It works like any other pump set with the only difference being the solar energy used instead of non-renewable energy for its operation. When sunlight falls on the solar panels it produces direct current (DC) which then feeds the motor to pump out the water. However, in the case where the motor requires an alternating current (AC), the DC produced by solar panels is converted to AC using an inverter.
Frequently Ask Questions
Yes. Without any issue, a 3” solar pump can be used in a larger diameter well casing. The larger well acts as a reservoir for longer pumping durations without depleting or drawing down the well.
Our standard controller does have the option to use a Grid or Generator but for such conditions, we can provide another controller that has the option to connect with a Grid but we need to know in advance before supplying the product.
You can increase the power to the controller, however, you will need to make sure that the voltage input to the controller remains within the limits. The additional power will not increase the peak flow rate; however, the additional power will allow the pump to run more efficiently during the early mornings, late afternoons as well as cloudy days.
The Solar pumps we use work on low voltage so extending the cable too far will affect the performance and thicker cables need to be used to counter the volt drop. Depending on the size and voltage of the pump. It's best to increase the cable between the controller and pump and keep the cables between the controller and panels as short as possible to get the best efficiency out of the pump.
Head is the maximum vertical height above the pump that the water needs to be pushed and this also includes the losses over the distance that needs to be pumped.
Yes, with our controllers come standard 3000 rpm and can be reduced as per required performance.
The easiest way to determine this is to add 30% on top of the pump wattage for minimum requirements I.e. a 500w pump requires a minimum of 650w.
The system needs very minimal maintenance which includes cleaning the panels regularly. Cleaning maintains the efficiency of the panel without which the panel’s surface gets reduced exposure to irradiation from the dust and dirt on it.
The controllers are not limited to wattage. You will need to make sure that the solar panels are connected correctly to avoid exceeding the voltage rating of the controller.
