Customer Story
From High Electricity Bills to a Solar & Battery System That Works
John already had solar, but his existing system wasn't meeting his household's energy needs. With the pool and air conditioning outside the original solar setup, electricity costs were still significant.
After talking through his options with Decarby, John upgraded his solar, added battery storage and moved to a three-phase setup designed around how his home actually uses energy.
What mattered to John wasn't simply finding the cheapest system. He wanted value for money, clear advice and someone who could explain his options in plain English.
“The savings for us are 80%, easy!”
— John
FAQ
Frequently asked questions
Clear answers to common questions about solar installation, battery storage, and electrification.
What energy services does Decarby provide?
Decarby provides residential and commercial energy solutions including solar panel installation, battery storage, EV charging, heat pump hot water, air conditioning, induction cooking and broader home electrification. We can help from initial consultation and system design through to installation.
Does Decarby install solar and battery systems in Canberra?
Yes. Decarby provides solar and battery solutions for homes and businesses across Canberra and surrounding areas. Each system is designed around the property, energy requirements and future energy plans rather than using a one-size-fits-all approach.
Does Decarby work with both residential and commercial properties?
Yes. Decarby provides energy solutions for both homeowners and businesses. Residential projects can include solar, batteries, EV charging and home electrification, while commercial projects can include solar, battery systems, charging infrastructure and broader electrification solutions.
Can Decarby help me choose the right solar and battery system?
Yes. Decarby's approach starts with understanding your property, electricity use, budget and future plans. The goal is to recommend a system based on what makes practical and technical sense for you rather than simply selling a predetermined package.
Can Decarby help with government solar and battery rebates?
Decarby can help you understand the rebates and incentives that may apply to your project and explain how they affect your options. Eligibility and available support can vary by technology, property and government program, so applicable incentives should be confirmed for your individual project.
What areas does Decarby service?
Decarby services Canberra and surrounding areas, including Queanbeyan, Jerrabomberra, Googong, Yass, Bungendore and Murrumbateman, as well as other communities around the ACT region.
Can Decarby help electrify my whole home?
Yes. Home electrification can involve moving more of your household energy use to efficient electric technologies such as solar, battery storage, EV charging, heat pump hot water, electric heating and cooling, and induction cooking. Decarby can help you consider these technologies as part of a broader energy plan.
Do I need to install solar and a battery at the same time?
Not necessarily. Solar and battery storage can be considered together or at different stages depending on your existing system, electricity use, budget and future plans. Decarby can assess your situation and explain the options that make sense for your property.
How does Decarby's consultation process work?
The process begins with understanding your property, current energy use and what you want to achieve. Decarby can then assess suitable technologies and system options, explain the recommendations clearly and develop a solution before progressing to installation.
Can I get an estimate of how much solar could save me?
Yes. Decarby's Solar Savings Calculator provides an indicative estimate based on information such as your electricity bill, billing period and whether you're considering solar only or solar with battery storage. A personalised assessment can then consider the details of your property and energy use.
