Industrial Solar Storage Success Story - Hight Voltage Solar Electric Battery Storage for Factories

In Aden, Yemen, a manufacturing facility has completed a major energy transition. The plant now runs fully on MOTOMA industrial solar storage and has replaced its diesel generators. This project shows that solar power for industry can be reliable, efficient, and cost effective.

Project Overview

The system was designed to support continuous industrial operation without interruptions. Main components include:

• 3 × MOTOMA lithium batteries — 61 kWh each (183 kWh total)
• 3 × MOTOMA Solis inverters — 50 kW each
• 288 × MOTOMA solar panels — 585 W each

How the System Works

The project combines solar generation with battery storage and power conversion to deliver steady power for heavy loads. During the day, solar panels produce electricity. Inverters convert the power for factory equipment. Excess energy charges the lithium batteries. At night or during low sun, batteries supply stored energy to keep production running.

Key Considerations for Industrial Energy Storage

Implementing energy storage for factories requires careful planning. Important factors include:

• Load analysis: Calculate peak and average demand so the system can handle maximum loads without oversizing.
• Battery sizing: Match usable energy (kWh) and discharge power (kW) to operational needs for reliability.
• Temperature management: Industrial batteries must tolerate local climate. High-temperature performance is crucial in regions like Yemen.
• Scalability: Use modular designs to allow future expansion as production grows.
• Inverter selection: Choose inverters that support grid-forming or hybrid operation suitable for industrial machinery.
• Safety and maintenance: Plan for ventilation, fire safety, and periodic maintenance to ensure long-term performance.

Performance and Benefits

Switching from diesel to MOTOMA industrial solar storage delivered immediate and long-term benefits:

• Zero fuel costs: The factory no longer buys diesel, cutting a major operating expense.
• Stable operations: Properly sized batteries and inverters ensure uninterrupted production.
• Lower maintenance: Solar and lithium systems require less frequent servicing than diesel generators.
• Energy independence: On-site generation reduces exposure to fuel supply disruptions and price volatility.
• Environmental impact: Eliminating diesel cuts carbon emissions and improves corporate sustainability credentials.

Design Tips from the Yemen Project

1. Start with accurate data: Use real consumption profiles over several months to size the system correctly.
2. Prioritize battery usable capacity: Consider depth of discharge and cycle life to meet required runtime and longevity.
3. Allow for heat-resistant components: Select batteries and inverters rated for high ambient temperatures.
4. Plan for modular growth: Design the system so additional batteries or panels can be added with minimal disruption.
5. Balance CAPEX and OPEX: Optimize initial investment against long-term fuel and maintenance savings to reach a sensible payback.

Return on Investment

Industrial solar storage projects often show a clear payback when diesel costs, maintenance, and downtime are considered. Typical payback periods vary by location and energy prices, but many industrial projects recover costs within five to seven years. For this factory, eliminating fuel purchases and reducing maintenance drove a rapid ROI while delivering reliable power.
