Parts of the Solar Water Heater

A solar water heater consists of a flat plate solar collector, a storage tank (kept at a height behind the collector), and connecting pipes. The collector is comprised of copper tubes welded to copper sheets (both coated with a highly absorbing black coating) with a toughened glass sheet on top, insulating material at the back, and the entire assembly placed in a flat box. There are certain types of solar water heater, where evacuated glass tubes used instead of copper and a separate cover sheet along with an insulating box not required in this case.

Solar Water Heater Working Principle

The solar water heater is installed on the roof of the building, or open ground with the collector, and connected towards facing the sun for continuous water supply. The water flows through the tubes or solar panels are capable of absorbing solar heat to provide hot water. Then the heated water is stored in a tank for further use and the tank covers with a glass lid to prevent the loss of sunlight or heat due to convection and radiation. And, the hot water gets stored in the storage tank remains hot overnight as the tank is insulated. This is all about the working principle of the solar water heater.

The solar water heater price in India is different from several manufacturers and dealers. You can check out the list of prices from the top solar water heater manufacturers at SolarClue and analyze the features of the best solar water heater then select the best one.

Types of Solar Water Heater

There are mostly two types of solar water heaters available on SolarClue.

Flat Plate Collectors System (FPC): It is a typical solar water heating system and known for its longer life. The flat plate collector system is also called a selective coating that consists of an absorber plate and covered on its sun-facing surface with an absorbent coating. The absorber plate is placed in a top open box to protect it from weather and incorporated with a grid of metallic tubes and sheets that allow water to flow. Sheet absorbs the solar radiation falls on it and transfers it to water. The space between both the (front & back) sides of the absorber and the box is filled with insulation to reduce heat losses. Flat plate collectors are stated based on their area, commonly 1x2 m size.

The FPC water heater also can work in colder regions with freezing temperatures, but it needs an anti-freeze solution that makes the system expensive. A heat exchanger with an FPC system is required in those areas with salty water to avoid scale deposition that can impact the heating capability of the system.

Evacuated Tube Collectors System (ETC): This is another type of water heater made up of glass, hence fragile by its nature. It is ideal for colder regions where the temperature is subzero. The places where the water quality is salty, ETC requires regular cleaning due to the deposition of salt on the inner surface of glass tubes.

Each of the evacuated tubes contains a glass outer tube and a metal absorber tube that is attached to a fin. The fin's coating generally absorbs solar energy but prevents radiative heat loss. This particular type of water heating system is used more frequently for U.S. commercial applications as compared to other uses.

Both the types of water heaters are manufactured with, or without a pump, available on SolarClue. The water heater with a pump is used to move water from collectors to the storage tank. The other water heater without a pump is used utilizing the thermosiphon principle to move water from collectors to the storage tank automatically.

What is solar panel and how it works?

Solar Panel is also known as Photovoltaic Solar Panel, made using smaller units of silicon. This is called a solar cell, which converts solar energy into electrical energy. Silicon is a semiconductor inserted between conductive layers in a solar cell.

How solar panels work? The process of solar paneling starts during the day time when proper sunlight is there. The sun rays fall on Solar PV Panels that are installed on your rooftop, and photovoltaic refers to the scientific process by which solar energy gets converted into electrical energy.

There are several silicon cells within each PV panel, and these cells react with photons (unit of light), which come from the sun to produce DC (Direct Current) or electricity. The direct current (DC) then travels into an inverter that converts it into AC (Alternating Current), which further used in your home, office, playgrounds and many other places. After this, AC current transfers to the distribution network in your home, which is capable of powering electrical appliances of your house. When Solar Panels produce more electricity than your home is using, the extra electricity gets shifted or stored in the grid. And, you can avail of the benefits for the extra electricity that your solar panels generate. Moreover, solar panels are available in different sizes and price ranges.

Working Principle of Solar Panels

Solar Panels work on the principle of the photovoltaic effect, which is a method of producing direct current electricity based on the principle of the photoelectric effect. Photovoltaic directly converts solar energy (sunlight) into electricity. When certain materials expose to sunlight they absorb photons and then release free electrons, and this phenomenon is called the photoelectric effect.

Solar cells or photovoltaic cells are used to convert sunlight into direct current (DC) electricity. Though a single photovoltaic cell does not produce enough amount of electricity, hence several photovoltaic cells are mounted on a supporting frame and electrically connected to form a photovoltaic module or solar panel. The current or electricity that solar panel system provide is dependent on the effectiveness of sun rays.

Types of Solar Panels

Solar Panels are classified into two types such as Monocrystalline Solar Panels and Polycrystalline Solar Panels.

Monocrystalline Solar Panels:

Monocrystalline Solar Panels are made using extremely pure mono (single) silicon crystal that helps in converting solar energy into electricity. Monocrystalline solar panels are suitable for easy installation in smaller areas, which requires a reasonable price. However, the monocrystalline solar panel installation is ideal for a larger area, but it makes it expensive. Users will be able to get the most electricity output according to the monocrystalline panels used.

Polycrystalline Solar Panels:

Polycrystalline solar panels are made using poly (multiple) silicon crystals and known as the most commonly used type due to price and efficiency. The cells used in Polycrystalline are a small amount of quantity that makes the Polycrystalline Solar Panels a bit less efficient. For this reason, users can install a large number of polycrystalline panels to generate electricity to meet their consumption needs. As compared to Monocrystalline Solar Panel, Polycrystalline Solar Panel is considered the commonly used type as they maintain a good balance between pricing and effectiveness.

