This image shows a solar panel installation designed to power an irrigation system for crops. The panels convert sunlight into electricity, which then drives a water pump. 

This setup provides a sustainable and cost-effective way to irrigate fields, reducing reliance on fossil fuels and grid electricity. It's a clean energy solution for agriculture, particularly in sunny regions where access to traditional power sources may be limited.

How Do I Ensure That I Also Have Water When The Sun Does Not Shine?

I already answered that before. 

Normally, a storage tank is integrated in the design of a solar water pumping system. The storage tank acts as a “battery”. When the sun shines, the tank is filled up, when it is cloudy or dark, water can be used from the tank which is placed at a high point. It is also possible to include a backup generator in a solar water pumping system.
