As hybrid solutions are gaining more and more space in strategy two consumers, whether for economic or technical reasons. This name has been adopted for systems that have, for example, diesel generators associated with other sources such as photovoltaic and wind.
The combination solar and diesel is advantageous as it provides a trusted mode de isolated power supply without the intensive use of fossil fuel. In locations already served by generators, the addition of Photovoltaic systems operating in parallelism has the effect of reduce the cost with fuel, in addition to adding reliability and reinforcing the power supply autonomy of consumer loads.
Such projects are already a reality on any scale, from microgeneration to centralized generation. Among the many consumers who are investing in this solution is rural producer Henrique Reges de Carvalho, which connected a hybrid system, located in your farm in the municipality of Baianópolis (BA), in February this year.
The enterprise – which has the Fortlev Solar as a distributor of the equipment and JA Solar as a supplier of modules – is aimed at irrigation, integrating Photovoltaics e diesel generators.
According to engineer Paulo Henrique Ferreira Campos, Director of Operations and owner of Genwatt Engineering, the integrator company responsible for the project, the end client invested in a hybrid solution due to some factors, the first was due to the scarcity de water in the region. “The client drilled three artesian wells and managed to access the aquifer. Each well has a flow rate of approximately 300 liters of water per hour.”
“The other problem was the lack de electricity. Wells were drilled, but there was no power from the utility company. Then, the need arose to place a most advantageous source, cheaper and more environmentally friendly”, he emphasized.
Faced with this scenario, the owner turned to the solar pumping to remove water from the well. “It is autonomous pumping, in which water is removed and thrown into a lagoon, using only solar s”.
"In case of pivot, the autonomous system does not apply due to flow fluctuation. Therefore, the customer placed the diesel generator to feed the pivots with hybrid photovoltaic energy em parallel to provide saving of diesel”, added Ferreira.
Project Details
According to the engineer, first the water is pumped from the well to the artificial lagoon using an autonomous pumping system with 125 HP of power. The 200 HP pivot pump drains water from the pond to the pivots for irrigation. For this to happen, the photovoltaic source and the diesel generator act as the electrical grid and power the equipment.
