Solar BAR Tech Specs 

The Solar BAR is designed for long duration continuous monitoring. It has a built-in solar panel and charge controller with no external cables. It is capable of recording continuously (or scheduled) for years with only minimal service visits to change the memory cards.



Case and Mounting

With the solar panel mounted firmly on top, there are no cables or other connections to worry about. Simply connect the microphone and close the lid. A lockable case made from tough UV resistant plastic. The Solar BAR has a unique mounting plate with a variable pivot allowing the user to adjust the mounting angle to capture the most light. Comes with spanner and bolts to mount to star picket.


Recording Capabilities

4 x SD card slots. Supports 16-bit WAV and FLAC (lossless compression) recording at sample rates from 8kHz to 96kHz.


GPS Features

The built-in GPS automatically time-syncs and GEO-stamps your recordings. Set to continuously record or schedule your own listening pattern.


Schedule Recordings with Ease


All Frontier Labs acoustic recorders come with easy-to-use scheduler software. Program any sampling schedules with ease, including sunrise/sunset based recordings, different recordings on different days and waking up at a future date.



Our highly sensitive, low noise omnidirectional microphones have a 20dB class A pre-amp and cable driver plus an internal memory chip. These features allow the recorder to automatically log the microphones’ serial number and manufacture date for every recording you make, automatically tracking the age of your microphones.

The Solar BAR ships with one microphone included, but as all microphones exposed to the elements eventually degrade, we recommend purchasing multiple microphones in order to maintain high-quality recordings.

Power & Batteries


The Solar BAR has a built-in 10W monocrystalline solar panel that continually recharges the 12V 7.2Ah onboard battery, allowing for continuous recording. Even without any sunlight, the recorder can operate for approximately 1000 hrs (41 days) of continuous recording. The built-in solar controller and battery charger is optimised for super-quiet performance to ensure optimal acoustic recording.


  • Height: 11.5 cm Width: 30.5 cm, Depth: 25cm, Weight: 4kg (including battery)

  • 4 SD card slots up to 1TB each (4TB of storage).

  • FLAC lossless compression effectively doubles your storage capacity, meaning you can record up to 8TB of equivalent wav files.

  • Supports multiple sample rates: 8kHz, 16kHz, 22.05kHz, 32kHz, 44.1kHz, 48kHz, 96kHz (with corresponding anti-aliasing filters).

  • Highly sensitive, ultra-low noise omnidirectional microphone includes a 20dB class A pre-amp and output driver for cables.

  • Adjustable gain up to 60dB.

  • Built-in GPS time-sync and location stamping

What does Australia sound like?

The Solar BAR was initially created to fulfil the ambitious dreams of those working on the Australian Acoustic Observatory project. This joint initiative between five Australian universities and several leading conservation organisations aims to continually record 400 ecosystems across the continent for 5 years - that's more than 2000 years of acoustic data!
