How to install solar panels for swimming pool?


The solar heater is the main element used for the extraction of alternative thermal energy by the heater. The principle of operation of the solar heater is very simple. Water heats up when it passes through the grids and tubes of small diameter solar heater. These tubes and grids are solar traps. They consume solar energy.

Proper installation of the solar heater is very important. It will achieve the maximum amount of heat generation. The installation of solar collectors made professionally will allow the solar system to serve for at least a quarter of a century.

You should consider in detail how to install pool solar panels on your tile roof before proceeding with installation. You need to determine the desired roof area for the installation of panels. The installation location will expand if the power of the panels increases. An area of 2 square meters is necessary to heat 200 liters of water in the pool. You will need 4 square meters if the volume of your pool is 400 liters.

The design of fasteners may vary depending on the type of roof. The scheme of fasteners for cattle and flat roofs will be radically different. The mounting support of the solar collector is mount parallel to the roof, above the roofing coating or with embedding in the roof with a pitched roof surface. Mounting on a flat roof is more complicated from an engineering point of view. Contact a qualified installer for the calculation if you are doing this for the first time.

A solar heating system will work as productively as possible if you know how to install solar pool heating panels correctly. The correct angle of inclination of the solar panels can increase the annual performance. The tilt angle must be calculate individually for different types of heaters. Vacuum collectors with «heat pipe» technology have a minimum allowable angle of 27 degrees. Flat systems do not have such limitations, unless it is a Drain back system.

The solar collector should be turn in the most effective direction. It may be south, west, east, southwest, and southeast. Direction depends on your region of residence.

The amount of heat produced depends on the amount of solar radiation that hits the surface of the panel. We must consider the possible shading of buildings, trees, chimneys throughout the day during installation. Significant shading can lead to heat loss and reduce the economic effect of using a solar system.

The distance between the panels must be consider when building large objects on a flat roof. Shading of devices with each other may occur. Installing a solar panel for above ground pool requires additional theoretical training. It will allow carrying out the installation correctly and using the system for many years.

Pool solar panel installation instructions

A detailed algorithm for installing a solar panel to heat the pool will help you install quickly and efficiently.

1. Remove the heater from the box and warm it with the sun (30 min.) Do not lay the heater on the grass due to the possibility of fire. Brackets and piping require one foot of free space around the solar device. Collectors can be install on either side of the slot if the roof has slots 3 “in diameter. The brackets of the upper assembly are located in each groove along the entire length of the heater. The heater should be tilt to the plugs for pumping water in case of preparation for winter operation.

2.Install the bottom brackets directly below the bottom of each top bracket.

3. Drill 1/8 “holes for all brackets. The square-head screw must be long so that it can touch the inside of the roof under the roof tiles. Fill the holes with plenty of sealant. The surface around the holes should also be cover with reinforcing material. Insert the brackets into the roof and fill the head with sealant.

4. Check all connections. Make sure they are tight and firmly installed.

5. Expand the valve so that water flows through the solar device.

6. Start the pump and check for leaks. You will see bubbles from the air in the pool. It is explain by the fact that the solar installation is blow with air. The bubbles will disappear in a few minutes.

Solar have a simple scheme, but do not be deceive by this factor. We must be serious about choosing a pipeline. Water temperature in the system may be high. The pipeline must withstand such a load. The main part of the solar system is under the influence of natural precipitation when installing the solar heater on the roof. You must adhere to the perfect corrosion protection and maximize the support. This will avoid changing the geometric shape of the structure due to strong wind gusts.

Many pool owners prefer to install a chassis heater. Your solar collector will heat better if it is remove from the earth in a cold period. Black plastic or a platform under the heater can help. Pay attention to the figure below where the design and the table with materials are indicate.

This information is useful if the heater is install on a chassis with a slope. The chassis with a slope should be turn in the direction of the sun and fully consecrate by the rays. It is better to install it in such a way that children cannot access the device.

Solar pool heater installation requires a clear sequence of actions. Your system will last for many years if you can install it correctly. A solar heater on the roof requires more knowledge and time to install. You can place your solar panels in the yard if there is enough space. Use the installation instructions and follow all recommendations. It will help you install the solar heater as quickly and efficiently as possible.


Any solar pool heating system consists of three main elements:

– solar collector;

– pump filter;

– control valve.

The mechanism of action is very simple. The heated water is direct through the filter to the heat exchanger of the solar system from the pool. The filter is use to prevent debris from entering the solar heaters. A more powerful pump for the filtration system may be need in some cases.

The most efficient of the modern systems include an automatic bypass valve. The filtration system of the pool is adjust to work when solar lighting is most intense. Water is heat inside the heat exchanger due to the influence of coolant on it, which circulates in a closed system of connected solar heaters. The heated water returns to the pool. Water does not run through the solar heater when it cools down.

