Reduce swimming pool heating costs by installing a solar pool heater. They're cost competitive with both gas and heat pump pool heaters, and they have very low annual operating costs. Actually, solar pool heating is the most cost-effective use of solar energy in many climates.
HOW THEY WORK
Most solar pool heating systems include the following:
Some systems include sensors and an automatic or manual valve to divert water through the collector(s) when the collector temperature is sufficiently greater than the pool temperature. When the collector temperature is similar to the pool temperature, filtered water simply bypasses the collector(s) and is returned to the pool.
Solar pool collectors are made out of different materials. The type you'll need depends on your climate and how you intend to use the collector. If you'll only be using your pool when temperatures are above freezing, then you'll probably only need an unglazed collector system. Unglazed collectors don't include a glass covering (glazing). They are generally made of heavy-duty rubber or plastic treated with an ultraviolet (UV) light inhibitor to extend the life of the panels. Because of their inexpensive parts and simple design, unglazed collectors are usually less expensive than glazed collectors. These unglazed systems can even work for indoor pools in cold climates if the system is designed to drain back to the pool when not in use. Even if you have to shut the system down during cold weather, unglazed collectors may be more cost effective than installing a more expensive glazed collector system.
Example of how a solar collector works.
Glazed collector systems are generally made of copper tubing on an aluminum plate with an iron-tempered glass covering, which increases their cost. In colder weather, glazed collector systems—with heat exchangers and transfer fluids—capture solar heat more efficiently than unglazed systems.
Therefore, they can be used year-round in many climates. Glazed collectors also can be used to heat domestic hot water year-round.
Both glazed and unglazed collector systems should include freeze protection if they'll be used in colder conditions.
SELECTING A SOLAR POOL HEATER
A solar water heater usually costs between $3,000 and $4,000 to buy and install. This provides a payback of between 1.5 and 7 years, depending on your local fuel costs. They also typically last longer than gas and heat pump pool heaters. Your actual cost and payback depend on many factors. Therefore, before you purchase and install a solar pool heating system, you should do the following:
EVALUATING YOUR SITE'S SOLAR RESOURCE
Before you buy and install a solar pool heating system, you first need to consider your site's solar resource. The efficiency and design of a solar pool heater depends on how much of the sun's energy reaches your building site.
Solar pool heating systems use both direct and diffuse solar radiation. Therefore, even if you don't live in a climate that's warm and sunny most of the time -- like the southwestern United States -- your site still might have an adequate solar resource. Basically, if your building site has unshaded areas and generally faces south, it's a good candidate for a solar pool heating system.
Your local solar system supplier or installer can perform a solar site analysis.
SIZING A SOLAR POOL HEATER
Sizing a solar swimming pool heating system involves many factors:
Solar system contractors use worksheets and computer programs to help determine system requirements and collector sizing.
Basically, the surface area of your solar collector should equal 50%–100% of the surface area of your pool. In cooler and cloudier areas, you may need to increase the ratio between the collector area and the pool surface area. Adding collector square footage also lengthens the swimming season.
In any climate, you can usually decrease the required collector area by using a pool cover.
You'll also want a properly sized pool pump for a solar system. If you're replacing a conventional pool heating system with a solar system, you may need a pump larger than your current one or a separate, smaller pump to move the pool's water to and through the collectors.
A typical solar panel lasts for about 25 to 30 years. And during this period, most of the photovoltaic (PV) systems require little to no maintenance. However, the lifespan of your rooftop PV system depends on the technology, panel quality, and installation. Usually, solar arrays lose only 0.5 percent each year when it comes to performance. Even after using them for 25 years, they usually keep operating at an efficiency rate of 90 percent. Read this post to learn more about the durability of PV systems.
Solid Outer Layers
Though most PV systems have fragile conductive plates inside, reputed solar manufacturers design robust outer layers for increased durability. Whether you have opted for a rigid material or tempered glass, the outer layers are extremely resistant to adverse weather, high winds, debris, branches of trees, and hail.
Lifespan of Solar Systems
The durability of solar panels varies from one model to the other. However, purchasing panels from a reputed vendor will ensure that they last for about 25 to 30 years. Although solar panels do not cease to function, they do start to degrade after the specified period. That said, you don’t need to replace a PV system once it crosses the 25-year threshold. You can easily continue using them as long as you save on your electricity bills.
Mono and Polycrystalline Panels are Efficient
Choose mono or polycrystalline panels because the rate of degradation is much lesser than cadmium telluride, amorphous silicon, and copper indium gallium selenide panels. The output loss is only 0.61 and .064 each year pre-and-post installations.
