Solar irrigation in Mexico

Can solar pumps be used for irrigation in Mexico?

Large-scale solar pump systems for irrigation in Mexico are few, as grid power is reliable and heavily subsidized (tariff 9CU: 0.033 USD/kWh and tariff 9N: 0.016 USD/KWh), making it more cost-effective to run electricity pumps. In more remote, rural areas and for decentralized, small-scale farms, solar pumps may provide a viable alternative.

What is solar-powered irrigation?

Solar-powered irrigation is a cross-cutting topic that requires not only expertise in solar energy (by planners and suppliers), but also in water management/irrigation and agriculture (by technical government staff, agricultural extension workers and farmers).

How can solar-powered irrigation systems improve access to water?

In line with this, FAO and GIZ have also developed a Toolbox on Solar-Powered irrigation Systems for advisors. The report also stresses the importance of water resources assessments and planning to avoid increasing pressures on water resources. By reducing costs, SPIS can improve people’s access to water.

Is solar irradiation overestimated in Mexico?

Specific production of PV plants in Mexico is less than the projected production. Solar irradiation is overestimated in comparison to other factors. Only a slight increase in productivity with increasing irradiation is observed. Solar inverter providers optionally offer plant operators online access to their installed photovoltaic (PV) systems.

Are solar powered irrigation systems a viable option for small farmers?

As investment costs for solar powered irrigation systems (SPIS) are coming down and subsidy schemes for SPIS are being rolled out, solar technologies are becoming a viable option for both large and small-scale farmers. SPIS provide reliable and affordable energy, potentially reducing energy costs for irrigation.

How much solar irradiation does Mexico produce?

PV systems in Mexico generate in the range between 90 and 125 kWh kW −1 month −1. Specific production of PV plants in Mexico is less than the projected production. Solar irradiation is overestimated in comparison to other factors. Only a slight increase in productivity with increasing irradiation is observed.
