BSP-28 Description     Hide

The BSP 28 is a 28 Watt foldable solar panel. So it does not need any charger for it. This foldable solar panel is used for charging up our other complementary product the BPP 120 ( which is a 120 Watt Powerpack) or it can be used in conjunction with our other solar charge controllers (like the SC 122430T and the SC 1220 JU). The BSP 28 has a DC barrel plug that puts out 20-22 VDC (open circuit). The BSP 28 also has a USB output for charging phones and tablet computers (like an iPad).

The Bioenno Power BSP-28 model 28 Watt Foldable Solar Panel is our original and most popular monocrystalline solar panel featuring not only USB output you can directly tap into to charge personal electronic devices such as phones and tablets but also DC output via a 2.1 mm inner diameter Coaxial Plug and the additional ability to be chained with another BSP-28 for increased output.  The solar panel is based on high-strength PET polymer laminated solar panels integrated into a rugged polyester canvas (also known as a PVC fabric), with an extremely lightweight, compact structure that provides excellent wear/weather-resistant durability.  Designed in conjunction with our globally adopted BPP-120 Power Pack, the BSP-28 offers portability and flexibility along with high efficiency and usability with field use in mind. This product has seen use in many sectors ranging from Amateur Radio applications and communications to surveillance and due to its small folded footprint (the size of the standard laptop) is ideal for on-the-go use.
Please note to always use a Solar Panel with a matching Solar Charge Controller when using with battery – attaching a panel directly to a battery is not advised.
