Solar Water Pumping Solutions

Most solar water pumping systems are assembled from separate components: a DC pump, an inverter, solar panels and mounting.

The Problem

Why This Is Specified as a Solution

Most solar water pumping systems are assembled from separate components: a DC pump, an inverter, solar panels and mounting. Buyers often find that the pump does not match the inverter's voltage range, the panels do not deliver enough power at peak sun, or the system fails to start when the grid is unavailable. WeBright Solar ships a complete, matched system with the pump, inverter, panels, mounting and control logic already configured to work together, so the system operates from the first day instead of requiring on-site adjustments.

Process

Every Stage and What Goes Wrong at It

The amber line is the failure this stage usually produces. The line under it is what we do instead.

1

Enquiry and Water Requirement Review

The pumping depth, flow rate and daily volume are not defined at the start, leading to undersized or oversized systems.

We ask for the well depth, required flow rate, daily water volume and peak sun hours before proposing a configuration.

2

System Sizing

The pump capacity and inverter rating are chosen independently, causing mismatched power delivery.

The solar array, inverter capacity and pump power are sized together on a single voltage platform to ensure full compatibility.

3

Component Selection

DC pumps are selected without checking voltage compatibility with the inverter or panel output.

We confirm that the pump's maximum DC voltage, inlet/outlet diameter and well adapter size match the inverter and panel configuration.

4

Mounting and Installation Planning

The pump mounting bracket is not suited to the wellhead or ground condition.

Mounting is designed to the actual wellhead or ground structure and confirmed with the buyer before shipment.

5

Inverter and Control Logic Setup

The inverter does not switch between solar and AC input correctly, or fails to start under low irradiance.

The inverter is pre-programmed for automatic solar priority or AC complementary operation and tested before packing.

6

Assembly and Testing

A pump fails to start or the inverter shows error codes during commissioning.

The pump and inverter are tested together under load, and the control logic is verified before crating.

7

Packing

Pump, inverter and panels arrive damaged or split across multiple shipments.

The pump, inverter, solar panels and mounting structure are packed in wooden boxes for export loading.

8

Shipping and Documents

The buyer must coordinate multiple suppliers for delivery and customs clearance.

OEM, design, sourcing and shipment are handled from one place, so the buyer receives one shipment and one set of export documents.

Who It Is For

Buyers This Suits

  • Farmers and irrigation contractors in off-grid or unstable-grid regions
  • Water supply project managers for villages, schools and livestock facilities
  • EPC contractors delivering turnkey solar pumping solutions
  • Importers and wholesalers who resell complete solar pumping kits
Outcomes

What You End Up With

  • A matched system with pump, inverter, panels and mounting already configured for the well depth and flow rate
  • A single voltage platform that the inverter, panels and pump agree on
  • A mounting structure designed to the actual wellhead or ground condition
  • One shipment with all components, including the pump, inverter, panels, mounting and control wiring

FAQ

Solar Water Pumping Solutions Questions

Can you quote a system from my well depth and water requirement?

Yes. Send the well depth, required flow rate, daily water volume and peak sun hours, and we will return a configuration with pump, inverter and panel size.

Do you supply systems for both shallow and deep wells?

Yes. Systems are available for wells up to 125mm well diameter and with pumping depths matched to the pump's rated head.

Can the system work with AC grid backup?

Yes. The inverter supports AC complementary input and can switch automatically between solar and grid power.

What pump types do you support?

We support permanent magnet DC centrifugal pumps with inlet/outlet diameters of 1 inch or 2 inches and well adapter sizes up to 125mm.

How is a complete system packed?

The pump, inverter, solar panels and mounting structure are packed in wooden boxes for export loading.
