Have you ever thought about installing solar panels for your well pump? If you have an isolated or rural location where electricity is not easily or readily available, you could benefit from a solar powered well pump. There are many reasons to install solar panels.
You can pump water anywhere on earth with no external power required!
There’s a problem with pumping water in rural locations. You need to run utility power to the site! For a long time now, wind power and windmills have been used in these secluded locations. Windmills are expensive and they can be very time consuming to maintain. The innovation in solar water pumping is that there is no need for an external power source. The sun provides the solar panels with all of the needed electricity to pump water from hundreds of feet underground.
Solar well pumps are now more efficient and powerful.
These systems are high power, low maintenance, and efficient commercial products. They are made of stainless steel and feature brushless DC motors. Stainless steel is used for the pump housing and pumping device to ensure appropriate sanitation and a long life while submerged in water. The stainless steel resists corrosion when suspended in water for years, which is much better than aluminum pump housings. Stainless steel housing are also hygienic and they won’t pollute water sources. Furthermore, pumping devices made of stainless steel will minimize wear from sand and other particles, while lifting water from deep underground.
Brushless DC motors are the most efficient DC motors on the market. The one main benefit is not requiring removal from the well to change the brushes, like other DC motors. Brushless DC motors with maximum power point tracking (MPPT) controllers are more efficient than brushed motors.
The systems are low cost and readily available!
Old solar power systems had high price tags attached, almost tens of thousands of dollars. Advances made in technology have made low cost systems possible and readily available. One major advance making this possible are solar cells and panels. Solar cell manufacturing has progressed to the point where it can be sold cheaply, so it is very affordable.
No more ongoing operating costs!
After the initial system cost, there are no ongoing operating costs. Normal wells burn money every time they turn on to pump water. This is not the case for solar well pumps since they get their power from the sun.
Every single day the sun is shining, so you earn free money from the sun! What better deal exists? The sun shines down, water is pumped up from deep underground and that’s saving you from overpriced utility charges.
Systems are flexible and can be upgraded over time.
The parts that make up solar power well pump systems are very flexible. They can be swapped out and upgraded as needed. If increased performance is needed for overcast, low light conditions, extra solar panels can be added. If more water is needed on a daily basis, batteries and extra panels can be added, and water can be pumped during the night. If more volume is needed, the pump can easily be replaced to a higher power model offering higher flow.
Solar well pumps are simple to maintain.
There are very few mechanical components. Solar panels are highly reliable and they do not require any maintenance, besides the quick wash every year or two. Brushless motors do not have brushes and therefore require no maintenance. The pumping mechanisms are very dependable and are easy to replace in the field. A system should be able to pump tens of thousands of gallons without any maintenance.
Extremely cheap to maintain!
There are two items in solar well pump systems which may need occasional maintenance, but are very low cost. Every year to two, the solar panels should be given a good scrub with soap and water to ensure the best performance. Less often, about every 5 years, it is good to replace the pumping devices which can worsen over time and reduce pumping performance. The benefit is that they can be replaced in the field.
