Attapeu Province, Laos

Farmers in Attapeu Province, Laos, have long faced the problem of insufficient power supply, often leading to irrigation interruptions and a surge in the risk of reduced yields for local banana growers. To solve this problem, Solartech, in collaboration with local partners, tailored "solar + grid power" dual-drive irrigation solution, achieving a stable 24-hour water supply (rotational irrigation).

✅ Hybrid Power System: supports both solar and grid power input and solar prority
✅ Intelligent Operation and Maintenance: Supports remote monitoring, real-time viewing of power generation, water pump status, and other data.
✅ Compatible with Existing Equipment: Solartech PK-CA solar pumping control cabinet directly matches 37kW three-phase water pump and its supporting sprinkler system.

💰 Economic Benefits: Significantly reduced electricity costs, lowering farm operating expenses.
🌱 Increased Productivity: Stable water supply ensures banana irrigation needs are met, increasing yields.
♻️ Ecological Contribution: Reduced carbon emissions, promoting the green transformation of local agriculture.
🌟 Scalability: Successful cases attract attention from surrounding farm owners, promoting the application of renewable energy in agricultural irrigation.

❓ Q1：What is a "Solar + Grid" dual-drive system and how does it operate?
✅ A：The system supports simultaneous inputs from both solar PV panels and the local grid power, operating based on a "solar-priority" mechanism:
Daytime (Ample Sunlight): The system prioritizes solar energy to power the water pump, maximizing the utilization of free clean energy and significantly cutting down electricity bills.
Nighttime or Overcast Days (Insufficient Sunlight): The system switches to grid power or allows the grid to supplement the deficit power, serving as a "double insurance" to ensure irrigation never stops.

❓ Q2：What core equipment from Solartech was used in this project? Did the farm need to replace its existing pumps?
✅ A：The project utilized the Solartech PK-CA series solar pumping control cabinet.
This control cabinet features excellent compatibility and does not require replacing the farm's existing pumps. In this specific case, it directly matched and drove the farm's existing 37kW three-phase water pump and its supporting sprinkler irrigation system, successfully upgrading the legacy infrastructure into a smart system while minimizing the client's initial investment.

❓ Q3：What benefits can this system bring to farms?
✅ A：It can significantly reduce electricity costs, ensure banana yield through stable water supply, reduce carbon emissions, and has good scalability, driving the green irrigation transformation of surrounding farms.
