Solar Water Heater

Silent Features of Solar Water Heating System:

• Fuel Saving- A 100 liters capacity SWH can save 1500 units of electricity annually.

• Beneficial for Environment- A Solar Water Heater of 100 liters capacity can prevent the emission of 1.5 tons of carbon dioxide per year.

• Total Life- 15 to 20 years of life span (durability) approximately.

• Costing- Rs.15000- 20,000 for a 100 liters capacity system and Rs.110-150 per installed liter for higher capacity solar water heating systems.

• Payback period- 3-4 years’ time duration for payback when electricity is replaced 4-5 years/when furnace oil is replaced 5-6 years/when coal is replaced. 

• Solar Water Heater has the longest warranty period as compared to other solar energy devices.

• Solar Water Heater is one of the most reliable and durable devices.

 For night, you will have 2 options in the inverter grid and up to 50% batteries. If you choose govt power/grid, the grid will run your load and in case of power cut, solar batteries will power your home. If you choose the battery for second priority, the battery will be drawn up to 50%. In case, your household consumes more than 50% battery, the extra electricity required to power the house is drawn from the utility grid.

How Does The Solar Water Heater Works?

First of all the Sun rays fall on the Solar Collector, which is consisted a black absorbing surface (absorber) that absorbs solar radiation, and transfers the heat energy to water flowing through it. After this, heated water is collected in a tank, insulated to prevent heat loss. Then the circulation of water from the tank through the collector and back to the tank continues automatically. An Insulated Storage Tank of a Solar Water Heater is useful to collect solar energy by collector panels to store hot water.

The solar water heater is one of the popular solar system devices that utilise solar energy. The solar water heater is a cheap yet cost-effective way to supply hot water for your home, and it also uses solar radiation or sunshine as fuel to heat water. We are blessed with unlimited solar power at no cost.

Though the solar water heater or solar water heating system is the cheapest method of heating water, we don’t require to pay for the heat of the sun. It can be used for homes, hospitals, nursing homes, community centres, hotels, dairy plants, ashrams, hostels, swimming pools, canteens, and industries.

The solar water heaters are manufactured in different designs, but, they have common components:

• Solar Collector (helps in collecting solar energy)

• Insulated Storage Tank (its purpose is to store hot water)

• Supporting Stand

• Connecting Pipes and Instrumentation, etc.​

Top 5 Benefits of Solar Water Heaters

Why should you choose solar water heaters for your home or business? Here are some of the biggest benefits of investing in a solar hot water system.

​

Free Energy

Once you invest in a solar hot water heater, you’ll start to get that money back in the form of free energy. The typical home will see an average of at least a 50% reduction in water-heating electricity use. If you live somewhere that gets a lot of sun, like Arizona, you could see as much as a 90% decrease in your water-heating bill.

Who wouldn’t want to save money and get free energy?

​

Reduced Carbon Footprint

The general consensus is that climate change is occurring and that carbon emissions are a major contributing factor. A solar water heater uses the renewable energy of the sun to warm up your home’s water.

If you can use solar energy to heat up water, that’s less fossil fuel or natural gas being used and released into the atmosphere from traditional electric or gas water heaters. That means you’ll be helping save the environment in addition to lowering your gas or electric bill.

High Efficiency

Heating up your water directly from the sun’s rays is much more efficient than converting sunlight into energy that is then used to warm up your home’s water. Why take two steps to heat up your water when you can do it in one step?

​

They Take up Less Space than Traditional Solar Panels

Since solar water heaters are more efficient than traditional solar panels, the average home only requires one to three solar water heater panels. If you don’t love the idea of your entire roof being covered in solar panels, then a solar hot water heater may be a great option.

​

They’re Cheaper than Solar PV Panels

Since you need fewer solar water heater panels, they’re much cheaper to install than traditional solar PV panels. If you can help save the environment and reduce your gas or electric bills for a lower initial cost, then what’s holding you back from making that investment?
