3V, 0.8A Solar Panel, 3V Supercapacitor EnclosureThis can be used to power microcontrollers and an array of sensors near or below a 3V operating range intermittently.Design is free and open source.2x 3V (~3.5V open circuit), 400mA solar panels soldered in parallel to give a current output of 0.8 Amps (2 x 400 mA).Fixture serves a dual purpose of soldering and wiring solar panels together and keeping them in place.This time the fixture was printed using HP MJF PA12 Nylon because the PETG used last time deformed/melted from excessive heat in the enclosure.They claim a heat deflection temperature of 170 °C.https://h20195.www2.hp.com/v2/GetDocument.aspx?docname=4AA7-7084ENWThe solar panels will charge a 3V supercapacitor.Use the ideal diode(s) below to minimize forward voltage drop and reverse current leakage (minimizing reverse current leakage is important so supercapacitor does not lose charge and send current back to panels when they are shaded or during night time).I used the calculator below to increase the length of wire from the solar panel to the capacitor to create enough of a voltage drop to prevent overcharging the super capacitor.https://www.inchcalculator.com/voltage-drop-calculator/Link to 3V, 400 mA and solar panels and suppliers:3V, 400 mA, Polycrystalline Solar Panelhttps://www.amazon.com/dp/B0B7RLWDT2Link to 3V, 450F supercapacitor I will be using that will get solar charged:https://www.digikey.com/en/products/detail/tecate-group/TPLH-3R0-450SS35X71/9930287Caution serious injury or death may occur if you don't know how to use the supercapacitor!i.e. it short circuits.Use this ideal diode to prevent reverse current leakage from the supercapacitor to the solar panels when they get shaded or it gets dark:https://www.analog.com/en/products/max40203.htmlUltra-Tiny Micropower, 1A Ideal Diode with Ultra-Low Voltage DropCurrent Switch/Ideal Diode Saves Space and Offers 10x Lower Voltage Drop Than Schottkys.Digikey Supplier:https://www.digikey.com/en/products/detail/analog-devices-inc-maxim-integrated/MAX40203ANS-T/11484044Alternate diode with larger amperage rating and higher voltage drop:SR560 Schottky Barrier Rectifier Diode, 5A, 60V, DO-201ADhttps://www.amazon.com/dp/B079KCWPWQ
