Solar Irrigation Pumps
Pump water for your fields without diesel or grid dependence.
Irrigation pumping is one of the largest recurring costs for Bangladeshi farmers, particularly where diesel pumps are used for boro rice cultivation. Solar irrigation pumps eliminate the ongoing fuel cost and reduce exposure to diesel price volatility, running instead on daylight availability that aligns naturally with irrigation demand during the dry season.
CZ Engineering has designed installations following the model supported by IDCOL's solar irrigation programme, which has financed solar pump installations for farmer cooperatives and individual growers across the country. We size the pump and panel array to match the water table depth, field area, and crop water requirement of each site, and coordinate with local agricultural extension offices where a permit or NOC is required for groundwater extraction.
For cooperative or multi-farmer sites, we can also configure metered water distribution so that costs are shared fairly among users drawing from a single solar pump.
How it works
- 1
Water and land assessment
We assess the water source, static water level, and command area to determine pump capacity and panel array size.
- 2
Permitting coordination
Where required, we assist with groundwater extraction permits and local agricultural office approvals.
- 3
Pump and array installation
The solar array, pump controller, and submersible or surface pump are installed and tested against actual field flow rates.
- 4
Handover and seasonal support
Farmers receive operating guidance ahead of each irrigation season, with maintenance support available through planting cycles.
Financing available
Solar irrigation pumps are eligible for financing support modelled on IDCOL's solar irrigation refinancing scheme, often channelled through farmer cooperatives or partner microfinance institutions to reduce upfront cost for growers.
