PROJECT PROPOSAL - Conclusion

In all systems there are losses due to such things as voltage losses as the electricity is carried across the wires, batteries and inverters not being 100 percent efficient, and other factors. These efficiency losses vary from component to component, and from system to system and can be as high as 25 percent. Otherwise using tracking system is better to increase the system output compare to fix position in term of cost and technical performance. The solar water pumping system able to support the small scale of paddy field from quarter acre up to seven acre. This system is complete with water level control for water reservoir and paddy field because the paddy plantation behavior is sensitive to water level. This project able to helps the farmer to improve the paddy production for outside the granary of paddy field.

Since the increase in price per increase in unit power output of a photovoltaic system is greater than that for a diesel, gasoline, or electric system, photovoltaic power is more cost competitive when the irrigation system with which it operates has a low total dynamic head. For this reason, photovoltaic power is more cost-competitive when used to power a micro irrigation system as compared to an overhead sprinkler system. Photovoltaic power for irrigation is cost-competitive with traditional energy sources for small, remote applications, if the total system design and utilization timing is carefully considered and organized to use the solar energy as efficiently as possible. In the future, when the prices of fossil fuels rise and the economic advantages of mass production reduce the peak watt cost of the photovoltaic cell, photovoltaic power will become more cost-competitive and more common.

PV solar water pump system to solve problems of agricultural water conservancy and desert control with agricultural farmland decrease, the desert area continues to expand, the extreme arid climate impact on food production, solving water supply has become the root of problem of agriculture. Compared with the traditional diesel pump and electric pump irrigation, solar pump has great advantage. It will become the main way of agricultural irrigation in the future, has a wide application prospect.
