Technical studies & system sizing
SINES Export does not stop at supplying equipment. Every project we quote can start with a genuine technical study: our team sizes the system from your real data, then returns the complete bill of materials with wholesale pricing. Solar pumping is our strongest competence; storage, off-grid and hybrid systems follow the same discipline.
Your data in, a complete system out
The study is free and comes with your wholesale quote: pump or inverter model, solar array size, controller, cables, protections and accessories, with the manufacturer datasheets. Nothing left to guesswork.
What we size
Solar pumping
Boreholes, wells, rivers and ponds: pump, array and controls sized from head, daily demand and location. Grundfos, LORENTZ, ABB.
Irrigation systems
Drip, sprinkler and pivot stations: pressure and flow from your field layout, with filtration and hybrid power schemes.
Storage & off-grid
Lithium storage (BESS), inverter/chargers and solar inverters sized on the actual load profile and autonomy target.
Village water supply
From borehole to tap: pump, tank, level controls and distribution for communities, with NGO-grade documentation.
How it works
1. Your data
Borehole report, field layout or load profile, plus the location. A few photos help; a nameplate photo is enough for retrofits.
2. Our sizing
Our team selects the duty point on the manufacturer curves, corrects for your local irradiation and checks water quality limits.
3. Your quote
Complete bill of materials, datasheets and wholesale quote. Order when ready: we export worldwide with reliable logistics partners.
The engineering behind it
A serious sizing is a chain of checks, not a catalogue lookup. Total dynamic head including friction losses, daily demand in m³ per day, irradiation of the worst working month, duty point placed on the real manufacturer curves, and the water itself: sand content, pH and chlorides decide the pump variant. Our sizing guide explains each step in plain language, with a worked example and the reference diagrams.
Beyond pumping: storage, off-grid and hybrid
The same method applies to energy systems. For off-grid, backup and hybrid applications we size lithium storage, inverter/chargers and solar inverters around the measured or estimated load profile: daily consumption, peak power, autonomy target and growth margin. Component compatibility is validated across brands, so the battery, the inverter and the monitoring actually talk to each other on site.
Dedicated support for NGOs and project owners
Water supply, irrigation and rural electrification projects often run in remote areas, on public or donor funding, with documentation requirements to match. We support NGOs and project owners from initial scoping to commissioning: technical study and sizing, equipment selection, export logistics, and the manufacturer documentation your funding partners expect. The equipment we recommend is the equipment we stock and warrant.
What to send us
- Pumping: borehole depth and diameter, static water level, drawdown and tested yield, pipe run to the tank, tank elevation, daily water demand, location.
- Irrigation: crop and field area, irrigation method or sprinkler package, water source, elevation profile, location.
- Storage and off-grid: appliance list or load profile, desired autonomy, existing equipment nameplates, location.
- Retrofits: photos of the existing pump or inverter nameplate and of the installation.

Frequently asked questions
Is the study really free, with no obligation?
Yes. The study comes with a wholesale quote for the sized equipment; ordering it is your decision. We size accurately because an undersized or oversized system always comes back to the supplier's door.
I do not have a borehole report. Can you still size?
Yes, from partial data with stated assumptions, refined later against the drilling results. For new boreholes we tell you exactly which measurements to request from the driller: static level, drawdown and tested yield.
Which brands do you size and supply?
The brands we distribute: Grundfos and LORENTZ for pumping, ABB for pump inverters, Victron, Pylontech, SMA, Studer and others for storage and off-grid. The study recommends what fits your duty point, not a house favourite.