Improving Solar Panel Lifespan
Keep your rooftop safe from physical damage like tree branches blowing in the wind and scratching the panels. Install the solar panels in a safe position away from branches and sheltered from the winds. Clean the panels on a regular basis.
Take care of your solar panels, and they will take care of all your power needs. If you have a PV system that requires maintenance, feel free to consult with our solar technicians. We can help you with the installation of solar panels, solar pool heating system, and other solar products as well.
There’s no denying that the solar energy industry is booming. With nearly 1.4 million solar installations till date, solar energy has made a mark for itself in the country. But renewable energies still make up a small portion of the total electricity production and solar accounts for just 0.9 percent. So, the real question is, how can we improve the efficiency of this clean energy source? Well, a couple of techniques spring to the mind, more about which you can read below:
Improved performance and greater energy generation is something every homeowner wants out of their investment. However, to achieve that, they should be mindful of the above-mentioned points. If you are yet to purchase a solar panel for your home, choose a good system. We can hook you up with some of the most efficient solar products in the market. Contact us here to know more.
If you are planning to install solar panels for your home, one of the first questions that comes to your mind is— Is my house fit for solar? You need to consider several factors including your roof angle, PV system installation, and the amount of direct sunlight received. So, before you set up the panels, it is important to understand whether they are a good fit for your home or not. Here are a few things to help you figure out if you should install rooftop solar panels:
Solar panels work in different weather conditions, from warmer regions such as Florida and California, to rain prone states like Georgia. Technologically-advanced and high-performance PV systems convert direct and subdued sunlight into electrical energy. It means that your rooftop panels operate in cloudy weather as well. Talk to our solar experts to figure out the amount of energy your solar panels will generate. It will help you understand how much you can save on your monthly power bills by switching to solar power.
Your rooftop solar system will produce more energy from the sun provided the panels face southwards. Make sure it is set up on a surface facing the south for maximum efficiency. Solar panels installed on a flat roof should face south. Let Coast to Coast’s installers check the panel installation, tree shading, and roof angle to ascertain whether your home receives enough sunlight to meet your family’s energy requirements.
PV systems work best on roofs made of asphalt shingle, composite, seam metal, or concrete tile. You can even install solar on roofs made of slate tile, wood shake, or mortar with clay or stone-coated steel or composite metal. Collaborate with a solar contractor with experience in setting up panels on these roofing materials. Inquiring about the kind of mounting hardware is also essential.
If you want to learn whether solar makes sense for your home, take a closer look at your roof structure, quality, inclination, and its exposure to the sun. For more information about our solar products, contact us today.
Selling solar hot water or large scale pool heating into municipal facilities has always been a very difficult task. City people have to protect the interests of their taxpayers at all times. They are under tremendous scrutiny and every snake oil salesman out there is trying to dig his claws into municipal coffers. Cities tend to hire engineering companies in order to distance themselves from the sensitive decision making. Domestic solar hot water heating systems use evacuated tubes or boxed and glazed collectors. These small scale systems don't have good economics because they are small scale. The cost of tanks and controls and plumbing and roofing is high compared to the area of collector exposed to the sun and the collector choice is naturally an expensive one because if you're going to all this trouble you'll want something that delivers maximum bang, not maximum bang for the collector buck. When we start looking at larger scale systems like preheating showers for Aquatic Centers we start to see much lower fixed costs per collector area. Solar gets a lot more viable a lot quicker. What happened of course is that engineers specified the old school boxed and glazed or evacuated tube collectors. They didn't even consider unglazed collectors.
