Our Battery Installation Services
At RK Solar, we understand that every home and energy need is unique. That’s why we offer a comprehensive range of battery installation services tailored to meet your specific requirements. Whether you are starting fresh, upgrading your existing solar system, or simply adding storage, our expert team will guide you through every step to maximise your energy savings and reliability.
1.Battery Add-On to Existing Solar
If you already have solar panels installed, adding a battery is a smart way to capture and store the excess energy your system generates during the day. This stored energy can be used in the evenings or during peak demand periods when electricity prices are highest, reducing your reliance on the grid and lowering your energy bills.
– Store surplus solar energy for use when the sun isn’t shining.
– Avoid expensive electricity rates in the evenings and early mornings.
– Keep essential appliances running during power outages (depending on system size and setup).
– We ensure your battery works perfectly with your existing inverter and solar setup.
– Take advantage of government battery rebate program even if your solar system is older.
2.New Solar + Battery System
For homeowners who are new to solar or looking to upgrade their entire energy system, our team designs and installs fully integrated solar + battery systems that work seamlessly from day one, delivering maximum energy efficiency and cost savings.
– Tailored solar panel array and battery size based on your energy usage, roof space, and budget.
– We use industry-leading inverters and batteries (Tesla Powerwall, Enphase, Sigenergy, and more) for optimal performance.
– We help you take advantage of available federal solar and battery incentives to reduce upfront costs.
– Designed with flexibility to add more batteries or smart energy management tools later.

What Our Customers Are Saying
“We purchased an 8KW solar system comprising of Enphase microinverters and Sigenergy batteries recently. The process from sales till installation has been pretty smooth with timely correspondence and response. The installation team has done a neat and tidy job. After the installation, the team explained the operation of the system which was very easy to understand. I also received a call from the service team to explain about the apps which have built my trust. I would be happy to recommend RK solar to anyone.”
— Waleed Arshad
“We got 10.5kW Q.Cells Solar panels + 8.2kW Fronius Primo installed 4 years ago and were very happy with the installation. RKSolar was the choice from the 3 leads provided by Solarquotes.
Recently got a 32kWh Sigenergy battery + 10kW SP Inverter installed thanks to the Federal Rebates and naturally we choose RK Solar again. The installation was meticulous and the staff took time to explain how the system works, we even tested the backup function of the battery and set up a time based schedule. Absolutely will recommend these guys and they have been around for 15 years.”
