Solar System for Farm

Single-phase & Three-phase Application Notes

• >Single-phase power (110V/220V) Primarily applied to daily operational facilities on the farm, including farmyard lighting, small-scale irrigation controllers, ventilation fans, breeding temperature control devices, and office daily equipment. It ensures stable power supply for routine management and auxiliary operations.
•  
• >Three-phase power (380V/480V) Specially designed for high-power core equipment in the farm, such as large-scale irrigation pump systems, industrial-scale climate control units, automatic feeding systems, seed processing machinery, and backup energy storage systems. It delivers a balanced and high-capacity power supply to guarantee the continuity, efficiency, and safety of large-scale agricultural or farming operations.

A solar system for farm faces a different load profile from any building: irrigation pumps that run on a schedule, cold rooms that must never lose temperature, and remote boreholes with no grid connection at all. A solar system for farm therefore has to be sized on pump motor surge and on continuous refrigeration load, not on household averages.

Solar irrigation is the highest-return application on most farms. Replacing a diesel pump with a solar-powered one removes both the fuel cost and the daily refuelling task. Our 150kW farm solar system article covers a full layout.

We size a solar system for farm in three parts. First, the pump: flow rate, head and motor size determine inverter surge capacity. Second, refrigeration: a cold room draws continuously and must have storage sized for at least 12 hours. Third, the farmhouse and outbuildings as a baseline.

A 7.5kW borehole pump with 3x start surge needs 22.5kVA of inverter headroom. A cold room drawing 6kW overnight needs 72kWh of usable battery. Where both exist, we specify a combined system rather than two separate ones, as in our 100kW off-grid power plant.

Every solar system for farm from Mars Solar includes PV modules, ground or roof mounting, pump controllers or hybrid inverters, LiFePO4 storage, cable, MC4 connectors and protection. Off-grid and hybrid configurations are both supported.

Storage uses rack-mounted modules for serviceability even in dusty environments, as shown on our rack mounted energy storage battery page.

Mars Solar exports agricultural solar systems directly, so a solar system for farm carries no distributor markup. Systems are certified to CE, RoHS, TUV and ISO standards with a 10-year battery warranty and 5-year inverter warranty.

Solar irrigation is one of the highest-return rural investments available. The UN Food and Agriculture Organization's energy programme reports that solar pumping removes fuel cost entirely and pays back in two to four seasons - the same outcome a solar system for farm delivers.
