What Are Solar Submersible Pumps
Solar submersible pumps are either DC (direct current) or AC (alternating current) electrical pumps that are capable of being submerged for long periods during its service to pump water from deep wells. This means that some submersible pumps are able to run on either DC or AC voltage and current. When using solar panels without using any inverters, DC motors have the advantage since most solar panels have DC outputs except for panels that use micro-inverters at the panel level of electrical production.
Solar submersible pumps are used in farms, off-grid installations and sometimes even in on-grid situations. Solar pumps give us that guarantee for a continued water supply when the city or town water system is not working, have very low pressure, affected by natural disasters and so on.
The system below has a maximum head or lift of 230 feet. This means that at a maximum depth of 230 feet this pump will efficiently deliver the water to the surface and up to your elevated water reservoir. This is available at Amazon. This motor is 24 VDC so it does not need any inverters. The panels alone will power up the system. Add a suitable battery and this can give you a 24/7 water supply year round. The system is rated at 3.2 GPM (gallons per minute).
Why Solar Submersible Pumps
No matter where we may live on this planet earth, water is always going to be a very valuable and critical necessity to have around. Take away water from any location on Earth and our quality of life or survival situation drastically goes down. And for us who have lived in older cities, we have grown up witnessing our water supply continue to be there for us every day. Water is always present from our faucets, showers, gardens etc. We take this water supply for granted. We know it will be always there for us. Solar power coupled with batteries give us added assurance for a continued water and electrical service.
The Dreaded Natural And Man-made Disasters
In California, we have the dreaded, LONG OVERDUE Big One, a massive earthquake coming from the well-known and talked-about San Andreas fault. They say that when this Big One hits, it could have catastrophic results. As we have a lot of our services piped in to our homes in America like water supply, natural gas, electrical services, three of our most critical sources of energy and survival services, a huge earthquake could damage a lot of these pipelines.
Electric power lines supplying homes in many areas are now buried. Could these get affected by a massive earthquake? Why is this important? In small cities outside huge metropolis like the Los Angeles area, water supplies are from deep wells. I have lived in these small cities. They depend on several deep wells and huge water reservoirs for their water supply. Will these systems survive massive earthquakes? Would you believe that even huge and older cities have deep wells located within the cities themselves? You might see some in city parks, hidden from sight by fences and bush, there some huge AC motors are quietly humming away pumping thousands if not millions of gallons to our city water supplies.
What about man-made disasters like terrorist acts against our services? We have seen in California years ago how several of these people managed to disrupt our electrical services through violence. Whether it is our electrical services, our water service or natural gas services…we cannot be so sure that they are disruption or damage proof. Should we prepare for them if we are able to?
City Dwellers And Steady Water Supply
Large and established cities have for the most part a guaranteed continued service of a 24/7 water supply. In these scenarios would it still make sense to have your own deep well and solar pump setup? Maybe not since most city residences will not have the luxury of space for digging a deep well and a solar pump installation. But in situations where you might have a backyard suitable for the project, it would not be a bad idea to have the system for some truly good reasons. Solar pumps will give you a steady source of water for drinking, watering your garden plants, a guaranteed source when your supply is disrupted by natural calamities.
Best For Off-Grid Locations
Off-grid locations where you neither have city water nor city electric service, submersible water pumps powered by a couple of solar panels and backed by a storage battery for a 24/7 water supply is a very good choice. In addition to powering up your solar water pump, you can use the extra electricity for some of your lighting. Or have a few kilowatts of solar panels combined with larger battery bank and the whole off-grid setting could be fully supported by this renewable energy setup.
Deep Well Challenges
Depending on your location, digging deep wells have challenges that are different in nature. In my present location on an island in the Philippines, my deep well of 130 feet deep cost me around a thousand bucks to dig, install the six and a half 20-foot long, 4-inch pipes, purchase and set up the pump and electric motor.
Take the same 130-foot deep well to my residence in the high desert of California and the whole scenario drastically changes. First, the water is available only at a much deeper location like 300-600 feet or deeper. Here we have to use a submersible pump. Then the cost of digging this well will run you up to around $30K vice the $1k deep well in the Philippines! Indeed the cost PLUS some very tough federal laws in the US that apply to digging your own well could just about kill your dreams of building or acquiring one. Some folks however still manage to get it done and end up producing more in an agricultural setting. So depending on your end-project and your determination to do it, this types of undertaking is still doable in many places in the United States of America but not without its challenges.
On the other hand I have seen other locations where a deep well supplying a household only had to go down 30 feet. That is a pipe and a half deep (20-foot pipes). Your cost will be a lot less in this kind of scenario.
Below is one of the best brands in submersible pumps. Grundos submersible pumps can pump from several hundred feet. The model below is rated with a maximum head of 655 feet and that is very deep. This is the depth that the pump will lift water efficiently. Available and cheapest at Amazon.
Rural America Has Its Survival Edge
Comparing a huge metropolis and rural areas when it comes to surviving natural disasters? I suppose it all depends on the disaster itself. Which is best suited to prepare for the several natural disasters lined up against mankind? My take: rural areas will fare better. How? One reason is land. With some acreage we can grow our food. With some acreage we can dig our wells. With yet a few more acreage we can set up solar panels and battery banks. We can also build our survival shelter aside from our homes.
Rural areas may also not make it to the list of nuclear targets by our nuclear enemies. Big cities especially near military installations? I would not want to live near one if there was to be a nuclear holocaust. Anyway, we are getting too far off our topic of solar submersible pumps and has shifted to survival. In the Navy, during drills on ships, we are told to brace for shock as an ‘imagined’ nuclear explosion from several miles away is announced on the intercom. We sailors know better. We tell each other to never mind about ‘bracing for shock’ and instead we remind each other to bend over and kiss our behind goodbye. But as far as survival, it is best to prepare for the unknown. We just never know.
