Consequently, this study focuses on evaluating the performance, energy efficiency, and economic feasibility of a solar-powered photovoltaic (PV) pumping system for drip irrigation in Kaleo, Upper West Region of Ghana.

How does a solar-powered irrigation system work?

A solar-powered irrigation system uses photovoltaic (PV) panels to convert sunlight into electricity, which then powers a water pump. This pump draws water from a source — such as a well, pond, river, or reservoir — and distributes it through pipes or drip irrigation systems to crops. The main components include:

What is solar water pumping?

When compared to electricity or diesel powered systems, solar water pumping is more cost effective for irrigation and water supply in rural, urban, and remote areas. It also makes an effort to bring to light the challenges that must be overcome in order to develop high-quality, long-lasting solar power technology for future uses.

What is a solar-powered irrigation system (Spis)?

In a solar-powered irrigation systems (SPIS), electricity is generated by solar photovoltaic (PV) panels and used to operate pumps for the abstraction, lifting and/or distribution of irrigation water. SPIS can be applied in a wide range of scales, from individual or community vegetable gardens to large irrigation schemes.

What are the benefits of a solar water tank in Portugal?

Apart from the obvious economic and ecological benefits, Portugal also pay out grants for photovoltaic solar systems. The advantage of using a solar water tank is that it avoids using a conventional pump, which keeps the complexity and costs of a thermosiphon system low.

What is the potential for solar power in Portugal?

The potential for solar power in Portugal is at an all-time high at the moment. Thanks to two successful solar tenders, the Portuguese photovoltaic (PV) market is experiencing a surge in large-scale projects.

Why should you invest in a solar system in Portugal?

Harness natures free power and supply electricity to your whole household or business. Apart from the obvious economic and ecological benefits, Portugal also pay out grants for photovoltaic solar systems.

What is a photovoltaic solar system for self-consumption?

In Portugal with a Photovoltaic Solar System for Self-consumption you can generate your own electricity, becoming energetically autonomous and reducing electricity costs. Beyond the right to produce electricity for self-consumption, you can also store and trade the surplus electricity production.

How do you design a solar water pumping system?
