Generate your own electricity and reduce daytime grid usage.
Best suited to households that use a reasonable amount of electricity while the solar system is generating.
- Lower upfront investment
- Reduce daytime grid electricity purchases
- Run air conditioning and appliances from solar
- Use solar for electric hot water and pool equipment
- Export unused solar to the grid
- Battery can potentially be added later
Solar + Battery
Generate, store and use more of your own energy day and night.
A properly sized battery can store excess daytime solar for use during the evening, overnight or during higher-cost electricity periods.
- Store excess daytime solar
- Reduce evening grid electricity purchases
- Backup power options during blackouts
- Better use of larger solar systems
- Smart energy management
- Excellent option for homes with higher evening usage
- EV charging integration available
Already have solar?
You may not need to replace it. Makn Energy can assess your existing system and determine whether adding battery storage, expanding your solar or upgrading the complete system provides better value.
How Much Can Solar & Battery Save?
Your savings depend on your electricity consumption, when you use electricity, solar system size, battery capacity, electricity tariff and feed-in tariff.
The biggest savings generally come from using your own solar energy instead of purchasing electricity from the grid. A battery can increase the amount of solar energy your household uses by storing excess generation for later.
Send us a recent electricity bill and we'll recommend a solar or solar + battery system based on your actual energy usage.
FIND MY IDEAL SYSTEMActual savings vary between households and depend on individual usage patterns, tariffs and system design.
Solar & Battery Rebates in Adelaide
Eligible Adelaide homeowners may be able to reduce the upfront cost of both solar panels and home battery storage through Australian Government incentives.
Federal Solar STC Incentive
Eligible residential solar systems can receive Small-scale Technology Certificates (STCs), which reduce the upfront cost of installing solar.
At Makn Energy, the applicable STC value can be applied directly to your solar quote, so you don't normally need to claim the incentive separately.
The amount depends on factors including the system size, installation date, location and current STC value.
Cheaper Home Batteries Program
Eligible home batteries connected to new or existing solar may receive an upfront discount through the Australian Government's Cheaper Home Batteries Program.
The government describes the program as providing a discount of around 30% for a range of eligible battery systems, although the actual discount depends on battery usable capacity, installation date and STC value.
Eligible battery systems can range from 5kWh to 100kWh nominal capacity, with STC support applying to the first 50kWh of usable battery capacity.
Solar + Battery Can Receive Both Incentives
When eligible solar and battery storage are installed together, the solar system may qualify for solar STCs while the battery may separately qualify for battery STCs under the Cheaper Home Batteries Program.
Makn Energy Can Handle the Rebate Process
We can calculate the applicable STC incentives and show them clearly in your solar or battery proposal, subject to eligibility.
Government incentives, STC values and eligibility requirements can change. Actual discounts depend on the system, installation date and applicable program requirements.

Your Complete Guide to Solar Panels in Adelaide
Going solar is one of the best investments a South Australian homeowner can make. With some of the highest solar irradiance in the world and generous government incentives, SA households can dramatically reduce their electricity bills and carbon footprint. This guide walks you through everything — from how the technology works to what size system you need and how quickly it pays for itself.
How a Home Solar System Works – Panels, Inverters & Batteries
A solar system is more than just panels on a roof. Understanding the key components helps you make a better buying decision.
25 yrs
Performance warranty
Solar Panels
Solar panels convert sunlight into DC electricity. Modern panels use monocrystalline silicon cells and typically achieve 20–23% efficiency. The number of panels you need depends on your system size and the wattage of the panels selected.
We install panels from reputable manufacturers with genuine 25-year performance warranties. Panel quality matters — cheaper panels degrade faster and their warranties are harder to claim.
10 yrs
Inverter warranty
Solar Inverter
The inverter converts DC electricity from your panels into AC electricity your home can use. It's the brain of your solar system — monitoring performance, managing grid connection and protecting against faults.
There are three main types: string inverters, hybrid inverters that can also manage a battery, and microinverters mounted behind each panel. We'll recommend the right type for your roof and future plans.
10 yrs
Battery warranty
Battery Storage
A home battery stores excess solar energy generated during the day so you can use it in the evening instead of buying from the grid. It also enables blackout protection on compatible systems.
Battery storage is optional but increasingly popular in SA, where evening electricity rates are high and feed-in tariffs are low. The Federal Cheaper Home Batteries Program currently discounts the installed cost significantly.
25+ yrs
Structural lifespan
Racking & Mounting
Racking is the aluminium frame system that holds your panels to the roof. It needs to be engineered for your roof type, pitch and local wind loads. Poor racking is one of the most common causes of long-term solar problems.
We use quality racking systems with stainless steel fixings and install to Australian Standards. Every penetration is properly flashed and sealed.
Real-time
System visibility
Monitoring
Modern solar systems include monitoring via a smartphone app. You can see how much solar you're generating, how much your home is consuming, what you're exporting to the grid and — if you have a battery — its state of charge.
Good monitoring lets you spot problems early and optimise how you use your solar. We set up monitoring as part of every installation.
Rebates and incentives available right now
We'll show every rebate as a line item on your quote so you can see exactly what you pay.
Small-scale Technology Certificates (STCs)
The federal solar rebate, applied as a point-of-sale discount. We handle the paperwork and the discount shows on your quote.
Federal Cheaper Home Batteries Program
A significant discount on the installed cost of a home battery, available on new solar-and-battery systems and on batteries added to existing solar. The discount rate steps down over time, so sizing your solar for a battery now keeps that option open.
Feed-in Tariff
Export excess solar to the grid and receive a credit on your electricity bill. SA feed-in rates vary by retailer. A battery can help you use more of your own solar instead of exporting at low rates.
SA Retailer Energy Productivity Scheme (REPS)
May apply to certain upgrades such as hot water. We'll check eligibility as part of your quote.
How Long Does a Solar System Last?
| Component | Expected Lifespan | Notes |
|---|---|---|
| Solar panels | 25–30 years | Performance warranty typically 25 years. Physical lifespan often longer. |
| Inverter | 10–15 years | Usually the first component to need replacement. 10-year warranties standard. |
| Racking & mounting | 25+ years | Aluminium and stainless steel construction. Minimal maintenance required. |
| DC wiring & connectors | 25+ years | UV-rated cables. Inspect periodically for damage or degradation. |
| Battery (if installed) | 10–15 years | Typically 10-year manufacturer warranty. Capacity degrades gradually over time. |
Maintenance and System Lifespan
Solar systems require minimal maintenance. An annual inspection and occasional panel clean is usually sufficient. Because Makn Energy's own licensed electricians install every system, you call us directly if anything needs attention — not a call centre.
Quality panels carry a 25-year performance warranty, inverters typically 10 years, and our workmanship is guaranteed for 10 years.
Upgrading an Existing Solar System
Already have solar? You may be able to add panels, upgrade your inverter, add a battery or improve monitoring without replacing the whole system.
Add a Battery
Store excess daytime solar for evening use. Most existing systems can have a battery added. We'll assess your inverter and system size first — and tell you honestly if adding panels makes more sense.
Add More Panels
If your existing system is undersized for your current usage or a planned battery, adding panels is often cost-effective — especially if your inverter has spare capacity.
Replace an Ageing Inverter
Inverters typically last 10–15 years. Replacing an older unit with a modern hybrid inverter can improve performance and open up battery storage options.
Improve Monitoring
Modern monitoring systems give you real-time visibility of solar generation, consumption and battery state. Some older systems can be retrofitted.
