Solar-powered pumping and irrigation equipment, sized against real pump curves and duty cycles, not a rough acreage estimate.

Source solar water pumping systems sized to pump curve and duty cycle. Off-grid and grid-tied irrigation equipment sourcing for agrivoltaic sites.
Panel and controller sizing here starts from the pump's actual flow and head requirements rather than a flat per-acre estimate, which is what keeps a system from underperforming on the exact days water is needed most.
Standalone off-grid systems need a charge controller and often a small battery buffer, while grid-tied irrigation pairs differently with a farm's existing service. Both paths are covered separately here.
Pump controllers are compared on how they handle a motor's starting current and duty cycle, not just their rated output.
Sizing accounts for the highest-demand days of the season, not an average that leaves a system short when it matters.
Pump and controller compatibility gets checked before installation instead of after a motor trips the system offline.
A solar irrigation system is sized against the pump's actual head, flow, and daily duty cycle, not a rough acreage estimate, so the array and controller can meet peak demand during the hours the pump needs to run. A grid-tied pump draws steady utility power on demand, while a solar system must generate enough energy within the irradiance window to move the required water volume. Matching the array to the pump curve avoids undersizing that leaves fields short during peak season.
Yes, many solar pumping systems run fully off-grid, driving the pump directly from the array through a dedicated controller during daylight, often into a storage tank rather than a battery. Whether off-grid works depends on the pump's duty cycle and how much buffering the water storage provides. Sunhub sources both off-grid and grid-tied configurations based on which the site actually calls for.
Solar irrigation pumps typically pair with a pump-specific controller or variable frequency drive built for the pump's duty cycle, with MPPT input to track the array and protections for dry-running and over- and under-voltage. The controller must match the pump's motor type and power rating, since a mismatch is a common cause of nuisance faults and premature wear. Sunhub sizes the controller to the pump rather than shipping a generic unit.