When we look at these performance curves we see that unglazed collectors are affected by wind and as we move right on the x axis (water getting warmer relative to air temperature) we see why engineers like the evacuated tubes and boxed and glazed collectors. They retain their efficiency into marginal weather conditions and into the higher end of the heating range. What engineers failed to recognize or perhaps never thought to even look at was the fact that most hot water heating is done at the low end of the temperature range are even more efficient per area than the other types and on top of better efficiency they are far less expensive. The system has been installed for a year now and we've monitored it with our web based monitoring . The monitoring is not internet connected so the data is not always up to date and we've lost some data but we've still proven that we've displaced more energy here with this system than we would have with more expensive technology. We've also proven that cost effective solar hot water is possible. Its possible to deliver solar at $100/GJ That's $100 in capital cost up front in exchange for 1 GJ of annual energy production. If energy costs $10/GJ after boiler efficiency is included (which is close even with today's low natural gas prices) then its a simple ten year payback period. Others will brag that they are doing better than 10 years. They are incorrect. There's no way to do better than this kind of economics against cheap natural gas.or is there? Some municipalities like Sechelt, Esquimalt, and Kimberley have installed our solar panels at their municipal facilities. They have gone one step further with all this. They are using the Powerstrips to heat a tank of water and that tank of water is the source for a heat pump. Heat pumps utilize low grade heat. Ground source heat pumps for example might take ground heat at 10C and use it so the ground cools down to 5 degrees. That 10C to 5C drop in ground temperature is converted through the heat pump to heating water at 60C or air at 20C or a pool at 29C. Heat pumps take low temperature energy and pump it up to a higher temperature for use. Solar needs to operate at low temperature in order to be able to take advantage of unglazed collector cost efficiency. Heat pumps are the means by which we can utilize that low grade heat. We've known this in the solar industry for decades but we've been distracted by grants for the tried and true conventional approaches. Since this is a blog posting about municipal pools I need to mention something. Solar heating municipal pools has been a failed experiment. Its usually a bad idea because the pool temperature can not fluctuate and it needs to in order to store solar energy, otherwise the only gains made are gains that can be made during a sunny day and at these times there is usually too much heat. The sun is heating the space (indoor pool) and the heat pumps are dumping that heat outside or if needed into the pool water.
Municipal outdoor pools are only used in the heat of summer. Not much heat needed then and again thru half that season the sun on the pool is increasing the pool temperature and it started the day at setpoint so its a heat dissipation requirement and solar heaters never turn on. The only way solar works is when you are allowing the pool temp to fluctuate and its most beneficial in early and late season, before and after municipal pools operate. When we see solar on Aquatic Centers these systems are heating water for showers, not heating the pool.

The development with solar energy is as controversial as ever; but one thing you can’t deny that it’s getting more efficient and affordable with every passing year. Solar energy has become a main source of household energy supplier and effective for a homeowner. One of these steps is implementing the technology of solar water heating systems.
The Working Principle of Solar Water Heaters
Solar water heating systems heats the water directly that gets pumped into your home. There are two main types of solar water heaters available on the market, active and passive. Both types can depend on the climate. Therefore, it’s highly recommended to try them during the warmed months of the year.
Active solar water heating systems utilize pumps for water circulation through pipes located in the solar panels. Passive solar water heaters use a storage tank and solar collection tank where hot water can be kept for use later.
The Significance of Solar Water Heaters
Clean and highly efficient water heating
Solar energy is free and abundant. It has no carbon footprint. If you want to get away from hydro and gas power, solar water heater is a perfect option. It is perfect for those who live in an area that receives a lot of sunshine as approximately 80% of the radiation is converted into heat energy.
Great return on investment
Though solar power needs an initial investment to install, it replaces the energy you would be buying from the power company. Depending on the location, the investment will offer electricity savings. It’s estimated that your water heating bill would be minimized up to 80% with a solar water heating system.
Easy to maintain and operate
The solar water heaters don’t need much maintenance. All you need to do is to circulate a water softener in the pipes during every 3 years.
There are few moving parts in solar water heaters; but in general the system doesn’t produce much noise.
Unlike other solar technology that required the installation of 16 solar panels, the solar water heater requires two or three. You’ll require some additional space for the storage tank if you’re utilizing the passive process, but other than that it doesn’t take up enough space.
Renewable heat benefits
Commercial and domestic properties are entitled to maintain the renewable heat incentive. This means, you will get paid for generating your heat energy regardless of whether you utilize it. There is a user-friendly calculator available that tells you how much you can earn through the scheme. It can be hundreds of dollars every year.

Solar water heaters are the easiest possible ways to harness the solar energy directly. Solar water heating kits are easy to install and provide unparalleled performance and safety. They are widely used in commercial premises like hotels, Laundromats, restaurants, car washes etc. Here are a few types of solar water heaters discussed below:
Pre Heat Solar Tank System
Pre Heat Solar Tank System comes with two tanks, first is a solar pre heat tank and is a basic solar hot water storage tank. This pre-heat tank is used to provide warm water to an existing hot water tank. This heating kit is the most common retrofit as it utilizes the existing hot water tank and requires very little retrofit to the plumbing.
The main supply line is routed to the pre-heat tank and drawn back into the supply after it is heated. However, the most efficient solar water heaters use the basic theory of stratification. In the stratification process, the solar water heater is heated using Thermosiphon or a very slow pump.
