Arduino Rechargeable Battery Solar Panel

Selecting the right arduino for your project.

Arduino rechargeable battery solar panel.

You can use one of phone solar battery chargers from ebay. Given these we must choose a solar panel capable of at least 5 7 v 164 mah and a lithium battery rated at 1044 mah. Arduino pro mini or arduino nano. Sleep saves battery however the sensors and power regulators 7805 will still consume battery in idle mode draining the battery.

1 x li ion battery charger module tp4056 5v mini usb 1a. 3 7v 18650 lithium ion battery 2000 mah or more 6v dc 500 ma solar panel breadboard. 1 x boost step up power supply module dc 0 9v 5v to dc 5v. It can handle a standard lead acid 12v battery like for a scooter or a car.

Solar panel rated at 10w have maximum power of 10w and thats rating for direct sun light. Li ion battery charging cycle. Battery chemical composition dc voltage v solar panel mounting method. The lithium ion battery is rated at 2000 mah.

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. This project can also solve the efficiency issue of arduino when in sleep. Mcp1700 3302e 3 3v voltage regulator. 8000mah weatherproof power bank with solar recharging.

It can take up to 20v on the input site of the charger. Lets take 100 mah for charging the battery total current required 100 100 200mah from the above calculation it is clear that we need a solar panel of 4v and 200mah. Solar cables connectors. Furthermore the design has been tested and runs with 90 efficiency under 70ᵒc 158ᵒf.

The solar panel battery only needs to power an arduino mini a dht22 sensor and a low power 433mhz rf module. So technically thats bad idea. They will look good in your art. Our inexpensive solar charger project will be an excellent solution for a situation like this to power an arduino board.

Light weight and solar rechargeable led light package. If you are really want to use solar power. So we re talking about 100 maybe 200ma. This will be the outdoor wireless sensor for a weather station.

However you can try to extend time on battery with few small solar panels. 1 x solar panel module 6v 1w. 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 following design is for a solar battery charger ran by an arduino nano.

Jumper wires actual values will depend on your project s power requirements.
