Factors influencing the cost of a solar powered water heater

Solar water heaters utilize sunlight to heat water through a collector (thermal). Configurations are available at various prices to provide alternatives in multiple latitudes and climate zones. Solar water heating systems are frequently utilized in commercial and residential settings.

This article will outline all you need to know before buying a solar water heater.

1. Type

There are two types of solar heating systems: non-pressurized and pressurized. A pressurized heater requires a specific water pump to power the water through the heater (solar). Water from certain tanks moves by gravity in a non-pressurized heater. The following are the general characteristics of these solar water heaters;

  • Easy Installation

Flat panel installation is far more complex than evacuated solar water heater installation. This is due to the fact that flattened plates have heavier panels that must be securely mounted on a specific roof. Evacuated solar water heaters, on the other hand, are lighter and simpler to assemble.

  • The efficiency of Solar Water Heaters

Evacuated solar heater tubes use less energy than flat-plate water heaters (solar). This is attributable to the detachment of these evacuated tubes by a given vacuum in order to minimize heat loss via convection and conduction. The efficiency being discussed is the partial output and is dependent on the absorber unit (active).

  • The ratio for Absorber Area

Flat plate collectors have a larger absorber area than evacuated tube collectors. As a result, even though evacuated and flat collectors are the same size, their absorbing energy ratios differ. The absorber area ratio is an essential factor to consider when determining the solar water heater price in Kenya.

2. Brand

This refers to the solar heater’s model or manufacturer. It is a distinguishing factor because it relates to the materials, shape, expertise, and quality. All of these aspects of a brand, including reputation, play an essential role in determining the solar heater’s value.

This is due to customer feedback on these aspects of the product. It is a deciding factor for a buyer in terms of getting a good return on their investment.

3. Capacity and size

According to market trends, the price of a solar water heater is frequently directly proportional to its size and capacity. It is commonly assumed that the heater’s power and efficiency are directly proportional to its capacity and, thus, value. In general, the larger the absorption surface area and storage tank capacity, the greater the conversion of solar to heat energy and heating capacity.


Solar water heater prices are heavily influenced by various factors, including type, size/capacity, and brand. The best price is determined not by the amount charged but by the value you derive from the product at the set price. By researching the fundamental aspects of the heater you want to buy in relation to your utility needs, you will likely get the best value for the best price.

In addition, it is essential to choose one that will help you save money on your home’s energy bills while providing services for a more extended period. Additionally, consult with some solar water heater providers to better understand your options and establish a budget.