Though the system ensures a slow mixing of water, the top layer is always the hottest. When the top water draws into the main tank, the hottest water is used first. Though the average household used hot water in batches, the solar water heating system can supply according to the daily requirements.
Solar Tankless Water Heaters
In a solar tankless water heater, the water is pre-heated through the solar storage tank before entering the tankless heater. For instance, the main line water is coming into the home at 40 degrees can be heated in a pre heat tank at 120. If the tankless heater is set as 140 degrees, it only needs to supply 20 degrees of heat energy as compared to 100 degrees without the pre heat tank. This means, you will get significant savings.
Solar Combo Tank System
The specially designed solar combo tank system is a combination of a solar pre-heat tank with an electrical backup heater in a unit. This tank uses an internal heat exchange in the bottom part of the tank. The solar loop is piped through this loop and heats water effortlessly.
The top of the tank consists of an electric heating element to the top up the water temperature quickly or help you in the days of no sun.
While there are different solar pre-heat tanks with heat exchangers, there are few that are built only for the Middle east and come with the proper certification. These systems are perfect for home installations or even when your existing water tanks needs replacement.
New Compact Solar Water Heaters
The new compact solar water heaters are used for those who need solar heating for domestic hot water applications. They are right alternatives to the advanced closed loop solar water heaters and don’t have any moving parts or pump.
These systems work well in southern climates that seldom get freezing conditions and are perfect for 20F. They usually sit on the ground or are mounted on the roof. An 80 gallon storage tank is integrated with solar vacuum tubes and offers hot water to a family of 4–5 persons.
For more information about solar water heating system, please visit solar water heater dubai or call us at +971 4 252 2966.
Your plan to use a solar pool heating system in the home, hotel or health center is a very reasonable and admirable decision from the angle of usability and long-term energy savings. In the countries like Dubai, UAE there is enough reason to take advantage of the unlimited solar energy for the pool heating needs during the summer and manage home/space heating and domestic hot water in the winter months.
5 Point Guide for Solar Pool Heating Buyers
As a first time buyer, you can always seek assistance from the supplier to guide you on the right kind of solar pool heating system. But some of them have limited stock of the type of pool heating system they deal with. Below is a 5-point guide to pick the most perfect solar pool heating system for your use:
1. Two Major Options: — In the whole world, there are normally two major kinds of solar pool heating systems available. The 1st type is the solar flat plate collector system. It uses collectors made of rubber or PVC that are mounted flat on the roof of the pool owner. The 2nd type is modern age solar pool heating systems using high-performing solar vacuum tubes to deliver solar energy indirectly to the pool. The flat-plate collectors are perfect for areas that are not vulnerable to heavy frosting. However, the evacuated tube solar pool heaters employing antifreeze glycol liquid to heat the pool water in frosty conditions. The second type are closed loop systems working with a heat exchanger to save you from excessive pressure or wear on the pump and lowering the pump operating cost by around 30%.
2. Installation Cost and Components: — If you install an open loop type solar pool heating system, the two key components that would keep it functional are the solar collector panels and the water storage tank. A family of four persons will need about 2 panels of solar thermal collectors and a 300–360 liter water tank. For pumping the water to the roof and circulate it through the pool heating system you will require a solar heat pump powered by photovoltaic cells or electronic controller.
Installation of evacuated tube solar pool involves a heat exchanger ruling out the need for any oversized pumps to lift the large volumes of water to the rooftop. Instead, all that is required is a small size pump drawing less than a light bulb with longevity of 20 years or more.
3. Repays and Incentives: — Most solar pool heating systems are able to repay the investment cost yielding great savings over electricity and fossil fuels. With reduced cost of ownership, the pool owners are likely to be granted rebates and incentives by the state government for using solar pool heating systems. You may even check with any local supplier to know about the incentives offered in your area.
4. Instant Quote: — After getting sure about the kind of solar pool heater you want to install, you should ask for instant quotes from a couple of suppliers in the area. Be ready to answer a few questions as well: how many people are there? Do you have any domestic hot water system? Do you have a connection to a gas or electric system? What time of the day is pool water in use?
You also need to confirm if the offered quote includes installation charges and how much time it will take to operate. It’s better to know about the system warranty, life span, and other profitable programs available for the user.
5. Supplier Credibility: — In choosing your solar pool heating system, make sure that you contact the most professional and reliable supplier. You can personally visit the showroom or virtually visit it online and get to know about its service standard as well as market reputation.
