Navitas Solar Launches Solar Water Pumps 56 energetica INDIA- Mar_2022 To provide a more sustainable and envi- ronmental friendly solution to the water shortage and storage issues in remote ar- eas, Navitas Solar has proudly launched Solar Water Pumps. These pumps are an ideal combination of Green Energy, Economy, and Reliability. The World has been drawing water us- ing pumps by Diesel, IC engines, or utility electricity. Yet, the biggest issue with Diesel pumps is that they have a hazardous impact on the environment. Even the pumps powered by utility electricity are difficult to use in remote areas due to the unavailability of the supply. Hence, Navitas Solar has come up with the Solar Water Pumps. They have a significantly lower environmen - tal impact compared to other pumps since they emit less pollution and help in carbon footprint reduction. We can use them in remote areas where grid connectivity is not yet established or is uncertain. Electricity produced by the Photovoltaic Panels (PV) of a Solar sys- tem is used to drive these pumps. A submersible pump can lift up to 650ft of water and can be installed in large wells. When the well water is 20ft or more above the surface, the submers- ible pumps can operate directly to turn off Batteries, Solar Panels, and in some cases, Electricity on their own. They pump the water during the day and store it in tanks for future use. How- ever, the only problem in bad weather conditions is that the water cannot be pumped due to the lack of sunlight. Thus, it is advisable to store the water only in good climate conditions. For the submersible pumps, the maximum rec- ommended pump depth is 50m. Hence they are used in deep-water wells and undrilled areas. We can use them to wa- ter livestock, Aerate ponds, home water systems, irrigation, pressurization, and pump wells. However, when the well water supply depth is less than 20ft from the ground, we recommend using a Surface-Mo- no Block Solar Water Pump, also de- signed by Navitas Solar. These pumps can pump water up to 200ft or more but cannot pump very high water from deep wells. They can easily lift water from depths of up to 20m. Applications of solar pump: • Livestock watering • Home water systems • Pressurization • Well pumping • Irrigation for farming • Drinking and cooking • Industrial water processing • Fountains • Pond/ aquarium/ Swimming pool fil - tration Features of solar pump: • Long-life support and mainte- nance-free • Easy installation with internal com- biner box • A high technology control unit, wa- ter pump, and motor • Maximizing energy efficiency (~+40%) with internal MPPT module • Shorter payback period against DGs • Zero operating costs • Battery-free, direct drive system • Possibility to work with a generator or grid electricity in case of require- ment Advantages of solar pump: • No need for fuel • Easy to move • Doesn’t require utility supply PRODUCT FEATURE • Used in remote areas • High durability and performance • Long service life • Environmentally friendly Components of solar pumps: • Pump and motor: » » Extremely efficient PMSM/ BLDC motors » » Stainless steel rotor » » Rare-earth magnets that can withstand 160o C high-quality ceramic carbon thrust bearing » » Leak-proof motor filled with water for frictionless operation » » 100% stainless steel AISI304 parts for submersible application » » Sand guard » » Warranted for 5 years • Controller: It matches the output and input pow- er of the pump and solar panels and provides voltage protection. With the pump controller, the operator adjusts the pump pressure, flow, frequency, op - erational times, etc. According to the end-use requirements, there are various categories of pump controllers to choose from, depending on the solar pump mo- tors (AC or DC). » » Built-in MPPT for maximum output » » Sensor less dry running pro tects the controller. Tested as per MNRE and BIS requirement » » Warranted for 5 years » » Remote monitoring » » Remote start-up and stop » » Short circuit protected » » IP54 and IP65 certified controllers
