Product Overview
The Bioenno Power BSP-28 model 28 Watt Foldable Solar Panel is our original and most popular monocrystalline solar panel featuring both USB and DC output options. Designed for field portability and high performance, this panel allows direct USB charging of devices such as smartphones and tablets and includes a 2.1 mm DC coaxial plug for other power applications. Additionally, the BSP-28 can be chained with another BSP-28 to increase output.
Constructed with high-strength PET polymer laminated solar cells embedded in rugged polyester canvas (PVC fabric), the unit is lightweight, compact, and highly durable. With a folded size comparable to a standard laptop, it’s an excellent choice for off-grid activities, amateur radio operators, surveillance setups, and mobile power needs. This panel was developed in conjunction with the globally adopted Bioenno BPP-160 Powerpack.
- Please note: This solar panel does not include a solar charge controller. Only 5V devices such as phones and tablets may be connected directly to the USB output. For battery charging, always use a matching Solar Charge Controller. Do not connect the panel directly to a battery.
