In the drought affected communities of southwestern Africa, access to clean water is a matter of survival

Calai and surrounding regions, Angola

☀️💧In the drought‑affected communities of southwestern Africa, access to clean water is a matter of survival. Solartech is proud to support the ADSWAC Project (Adaptation to Drought in South West Africa Communities) —a multi‑stakeholder initiative led by the Government of Angola, the Sahara and Sahel Observatory, the Adaptation Fund, and ADPP/DAPP—with our PB‑G3 Series solar pumping systems in Calai and surrounding regions.

💡Why Solartech PB‑G3?

- 99% MPPT efficiency with patented dynamic VI maximum power point tracking—maximizing every ray of sunlight
- IP65‑rated, -20°C to +60°C operational range—engineered for harsh, off‑grid African environments
- Battery‑free, “water storage instead of battery storage” design—pumping during daylight, storing water in elevated tanks for 24/7 availability, eliminating battery replacement costs
- Fully automatic start/stop & soft‑start protection—minimizing maintenance in remote locations
- Remote monitoring & 8‑year data logging—enabling efficient project management across vast areas

🌾🐂With over 20 years of innovation, Solartech has delivered solar water solutions to 130+ countries, transforming arid land into productive farmland, supporting livestock, and providing clean drinking water where grid electricity is absent.

🌱The ADSWAC project is more than infrastructure—it is about building climate resilience, empowering communities, and fulfilling SDG 6 (Clean Water) and SDG 7 (Affordable Clean Energy).

❓ Q1: In Angola's drought-affected communities with no grid, high temperatures, and dust, how does PB-G3 ensure stable water supply?
✅ A: Through a complete technical solution designed for harsh off-grid environments.
✅ Maximum use of sunlight: MPPT efficiency up to 99%, using patented dynamic maximum power point tracking technology to make the most of every ray of sunlight.
✅ Harsh-environment adaptability: IP65 protection rating and wide operating temperature range from -20°C to +60°C, designed specifically for off-grid areas with no electricity, high temperatures, and dust.
✅ Water storage instead of battery storage: Battery-free design. Water is pumped during the day and stored in elevated water towers, eliminating the need for batteries and significantly reducing O&M costs.
✅ Unattended operation: Fully automatic operation, intelligent soft start, and remote monitoring, adapted to maintenance conditions in remote areas.
✅ Visualized management: 8-year operating data storage and optional wireless communication module, providing management capability for large aid projects.

❓ Q2: What does this system mean for the ADSWAC Project and local communities?
✅ A: It is not only a water supply project, but also resilience-building in response to climate change.
✅ Clean water supply security: Provides a stable water source for drought-affected communities and enhances local climate adaptation capacity.
✅ Lower long-term O&M pressure: Battery-free, fully automatic, and remotely monitored — suitable for long-term operation of aid projects in remote areas.
✅ Replicable and scalable: Solartech's solar water pumping products and technologies have served more than 130 countries and regions worldwide, from desert management to agricultural and livestock water supply, from ecological restoration to rural revitalization.
✅ Responding to global goals: The ADSWAC Project is a practical response to UN Sustainable Development Goal SDG 6 (Clean Water) and SDG 7 (Clean Energy).
