If you can get more power, add more. If your well is deeper than 25 feet, youll need to use a different type of pump to pump water to the surface. The pump will have a minimum current draw when stalled and no pumping is taking place. You can connect the well pump directly to solar power. A 10 x 3000 watt solar array is going to produce 30000 watts an hour if they perform at peak level.
While By Sheri Jones
With the preliminaries out of the way, the best solution is to install a solar system that supplies power to your main power panel for your whole house, including your pump equipment! Installing solar panels dedicated only to your water needs mean that this solar equipment sits idly by doing nothing when the sun is shining and no water is being used. This is more efficient than connecting the pump directly to the panel because youre using the battery as an intermediary between the two devices.The downside is that you need to have a way to store the solar panels energy in the form of a battery. Large 2 volt batteries would be better than small 12 volt batteriesnever skimp on copper either. Or purchasing deep well solar pump and use solar panels. Selecting the right pump for your specific application can reduce the size and cost of the solar array that will be required to provide the power. A solar panel kit is for you if you require a self-contained system to pump water. After all, if youre relying on your well for water, you dont want to lose access to water just because you switch to solar. Solar Pump Kit: if you bought a solar pump kit, all the required parts are there. By Patrice Lewis
it is also more practical to add more components this way than set up a new system based on the kit. Connect the well pump to the inverter using the appropriate wirers and connectors. Issue #126 November/December, 2010
These links are not intended to show the exact product for your specific application, rather a generic example of the product referenced. This is getting a little crazy and if you implement this system it will look like a Rub-Goldberg contraption, overly complex and likely not be very reliable. Even submersible pumps designed to go a hundred feet plus deep have a straightforward setup. To answer that question we need to know the power requirements of a well pump. Not such a far-fetched idea, The return of home emergency shelters takes on a dual-purpose approach, A Childs Garden More than Childs Play. Its not yet commonplace but its something to consider. System 1) 15 Renogy 300w + 4 250W Astronergy panels, Midnight 200 CC, 8 Trojan L16 bat., Schneider XW6848 NA inverter, AC-Delco 6000w gen. System 2) 8 YingLi 250W panels, Midnight 200CC, three 8V Rolls batteries, Schneider Conext 4024 inverter (workshop). If youre using a solar generator, the inverter is already built-in so you just need to connect the well pump to the system. For our example, the pump would need to have a minimum lift of (30 feet + 20 feet to lowest water level) + 50 feet elevation of the tank + 3 feet tank water depth = 103 feet total pumping head. If you power the well with solar, then you need some way to get power to the filter, tank and booster pumps. Its a valid question! How Do You Power a Well Pump in A Power Outage? For runs over 100 feet, I suggest using 3/4-inch PVC piping. A pressure booster system is the most complicated type of solar well pump kit. These solar applications made economic sense because the location was too remote to run a long power line. This means that dedicated solar pumping solutions are more expensiveand they arent any more efficient at converting electrical energy to flowing water. Most farm and ranch applications should have the modules and pump controller mounted on a raised pole to stay above snow drifts and potential damage from animals. You can settle for a smaller battery bank if you combine it with a solar array. You can use a solar powered water pumping kit to supplement your current electrical system.
This solar system should be sized to run your essential needs during a power outage, be grid tied to feed excess power back to the grid, and have a battery bank capable of getting you through a few days of power shutoffs or bad weather (or smoke obscuring the sun if you live in a fire prone area). Specialty, more expensive, pump controllers may be required. However, if you need to use water for more demanding tasks like taking a shower or washing your clothes, then youll need a pump and tank system or a pressure booster system. 
Any suggestions, I need a system to pump water uphill about 100feet and 250 feet over to storage tanks. You can use this calculator to determine how much solar power you need in your solar system. The well will be 100 feet deep and the pump will be positioned 80 feet down. When the sun is shining, the system is pumping, when the sun is not shining, the system is offsimple. When measuring the distance a submerged pump must raise water, you do not start with how far down the pump is in the well. The first thing youll need to decide is what type of system you need. You charge the battery with solar panels and then run the pump off the battery. A 48-volt DC pump will require a minimum of four nominal 12-volt solar modules (412). Now all you have to do is get a solar power source that meets those requirements. Centrifugal pumps are generally not very efficient.
We have a 1100 watt solar array, hooked into a midnight charge controller then to a total of 6 total 12v batteries then to a magna truesign inverter then to a electrical box were we have a 240v submersible pump hooked in to two 15 amp breakers then it runs in the house to the pressure pump switch then out to the pump. But if your well pump only need twice the starting watts, you can reduce the number of solar panels. For example, lets say we want to fill an open water tank (no pressure) that is on the top of a small hill. The starting watt is what a well pump needs, to initialize, similar to a refrigerator. Yes, solar panels can be used to power a water pump. You have free energy. Solar power is also a renewable resource, so you are being eco friendly even if the pump has to work continuously. As the voltage is increased, pump rotation and water pumping is increased as long as enough current is available.

