Summary:

In India where agriculture is the base of the economy, through till date many of the area where land is very fertile but due to the unavailability of the electric supply, irrigation is almost impossible or very costly To lift water for irrigation, solar pumping systems are rapidly becoming more popular for agricultural irrigation, horticulture farms, forestry, fish farming, city parks, tourist sites, resorts, and even landscapes and fountains in residential areas can be run with solar power.

Solution:

Solar photovoltaic pumping system consists of three components: • PV solar panels • Pump Inverter (VFD) and • Three-phase AC water pump. Solar PV panels connected in series & parallel combination to achieve the desired voltage and current necessary to drive the ac pump. The power rating of the solar array will be suitable to the design if the pump. Mounting structure will ensure the long-life hassle-free operation provided with fix mounting or tracking system

Pump inverter can control and adjust for the system. It can convert DC produced by solar panels into AC to drive the water pump. According to the sunlight intensity to adjust pump speed, the output power close to the solar array maximum power; when the sunshine is sufficient, pump speed does not exceed the rated speed; when sunlight is insufficient, it will automatic stop working according to the minimum operating frequency. Water pump is driven by three phase AC inverter. Pumping water from the deep well or rivers and lakes is poured into the water tank/pool, or directly connect irrigation system and fountain systems.
