Folding Solar Panel is Underpowered
In Big Clive’s latest teardown exploration, he ventures into the realm of recently purchased folding solar panels, aiming to uncover the truth behind their advertised specifications versus actual performance. The discrepancy between the product depiction and real-world functionality emerges as the first indicator of potential inaccuracies, with the panel’s output in full sunlight peaking at a mere 2.5 watts, significantly below the advertised 10-watt rating. Such inconsistencies extend across various listings, where sellers tout wattage ratings ranging from 20 to 80 watts, casting doubt on the reliability of claims within online marketplaces.
Undeterred by the lackluster performance, Clive embarks on a meticulous disassembly of the solar panel, eager to unravel its internal architecture. The teardown reveals a minimalist circuit board predominantly housing a buck regulator chip, responsible for supplying a 5V output to the attached USB port. Complemented by ancillary components such as a Schottky diode, an inductor, capacitors, an LED indicator, and a resistor, the circuit board’s simplicity belies the significant gap between advertised and actual performance. This teardown underscores the necessity of exercising caution and skepticism when evaluating the authenticity of claims made by budget electronic products available online.
