Solar Pumping Systems
Power your irrigation and water supply with the sun — zero fuel, zero electricity bill.

Solar pumping systems use photovoltaic panels to power water pumps for irrigation, livestock watering, domestic supply, and fish pond management — eliminating diesel or electricity costs entirely. They are ideal for farms and remote properties in Eastern Visayas where fuel prices and grid unreliability make traditional pumping expensive.
A solar pumping system consists of a solar array, a solar pump controller (also called a VFD or MPPT pump drive), and a water pump (submersible, surface, or centrifugal). The controller converts solar DC power to variable-frequency AC to drive the pump motor, adjusting pump speed in real time based on available sunlight. No batteries are required — the pump simply runs whenever there is sufficient sun, storing energy in the form of water in a tank or pond. For overnight or cloudy-day operation, a small battery bank or grid backup can be added. These systems are promoted by the FAO and World Bank as a cost-effective solution for smallholder farmers in developing nations.
How It Works
Solar Panel Array
Panels are sized to the pump motor's power rating. A 1 kW submersible pump typically needs 1.5–2 kWp of panels to account for losses and operate under partial cloud.
MPPT Pump Controller
The controller tracks the maximum power point of the solar array and converts it to the right voltage and frequency for the pump motor. It also provides dry-run protection and fault monitoring.
Water Pumping
The pump lifts water from a well, river, or pond. Submersible pumps are used for deep wells (10–100 m+); surface pumps for shallow sources. Flow rate depends on pump size and solar availability.
Storage Tank Buffering
Water is pumped during daylight into an elevated tank or reservoir, providing gravity-fed supply throughout the day and night without batteries.
Key Benefits
Zero Fuel Cost
Diesel pump operators in Eastern Visayas spend ₱500–₱2,000 per day on fuel. Solar pumping eliminates this cost entirely — the sun is free.
Eco-Friendly Irrigation
No emissions, no noise, no diesel spills. Solar pumps protect the surrounding soil and water table from fuel contamination.
Low Maintenance
Solar pump systems have fewer moving parts than diesel engines. With no combustion components, service intervals are minimal — typically an annual inspection.
Works Anywhere
No grid connection required. Ideal for farms, highlands, and coastal areas in Leyte, Samar, and surrounding islands where grid access is limited or unreliable.
Supports Food Security
Reliable, affordable irrigation enables year-round cropping instead of rain-fed farming — directly increasing harvest yields and farm income.
Fast Payback
At ₱1,000/day in diesel savings, a ₱150,000 solar pump system pays back in under 6 months for continuous-use agricultural applications.
