Size, adjust and document
your solar pumping projects
LE LAB Pro gives you greater control over each project: refine the sizing, configure the solar array, generate reports and find the technical documentation from your account.
A tool designed to support you, from study to job site
From the technical study to the client presentation, LE LAB Pro brings together the tools you need to size, analyse and document your installations.
More control over every sizing
LE LAB Pro complements the free sizing: a finer analysis, a mastered configuration, projects ready to present.
For constant-pressure installations, the irrigation schedule can also be adjusted to analyse how pumping is shared between solar power and the backup source.
Size on the worst month PRO
Adapt the sizing to the most demanding periods of the year.
Switch from the average month to the worst month to check the available production and keep a margin.
Integrate climate conditions PRO
Display rainfall or average temperatures directly on the production chart.
Climate and water production can be read at a glance, season by season.
Adjust your solar array PRO
Change the number of panels and immediately see the impact on production.
Select the panel from the library, from your personal list or enter its characteristics manually.
LE LAB only offers configurations compatible with the system's modelled electrical characteristics. The sizing matches the available equipment and the project constraints.
Adjust the panel angle PRO
Switch from the optimal angle to the actual angle of your structure: production recalculates immediately, month by month.
The gap is shown as a percentage of the optimum, over the full year or over your pumping season.
Assess autonomy with the water reserve PRO
Your water reserve is simulated day by day over sixteen years of PVGIS solar history: fully covered days, incomplete days, worst episode.
No reserve yet? LE LAB recommends a volume, and shows the one that would cover every day of the sixteen years simulated.
Master the electrical configuration PRO
Access the complete configuration of the photovoltaic array: number of panels per string, parallel branches, operating voltages and controller limits.
This information makes it easier to verify and prepare a configuration that is consistent with the selected equipment.
Generate your report PRO
Your sizing becomes a complete report, structured for presentation and the project file.
- A cover page in your name, with the contents and the project data
- The essentials: pump, controller, solar array and the key figures
- The installation diagram with its legend
- Production month by month against the need, then hour by hour on a typical day
- Hydraulics: selected pipe, water velocity, head losses and pressure
- Autonomy and water reserve, simulated over sixteen years of PVGIS weather history
- Manufacturer curves with the operating point and the string voltages
- Technical appendix: electrical configuration, cables and sizes, operating conditions
After review, it can be shared with the client or filed in the project folder.
Ask the AI about your study PRO
Ask a question about a figure or a term in the study on screen: the answer usually arrives in a few seconds, in your language.
The assistant answers from your study, the official technical documentation of the selected pump and the way LE LAB works. If the information is not within this scope, it says so.
Find all the documentation PRO
Manuals, datasheets and equipment brochures are available from your Pro account.
Everything is in one place, with language and format clearly identified.
The LE LAB PRO manual covers entering a study, reading the result and the technical functions.
LE LAB Connect: the sizing API
Integrate the LE LAB sizing engine into your configurator, portal or business application.
