9V 3W Monocrystalline Mini Solar Panel Photovoltaic Panel
A part of the review has been auto-translated.
works with fine with direct sunlight delivery a little less 3w because is winter with a dc-dc converter i charge my kindle(baterry have 1000mah) up to 75% in around 4 hours. Can easy run Arduino Mega or esp32.
In my region there is not always a lot of sunshine, so I bought a panel with enough voltage and power reserve to always have enough energy. I will test how it performs in longer time perspective, so far the results seem very good for my purpose. Recommended.
Works wery well. I have acces to a Wötch Solar simulation chamber, so i did a exposure test, at 860W/m2 (Mid day in Denmark). MP(Watt) was 1.61W, quite good (ideal should be 1.85w/m2) Very satisfied with the output, the module itself bend a little, i heated it in the sun before gluing all 3 panels to my Boom Box. I can recomend a LT3652 based MPPT regulator for use with this panel (up to 3 panels and 14.1V battery MAX) if a LT3652HV is used, 4 panels and 18.0V battery MAX can be used.
Looks solid build. at full sunlight it really gives 9v and 3watt. I use it for an usb mobile charger and that works well.
The product is very good quality. Working according to the description and great value for the money.The delivery time was not very long.
I recived it in agood status. thanks alot
