At Celtic Solar, we bring reliable, independent power to places the grid can’t reach. Whether it’s a remote farm in the hinterland, an eco-cabin near Noosa, or a coastal getaway, our custom-designed off-grid solar systems deliver uninterrupted power tailored to your lifestyle, location, and daily energy demands.
With 20 years of off-grid expertise and a deep understanding of the Sunshine Coast’s conditions, we design, install, and maintain complete standalone systems that thrive in isolation—giving you true energy independence and long-term peace of mind.
We install off-grid solar systems rated for real Australian conditions. Every system is engineered for safety, longevity, and efficiency, with built-in safeguards to overcome Sunny Coast conditions like extreme heat and moisture—so your off-grid setup works seamlessly year-round.
Off-grid reliability hinges on high-quality energy storage. We essentially become your electricity provider so we want to make sure you have power 24/7, 365 days of the year.
Off-grid living is never one-size-fits-all. Your location, energy usage, building type, and sunlight hours all determine the system that will serve you best. At Celtic Solar, we design off-grid solutions from the ground up—engineering the right combination of panels, batteries, inverters, and backup generation to match your exact requirements. Your site and energy consumption habits determines the best approach, and we take care of the rest.
Whatever your energy goals, our team will design the optimal off-grid system to deliver reliable, long-term performance—even in the most remote locations.

Why Should You Go Solar?
How Solar Powered Energy Works
①
Solar Panels
Well placed solar panels capture sunlight and turn it into a direct current (DC).
②
Solar Inverter
A solar inverter then converts a DC into an alternating current (AC). The AC is what powers your home in real time.
③
Solar Battery
If you choose to install a solar battery, excess energy is stored rather than always pushing it out to the grid.
④
Digital Meter
A device that allows you to monitor energy habits and track your energy use.
⑤
Power Grid
Any excess energy that solar panels generate is pushed out to the grid. This energy is measured and calculated to credit your account. You can also draw energy from the grid when and as you need it.
