The extraction of water in small and large scales is an application of great transcendence at present; it has an impact on rural communities where there is no conventional electricity. The photovoltaic pumping systems are characterized by high reliability, long duration and minimum maintenance, which translates into a lower long-term cost when compared to the electric grid or generator set. In addition, it does not require the use of an operator and has less impact on water, air and noise pollution. The drive line is: a 10 HP submersible electric pump, with a flow rate of 4.5 l/s, ADT of 90 m, drive length 487.5 m, and a volume of 90 m^3. The generation system is 48 photovoltaic modules of 240 Wp. Model SM-230MA12, with a minimum generation power of 11.14 kW. The cost of operation with conventional technology is US $ 2,468.00, the annual energy cost is US $ 11,220.00, and the cost of operation with photovoltaic technology is US $ 3,380.00 and the annual saving is US $ 15,370.00, showing that its operation is according to the HSP and whose estimated return on investment is 2 years. |
