Flexible Solar Cells E60 C60 5x5 3.6W Monocrystalline Cells for DIY Panels (40, +1 Busbar Per Cell)

The Sunpower Flexible Solar Cells E60 C60 are advertised as flexible and high-performance solar cells for DIY solar panels. However, customer experience and reception of this product paint a mixed picture. One customer mentions that these cells are not as flexible as advertised and are actually quite fragile. This may not be suitable for those who are looking to mount the cells on a car or any other surface that may be subject to movement or stress. It is suggested that purchasing a pre-built panel may be a better option in these cases. Another customer raises a concern about potential leakage at night if the cells are connected straight to a 12V battery. It is recommended to use a charge controller to prevent any voltage drops or battery current flowing back into the cells. Using a diode is also suggested as a cheaper alternative to a charge controller. In terms of specifications, each panel contains 20 cells, with each cell measuring 5 x 5 inches. The cells are claimed to have an output of around 6 amps based on their 3.6 watts and 0.6 volts rating. Feedback regarding the quality of the cells varies. Some customers reported receiving cells with blemishes and scratches, although these did not affect the performance in some cases, and some even performed better. It is noted that measuring the current of the cells directly from the pads using a conventional multimeter can be tricky and may require correctly soldered wire leads.
