Deren and his team really helped me decide what I needed and guided me all the way through from planning to installation to maintenance. Deren made sure the design Fox Cloud 8 KW battery storage with a 4KW 8 panel East West facing provided the most efficient orientation and what I needed to be more or less self sufficient most of the year. The system was installed in late 2022 so is two and half years old and all has been working exceptionally well. JD Allen helped me when I had any issues and can do monitoring checks on your data remotely.
JD Allen installed solar panels and a battery for me in 2025. Our setup was complicated due to the age of our house and the setup of our main fuse-box, but they handled the job neatly and to schedule. The opportunity to have someone come out and inspect our setup before quoting helped immensely. I am happy to recommend them.
Highly recommended, very professional and honest, the engineers are overly knowledgable, I had zero complaints with the workmen. I would go back to JD Allen Engineering for any future works. Thank you for the solar and battery installation. Regards, Stewart.
