feed up arduino with a board solar

I have a project which I am making, it is about an irrigation system. I would like to feed up this project with a solar board. this consume 9V and 1 Amp. I have a mini water pump and a relay which turn on or off. humidicity sensor and light sensor in my project. How can I connect feed up my arduino with this board solar. i need a solar charger or battery.

The pump have an external battery. I only want feed up arduino with solar energy and make work this project.


I was looking at web about solar charges but this only output and input 5V and 2 amp


What is the solar cell voltage with the pump connected and running? Which Arduino? How are you controlling the pump with the Arduino? What is the relay's coil voltage and current? Post links to as many of your components as you can.
