Thus, lack of irrigation systems directly affects more than 3.8 million existing small farms whose production is dependent on weather conditions. Renovatio Solar wants to address this issue through a new irrigation concept that uses energy produced by the solar panels to pump underground water and irrigate crops.
Renovatio Solar built the first photovoltaic park in Romania in 2010, and since then has developed over 50 MW in different areas of the country. In 2013, the company decided to explore new areas for photovoltaic energy, namely agricultural irrigation.
Along with changing the law to support renewable, we decided to focus on projects to sustain without green certificates scheme. A project that has great importance for Romania is the solar irrigation. Why? Romania has so really need to get out of the " Middle Ages. '" When good weather year, everyone is quiet, the production is fantasti , feels and growth, but when we have a dry year as it was in 2012, is a disaster. We can not stay to pray to rain at the right time ! Just when you need water when heat, can produce energy from solar sources, without needing a connection to the national grid power and irrigate, "said Dragos Constantinescu Renovatio Solar administrator.
The principle of operation of such an irrigation system is simple. Solar panels feed pump that draws water from underground or from a source in proximity on the surface, which is stored in a collection tank. A second pump, all powered by solar energy, stored water pushes towards culture.
Small and medium farmers, the main target
As you can see, there is no need for large irrigation systems. Water is removed from lakes or rivers and transported long distances. Our strategy is to remove water from the proximity of the project and to irrigate areas of six to ten acres. It is thought modular. Where you need to irrigate, there will then plant up. This gives flexibility and makes it possible that small farmers have access to this type of irrigation. This modular structure has great advantages, " said manager Renovatio Solar.
According to him, the irrigation system during the communist period was not viable because the electricity used to power pumps became very expensive and pumping were ineffective. To these are added the very high water losses in irrigation canals route.
We will focus on systems that irrigate the drop and the more efficient use of water. If vegetable plantations, this irrigation method brings the highest profits per hectare and hence a short payback, "said Dragos Constantinescu .
Solar irrigation projects developed by Renovatio Solar are ideal for vegetable crops, orchards, vineyards and grape – seed any crops: corn, sunflower, etc. .
Seed crops always have a higher value, and also invest its manufacturer depreciation is also done in a shorter period, said Dragos Constantinescu.
