Proyecto de energía solar y almacenamiento de 200 kW para un molino de arroz en Abuja, Nigeria

Project Background — this solar system for rice mill project replaced diesel for the bulk of the milling load.

A rice milling factory located in a remote area of Abuja, Nigeria, had long been affected by unstable public grid power. Due to frequent power outages, the factory could operate for less than two hours per day, severely limiting overall production capacity. At the same time, local electricity prices increased by more than 30% within the year, causing energy costs to rise continuously and making traditional grid power and diesel generator solutions unsustainable in the long term.

Desafíos de los clientes

• -- Suministro eléctrico inestable con frecuentes cortes de luz.
•  
• -- El continuo aumento de los precios de la electricidad hace que los costes operativos sean impredecibles.
•  
• --Alto consumo de combustible y elevados costes de mantenimiento de los generadores diésel
•  
• -- Equipos de producción que requieren un suministro eléctrico muy estable.

Solución

MARS SOLAR designed and delivered a customized 200kW solar power and energy storage integrated system for the customer:

• -- Los módulos fotovoltaicos de alta eficiencia de LONGi mejoran el rendimiento general de la generación de energía.
•  
• -- Sistema inversor IGBT de la marca Fuji para garantizar una tensión y potencia de salida estables.
•  
• -- Sistema inteligente de almacenamiento de energía con batería de litio y BMS avanzado, adecuado para un funcionamiento prolongado con cargas elevadas.
•  
• - -Diseño estructural de grado industrial combinado con conmutación automática ATS para lograr un suministro de energía ininterrumpido durante 24 horas

Resultados del proyecto

• 1. Se logró un suministro de energía estable las 24 horas del día, lo que garantiza una producción continua.
•  
• 2. Sustitución completa de los generadores diésel, lo que reduce significativamente los costes operativos.
•  
• 3. Período estimado de recuperación de la inversión de aproximadamente 2 años.
•  
• 4. Vida útil del sistema de más de 25 años.

A solar system for rice mill operation combines two demanding loads: heavy motor-driven milling equipment with large start surges, and continuous lighting, drying and storage. Both have to be designed for, and they pull the specification in different directions.

That combination is what makes a solar system for rice mill project worth studying: the load is unforgiving, the cost of failure is high, and the economics have to work on measured results rather than on a vendor's estimate.

Cada solar system for rice mill project starts with 7 to 14 days of logged consumption. Base load is separated from peak load, generation is sized on daytime consumption, and storage is sized on the overnight block. Motor-driven equipment adds a surge requirement that catches out quotations based on average draw alone.

Where a site must never lose supply, we size for autonomy rather than for bill savings — a different calculation that usually means a larger bank and a bidirectional inverter with automatic transfer.

Mars Solar realiza y exporta solar system for rice mill packages factory-direct: PV modules, mounting, hybrid or bidirectional inverters, LiFePO4 storage, protection, cabling and remote monitoring, all tested together before shipment and certified to CE, RoHS, TUV and ISO.

See comparable hardware on our batería de almacenamiento de energía montada en bastidor page, and the Programa de energía del Banco Mundial for how reliable supply affects output in these markets.

Budgeting a solar system for rice mill duty starts with the load log, not the roof area. Milling motors draw three to six times their running current on start-up, so the inverter is sized for the surge and the battery is sized for the overlap when two motors start together. Once that is fixed, the rest of the solar system for rice mill layout follows: array on the warehouse roof or a ground-mount beside it, storage close to the mill floor to keep DC runs short, and a generator that stays connected but stops carrying the base load. In Abuja the payback came less from the tariff than from the diesel that stopped being bought at all.
