Arduino Powered Solar Panel

Arduino powered solar panel.

This uses the energy from some solar cells to charge the batteries and boosts the voltage from it to the 5v used by the arduino uno. The following design is for a solar battery charger ran by an arduino nano. It can handle a standard lead acid 12v battery like for a scooter or a car. Uxcell 5pcs 5v 60ma.

I eventually found a cheap 5 volt one and measures its output to be almost exactly 5 volt and also snagged a battery from a defunct ps 4 controller. You need to allow for a lot of energy inefficiency in the battery i suggest at least 50. Then taking account of local sunshine patterns you need to figure out what size of solar panel is needed to deliver the required energy. The setup worked quite well.

But found those too low to do anything. Before you can specify a solar panel you need to know how many watt hours per day your arduino will use. A time switching battery powered solar charged circuit used to power an arduino uno and some peripherals. Now that we are certain that the solar panel generates power we can connect it to the arduino.

This circuit was based on the awesome tutorial by deba168 solar powered arduino weather station. Battery capacity is 1300mah c 10 130mah the solar panel has to provide current 100mah for arduino along with a current not more than 130mah. The sensor module along with arduino taking 100mah current. Battery voltage 1 2 x 2 2 4v so required voltage for solar panel 2 4 x 1 5 3 6v by taking some margin we can choose a 4v solar panel for it.

Solar panel charges battery battery stores and supplies power runs arduino we like our small solar charger kits for these applications.

Solar charged battery powered arduino uno project in progress by igor fonseca albuquerque microcontroller based solar pv system s charge controller inverter powerbank led lamp with menu based navigation system on lcd display. Supplying the necessary power for the arduino and how to use a 3 pin voltage regulator because the amount of light the solar panel gets from the sun determines its voltage output we will need to use a 3 pin voltage regulator in order to supply a steady 3 3v to the arduino. We will also touch on power management and charge controllers. Get it as soon as fri sep 11.

Components needed for this project. I2c fuel gauge solar charging power sleep rtc shield for arduino uno r3 mega. Furthermore the design has been tested and runs with 90 efficiency under 70ᵒc 158ᵒf. The v15 v50 v75 and v88 batteries charge efficiently from solar and have an always on mode which keeps them on whether or not a device is drawing any power.

Dfrobot 900ma mppt solar panel controller solar power manager module for 5v solar panel support solar and usb charging. I played a little with my mkr early on to simply try power it from solar using some panels i had reclaimed from solar lamps etc. Solar power can often be a useful solution for powering such devices.
