Choosing the Right Solar System
Choosing the right solar system starts with understanding your home and lifestyle. Every household is different, from roof size and sunlight hours to how and when you use power. We will guide you through the options and tailor a system that fits your needs today, while leaving room for future flexibility.

How much power does it produce?
SigenStor batteries come in modular sizes from 5 kWh up to 48 kWh.
A smaller household might start with around 10 kWh, enough to cover evening use after the sun goes down. A family home could step up to 15–20 kWh, giving plenty of storage for appliances, hot water, and lights. For larger households or anyone adding EV charging, systems can expand right through to 30 kWh+, providing true energy independence.
How much could I save?
With a SigenStor system paired to a 5 kW solar array and a 10 kWh battery, a typical family home in the Southern Lakes can save around $1,800–$2,000 every year on power bills. That’s based on covering most evening and night-time usage from stored solar instead of buying from the grid at ~$0.35/kWh. Over the 25-year life of your panels, that adds up to $45,000+ in savings, while also giving you backup power during outages and the flexibility to add EV charging in future.
Every household is different, so this is an example only, actual savings depend on your energy use, rates and lifestyle.
Solar only system
A solar-only system with a hybrid inverter is a smart way to future-proof your home.
The panels on your roof generate clean power for your household during the day, lowering your grid use and cutting your power bills straight away. By using a hybrid inverter instead of a standard grid-tie model, your system is ready to connect a battery later without extra upgrades. That means you can start saving today and keep the flexibility to add storage or EV charging when the time is right.

How much could I save?
With a 5 kW solar-only system, a typical family home in the Southern Lakes can save around $1,600–$1,750 every year on power bills. That’s based on using most of the solar power during the day (appliances, hot water, lighting) and earning credits for surplus power exported to the grid at around ~$0.12/kWh. Over the 25-year life of your panels, that adds up to $40,000+ in savings, all while reducing your reliance on the grid and protecting yourself against rising power costs.
Every household is different, so this is an example only, actual savings depend on your energy use, rates and lifestyle.
