Solar PV modules
Generates the DC power the system runs on. The array is sized around the pump duty and the site, and the modules are confirmed as part of the same selection as the pump and the inverter.

System components
What completes the system.
Selected with the pump.
A solar pumping system is more than a pump and an inverter. These are the parts that carry the water, connect the borehole to the surface and bring the array wiring together — and each one is settled by the installation it goes into.
The parts that complete the system
01 / The parts that complete a system
One job each.
Settled by the installation.
Each part below has one place in a pumping system and one reason to be there. What that part has to be is decided by the installation it goes into.
PV mounting structure
Holds the array at the angle and orientation the site calls for, on the ground or on a frame. It is part of the array design rather than a separate purchase.
- Decided by
- The array design and the ground
PV combiner box
Sits between the array and the inverter. It gathers the array wiring into one point before the power reaches the inverter, so the array is connected in an orderly way instead of every run being taken separately to the inverter.
- Decided by
- The array design
MC4 connectors
Joins the module strings and brings the array wiring to the combiner box. Supplied with the array wiring rather than chosen on its own.
- Decided by
- The array wiring
Solar DC cable
Carries DC power from the array to the inverter along the route it takes. Length and cross-section follow the array layout on the site.
- Decided by
- The array layout and the run
Output filter and reactor
Fitted between the inverter and the pump where the cable run or the motor calls for it. It conditions the inverter output for the pump over the run it is installed in.
- Decided by
- The run and the motor
Submersible pump cable
Connects the pump in the borehole to the inverter at the surface and travels the whole depth with the pump. It is the part that stays permanently under water.
- Decided by
- The depth and the run
HDPE water pipe
Carries the water from the pump to the tank or the point of use, buried along the route or laid above ground. It is the part that has to hold the pressure the pump produces over that distance.
- Decided by
- The route and the water
None of these parts is picked from a list. Part, size and material are confirmed against the selected pump and the site.

Depth, run and water decide the parts.
02 / What decides each part
The installation first.
The part afterwards.
Component selection is an outcome of the system selection, not a separate choice made on its own. These are the points that settle it.
- The array and its mounting follow the pump duty and the site.
- The array wiring and the combiner box follow the array design.
- The cable follows the installation depth and the run from the borehole to the inverter.
- The pipe follows the installation and the water it has to carry.
- The output filter or reactor is fitted where the cable run or the motor calls for one.
- The exact part, size and material are confirmed against the selected pump and the site.
03 / What to send with the inquiry
Send the site.
The parts follow from it.
Component questions are answered from the same details as the pump selection. Send what you have, and we say what is still missing.
- The water source and the duty the pump has to meet
- The borehole diameter and the water levels, where the source is a borehole
- The pipe route — planned, or already in place
- The pump nameplate details, if a pump already exists
- The site location
Parts can be supplied with a matched system or as a supply enquiry of their own. Either way the answer comes back against your installation rather than from a generic list.
The package is put together after the selection, not before it.
04 / Questions we are asked
Component questions.
Direct answers.
Can components be supplied on their own?
Yes. Parts can be supplied with a matched system or as a separate supply enquiry, and the same rule applies either way: the part is confirmed against the pump and the installation it is going into.
Are the components the same for every system?
No. The parts are confirmed against the selected system and the site. A different pump, a different array design or a different installation changes what is supplied with it.
How do I know which cable or pipe to use?
It follows the installation — the depth, the route and the water — and it is confirmed with the pump selection. Send the site details and the answer comes back as part of the configuration.
