (inverter requirements), AS/NZS 5139 (battery installation), and AS/NZS 3000 (wiring rules). This ensures safety, compliance, and long-term system reliability.

Yes. After installation, we can guide you on available energy retailers and plans in your area to help maximise your savings. This includes advice on feed-in tariffs, time-of-use plans, and how to get the best value from your solar or solar + battery system.

Battery systems require sufficient clearance for safety and compliance. Typically, around 600mm clearance on the sides and front is required, along with appropriate spacing above and around the unit. Installations are usually done against a non-combustible (fire-resistant) wall where possible. If indoors, it must be in a non habitable room as a minimum and may require smoke alarms and bollards.

Yes, in many cases a solid and level surface such as a concrete footing is required. If a suitable base is not available, we can install one to ensure the battery is securely mounted and compliant with safety standards.

The ideal system size depends on your daily energy usage, roof space, and future needs (like EVs or batteries). We analyse your energy bills and design a system that maximises savings without over- or under-sizing.

Export limits may apply depending on your network (often 5kW per phase in NSW). We design your system to optimise self-consumption and minimise wasted exports.

Yes. In Australia, solar arrays can be oversized up to 133% of inverter capacity. This improves performance in low-light conditions and maximises energy generation throughout the day. For hybrid inverters coupled with batteries, the solar array can be oversized to the maximum available inverter capacity.

Most residential solar systems are installed within 1 day. Larger systems or battery installations may take longer depending on complexity.

It’s recommended but not always required. We will coordinate access and keep you informed throughout the process.

We handle all required approvals, including grid connection applications and compliance documentation.

Most residential systems achieve payback within 3–7 years depending on usage, system size, and electricity rates.

Yes. Solar systems are seen as an upgrade and can increase property value, especially with rising energy costs.

After installation, we provide monitoring setup, performance guidance, and support. We also assist with selecting the best energy retailer plan to maximise your savings.

Yes. Systems can be expanded with additional panels and inverters or upgraded with batteries depending on your future needs.

When installed correctly using compliant products and standards, solar systems are very safe. We follow strict Australian Standards to ensure safety and performance.

Lower-priced systems may use lower-quality components, poor design, or cut corners on installation. We focus on long-term performance, safety, and transparency rather than short-term cost.

Once accepted, we proceed with deposit payment, grid application, system procurement, and scheduling installation. We keep you informed at every stage.

Typically 2–6 weeks from approval to installation, depending on approvals, stock availability, and scheduling.
