Brunton Solaris 52 is a workhorse in the field. CIGS (Copper Indium Gallium diSelenide ( solar glossary )) are the most efficient thin film solar panel technology available. By maximizing performance while optimizing portability, it makes the Brunton Solaris 52 the most compact high output model and a great choice for off the grid power.
On expeditions, hiking, and camping two things are important to me, portable power and the portability of the power or weight of transporting the power Vs benefit. Brunton Solaris 26 does a nice job of charging rechargeable batteries, but the Brunton Solaris 52 is serious solar electricity. I use it for extended back-country weekends or camping when I want to work on my laptop in the field. The Brunton Solaris 52 can power your devices like most laptops, and provide a trickle charge to other applications. It is voltage regulated once devices are connected, so the power is paired down to 12 volts for your devices.
Tech Stuff – 12V output for operating laptops, video and digital cameras, and DVD players. Overall dimensions open: 50″ x 31.5″. Overall dimensions closed: 11″ x 9.5″ x 2″. Weight: 3 lb 8 oz. Built-in blocking diode prevents reverse battery discharge. Max Output: 52 watts.
The Solaris 52 is about the size of a regular textbook. The folding cover has a Velcro closed pocket for the three types of cables provided with the device, and even with those cables in the front pocket the device presents a minimal profile in your backpack or carrying case. The panels are applied to a thin type of ripstop waterproof canvas. It’s a sturdy material which retains the folding pattern of the panels so set up an tear down are a snap. I have used the Brunton Solaris on cloudy days and still found it performed well. Not really much of a surprise since solar panels in San Francisco will produce up to 70% of their power rating in the frequent fog.
What Brunton has designed and manufactured here is an efficient, lightweight and extremely capable portable electrical power plant that will require little to no maintenance from the user. All the device needs is a little cleaning with a cloth every now and then to remove dirt or debris.
Brunton Solaris 52 (as well as the Solaris 26) has a built-in reversing diode and charge regulator that prevents the solar array from discharging your battery at night.The panels are waterproof but do not keep the solar panels submerged underwater. The Brunton Solaris portable solar are designed for portable outdoor use over extended peiods of time. If you have an RV or car battery that you want to trickle charge, you should use the Brunton SolarController to monitor charge level and prevent over charging which can ruin you battery. When you start your engine, you do not have to disconnect the Brunton Solaris from your battery.
The Brunton Solaris 52 will work to charge most laptops. The included 12 volt vehicle output cable can be connected to your laptop’s 12 volt vehicle plugin cable. However, the Plugin cable is specific to your laptop.

Link up to three units together for more output. Charge vehicle batteries w/ battery clamp cable. Works in all types of weather, even in low light cloudy conditions. Built-in blocking diode prevents reverse battery discharge. BUT use a charge controller. Charge times are estimates only, and depend on several factors including device, weather, location and angle of exposure.
