This article mainly focuses on the Thai market in 2025. Taking the product solar water pump as an example, the ultimate goal is to tell you how to choose solar panels. Other countries that want to know can also refer to it, especially in those regions with abundant sunlight and relatively scarce power resources. Whether you are a wholesaler, distributor, supplier, or someone planning to enter the photovoltaic industry, if you want to learn about solar panel water pumps or know how to choose solar panels, you can read this article.
A water pump is a device that transfers liquid from one place to another through mechanical energy. It can increase the energy of the liquid and is mainly used for transporting various liquids such as water, oil, acids, bases, and more. The working principle of a water pump is to drive the rotor through an electric motor or other power sources, creating a pressure difference, thereby pushing the liquid to flow.
Solar-powered water pumps are devices used for extracting and moving water. Unlike traditional pumps that rely on fossil fuels or grid electricity, these pumps utilize solar radiation through photovoltaic panels to convert solar radiation into electrical energy. Solar water pumps come in various types, such as photovoltaic solar water pumps, solar water heaters, and domestic water pumps. Solar water pumps are generally submersible or surface-mounted and have multiple applications, ranging from irrigation of crop areas, drinking water systems to livestock water supply installations.
Compared with traditional water pumps (mainly driven by grid power or diesel engines), the core advantages of solar water pumps lie in four aspects: long-term economic efficiency, environmental friendliness, adaptability to various scenarios, and ease of maintenance. Especially in scenarios without grid coverage, long-term use, and high environmental protection requirements, these advantages are more prominent.
Comparison Dimension | Solar Water Pumps (Advantage Performance) | Traditional Water Pumps (Mains-Powered/Diesel-Powered, Corresponding Situation) |
Long-term Economy | Operating costs are nearly zero (no electricity/fuel fees).The initial investment can be recovered in 5-8 years. The subsequent annual average cost was merely for cleaning expenses. | Mains-powered pumps and Diesel-powered pumps: with high long-term costs. |
Environmental Friendliness | Zero carbon emissions and zero exhaust gas (no CO/NOₓ); operating noise is less than 50 dB (similar to normal conversation), with no environmental pollution. | Mains-powered pumps: Indirect carbon emissions exist when relying on thermal power; Diesel-powered pumps: Directly emit exhaust gas, with noise over 80 dB (close to traffic noise), causing environmental pollution. |
Installation Flexibility | No reliance on power grids, requiring only an average of ≥4 hours of daily sunlight; can be deployed in mountainous areas/islands/grasslands without the need for power line installation | Mains-powered pumps: Need to be close to power grids, with extremely high power line installation costs in remote areas; Diesel-powered pumps: Require frequent fuel transportation, which is inconvenient in mountainous/desert areas. |
Maintenance Cost | Simple maintenance (only cleaning solar panels), no easily worn parts; annual maintenance cost is low; failure rate of core components (solar panels/water pumps) is less than 1%. | Mains-powered pumps: Require inspection and repair of motors/bearings; Diesel-powered pumps: Require oil/filter/spark plug replacement. |
Equipment Lifespan | Solar panels have a lifespan of 25-30 years, and DC brushless water pumps have a lifespan of 10-15 years; the whole unit can operate stably for over 15 years. | Mains-powered pumps: AC motors have a lifespan of 8-10 years, and the whole unit has a lifespan of about 10 years; Diesel-powered pumps: Internal combustion engines have a lifespan of 5-8 years, and the whole unit has a lifespan of 6-8 years. |
Energy Dependence | Relies on renewable solar energy, no need to purchase external energy; can cope with short-term cloudy/rainy days when equipped with batteries, featuring strong energy independence. | Mains-powered pumps: Rely on power grids, and stop operating when there is a power outage; Diesel-powered pumps: Rely on fossil fuels, and cannot operate when fuel is in short supply, with limited energy supply. |
The data in the above table is for reference only.
•Solar power generation components (energy core): Solar panels (absorbing sunlight to convert into direct current electricity, power source), optional battery storage (for storing electricity to cope with low light / cloudy days);
•Control and adjustment components (stability guarantee): Solar controller (adjusting voltage / current, preventing overload damage to equipment), if using an AC pump, a inverter (converting direct current electricity to alternating current) is required;
•Pump body (execution core): Pump body with motor (such as submersible pump, centrifugal pump), driven by electrical energy to rotate the impeller for water pumping;
•Basic auxiliary parts: Water supply pipeline (for delivering water), solar panel support frame (for fixing and adjusting the angle to maximize sunlight collection).
According to the "In-depth Research and Analysis Report on the Thai Water Pump Market from 2025 to 2029" released by a Industry Research Center, the Thai government has recognized the significance of agricultural development for the economy and people's livelihood. Therefore, it has proposed relevant plans to provide support. For instance, in 2024, the Thai government proposed to expand the coverage area of farmland irrigation to 40 million bhat (1 bhat is approximately 1,600 square meters). Under this background, the demand for water pumps is expected to be released as the scale of agricultural production in Thailand expands.
The Investment Promotion Board of Thailand (BOI) offers tax exemptions and other preferential policies to the machinery manufacturing industry, encouraging foreign enterprises to conduct local production. This initiative has attracted international brands such as German Wil Pump to set up factories in Thailand, and has also nurtured a number of local component manufacturers.

The climate in Thailand is highly unique: it is consistently hot throughout the year (with temperatures reaching up to 40℃), there are concentrated rainfalls, and the ultraviolet rays are intense. This poses significant challenges for solar-powered water pump systems. Many times, various problems arise, but it is not necessarily the pump itself that is at fault; rather, it is the solar panels that are the issue.
The research shows that during cloudy days or after rainy seasons when there is haze, the water output of the pump will weaken or even stop. This is not a problem with the pump itself - it's a problem with the solar panels. Ordinary solar panels typically have a conversion rate of only 15%-18% under low-light conditions, which is simply not enough to provide sufficient power for the pump.
Ocean Solar's double-sided mono solar panels can still maintain a conversion rate of over 20% even under low light conditions. For the most commonly used 1-horsepower irrigation pumps used by Thai rice and vegetable growers, this means that they can basically provide a stable water supply from dawn to dusk.
The humidity in Thailand usually remains between 70% and 90%. Coupled with sudden heavy rain, it is very likely to corrode the frames of cheap panels and damage the internal circuits. We have seen many uncertified panels develop leakage and short-circuit problems within just 3-4 years, and replacing them would cost even more money each time.
•Anti-corrosion aluminum frame (tested to be usable in humid conditions in Thailand for over 10 years)
•Ultraviolet-resistant backsheet (prevents cracking caused by strong light)
•Excellent waterproofing (easily handles heavy rain)
Many users only consider the price when choosing solar panels, but they fail to take into account the power requirements of the water pump. For instance, a 300-watt solar panel might not be able to power a 2-horsepower water pump (resulting in inefficiency), while a 400-watt solar panel paired with a 0.5-horsepower water pump is simply a waste.
You just need to tell us the brand, power and purpose of the water pump (for example, "used for irrigation for 6 hours every day"), and we can provide you with perfect solar panel selection suggestions.
Rather than choosing high-quality solar panels, it is more about selecting a reliable solar partner, as they will help you develop a customized solution.Here is the list of the top ten global solar module suppliers in 2025 for your reference.
