Northwest Department and Artibonite Department of Haiti

In Haiti, over 80% of the rural population lacks access to safe drinking water, the power grid coverage rate is extremely low, and agricultural irrigation has long relied on expensive diesel pumping. To address the dual challenge of "water scarcity and power shortage," three solar pumping systems funded by Welthungerhilfe (WHH) Germany and supported by the European Union were officially commissioned in May 2025 in the Northwest Department and Artibonite Department of Haiti.

The project fully adopts Solartech one-stop turnkey solar pumping complete solutions, with all core equipment and auxiliary materials integrated and supplied by Solartech to ensure optimal system matching and long-term stable operation. Each system delivers an impressive 1,000 cubic meters of water per day, simultaneously meeting the needs of large-scale farmland irrigation and centralized domestic water supply for villages.

🔹 Core Configuration: PB37KH-G3 smart solar pumping inverter + SPB10-150-30 high-efficiency submersible pump + 54kW monocrystalline PV array, complete with C-channel steel mounting structures, combiner boxes, specialized cables, and a full-system lightning protection solution
🔹 Operation Mode: Solar PV direct-drive as primary power source, with intelligent diesel generator backup for 24/7 uninterrupted water supply
🔹 System Design: 43 meters total dynamic head, following the "solar priority, hybrid energy" philosophy to minimize post-project fuel and O&M costs, precisely aligning with WHH's core requirements for low-cost, long-term sustainable operation

Technical Advantages

✅ High-Efficiency MPPT Algorithm: Patented dynamic VI multi-criteria tracking technology, efficiency up to 99%, stable operation under fluctuating sunlight conditions

✅ Full Turnkey Capability: From solar pumping inverter, pumps, PV arrays, mounting structures, combiner boxes, cables to lightning protection — all jointly developed, manufactured, and delivered by Solartech, eliminating compatibility risks from multi-brand mixing and significantly reducing post-installation maintenance complexity

👨‍👩‍👧‍👦 Community Well-being: Provides stable, safe drinking water for over 10,000 villagers, eliminating the health risks associated with surface water contamination and waterborne diseases
🌾 Agricultural Productivity: Ensures dry-season irrigation, reduces farmers' diesel costs, and supports Haiti's efforts to improve food self-sufficiency
🌱 Green Model: Zero-carbon solar model serves as a replicable, standardized benchmark for similar projects across the Caribbean region

❓ Q1: Why did WHH choose Solartech as the preferred turnkey solar pumping solution provider for its Haiti project?
✅ A: International aid projects impose stringent requirements on equipment suppliers. Solartech has consistently earned recognition from WHH and other international organizations based on the following core competencies:
✅ One-Stop Turnkey Solutions: Unlike single-equipment vendors, Solartech provides end-to-end integrated delivery — from inverters, pumps, PV arrays to mounting structures, combiner boxes, cables, and lightning protection. All core equipment is independently developed and uniformly spec-matched by Solartech, eliminating compatibility risks from multi-brand mixing and greatly reducing O&M difficulty in remote areas.
✅ Extreme Environment Adaptability: The PB series solar pumping inverters feature IP65 protection rating, allowing outdoor installation without additional pump houses, perfectly suited for Haiti's hot and humid climate.
✅ Smart Hybrid Energy Control: Standard PV/diesel dual-input design automatically starts the generator during cloudy days or at night, ensuring 24/7 uninterrupted water supply — precisely matching international aid projects' core need for long-term sustainable operation.
✅ Global Project Experience: With successful solar pumping project deliveries in over 130 countries and regions worldwide, Solartech brings extensive experience in international aid and community development projects, with products fully compliant with international certification standards.

❓ Q2: Given Haiti's weak power grid and high diesel costs, how does the solar pumping system ensure stable water supply for both irrigation and domestic use?
✅ A: This is precisely where Solartech's engineering advantages shine:
✅ Completely Grid-Independent: The system operates on pure solar power, unaffected by local power outages — ideal for off-grid and electricity-scarce rural areas.
✅ "Solar Priority, Hybrid Energy" Design: Runs on 100% solar power during sunny days with zero electricity costs; automatically switches to diesel generator backup during extended cloudy periods or at night, ensuring 24/7 continuous water supply while balancing economy and reliability.
✅ Smart MPPT Algorithm: Even under cloudy or fluctuating light conditions, the system maintains stable pumping with 99% tracking efficiency, maximizing solar energy utilization.
✅ Comprehensive System Protection: Supports soft-start to eliminate water hammer effects, with full protection against over-voltage, over-current, phase loss, and dry-run conditions — fully automatic operation with no manual intervention required.
