Arduino Solar Panel Battery Charger

The following design is for a solar battery charger ran by an arduino nano.

Arduino solar panel battery charger.

A 5v step up voltage booster is also connected to the battery and is used to convert from 3 7v dc to 5v dc. That means 50 latitude roughly the solar cells should nominally provide at least 30 50 times the device power consumption just to provide an approx. To have a 24 24 365 solar power supply i plan to use a solar panel that delivers in winter during daylight enough power to cope with about 2 3 times the total regular consumption of my device. Solar cells are connected to the input of the lithium battery charger tp4056 whose output is connected to the 18560 lithium battery.

A 5v step up voltage booster is also connected to the battery and is used to convert from 3 7v dc to 5v dc. A 5v step up voltage booster is also connected to the battery and is used to convert from 3 7v dc to 5v dc. Solar cells are connected to the input of the lithium battery charger tp4056 whose output is connected to the 18560 lithium battery. 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.

A 5v step up voltage booster is also connected to the battery and is used to convert from 3 7v dc to 5v dc. Solar panel for the arduino board with battery charger. This circuit was based on the awesome tutorial by deba168 solar powered arduino weather station. We like our small solar charger kits for these applications.

Charging voltage is typically around 4 2v. Now we will calculate the size of the solar panel and battery to power my circuit that draws 23 ma. We have more information on sizing your. This arduino board module equipped with a solar panel and a li ion battery can power your arduino project in two ways.

Solar cells are connected to the input of the lithium battery charger tp4056 whose output is connected to the 18560 lithium battery. Calculating solar panel and battery sizes. Using the percentages calculated above this means i will have 6 7 hours of sunlight for charging time on the shortest day of the year 67 of 10 hours 6 7 hours. Furthermore the design has been tested and runs with 90 efficiency under 70ᵒc 158ᵒf.

This circuit was based on the awesome tutorial by deba168 solar powered arduino weather station. Solar panel charges battery battery stores and supplies power runs arduino. Or by connecting the li ion battery to the solar module then the solar module to your arduino board via a pair. Either by connecting your arduino board to the module and the module to its solar panel.

Voltage booster s input ranges from 0 9 to 5 0v. Arduino powered solar battery charger.