Yes, you can run a well pump on solar power. My 240VAC Grunfos pump uses 38amps at startup, and 9.5 amps running. Once youve decided what type of system you need, youll need to consider the following factors: The amount of power required to run a well pump depends on the depth of the well, the flow rate of the pump, and the average daily sunlight hours in your area. You could use a hand pump for emergency or backup, However that water is not considered fit for consumption by humans. The Truth about Solar Lights: How Long Do They Really Last? He has pressure tank on the surface but we will disable that and send water directly to the big pond and collect there. inverter/chgr | Iota 48V/15A charger | Morningstar 60A MPPT | 48V, 800A More panels? Solar panels are designed to generate electricity, and pumps are designed to convert that electricity into mechanical energy.If you connect a pump directly to a solar panel, youre essentially bypassing the pumps efficiency and wasting some of the solar panels potential output.Use a solar panel to charge a 12 volt battery and then use the battery to power the pump. Save my name, email, and website in this browser for the next time I comment. If we use 1/2-inch PVC pipe, the loss would be 8.9 feet head (3.56 x 250/100). You can, but it might not be the most efficient way to do it. Solar panels are easy to clean and low maintenance. We notice the water level is only 30 feet below the surface, but will probably drop considerably when the pumping starts unless it is a very fast refilling well.
Why? The amount of water that a solar well pump can provide depends on several factors, including: As a general rule of thumb, a solar well pump can provide between two and four gallons of water per minute. At 240VAC that corresponds to 9100 and 2300 watts. Is it right for you?
Each residential-size solar module will produce a fairly constant 17-volts output at almost any level of sunlight. A pole mount also allows easier adjustment of module tilt and east-west orientation during initial setup to achieve the best overall year-round performance. b) Frequently there are storage tanks, booster pumps and water filters involved in the process of providing water for a rural home. that is why you should still have at least 3000 watts of solar power. Remember, the purpose of the storage tank or drinking trough is to allow a very slow water flow constantly pumping throughout the day, to build up a large volume of water to supply brief periods of high water usage. Why does your customer want to do what you are asking? Instead of a deep well, you may need to pump from a lake or pond at a lower level up to a storage tank. Successful implementation of solar doesnt just require the right equipment, it also means a correct understanding of the equipment, its capabilities and limitations. Because the solar system is designed for the amount of power you used based on utility records. There are many things parents can give their children, other than plastic toys or a few bucks to play video games at the mall. I have a Schneider XW+6848, which is designed to handle that surge current. It's fueled by 4500 watts of solar. Still PWS solar pump is giving 3 yrs warranty. This is my first post and I tried to state every details. If we increased the pipe size to 3/4-inch PVC, the loss would be 2.3 feet head (0.90 x 250/100). This is an inefficient deployment of technology. We listed the solar panel requirements for starting watts that are three times higher than running.

Khaki Campbell ducks The other egg layer, Finding the best dog for the country life, Kinder goats A small breed for milk and meat, Llamas guarding sheep? Most wells are connected, running and relatively close to where the water is needed and power is available, what is the best solution. If the panels drop the output will drop below 3000 watts. Low voltage DC pumps designed to operate on solar power are not designed like 220-volt AC water pumps. The running watts is what a well pump consumes while it runs. These are all in one solutions containing all the components you need to run a well pump on solar power. For more details, click here. It consists of a solar panel, a motor, and a pump. As you will notice, he starting watt capacity can be two or three times the running watts. Can I Run a Pump Directly from A Solar Panel? Best approach is switch to DC positive displacement pump in the well pumping to gravity tank in an elevated location. It will also avoid trying to operate the pump in a stalled condition when solar output is too low. ), How to Choose the Best Solar Well Pump Kit. ), Why Are My Solar Lights Not Working at Night? These pumps come in various shapes and sizes, but their wattage use are in this range. As an example, lets say you need to calculate the piping pressure loss for a 2-gallon per minute flow through 250 feet of pipe. 2) Is the well at a very remote location without access to power? In this issue I will address another form of free water pumping. Or what we need to add? Solar panels convert sunlight into electricity, and pumps use electricity to convert mechanical energy.There are a few different ways to connect a pump to solar panels, but the most efficient way is to use a battery as an intermediary between the two devices and connect everything together in your solar system. Some pumps are designed to work for shallow wells while others are specific for deep wells. Youll need to consult with your local water authority or installer to see if your particular well can be powered by the sun. I hear some reall weird questions on taking out a working pump system and playing around with imported pumps of unknown quality. I myself run my pump solely on solar now, but I know exactly what my numbers are. Please note that Amazon links have been provided to show illustrations of products mentioned in this blog.

