Australian homes come in all shapes and sizes. While some households can achieve impressive savings with a standard rooftop solar system, others require something far more sophisticated. Large homes, acreage properties, swimming pools, sheds, workshops, and growing families all place unique demands on an energy system. That is exactly the challenge Resinc Solar & Batteries faced when designing a solution for homeowners Steve and Shan, featured in episode 7 of Open Homes Australia.
Rather than selling an oversized system or a one-size-fits-all package, Resinc spent two years working alongside the homeowners to understand how they lived, how they used electricity, and how their energy needs would evolve. The result is a carefully engineered solar and battery solution that powers an incredible lifestyle while reducing electricity costs by more than 90%.
Building a forever home deserves a forever energy solution
Steve and Shan’s stunning Central Coast property is much more than a family home. Set on acreage, the modern farmhouse-style residence features extensive entertaining areas, a large swimming pool, multiple refrigerators, a dedicated shed and “man cave”, and plenty of room for family and friends.
Naturally, all those luxuries require electricity.
Before installing solar, the couple’s power bills regularly exceeded $1,200 per month. That equates to more than $14,400 every year simply to keep the property running. While many homeowners would immediately think about installing as many solar panels as possible, Resinc Solar & Batteries took a different approach.
Instead of simply selling more equipment, they focused on designing the right solution.
Every home deserves a custom engineered system
No two households consume electricity in exactly the same way. Some families use most of their power during the day. Others consume the majority after sunset. Some properties have swimming pools, workshops, electric vehicles, or extensive outdoor lighting.
Leigh Storr from Resinc Solar & Batteries explains that every installation begins by understanding how the homeowner actually uses electricity. For Steve and Shan, this meant designing a system that would support their current lifestyle while allowing for future additions to the property.
Over the course of two years, Resinc assessed the home’s evolving requirements as new features, including the pool and spa, were completed. Rather than overcapitalising on battery storage, they carefully balanced solar generation, daytime energy consumption, and overnight battery usage to maximise value.
It is an excellent example of why professional system design matters just as much as choosing quality hardware.
Resinc solar: A solar and battery system built for serious performance
The final installation is impressive by any standard.
Resinc installed:
- 86 solar panels
- Approximately 40kW of rooftop solar
- 44kWh of battery storage
- A premium Fronius inverter and BYD battery solution
- Load sharing designed to power the home, shed, and pool efficiently
With the solar array installed on the property’s large shed, the system supplies power across multiple buildings while intelligently managing electricity demand. Rather than storing every kilowatt-hour generated during the day, the system makes strategic use of solar production.
High-energy appliances, including the swimming pool pumps, operate during daylight hours while solar production is at its peak. The batteries then provide power overnight, reducing the amount of electricity purchased from the grid.
This approach allows the system to achieve excellent performance without unnecessarily increasing battery capacity.
Why load shifting makes such a difference
Battery storage often receives most of the attention, but how electricity is used can be just as important as how much energy is stored. This is where load shifting becomes invaluable.
By scheduling large electrical loads during periods of high solar generation, homeowners can use more of the electricity they produce instead of exporting it to the grid.
In Steve and Shan’s case, Resinc designed the system so that energy-intensive equipment, such as the pool pumps, primarily runs during the day. Battery storage then supports the home’s evening and overnight consumption. This intelligent energy management reduces reliance on the grid while avoiding the additional cost of installing significantly larger battery storage.
It demonstrates that a well-designed system is often more effective than simply installing more hardware.
From $1,200 a month to around $100
The results speak for themselves.
Steve estimates that monthly electricity bills have fallen from approximately $1,200 to around $100.
That represents annual electricity costs dropping from roughly $14,400 to just $1,200.
For many homeowners, savings like these can dramatically improve household finances. Instead of worrying about rising electricity prices, Steve and Shan can focus on enjoying the home they worked so hard to build.
Whether entertaining friends, running the pool, or making full use of the property’s impressive features, the energy system has become an asset that supports their lifestyle rather than limiting it.
Why choosing the right installer matters
Solar panels and batteries are only part of the equation. The expertise behind the design, engineering, and installation can have an enormous impact on system performance.
Resinc Solar & Batteries demonstrated this throughout Steve and Shan’s project by taking the time to understand their needs, monitoring how the property evolved, and designing a system that balanced solar generation, battery storage, and energy consumption.
Rather than encouraging unnecessary spending, they focused on delivering the best long-term outcome for the homeowners. That level of planning is particularly important for larger residential properties where multiple buildings, swimming pools, workshops, and high electrical demand require a more sophisticated approach than a standard suburban installation.
A smarter approach to energy independence
Steve and Shan’s home shows what is possible when premium technology is combined with thoughtful system design. With 40kW of solar, 44kWh of battery storage, intelligent load management, and a solution tailored specifically to the property, they have transformed enormous electricity bills into manageable monthly costs.
It is proof that bigger is not always better. Smarter is.
For homeowners considering solar and battery storage, the lesson is clear. The best system is not necessarily the largest one. It is the one designed around how you live, how you use energy, and how your needs may change in the future.
As Resinc Solar & Batteries demonstrates, a custom engineered solution can deliver comfort, energy independence, and substantial long-term savings for years to come.
