  • mpProposal ForSolar Water Pump LOBEL SOLAR POWER SYSTEM Er Chintan Gandhi 09327007854 lobelpower@gmail.com www.lobelpower.comLOBEL SOLAR POWER SYSTEM
  • Budgetary Proposal for a solar pumping solution We are pleased to introduce ourselves as reputed solar system integrators of solar energysolutions. Our solutions cover solar installations for residences, commercial and industrial,utility-scale power plants for PV and Thermal both.System Layout The solar pump system consists of solar panels on a mounting structure, a pompcontroller, an electric pump and a storage tank for water. The big advantage of the solarpump is that there is no battery necessary to back-up the solar power. The pump isconnected to solar panels, so water is pumped from low to high level in case the sunshines. The water is buffered in the tank that is mounted at a higher level than the taps.In this way there is pressure on the taps and there is water available if the sun is notshining. The function of the water tank is comparable to the function of the battery. To obtain a good match between solar panels and the pump, the pump controller isconnected in between. This controller makes the solar pump a unique product. Not anyother pump can be used, on the contrary! The controller converts the direct current from thesolar panels into alternating current with a frequency that depends to the irradiation. At lowirradiation, eg. in the morning at sunrise, the pump will be driven by a slowly rotating engine.The speed of rotation will increase when the sun rises in the course of the day. 2LOBEL SOLAR POWER SYSTEM
  • As per your requirement for solar pumping solution, we are pleased to submit the followingproposal. For the pumping system, we propose to use the submersible/surface pumps. Thepump is accompanied with a solar drive, which will convert the DC solar power to AC andoperate the pump. FIGURE 1 SCHEMATIC OF A TYPICAL SOLAR PUMPING SYSTEM Sunlight captured by solar panels is converted into DC electricity. This DCelectricity is collected from all the solar panels and is passed through a solar Drive,which will power the Solar Pump. LOBEL will install a similar Solar Pumping System atyour facility. A survey will be conducted at your facility. This proposal describes system design, its components, and systeminstallation process. The system will consist of the following major components: 1. Photovoltaic panels (High Power output, high efficiency panels) 2. Solar Drive for converting DC to AC 3. Mounting Structure and Accessories 4. Cables and Connectors 3LOBEL SOLAR POWER SYSTEM
  • Design scheme Design of solar pump system starts with a survey of needs and location data(step 1-3). With this result, a most appropriate pump and solar panel combination isobtained to design the right system configuration (step 4-6).Step1: Water need The first, the most logical, but also the most difficult question concerns the waterrequirement. Related to this question is the purpose of the water. Is it for domestic applications,for a village or for irrigation? The best source for your information is to ask and measure on site.To help you finding a first indication, we can help you with some index numbers. 100 liters per person per day. This is including water for bathroom, shower, dishes, cloth washing and so. Westernized family Not westernized family With20 Liters per person per day you are probably rather high Index number of WHO: 40 Liter per person /day. The real need isNot westernized village Probably lower. Not answerable with an Index number. What Is the crop, How much Sunshine you have to compensate (evaporation) and Irrigation what is the rain Supply on site? Depth of water? Area of land? These questions should be answered with local knowledge. It’s also not bad to ask specialist or to look in an irrigation manual.Step2: pump head Step 2 of the investigation to local resources is to answer the where-question:Where does the water come from and where should it be pumped? What is the distancebetween the well? What is the water level in the well? At what height should the waterbe stored? To answer these questions, we distinguish the static and the dynamic head.Total head = Static head + dynamic head (friction in the pipe)Static head The static head is the difference between water level in the storage tank and thewell. Notice that the water level in the well is not always identical to the ground water level.If the capacity of the well is limited, the water level in the well can decrease substantially.LOBEL SOLAR POWER SYSTEM
  • Dynamic Head (Friction in the pipe) The pipe length between the well and tap is also relevant. The water is restrainedby the friction in the pipe, especially if there are benches in it and if the inner diameter isrelatively small. As a result, the total head is apparently more than the vertical differencebetween the water level of well and tank. The magnitude of this dynamic head dependson the inner diameter of the pipe and the flow. The table below presents the meters toadd to the static head per 100 meter pipe to calculate the total head. The dynamic head in meters, per 100 meter of pipe. This head is dependent to thecombination of inner diameter of the pipe and the flow. The table gives the values of plastic pipe.

The NASA developed a databasebased on information from satellites (cloud configurations during a long period). Thedatabase gives a good estimation of the solar irradiance on the ground.Step4: System configurations The capacity of the storage tank will determine the reliability of the water supply. Asa rule of thumb, this capacity should be the double of the estimated daily water demand. 5LOBEL SOLAR POWER SYSTEM
  • The scheme is based on storage in a buffer tank. In fact storage of water at acertain level is a method to buffer solar energy in potential energy. The main advantageis that no batteries are needed. Moreover, there is always water pressure at the taps.(On the condition that the level of the taps is enough under the tank level).Step5: Choice of the pumpThe pump selection is mainly based on the water demand and water head.Surface Mounted Pumps At lower pump heads (typically some meters, maximal 14 meter) a surface mountedpump could provide the best solution.Submersible Pump At larger pump heads, the submersible pump is a better choice. This pump goesunder water in the well or bore hole.Step6: Solar Panels Top quality, high efficiency solar panels will be used in the system.  PV panels use high efficiency polycrystalline cells and are assembled with top-quality raw materials sourced globally Panels are tested in accordance with IEC 61215, IEC 61730, TUV and UL 1703 certified.  Best-in-class performance ratings proven by field installations  25 year power warranty  Higher strength to withstand wind loads up to 200km/hr  6LOBEL SOLAR POWER SYSTEM
  • Mounting The panels will be Pole mounted four panels on each pole. Since PV panels should ideallyface south, mounting will be done using special mounts and techniques to align the panelsdue south. Each panel will be tilted at required angle (degrees) to capture the maximumsouthern sun. Mounting hardware will be anchored using suitable bolts/cementing.Budgetary Sheet LOBEL SOLAR PUMPING SOLUTION: Selection Guideline Discharge Range Motor (in Liters Per Day Head Module Solar Pump Sl.
