The battery is a 12v 1 3 amphour battery the length of time the battery last very much depends on what you are doing with.
Raspberry pi solar panel battery.
The weather protection proved to be great even during the winter months and my raspberry pi never had issues with the temperature ranges either to get as much energy as possible the solar panel and the 12 v battery were positioned up high on a wooden frame with the security camera device attached too.
This board can also power the larger raspberry pi 3b whereas many kits can only charge the pi zero.
According to jeff greerling the raspberry pi zero w uses around 0 4w a super low consumption.
This is my solar battery monitoring system based on raspberry pi.
The power bank choice was essential too it had to fulfil the following criteria.

One of the main hazards associated with running a raspberry pi from a battery is the potential to damage the pi if it is abruptly turned off.
Solar panel paramets and utility voltage parameters are accessible via web interface.
However make sure that the output voltage is 4 75v to 5 25v as shown in the led display.
I m setting up an off grid solar solution and the mppt controller i purchased only supports modbus via serial.
Makerfocus raspberry pi 3 battery pack raspi ups hat board usb battery pack raspberry pi expansion board power supply with 2600mah lithium battery for raspberry 3b 3b 2b.
Raspberry pi solar panel module.
Has to have at least 10 000mah battery.
Has to have a solar panel for topping up the charge.
Some boards such as the one i m using will also power the pi directly from the solar panel when the battery is full.
But here is quick calculation if the raspberry pi uses 3 watts a hour then a 12v battery at 1 3 amp hours gives 15 6 watt hours so 15 6 divide by 3 gives you 5 3 hours.
This board will convert the energy from the solar panel into stored battery power.

For this guide i ll be using the pijuice solar kit since it includes both a solar panel and a power management board.
If you are using a different version of raspberry pi you can still power it with a 9v solar panel and lm2596 buck converter.
The raspberry pi choice had to be a zero w.
Recommended power management hat.
It monitors six solar panels connected to battery charging controller.
Communication with battery controller is made through raspberry pi serial port at 2400 baud.
