Arduino Rechargeable Battery Solar Panel

It is perfect for anyone who is interested in doing arduino projects that do not require a computer or any power supply.

Arduino rechargeable battery solar panel.

What you will need. Support forums and product manual can be found on the nightshade electronics website. Calculating solar panel and battery sizes. Calculating solar panel and battery sizes.

Voltage booster s input ranges from 0 9 to 5 0v. 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. Solar cells are connected to the input of the lithium battery charger tp4056 whose output is connected to the 18560 lithium battery. 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. 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. Charging voltage is typically around 4 2v.

The energyshield can be assembled as an arduino shield or used as a generic breakout board with the breakout header. 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 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. 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.

You can take this to the most remote places for any project. 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. Now we will calculate the size of the solar panel and battery to power my circuit that draws 23 ma. 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.

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