However, if you have a large well, youll need a more powerful solar panel and motor to accommodate it. To keep it simple: check the starting wattage of the well pump. Thats why its no surprise that many are asking, can you run a well pump on solar power? Unfortunately, water pumps use a lot of power and could drive your electric bill sky high. (All You Need To Know!). Unlike AC powered devices which should not be directly connected to solar power, you can hook up a DC well pump directly to solar. Solar power provides a lot of benefits, and this applies to well pumps too. Notice how the same pump will have a substantially reduced flow rate as this head pressure is increased. Likely your system is far too small. Are Solar Trickle Chargers Any Good? Any ideas why? As technology improves, expect efficiency to improve even more. A battery allows you to run a well pump even if there is no sunlight to power the solar panels. The bummer is 2 wire pump is not readily converted to VF drive, Three wire pumps with an external capacitor box can be converted with a Franklin monodrive conversion but its pricey. The motor then uses this electricity to power the pump, which draws water from the well and sends it to the tank. Why do people love solar power? Well also give some tips on how to get the most out of your solar system so that you can keep your well pump running even during a power outage. We suggest going with Renogy 12V Monocrystalline Solar Panels because they are proven effective and reliable. If you are not familiar with electrical safety procedures then you should not attempt working with the electrical equipment mentioned in this blog as it represents a significant hazard of electrical shock. So, since customer will not use pressure tank, and static water level is 30', no need to place solar pump more 100' deep, Pump head calculation is only 30' seller says (from static water level (30') to ground surface). Well pumps do not run continuously, with most running for 20 to 25 minutes an hour. (Panel model VSUN 144MH), VMPP: 40.2V VOC: 40.2V IMPP: 9.59A Maximum System Voltage 1500V, How many solar panel he needs to run this 230V solar pump?

So what is the best solution for wells that are already connected and in use?
But converting your existing well pump is not that difficult either. In addition to the elevation head (feet) your pump must lift the water from a low pond or drilled well up to a storage tank, it also must overcome the resistance to flow of the pipe. I need suggestion for those who have experience about. Just like solar pump kits, you can put these components together in no time. However, you may visit "Cookie Settings" to provide a controlled consent. Customers frequently call asking about converting their well pump to solar so that they can have water when the power is out. The longer you run the pump, the more battery power is needed.
Bear in mind these are only meant to give you an idea. Issue #69 May/June, 2001 A 1/3 HP well pump needs 3000 watts of solar power. Centrifugal well pumps draw a lot of starting inrush current. The following information is taken from my book titled, Achieving Energy IndependenceOne Step at a Time. All deep water wells for human consumption are much deeper, hence a submersible pump is required. You start by measuring from the above ground surface down to the lowest level the well water will be during pumping. A DC water pump is designed to pump using the absolute minimum of electrical power.
The 12V MS2812 has a 5 second peak of 3900 watts. The sun only shines in the day (at least the last time I checked) which means that a solar pump without a battery bank would be useless at night, in overcast weather or smokey days. Six 12V batteries wired in parallel is a very poor configuration. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); You have entered an incorrect email address! At least you have the option to run the pump on a battery, generator or on the grid, depending on your needs. Once you pay for the pump and the solar system, thats it. Each has its own pros and cons and you have to decide which will work best for your situation. There are two fundamental questions we ask when working with a customer to help them with the best solution: 1) Is the well an already existing well or is it a well that is planned for the future?

This category only includes cookies that ensures basic functionalities and security features of the website. I simply determined how much power my 240VAC pump required, and designed a solar system to meet that. Solar power well pump installation shouldnt take more than 20 minutes. This means the solar panels do not need to produce 1500 or 3000 watts continuously. A solar pump controller will convert any excess voltage of the solar array to more output current. But if you want to do the calculations manually, this guide can help. And thanks to competition, the cost of these systems are going down faster than before. That applies to solar powered well pumps too. Although the flow rate can be less than one gallon per minute (GPM) for the smaller pump sizes, this small flow will be fairly constant throughout the solar day (9 AM to 3 PM for most locations). During less than ideal solar periods, the current output of the solar module(s) can be below the amp draw required for the pump to begin pumping. So, no need to pull a pump out of the ground and replace it.
As I stated earlier, for small-flow DC pumping applications, if you oversize the piping to reduce friction loss, you could increase sediment problems at these low flow data rates. The size of your well will also determine which type of system is best for you. These are often located far from one another. As flow rates increase, a larger pipe may be unavoidable on longer pipe runs.

I installed my panels on rotating ground mounts, and by rotating the panel East in the morning, I can turn on my pump at 8am. This will require using two or more nominal 12-volt solar modules to provide the higher voltage. When I gave above information to the seller, he said because pressure tank installed, AC pump placed so deep. 3000 watts is the minimum required. It isnt your power is free as long as you use the same amount of power you used before installing the solar equipment. This also means the rest of the solar power is free and can be used to run other appliances and devices. If your well is suitable then there are several different ways you can go about powering it: A solar powered water pump using direct sunlight as a power source is a great way to save money on your energy bill. If you live in a rural area or need to access water underground, youll need to buy a well pump. You may want to consult the DC pump distributor to determine the size of solar array that will be required for your specific application. If youre a rancher or own some farmland, an all in one kit will save you a lot of trouble.A solar pump kit is not for you if you already have a solar system at home. Copyright 2019 Self-Reliance Publications LLC. . If you want to convert feet head to pounds per square inch (PSI) pressure, divide by 2.31 which equals 45 PSI (103/2.31). Table 3 provides a size comparison of several popular models of smaller DC pumps, and the relationship of pump flow (GPM) to pump head (feet). For high pumping heads (feet of lift) or high flow rates, you may want to consider buying a higher voltage DC pump instead of a smaller 12-volt DC pump.
