From solar tubewell to automated tubewell
A solar tubewell already cuts fuel cost dramatically compared with a diesel pump. But most run manually — someone switches them on in the morning and off later, and hopes the timing and the water level are right. Automation closes that gap: the system decides when to run, protects itself, and reports back, so the pump becomes something you manage rather than babysit.
What automation adds
A tubewell automation system typically adds four things:
- Scheduling: run the pump automatically during the hours of strongest sun, and stop it when generation drops.
- Dry-run protection: sense when the borehole or tank has run dry and stop the motor before it is damaged.
- Level control: start and stop based on a tank filling or emptying, so you never overflow or run dry.
- Remote monitoring and control: see status and switch the pump on or off from a phone, from anywhere.
| Feature | What it does | Why it matters |
|---|---|---|
| Scheduling | Runs the pump in peak-sun hours; stops as generation drops | Uses your own solar directly — worth more under net billing |
| Dry-run protection | Stops the motor when the borehole or tank runs dry | Prevents the most common cause of a burnt-out motor |
| Level control | Starts and stops on tank fill / empty | No overflow, no running dry |
| Remote monitoring & control | Start, stop, and check status from your phone | No daily trips to the field |
Why timing to sunlight matters
A pump is one of the largest and most flexible loads on a farm — which makes it perfect for shifting into peak sunlight. Running it when your panels are producing most means you use your own solar directly, rather than drawing from elsewhere. Under Pakistan’s 2026 net-billing rules, where self-consumed energy is worth much more than exported energy, timing a big load like a pump to the sun is a direct saving, not just a convenience.
Protecting the motor — and your time
The most expensive failure on a tubewell is a burnt-out motor, often from running dry. Automatic dry-run and level protection removes the main cause of that failure, because the system stops the pump the moment conditions are unsafe — faster and more reliably than a person can. And remote control removes the daily trips to the field just to switch a pump on or off, which on a large or remote holding adds up quickly.
How it fits with the rest
Tubewell automation is one part of WattEY’s automation family — the Tubewell Automation System — alongside smart switching, metering, and energy management for other loads. If you already have a solar tubewell, automation is added to it; you do not rebuild the system. The result is irrigation that runs on its own schedule, protects itself, and answers to your phone.
