An algorithm for sizing photovoltaic pumping systems for tomatoes irrigation

This paper presents an algorithm to optimize the size of the components of a photovoltaic pumping installation, composed of photovoltaic panels and a battery bank. The decision is made on the basis of the measured Photovoltaic Panel Generation, the required power for the load, the needed water quantity for the crops and the correct operation of the battery. The algorithm aims to ensure the system autonomy, minimize the unused energy and fulfill the water demand. Some tests of the algorithm are shown in order to demonstrate that the approach fulfills these objectives.
