How portable solar panels work?

Unlike solar panels you might place on your roof, which are set in a fixed rigid frame and sealed under glass, typical portable solar panels are usually wrapped in a protective sleeve made of mesh fabric or plastic. Small, cheap (under $50) panels will produce 5 to 50 watts of power, while larger ones can produce 300 watts or more—the same as regular rooftop solar panels. Smaller panels are typically monolithic silicon solar cells, while larger panels may have two or three panels in a foldable version.

These panels feature a simple jack or set of jacks that output power to a variety of devices. You may find a DC output jack and a USB port, allowing users to charge their phone or laptop directly. Most often, portable solar panels are paired with portable lithium-ion batteries so their energy can be used in any conditions. (You cannot charge the battery while in use, however.) Batteries can have a wider range of output devices, from a standard household 120-volt AC outlet to a DC output jack.

While the output of some larger panels can be equivalent to that of regular rooftop solar panels, portable panels are not meant to replace rooftop solar panels. By design, they lack the structural integrity and voltage regulation of a properly installed rooftop solar system.

Installing portable solar panels, on the other hand, only takes minutes, requires no permits or inspections, and doesn’t have to worry about damaging your roof. All solar photovoltaic (PV) panels are made from crystalline silicon wafers that absorb sunlight. Light (photons) from the sun releases electrons from the silicon material, creating an electric current along the electrical conductors in the cell (hence the name "photovoltaic"). Electrical current flows from the battery in one direction (direct current or direct current), directly into a device that accepts DC power (such as a battery), or indirectly through an inverter to produce alternating current (AC) for most home uses.
