A brief look at New Zealand’s solar market
Unlike most economies worldwide, New Zealand boasts of colossal renewable energy penetration. Currently, renewables account for 90% of the nation’s total energy consumption. Despite the high degree of renewable energy utilization, solar generation in New Zealand is still at its lowest.
The most recent solar capacity statistics reveal that New Zealand’s grid-connected solar energy stands at 159 Megawatts. This figure is pretty low, considering that the country’s solar potential is 11 Gigawatts. Nevertheless, things are looking up for New Zealand’s solar market due to new solar-centered initiatives.
In December 2020, the government of New Zealand launched a Green Investment finance facility worth US $69 million. Based on this development, forecast studies reveal that solar penetration could reach 9.3 % by 2050, up from 0.2% in 2020. Essentially, New Zealand could have an installed capacity of 300 Megawatts in 2025 and I.1 Gigawatts by 2030. Logically, many projects will have to be implemented to achieve these targets. This will generate opportunities for solar installers and professionals in New Zealand’s solar market.
New Zealand’s solar equipment supply capability
New Zealand has several solar equipment suppliers focusing on different equipment categories, including solar panels, solar water pumps, and charge controllers. Nevertheless, there is a big possibility that you will not find what you need, especially when dealing with large-scale projects. Still, there is a simple solution in such a scenario.

Solar Water Pump
Solar water pump definition
A solar water pump is a mechanical pump powered by electricity generated using photovoltaic panels. It is popularly referred to as a solar water pumping system because it requires several key components to work. The critical constituents of a functional water pump include;
- A solar panel array
- A mechanical DC water pump
- Photovoltaic cables
- A fuse box
- A solar charger control
You can employ a solar water pump in various applications, including crop irrigation and drinking water supply. Currently, it is the most suitable option for all your pumping needs because it has several benefits. It is essentially more efficient to operate and less costly to maintain than traditional fossil fuel-powered pumps. More importantly, it is environmentally friendly primarily because it runs on renewable solar energy. How exactly does it work?
The solar water pump’s working principle
When most of us hear of a solar water pump, we assume it is pretty challenging to use. I can confidently tell you that its usage is pretty straightforward once you install all the necessary components. Figure 1 below offers an outline of the main things you need to have in place for your solar water pump to work efficiently;

The solar array absorbs solar energy and converts it into electric energy. The solar water pump’s inverter converts the DC electric current output generated by the photovoltaic system into AC. The AC electric current powers the pump and propels water from the source to the intended destination.
It is also crucial to note that the inverters regulate the electricity output frequency and voltage instantaneously. These regulatory actions correspond to variations in sunlight intensity. In simple terms, the system switches to supplementary energy automatically when sunlight intensity weakens. Is this not enough to convince you that a solar water pumping system is worth its investment?
Classifications of solar water pumps
There are several classifications of solar water pumps that you can choose from depending on your specific needs. The main varieties of solar water pumps include;
- The submersible solar water pump
This type of pump is ideal for deep water sources such as wells. It can lift up to 650 feet of water provided the sunlight energy can generate sufficient electricity to power the pump. Consequently, it is advisable to pump and store water when the sun’s intensity is at its best.
- The surface solar water pump
This pumping system is suitable for shallow water sources, including streams, storage tanks, and ponds. They can comfortably lift water with a depth of not more than 20 feet. If you intend to draw water beyond this depth, it would be best to settle for submersible pumps.