Difference between Monocrystalline and Polycrystalline Solar Panel

The difference between Monocrystalline and Polycrystalline solar panels is the advanced technology that has made them practically interchangeable. Owing to the manufacturing process and robust technology, Monocrystalline Panels are quite expensive as compare to Polycrystalline Panels. The monocrystalline solar panel comes with black and dark blue color, whereas polycrystalline panel appears in the blue mottled.

Monocrystalline Solar Panels are more efficient than polycrystalline solar panels thus, you can use slightly more power in the same size and space of monocrystalline panels. But polycrystalline panels need more equipment to produce the same amount of electrical energy as monocrystalline. For this reason, the solar panel cost is less for polycrystalline. Interested buyers can purchase any solar panel through online and also by visiting stores.

When it comes to temperature, Monocrystalline panels handle the heat slightly better than polycrystalline solar panels. This temperature difference can be noticeable especially in extremely hot areas such as deserts, as compared to residential regions. Last but not least, monocrystalline can perform in a better way even on hazy skies than polycrystalline panels.

Solar Components are important for every home solar electric system to help in producing electricity and converting it into the alternating current; thereby using in home appliances, storing excess electricity, and maintain safety.

Solar components are classified into seven categories such as Solar Pumps, Solar Charge Controllers, Solar Combiners, Solar Mounting Structure, Solar Tools, Solar Cables, and Solar Surge Protection Devices. These all are functioned using solar energy (sunlight), which turns into electricity. The entire solar components are manufactured and stringently inspected as per International Quality and Safety Standard.

Solar Pump

The solar pump is a solar water pumping system operated using solar energy to pump clean water. The solar pump is ideal, especially for rural localities (beyond the reach of power lines), where people are unable to avail of electric consumption by using the local electricity grid.

Solar pump or solar-powered water pump is in demand due to its robust construction, easy installation, eco-friendliness, and minimum maintenance. Solar pumping is the best alternative for fuel-burning generators and windmills, in which the electricity is provided by one or several Photovoltaic (PV) panels to offer water even if using without electricity. The water supplied by the solar pump is used to irrigate crops, provide clean drinking water, and also offer water for livestock. Apart from these, some other application areas for which solar water pumping system is used including fountains, pools, ponds, and home pumps.

A solar water pumping system consists of a solar panel that provides power to an electric motor, which in turn is capable of powering a bore or surface pump. Hence, the water is pumped from the ground into a storage tank that provides a gravity feed, and for this reason, energy storage does not require for the solar pumping system. The life span of a solar pump or solar water pumping system is a maximum of 20 years, but a solar panel of the pumping system needs cleaning from time to time to run properly. People can purchase it as per their requirements because the solar pump price is varied from its manufacturing capacity, sizes, patterns, and different brands.

Benefits of using solar pump

Solar Charge Controller

The solar charge controller is a device, which maintains the proper charging voltage in batteries of any solar appliances. All solar electric systems with batteries should have solar charge controllers. The solar charge controller regulates the voltage, prevents overcharging and allows batteries to charge when required, because batteries can be overcharged if it feeds continuous voltage.

The main function of solar charge controller is to prevent overcharging of the batteries and regulates the amount of current the PV modules feed into a battery bank. However, charge controller can block battery bank current from leaking back into the photovoltaic array during night or cloudy times for saving to drain the battery bank.

Most home solar systems are built with a battery backup controlled using solar charge controller, which ensures that a consistent amount of electrical power is sent to the and the backup batteries of any solar system do not discharge during night or absence of sunlight. Solar charge controller price is very minimal so that anyone can buy it as per their necessities.

Solar charge controller or solar battery charger comes with two types of sizes and technologies such as MPPT (Maximum Power Point Tracking) and PWM (Pulse Width Modulation) that are capable of functioning an off-grid power bank system properly. Charge controller is used within an off-grid or hybrid solar system with appropriate battery back-up.

Benefits of solar charge controller

• Works to control voltage and watts from Solar Panels

• Reduces the voltage of solar panels when a solar battery’s voltage is high

• Helps to maintain stable energy by preventing overcharging and protecting against overvoltage

• Stops reverse current during night or when sunlight is not available

Solar Combiner

The solar combiner or solar combiner box is a device operated using solar energy (sunlight) that combines the output of multiple strings of PV modules for connection to the inverter. Solar combiner is developed in such a way to bring the output of several solar strings together. Usually, each string conductor lands on a fuse terminal and the productivity of the fused inputs are then joined onto a single conductor that connects the combiner box to the inverter.

Solar combiner box also combines incoming power into one main feed, which distributes to a solar inverter that is capable of saving labor and material costs through wire reductions. Solar combiner is engineered even to provide overvoltage as well as overcurrent protection facilities to enhance inverter protection and reliability.

The solar combiner generally exist in between the solar modules and inverter, which is the correct position. Solar combiner can limit power loss when it is positioned in the solar system. Solar panel combiner box and solar string combiner box are two different types of solar combiner. Moreover, solar combiner is usually used in the larger commercial and utility scale PV power plants (greater than 500kW).

Benefits of using solar combiner

• Helps in improving safety of solar panels and the entire photovoltaic plant
