Well, borehole, river or pool: answer a few questions and the configurator picks the pump, the panels and the pipe.
Find your pump in 1 minute
Free, no sign-up: pump, panels and pipe, ready to order.
The whole range at a glance
Each curve is a pump: the higher it goes, the further it pushes; the further right, the more it delivers. Plot your point to see which ones fit.
Three examples calculated live
The configurator redoes these calculations on every visit, with today’s catalogue and prices.
Live calculation- Well: water at 5 m
- 250 m² on drip
- 1 m³ per day
- 125 mm borehole, 40 m
- Trough 60 m away
- 1.2 m³ per day, all year
- 10 × 4 m
- Pump room next to it

Understand your choice, in pictures
For those who want to know why the configurator suggests a given pump.
Surface, submersible or pool pump?
It all depends on how deep the water is.
Set on the ground, it sucks water from a river, a tank or a shallow well.
Surface pumps →
Lowered into the well or borehole, it pushes water up to 115 m high.
Submersible pumps →
100% solar, or hybrid to filter in the evening too.
Pool pumps →The height to overcome (TDH)
Four heights add up. Example: a drip-irrigated vegetable garden fed from a well.
Rated flow ≠ real flow
The higher the water must go, the less the pump delivers. The configurator reads each pump’s curve at your height.
How much water per day?
Start from your daily need, not from the biggest pump.
The sun sets the daily volume
Peak sun hours per day, month by month (PVGIS, well-oriented panels).
The pipe matters as much as the pump
Head lost in 100 m of PE pipe at 6 m³/h:
The configurator picks the diameter for you (water at 1.2 m/s at most) and warns you if your pipe is holding the pump back.
How many solar panels?
Three figures to read on the label on the back of the panel.
Pool: the whole pool filtered in 4 to 6 h
Flow is measured at the filter, not on the pump label.

Frequently asked questions
Does a solar pump work without a battery?
Yes. Our pumps run directly: the panels power the controller, which runs the pump as long as there is sunlight. To have water in the evening, it is simpler and cheaper to store water in a tank than electricity in a battery.
What happens on cloudy days?
The pump runs more slowly and delivers less water. That is why the configurator shows the volume obtained month by month, based on the real sunshine in your area, and flags the months when it falls below your needs.
Can I use a surface pump on a 12-metre well?
No. A surface pump cannot draw water from deeper than 7 to 8 m, however powerful. Beyond that you need a solar submersible pump lowered into the well.
Do I have to buy the panels from Flocea?
No, panels are not supplied. You can buy them from any seller: the configurator tells you which figures to check on the label (power, Vmp, Voc, current) and can check panels you already own.
What is the difference between maximum flow and real flow?
Maximum flow is measured with no height to overcome. As soon as the water has to be lifted, the flow drops: a pump rated at 6 m³/h may deliver only 3 m³/h at 40 m. The configurator reads the flow on the curve, at your real head and with your pipe.
Is the configurator’s result guaranteed?
It is a serious pre-sizing based on the pumps’ performance curves and European sunshine data, but it does not replace an on-site check. A button lets you have your set-up reviewed free of charge by a Flocea adviser before you buy.
How do I calculate the total dynamic head (TDH)?
Add the water depth below the pump, the rise to the delivery point, the pressure you need at the end (1 bar = 10 m: about 1 bar for drip, 2 to 3 bar for sprinklers, nothing to fill a tank) and the pipe friction losses. Example: 5 + 2 + 10 + 3 = 20 m. Then choose the pump on the flow read from its curve at that head.
How many solar panels does a pump need?
It depends on the pump: 1 panel of at least 400 Wp for a 24 V 280 W surface pump; 2 panels of 450 to 550 Wp in series for a 48 V 600–750 W submersible pump; 3 panels of 450 to 500 Wp for a 900 W pool pump; 4 panels of about 450 Wp for a 1,200 W 110 V model. Voltage matters as much as power: the configurator checks Vmp, Voc and current.
Which pipe diameter should I choose?
Aim for a water velocity of 1.2 m/s at most. Over 100 m at 6 m³/h, a PE 25 pipe loses 121 m of head, a PE 32 30 m, a PE 40 10 m and a PE 50 barely 3 m. The configurator calculates these losses for your flow and length and recommends the diameter.
How long should the cable of a submersible pump be?
The pump depth plus the distance to the controller, usually 5 m, rounded up to the next ten: a pump lowered to 40 m needs 50 m of cable. Our submersible pumps come with 2 m of cable; you choose 10 to 100 m (4 mm²) when ordering.
