How this estimate is calculated
Solar Pump Sizing Calculator · calculation version 0.9.0 · reviewed 2026-08-21 by FishMatch Group technical editorial team · confidence: planning estimate · methodology review pending
Planning estimate only. Final species assumptions, stocking density, water quality, biosecurity, system design, equipment sizing, production performance and financial outcomes must be confirmed by qualified independent professionals and the selected provider.
Purpose
Solar-direct or hybrid pumps need a PV array sized to deliver the daily volume against total dynamic head (TDH). This tool converts flow × head into required kWh/day and PV kWp using pump and system efficiency.
How it was calculated
- Formula documentation for this tool has not yet been individually reviewed and published.
Where each value comes from
- Daily water volume
- Buyer input
- Total dynamic head
- Buyer input
- Pump efficiency
- Buyer input
- Daily irradiance
- Buyer input
- System losses
- Buyer input
Limitations
- This tool has not yet passed the documented-methodology review. Treat every output as an unverified planning estimate.
- Add a 15–25% margin for cloudy weeks and pump wear.
- For 24/7 pumping add battery storage — see the Battery Storage calculator.
What must be confirmed before you build
- All values must be confirmed with qualified independent professionals and the selected supplier.

Next step
Review every value above, correct anything that does not match your site, then transfer the reviewed figures into a structured RFQ. Nothing is sent to any supplier until you approve it. Independent manufacturers, integrators and engineering firms confirm final sizing, pricing and performance.
