How Do Swimming Pool Solar Panels Work

Now you know why you require these panels to heat your swimming pool. You might wonder how the panels work for a swimming pool.

Solar thermal system for your swimming pools is easy and efficient. Essentially, a solar panel system consists of four parts:

• The Collector: This is the main component of the solar heating systems. The collector is mostly installed on the roof of your property, and it contains reinforced glass pipes that capture the radiation emitted by the sun that is transferred into heat.
• A Pump: The pump circulates the heat transfer fluid between the panels and the cylinders. It is generally powered by a photovoltaic cell.
• A Valve: Valves control the flow of liquid in the pipes. Different valves come in a panel to control the solar heating system’s pressure, temperature, and fluid flow.
• A Filter: Filter removes debris from your pool water. In addition, the liquid that flows through the filter is diverted to the solar heating system.

Essentially, a solar swimming pool heating system works through solar energy. It raises your swimming pool’s water temperatures by 5° Celsius by harnessing the sun’s energy.

Your pool remains heated longer with a solar heater to enjoy your swimming pool for a long time. The mechanism is quite simple.

First, the water flows via the filter, which eliminates debris. The pump would lead the water into the collectors that help heat it efficiently. This warmed water is sent back into your swimming pool. Flow control valves exist that divert the water to the collector.

A panel near your swimming pool that works using the sun’s heat helps you warm your swimming pools without much maintenance.

Types Of Swimming Pool Solar Panel

You can choose several solar thermal panels based on the type of collector and panel. Below are some of them:

Unglazed Solar Collector

Price-wise, an unglazed collector is the least expensive and simplest option. The collector surface does not have a glass flat plate layer; they are made of rubber or black plastic.

Unglazed collectors consist of an absorber that can withstand ultraviolet light.

These collectors may prove less efficient in cold climates. However, their cost-efficiency has been proven as they transfer heat well and their prices are lower.

Glazed Solar Collector

Glazed panel prices are higher, and they prove costly. They are made of aluminium, iron-tempered glass, and copper.

Their efficiency is higher in colder climates, and you may continue using them all year round to heat your swimming pools with the sun’s energy. Plus, they are used for heating fluids for domestic purposes, too.

Individual Tube Panel

Few companies manufacture the tube panel. Their cost is on the higher end. However, they prove more advantageous.

They handle higher wind speeds with fewer roof or site penetrations. Installing them is easier and requires only clamps on the header’s length. The individual tube panel system is more durable and leak-free and boosts the efficiency of heating your pool.

Solid Solar Panel With Straps

They are essentially monolithic polymer panels requiring more roof or site penetrations. Plus, they cover a larger area as you’ll use 3-5 straps to make it sit correctly on your roof or site.

The price of this type of panel is the cheapest, and their performance is enhanced when the sunlight is hitting directly on the panel. So, it might perform better in the hottest part of the year.

Generally, these pool heater systems require more maintenance than the other pool solar thermal systems.

Tips To Use Solar Panels Efficiently

While using solar thermal systems to heat your pool, you might want to consider the following conditions and tips to boost its efficiency and environmental friendliness:

• Importantly, use pool covers for preserving heat and lowering evaporation. They are fundamental to the solar heating system
• Ensure your panels are south-facing and are not in the shaded part of your house
• Ensure the installation size is at least 30 to 60 per cent of the area of the pool or more.
• Try getting Dura+ heat pumps that can help you save 83% of the cost of operating your solar thermal system
• Make sure you place your pool solar heating system in your house near the pool.
• Ensure you buy a pool solar thermal system that is already efficient. While the initial cost of buying such a system will be high, it will be worth it in the long run as your energy prices will drop considerably.
• Contact an expert who will take their time, knows the solar thermal system, understands what is required, and has years of experience installing it.
• While the systems require little maintenance, they require regular cleaning as dust and dirt accumulating on the surface can reduce efficiency.
• If you use energy management software, you’ll be able to monitor the output of your solar panel and ensure its ideal efficiency.
