What is a solar pool heater & how it works

Solar pool heaters use thermal energy from sunlight to warm the pool water. A solar pool heater comes with a solar panel, pump, and filter. 

Solar panels will be mounted on the rooftop like the traditional solar system. In this system, solar panels are used to get energy from the sun. 

The pool heater is connected to the panel to heat your pool water. Solar pool heaters work entirely on solar power and don’t require electricity.

Besides, many solar pool heaters come with a flow control valve and an automated sensor. These components will detect the water temperature and provide the desired temperature by understanding through the sensor.

The flow control valve derives the water through a solar collector, and it will enter the pool after getting heated.

Calculate solar pool heater cost

Before talking about solar pool heater cost, let us clarify the truth is that: powering your current pool heater with solar panels is costly. Suppose you are looking for a heating solution for your outdoor pool. We suggest you look at the best option to heat the outdoor pool.

Solar pool heater cost depends on the size of the pool and the wattage of the heater. It is not appropriate to tell you the exact amount without knowing the measurement and capacity of the heater. 

It will be easier to understand if we do the calculation based on an average solar pool heater.

An average 12 feet solar pool heater costs $3000 to $7000, including solar panels, heater, filter system, pump, and installation costs to power your existing pool heater with solar energy. It will cost you only $300 if you use the solar heating kit.

What are the costs for a solar pool heater?

We have told you the average costs for an average solar pool heater in the above section. If we concentrate on several parts of the installation and estimate the cost for each section, you will get a perfect calculation of the costs.

Let’s explore!

Cost for panels

The solar panel cost is a massive expense for a solar pool heater. A 12×12 feet pool heater consumes 15000 watts to operate. You have to install a 1500 watt solar panel to run this heater. If you purchase 5x300watt solar panels, it will cost you $1500 to $3000 depending on the brand and quality.

If you already have a solar system for your setup, you can directly connect your heater to the system. The heater’s energy consumption will be fine with the family solar system.

Cost for installation

The maintenance cost is not too much for a solar swimming pool heater. The solar panels are weather-resistant in this system and can perform even on a rainy day.

Sometimes, you have to clean it for excessive snowfall.

The maintenance costs for a solar pool heating system are around $300-$1000 annually. In general, it is about $30-$100 depends on what you need to fix OR maintain.

How many solar panels do you need for a solar pool heater?

You can only reveal the answer to this question when you know the wattage of the pool heater and the efficiency of your selected solar panel. 

The efficiency of solar panels is measured in watts, and you have to understand the kWh to clarify the number of solar panels.

Similarly, the number of solar panels depends on the panel’s power.

For example, you have a solar swimming pool heater of 1500 watts, and you will run it for ten hours a day. 

The calculation is that it requires 15000 KWh in total for a day.

Then select the solar panel that you think the best for you. 

If you select 100watt solar panels for the system, you have to purchase 15 solar panels.

On the contrary, if you select 300watt solar panels, you have to take 5 solar panels.

So, the measurement is clear and very easy to understand. But select a model that is perfect for mounting options.

Don’t buy solar panels that will not fit your rooftop.

How many solar panels do you need for a 12ft inground pool? 

A 12ft inground pool heater is ideal for residential pool heating. This device will provide you with warm water consistently in all weather conditions. 

But you need a powerful solar system to run this efficient solar swimming pool heater. Otherwise, you won’t get the expected heat from the device.

As we explained in this article, 12ft solar heaters are the average-sized device for swimming pool heating. It requires 1500watt power. You can buy fifteen 100 watt solar panels or five 300 watt solar panels.

The decision depends on you and the mounting option. Remember, when you select large solar panels, the size will be increased automatically.

Which solar panel type do you need to buy? 100 watts or 300 watts? Or even 1000 watts

Selecting the most efficient solar panels for solar pool swimming pool heating is important. In general, solar pool heaters are used in winter. 

If you don’t select a high-efficient solar panel type, you won’t get the desired heat from the device.

Snow and insufficient sunlight will reduce the energy production rate of the total system.

However, there are three types of solar panels, polycrystalline, monocrystalline, and thin film.

Among them, monocrystalline solar panels have the most efficient solar cells. They come with more than 21 percent of efficiency. 

So, you can purchase monocrystalline solar panels for your solar swimming pool heater.

Then what do you think about the size of the solar panel? You can select the most compatible solar panels size based on the mounting option and rooftop size.

A 100watt solar panel requires a small space, but you have to install multiple solar panels.

On the contrary, if you install 300watt solar panels, you have to purchase fewer solar panels, but the price and size are higher than a 100watt solar panel.

Finally, if you select a 1000watt solar panel, it will be expensive, and your system will shut down in case of any problem. The reason is that it depends on only one solar panel.

Which brand should you buy? 

The brand is a vital issue when thinking about solar panels. If you get solar panels from a renowned and established brand, the system will ensure the productivity and efficiency of the solar panels.

Similarly, top brands have a global supply chain and first-class customer support.

If you ask them to calculate and install solar panels, they will do it professionally. There is no doubt about getting quality service from them.
