Solar Irrigation

The answer could be a solar pump. This type of water pumping is about as simple as it can get. A solar panel coupled directly to a DC water pump, without any batteries or inverters in between. When it’s sunny, water is pumped. These are commonly used in agricultural applications such as irrigation or livestock. Farmers around the world are switching to solar stock watering and drip irrigation due to its simplicity.

This entry level water pumping package includes everything required for a reliable and low maintenance water supply purposes. This system will provide varying quantities of water according to your site conditions, the principal factor being the total head - or vertical distance the water must be pushed. The next factor is the power output of the solar array which is a direct relationship to the amount of sun that falls on the panels and the number of panels in an array. The lower the head, the higher the performance. To increase the output, simply add more solar panels!

Another answer is to create a gravity water supply from sunken well and create a drip flow system to all the plants. If your property slopes this could be simple and a level property may just require a small pump to create some basic pressure.
