Super Fitness Health BlogWater Pumps Utilizing Solar Energy
We have seen some controversy every now and then with regards to pumping water and also the most efficient water pumps available in the market. I’ve been doing a bit of work in Nigeria and setting up rain water collection systems and in some regions there’s no grid power therefore solar is the only option to fill up the overhead reservoirs. This site contains really good information on how to build your own solar panel. I am working with a organization to design a new 12v permanent magnet motor and pump model. More than likely 2 pumping systems will be produced. One which has got a low head close to 20′ to fill up overhead tanks and a second which will need around 2.5 gallons per minute volume at about 40-60 pounds per square inch to supply typical water equipment in the home.
Be sure to tell me if these measurements seem suitable to the markets there as well. We’re presently looking into modern cavity water pumps since they tend to work efficiently. Other models and capacities may be looked at as we progress. We currently are not looking into designing a piston pump motor since they are already available in the market. This web page has excellent information about the best solar panels. We are considering sizing the magnetic generator at 100w as this way it will run on a large solar panel with no need of batteries if desired.
If a piston water pump already exists, why build a totally new water pump? I originally had a pm dc continuous motor attached to the piston pump, and it drew water up 25′ and also pressurized it to 60 pounds. quickly and easily at 6gpm. Energy consumption was based on pressure primarily. When I dropped it back to forty pounds per square inch this minimized current flow.

We are doing gardening over two acres. I have got so far around 9 DIGG (manufacturer) LCD water timers dispensing trickle irrigation from a well for the numerous lawn areas. These electronic timers happen to be powered by a single 9V battery. Originally I tried very costly duracell batteries, They power the electronic timers for a few months, however they are costly to change and might at some point become hard to get. So I have recently changed to 300 MAH NiMh 9v batteries. They don’t keep working nearly as long as the duracells given that the latter will be about 560 MAH capacity, however, the timers function alright at the slightly lower voltage.
It occurred to me that I could change them to work with 12V solar panels. I am a little bit vague now about the actual circuits needed, without having dealt with any sort of form of circuitry in a long time. The batteries used today are BP brand and after charging show 9.4 volts no-load. Our battery charger output voltage no-load is 11.6 volts. I’d like to keep the voltage to the timer stable using a zener, because I presume there’s a large amount of difference between the initiated / valve-open and deactivated current flow. But as the batteries happen to be 9.4 volt (as opposed to the lower 8.4 volt NiMh batteries), I do not need much voltage drop at all. The idea is that overnight, the NiMh batteries will keep our timer powered. The solenoid valve wouldn’t even run during the night, it will switch on just once a day for six minutes or so. There may be I believe not much current drain if the valve is not open, it has an Liquid crystal display panel. This eliminates the challenge of losing crops a result of the timer battery dying (already occurred). But, I’m worried about what’s going to happen to our batteries if they are repeatedly recharging on a daily basis, perhaps they may fail from over-charging? Consequently I would possibly have to add a peak-detect charging circuit (a sizable costly unwanted effect).
