Start / Water and irrigation

Pumping, energy and cost

Pump engine, solar energy for pumping, reservoir for irrigation water and irrigation cost per bag.

Pump engine: power and engine replacement

Calculate the motor power of the irrigation pump from the flow rate and total head, and compare the cost of rewinding or replacing the motor based on energy use and payback period.

Motor power for irrigation pump and cost of rewinding or replacing

Solar energy for irrigation

Size the photovoltaic capacity and number of panels for an irrigation pump, based on pump power, pumping hours, and the site's irradiation.

Panels and area for the irrigation pump

Irrigation reservoir

Calculate the water volume per irrigation interval, the total reservoir volume including reserve and losses, the base dimensions and the filling time by the pump.

Volume, dimensions and filling time

Irrigation cost per bag

Calculate the irrigation energy cost per millimetre and per hectare, the total cycle cost and the cost per bag, from total head, efficiency, tariff and depth.