The solar heater is most often located on the roof. Placement should be flat or have a slight slope. The return pipe must be higher than the water supply pipe. All pipes should gradually rise relative to each other. Therefore, the air will be force out of them. You need to pay attention to this information to understand how solar heating for pools work.

Solar swimming pool heating systems do not require special care and maintenance. They need only the usual cleaning of filters and preparation for the cold season. Water from the system should be drain before the onset of cold weather. Such measures will allow you to understand how to use solar panels to heat the pool for as long as possible.

It is very difficult to buy a solar heater without accurate calculation. Each pool owner must initially solve the problem and calculate everything. You can buy a heater only after that.

Consider a specific example. There is a pool with a volume of 32 m3 and an area of 20 m2. It is use in the period from May to September. The owner uses a special polyethylene coating at night for protection for 12 hours. The task of the heater is to maintain the temperature at around 24 degrees. Its slope is 45 degrees. Water consumption is 280 liters per day on average.

Each solar heater has a usable area. For example, 14 m2 is the entire area. Absorbent owns 6 m2 of the total area. There is a ratio of 0.4-0.6 m2 of absorbent per 1 m2 of the area of the pool itself in this situation. You need to take the volume of the pool and divide by this ratio. You will get the number of heaters to be place on the surface as a result. You need to understand how solar panels heat the pool to choose the right heater.

Most pool owners are interested in how to hook up solar panel to pool pump on their own.We provide a clear algorithm for connectinga solar heater.

  1. You need to ensure the outflow of water from the panels into the pool. The presence of a three-way valve will create optimal conditions for the circulation of water. This device should be install after the filter and pump. The best option would be a valve that has automatic control. It will allow it to be connect remotely. In addition, you can set the timer to turn on the valve.
  2. The next step is to install the pipe, which is T-shaped. It should be connect to a three-way valve. The connection should be in line with the edge of your pool. Such a circulation scheme will allow directing the flow of water from the solar panels to the valve. The stream will go straight to the pool further. The winter season involves the release of the system from water.You need to buy collapsible valves to avoid problems with the freezing system.
  3. The overflow pipe should preferably have a diameter of 3 to 5 centimeters. You must choose a pipe of the same size. It will circulate water to the panels and back. The plastic construction of the pipes should be securely fast if the solar panels are located on the roof of the building. Eaves or walls of the building are the best place for fastening. Pipes should prefer be placed underground. It will free the yard from obstacles and avoid mechanical damage to the system.

Important! The fitting is universal for each pipe. This type of connection allows you to remove the panel from the roof in the cold season without difficulty.

  1. Solar panels for pool heating may have different dimensions. The most convenient and versatile size is 5 * 50 centimeters.

Note! Initial installation is best do with two panels. You will be able to assess their power and rate of heating water in the pool.

Other panels can be install a little later. The number of solar panels should be approximately the same as the area of your pool. Pump power plays an important role in calculating heating power. The pump should have a power of 186 W if you place the panels at a height of more than one floor. Such a pump will be required if the supports for the heating system are longer than 2.5 meters.

  1. You can place the pool heater on the ground to simplify installation. Stainless steel bolts are most suitable for installation. The distance between the rafters on the roof must be measure in advance. Bolts should be place at a distance that is slightly larger than the size of the solar panels. This distance is approximately 60 centimeters.
  2. Roofing mastic will be need during installation. It should be apply to the surface of the bolts to prevent leakage. Special crossbar should close the bolts from the top. An aluminum crossbar with holes on the sides is best suited. Steel gaskets and nuts should be use during installation. They allow you to remove the solar panels quickly and easily.

Note! Special permission must be obtain for installing a rooftop heating system from a local cooperative. The construction plan will allow this permission.

  1. The solar panels should be interconnect after mounting the structure on the roof. The next step in the installation is connecting them to choke fittings. The incoming and outgoing horses of the pipe should be connect to the corresponding inlet. Air may stagnate in the pipes if the system is not properly connected. The outgoing edge of the pipe will be direct upwards if the installation of solar panels is carry out at an angle.
  2. You must turn on the pump after connecting the pipes. The valve should be open after this. The design efficiency is determine by the strength of the water flow in the system. The water temperature in the panels will be 3-4 degrees higher than in the pool. The pool will be heat throughout the day.

A noticeable rise in water temperature will be note after a week if your pool is small. A small and medium-sized pool requires at least three solar panels to heat water in the summer. Two additional panels allow you to extend the swimming season.

Solar heaters are not choosy to work with, but you must calculate the right amount of devices to install before installing them. It is worth paying attention to the presence of free space between them. The main principle of placement is to get sunlight on the device for 4-5 hours. Solar heating will show itself from the best side in such a situation and will be able to maintain the temperature at a level of 25-30 degrees. You can extend the swimming season for 1-2 months if you are in sufficiently sunny regions.
