Solar pump (VFD) bill of materials template
A solar pump system runs a water pump straight from the panels through a variable frequency drive, with no battery and no grid-tied inverter. The table is the default list the app starts from, read from its records when this page is built. It lists the drive panel, modules, structure, cable and earthing.

How a solar pump works
The drive takes direct current from the panels and feeds the motor at a speed that follows the available sunlight. The pump therefore moves more water at noon than in the morning, and stops when the light is too weak. Water is stored in a tank or used directly for irrigation, so no battery is needed.
What is different in this list
Lines found only in this list: VFD Panel. Lines in the other lists but not in this one: On-Grid Inverter, AC/DC Distribution Box, AC Cable, Lightning Arrestor, Off-Grid Inverter/PCU, Battery Bank and Hybrid Inverter.
Quantity is left for you to set on: Solar PV Module and DC Cable.
Quantity is fixed in the template on: VFD Panel (1 Nos), Mounting Structure (1 Set) and Earthing Kit (3 Set). Change these if the project needs a different count.
What decides the sizing
Three things set the size: how high the water must be lifted, how much water is needed in a day, and the rating of the motor. The panel capacity is then chosen to suit the motor and the drive, not the other way round.
The default list names the drive panel and refers to the motor rating, because the same panel cannot serve every pump.
What the default list leaves out
The default list covers the electrical and mounting parts. If you supply the pump set, delivery pipe, foot valve or a tank, add them as separate lines with their own specifications, so the customer can see exactly what is and is not included.
Protection that matters on a farm
Dry running is a common cause of pump damage, so state whether the drive or a separate device protects against it. Mention the earthing and the cable type, because panels in open fields face weather and animals.
Frequently asked questions
Why does a pump list have no inverter or battery?
The drive runs the motor directly, and the water tank acts as the store. Removing both keeps the system simpler and cheaper to maintain.
Does the list include the pump itself?
The default list focuses on the drive, panels, structure, cable and earthing. Add the pump set and pipework as their own lines when you supply them.
Is a pump system eligible for a subsidy?
Pump schemes are separate from the rooftop scheme and differ by state.

Assuming the list includes the pump
The default list covers the drive, panels, structure, cable and earthing. Add the pump set, delivery pipe, foot valve or tank as separate lines when you supply them.
Sizing the panels first
The lift height, the water needed in a day and the motor rating set the size. The panel capacity follows the motor and the drive, not the other way round.
Saying nothing about dry running
State whether the drive or a separate device protects against dry running, because it is a common cause of pump damage.
What to check before you send
- The lift height, the daily water need and the motor rating are known
- The pump set, pipework and tank are listed as their own lines if you supply them
- Dry-running protection, earthing and the cable type are stated
- Any pump subsidy was checked for the customer's state
