What is Solar Water Heater?
A solar water heater is a hot water system that utilizes solar energy (energy from sunlight) to heat water in cost-effective solutions. It fits on a terrace or any open space on the top of the building where it gets sunlight is then used to heat water and store it in an insulated tank. The solar water heater does not connect to the electricity grid; however, used to get the sunlight throughout the day to heat the water, and store it in the storage tank for your home, or any other desired applications.
The solar water heater incorporates high density compressed PUF insulation and an efficient heating element, which is capable of helping it to store hot water up to 48 hours. Therefore, it is best suitable for homes, apartments, hostels, and several other buildings. The solar water heater for home is made up of anti-corrosive material and advanced technology. Some of the features such as energy efficiency, durability, safe to use, and easy installation are the main reasons for which, the solar water heater has acknowledged in the market.
The solar water heater is developed by all standards of quality and safety, thus ensuring safety for use at home. SolarClue is an online platform to buy solar water heater directly from top brands such as Supreme, V Guard, Havells, EMMVEE Solarizer, Racold, and Kamal Solar.
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.
Solar Panel Price in India
The solar panel price in India is different from one brand to another. Based on several manufacturers and dealers, the price of the solar panel decided. You can check out the solar panel price list from top solar panel manufacturers at SolarClue and buy the preferred yet best solar panels as per your budget.
Everyone wants to spend their money on buying the product, which is of superior quality. Comprehending this fact, several brands of solar panels on SolarClue have stepped forward in the market with different price lists, based on the products’ reliability and durability.
You can find the solar panel price list from different brands on SolarClue. There are different categories and pricing of solar panels in India available with SolarClue, and according to those classifications customers can choose their items. They also can compare solar panel prices and select the best one which suits their budget.
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.
A solar battery is simply a
battery charged and stored with solar power or energy and discharges power or
solar electricity when needed. Solar batteries are rechargeable and used in
off-grid PV systems to store excess electricity for future use. Some categories
of solar battery banks use wet cells, whereas others use sealed or gel cell
batteries and both the categories of batteries have their different
requirements in terms of temperature, mounting, and ventilation.
Solar batteries are C10 rating
deep cycle batteries designed to connect with the best solar charge
controllers, inverters for providing power backup at night. Solar batteries are
designed in such a way to charge with the help of solar panels by collecting
sunlight in the day time. The solar battery and charger operate with its only
component like lead, which requires water top-up maintenance in 3-6 months.

SolarClue on two different brands provides Tabular Batteries, which are built-in tall height. This kind of batteries manufactured using three main chemical compositions, such as lead-acid, lithium-ion, and saltwater.
Battery Backup Time, Warranty and its Price
The backup time of solar battery
depends upon its AH (Ampere Hour) and the higher the battery AH, the higher
will be the battery backup time. Generally, a 150 AH battery gives a backup of
around 3 hours on 400-watt power consumption. 150 AH is bestselling rating
battery especially in India, for example, it can last up to 3-4 hours if you
use LED lights, few ceiling fans, LED Television, mobile phones, and laptop
charging. For higher duration backup, one can go for those batteries which are
having higher AH.
The warranty for every solar
battery offers based on two aspects, i.e., Replacement Warranty and Pro-Rata
Warranty. In case, your battery fails, during the replacement warranty period,
the particular Brand is responsible to replace it with a new battery. And,
during the pro-rata warranty period, a new battery is offered at a discounted
price, known as buyback offer.
The solar battery price is most importantly, dependent on
its AH and Warranty. The other important factors which impact the cost of
batteries are Brand, replacement warranty offered on batteries, the capacity of
the battery measured in Ampere Hour (AH). The solar battery price in India is
uneven since 60% of batteries manufactured by local manufacturers, and the rest
40% captured by different brands.
