Solar Water Heater – How it works, Advantages, Cost Efficiency

What is Solar Water heater?

A cost-effective approach to produce hot water for your home is with solar water heaters, often known as solar domestic hot water systems. Solar water heater is a device that helps in heating water by using sunlight and energy of sun, to collect the energy of sun solar thermal collector is being used. This energy is totally free. Solar energy (sun rays) is used for heating water. Water is easily heated to a temperature of 60-80o C.

How does solar water heater work?

Solar water heater is a device that helps in heating water by using sunlight and energy of sun, to collect the energy of sun solar thermal collector is being used. The solar thermal collector panel receives sunlight. The solar radiation is absorbed by a black surface inside the collectors, which then distributes the heat energy to the water running through it.

In order to prevent heat loss, heated water is collected in an insulated tank. The thermal siphon system ensures that the automatic flow of water from the tank via the collectors and back to the tank is maintained. Solar water heaters come in two different varieties depending on the collector system: A solar water heater is made up of an insulated storage tank for hot water and a collector for gathering solar energy. You can always use the heated water that has been kept.

What are some advantages of a solar water heater?

Solar water heater also offer numerous other advantages in a cost-effective manner:

• Cost Saving and Reliability : After installing a solar water heater on your property, you can anticipate seeing a change in your energy expenditures immediately away. The solar water heater uses energy from the sun. This indicates we do not have to pay a single amount of money to the power grid for using electricity. Being a renewable source of energy, it is completely free and available everyday except rainy day. But it also can be solved by figuring how to fine-tune our panel to optimize the performance in cloudy weather. Because it is costly and frequently unavailable owing to power outages, electricity cannot be used to heat water. A solar water heater can be up to 85 percent more efficient than a traditional water heater. Depending on how much hot water is consumed, a solar water heating system with a capacity of 100 liters per day that is suited for 3–4 people can save up to 1500 units of electricity annually.
• Less area: Compared to photovoltaic panels, solar thermal panels often require less space. When compared to an array that is utilized to generate enough power for a residence, fewer are needed to heat water.
• Low maintenance: After installation, solar water heaters require little upkeep and can last up to 20 years.
• Reduced carbon footprint and Efficiency: Using renewable energy may be eligible for tax advantages, making a home more environmentally friendly. Efficiency here means the solar panels convert almost up to 80% radiation into the heat energy without making use of any external fuels.

Are solar Water heaters worth the investment?

Installing solar water heater is worth the investment. As it uses renewable energy, environment friendly, reduced carbon emission and also the lifespan of solar panel is quite good it is worth the investment.
