Arduino Rechargeable Battery 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.

Arduino rechargeable battery solar panel.

Support forums and product manual can be found on the nightshade electronics website. Now we will calculate the size of the solar panel and battery to power my circuit that draws 23 ma. You can take this to the most remote places for any project. Calculating solar panel and battery sizes.

Voltage booster s input ranges from 0 9 to 5 0v. 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 energyshield can be assembled as an arduino shield or used as a generic breakout board with the breakout header. Charging voltage is typically around 4 2v.

Calculating solar panel and battery sizes. Charger is fed via solar panel and or usb supply battery is continuously supervised and charged on demand arduino is connected to the output side of the charger this works because the load that the arduino presents is relatively small compared to what the charger can feed and what the battery can take. Now we will calculate the size of the solar panel and battery to power my circuit that draws 23 ma. 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.

A 5v step up voltage booster is also connected to the battery and is used to convert from 3 7v dc to 5v dc. 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. The battery can be recharged with a 10w 6 18v solar panel at maximum power point mpp control a 5 24v dc adapter center or usb.

The energyshield 2 pro regulates its usage of the solar panel in order to maintain maximum power generation mppt power sleeping in order to prolong battery life the energyshield 2 pro can turn off its power output and sleep for a programmable amount of time after which the power turns on and your arduino executes it program again. 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. 9v rechargeable battery solar cells about 11v 1n4001 diode 100uf 10v capacitor arduino board 9v battery connector power connector to connect to the arduino board. Solar cells are connected to the input of the lithium battery charger tp4056 whose output is connected to the 18560 lithium battery.

This circuit was based on the awesome tutorial by deba168 solar powered arduino weather station.
