Solar Water Pumping: The Most Ecological and Economical Way To Pump Water

Solar water pumping is the name given to the pumps that, instead of being powered by electric current, use solar energy. Our country has areas that are suffering from serious problems of desertification, access to water is unequal and unfortunately, there are areas where it is scarce. On the other hand, there are also areas in which there is no electricity supply because they are rural zones that are not urbanized and where it is not possible to obtain energy from the grid.

Solar submersible pumps are ideal for use in many environments – after all, many of the most remote areas in this country get plenty of sunshine. Solar pumps are a popular choice for watering livestock, crop irrigation, industrial water supply, and even residential and swimming pool applications. So what are the benefits?

  • Solar panels can be reliable, even in regional and remote areas.

They make an ideal choice when grid power is irregular or unavailable. When properly serviced and maintained and with adequate water storage, solar pumps offer great reliability. Some systems even offer apps to help you remotely monitor performance and flow rate.

  • They have extremely low operating costs.

One of the major advantages of a solar pump is that its energy comes straight from the sun, lowering operating costs and its environmental footprint.

  • They’re easy to transport and relocate.

Need to move a large mob of stock, or change your pump location based on the seasons? Depending on your system and site, solar water pump systems can be shifted relatively easily.

  • Solar pumps are generally low-maintenance.

Upkeep is typically minimal compared to grid power or generators – an important factor when these pumps are often used hundreds of kilometres from service bases. If PV panels lose efficiency, they can be replaced separately to the whole system.

  • Productivity increases in times of need.

When it’s hot and sunny people tend to use more water, and livestock will hang closer to water troughs. A solar water pump moves more water in sunny weather and slows appropriately when it’s overcast or raining, with the option to store a backup supply if your storage tank is adequately sized.


The possibilities for solar pump systems

Solar panels can be designed in almost any configuration, including borehole or surface configurations, and with centrifugal or positive displacement pumps. Surface pumps work well for dams, tanks, creeks, and ponds as long as the pump can be located under 6 metres above the water level. Borehole or submersible pumps can perform very effectively with solar panels as long as the system is correctly planned.

In less sunny areas there may be a benefit in installing a passive (non-motorized) or active (motorized) tracker that will shift the PV panel to gain the most energy as the day progresses. Generators or batteries can also be integrated into the system as a backup for cooler days.

Of course, the reliability and performance of your solar pump depend on the quality of your pump service. To enquire about an onsite or in-house pump service for your solar pumps, contact the Tech Africa team on +263772156504

Good Generator Maintenance

Good generator maintenance is essential for safe, economical, and trouble-free operation for your generator. It will also help with air pollution.

These following maintenance tips apply to normal operating conditions. If you operate your generator under unusual conditions, such as sustained high load or high-temperature operation, or use it in dusty conditions, speak to your local authorized generator dealer on a necessary maintenance schedule to suit.

Fuel Recommendations for Petrol Generators

  • Use regular unleaded fuel with an octane number of 89 or higher.
  • Never use stale or contaminated fuel, and avoid getting dirt or water in the fuel tank.
  • You can use regular unleaded fuel containing no more than 10% ethanol or 5% methanol by volume.

Engine damage or performance problems that result from using a fuel with percentages of ethanol or methanol greater than this are nor covered under warranty from manufactures.

Air Cleaner Service

  • Inspect the air filter, if the air filter is dirty or broken replace it, otherwise a quick clean of the air filter can mean you can re-use it again.

Spark Plug Service

  • To ensure proper engine operation, the spark plug must be properly gapped and free of deposits.
  • You should clean your spark plug every 100 hours and change it every 300 hours.

Note – A loose spark plug can overheat and damage the engine.

Muffler & Spark Arrestor Service

  • Check the muffler & spark arrester for an excess build-up of carbon.
  • Give both the spark arrestor and muffler a good clean to remove traces of carbon deposits.

Are they in good condition? If not, replace them.

Battery Service

If your model generator is an electric start, your generator’s engine charging system charges the battery while the engine is running. However, if the generator is only used periodically, the battery must be charged monthly to maintain the battery service life.

Water Pump Maintenance Tips

In order for water pumps to run correctly, they require customary maintenance. Developing a water pump maintenance checklist will not only cut your expenses but it will guarantee optimal performance. Here are a few tips that can keep your pump functioning efficiently and trim down your everyday expenditure for upkeep or loss in revenue owing to competence problems.

Day by day maintenance

There are a few things you should have on your day by day maintenance checklist to guarantee top performance. First off, constantly double-check to make certain that the speed of the water pump corresponds with the output in horsepower. Also, examine for leakages, fissure or wear and tear. Day by day maintenance can prevent damage and cut general costs radically.

Monthly maintenance

Your monthly maintenance checklist is supposed to include of a few measures to protect against damage or pointless expenses. Your monthly checklist should entail checking and mending seals, oiling bearings based on specifications, confirm that the water pump is raised firmly on the base and change the motor couplings for adept output or transfer.

Yearly maintenance

If you are well-informed about water pumps, normally you can perform the day by day and monthly maintenance personally. Nevertheless, yearly maintenance should at all times be done by a competent professional for multiple reasons. A technician is trained in the field and has the expertise, skill and adeptness. On a yearly basis a technician should examine the water pump to fine-tune, restore or repair the bearings, drive belt or any other faulty part. In addition, a technician needs to carry out a vibration and temperature examination to make certain that the motor is running in peak condition.

Increasing efficiency through pump maintenance

It is imperative that your pump receives steady maintenance to prevent preventable damage and overhead. In addition, you can raise the water pumps competence by a number of various methods like supporting the output with a small booster pump, cutting back bigger pumps that are not necessary and altering the speed of the pump so it is more proficient.

Special Gear for Water Pumps

Water pumps are ever in motion. To notice any abnormal changes in the waters movement pattern a vibration analyzer can be used to make certain the pump is running correctly. Fluid pumps also have sound patterns. Since the patterns cannot be heard by the human ear an ultrasound analyzer is used to establish any issue within the pump or pipes.

It is important to note that prior to performing any maintenance procedures on a pressure switch, turn off the power at the switch. The current needed to run a well pump is potentially lethal.
