LE LAB, the solar pump sizing software

Professional sizing · 59 countries, 154 reference cities · Free to try, no registration

LE LAB is the sizing software developed by SINES. You enter your water need, the depth and your location, and it returns the pump, the solar array and the controller that go together, with production month by month. The PRO version adds the adjustment, the analysis and the full report.

LE LAB PRO month-by-month solar pumping production analysis
See the result, not just a calculationProduction, critical month and climate data are brought together in one readable project view.

Size your installation in a few minutes

No file to download, no account to create. The calculation runs on official manufacturer data and on solar data for 154 reference cities across 59 countries.

What LE LAB gives you

Every sizing returns six results, ready to use in a quotation or a project file:

  • The right pump, selected from the manufacturer catalogues we distribute.
  • The solar array, with the number of modules and the power required.
  • The installation diagram, from the array down to the discharge.
  • Month-by-month production, so you can check the yearly profile.
  • The worst month, the one that actually governs the design.
  • The pump curves, to verify the operating point.

LE LAB PRO for installers, resellers and consulting firms

The free version covers the sizing itself. The PRO version adds what is needed to take a sizing all the way to a finished study: adjustment, analysis and the full report.

  • Size on the worst month and integrate climate conditions.
  • Adjust the solar array and the panel angle, with production recalculated in real time.
  • Assess autonomy with the water reserve, over sixteen years of actual weather data.
  • Master the electrical configuration: string voltage and controller parameters.
  • Generate a complete report, ready to hand to your client.
  • Access your discounted prices and prepare your proforma.
  • Ask the AI about your study and find all the documentation.

How the sizing works

The tool follows the same method as our technical team: the daily water need and the total head define the hydraulic work to be done, the location gives the available solar resource, and the pump is chosen so that the demand is still met during the least favourable month of the year.

Sizing on the worst month, not on the average

An installation sized on an annual average runs short in the dry season. LE LAB identifies the limiting month and bases the selection on it, which is what makes the result usable on site.

From sizing to supply

Once the sizing is done, SINES Export supplies the equipment. We are a worldwide wholesaler for the brands the tool selects from, and every sizing can be turned into a quotation with export pricing and international shipping.
