Conventional water heaters link straight to your home grid energy. Solar-powered water heaters, however, obtain power coming from solar energy collectors, that collect energy straight from the sun. This kind of system minimizes your reliance on the electrical grid. In the process, it can help you save cash and going green for the improvement of the environment.
Benefits of Solar Water Heater
If you’re looking for installing the solar water heater for your home or office, allow us to inform you that here are the benefits you’ll get.
Essentially, the solar panel utilizes the sun’s energy. Meaning we don’t need to pay a single penny to the power grid for utilizing electricity. As a renewable source of energy, it’s totally free and accessible every day. All we must do is determine the way to fine-tune the panel to maximize the performance in cloudy weather.
Among the main reasons why solar panel is better compared to some other type of energy is because of the efficiency in heating water. Efficiency here implies that the solar panels can transform nearly up to 80% radiation into the heat energy without the need of using any external fuels.
It will cost much less to install a solar panel compared to a PV panel. A great way to gain benefits is by transferring the unused unit back in the electricity grid. They’re a one-time investment for long lasting advantages.
You get Hot Water even in Power Outage
You could possibly get hot water even if you’re dealing with power cuts, because you don’t rely on electricity for the hot water.
Save for Natural Environment
The world is taking ‘green’ and there isn’t any greener energy than the solar panels. They’ve got no reliance upon fuels, have zero-emission, and lesser carbon footprints.
Solar water heaters don’t need high maintenance. It simply calls for easy cleaning. Since it doesn’t have any moving components, there won’t be any tear and break that would require regular repairing attention. The maker of solar water heater make sure that it would work for nearly 20-25 years yet often work longer.
Solar water heater needs an initial expense however is definitely a better substitute for heating water. The one thing we have to remember is the correct quantity of solar panels to be able to meet the correct needs of heating at your house ..
Types of Solar Hot Water Heaters
You can find 5 types of solar hot water systems:
These systems heat up the water or an antifreeze fluid, like glycol. The fluid goes up through natural convection coming from collectors into the storage tank, that is put in a higher levels. Basically no pumps are needed. These systems are most effective in places having higher levels of solar radiation.
These systems pump water coming from storage to collectors throughout sunny hours. Freeze protection is acquired by recirculating hot water coming from the storage tank, or through flushing the collectors. Considering that the recirculation system raises energy consumption, whilst flushing cuts down on the hours of process, direct-circulation systems are utilized only in locations where freezing temperatures are rare.
Such systems are often indirect water-heating systems. Treated or untreated water is distributed via the closed loop, and heat is moved to potable water via a heat exchanger. Whenever no solar heat is accessible, the collector fluid is depleted through gravity to prevent freezing and convection loops where cool collector water decreases the temperatures of the stored water.
Indirect Water-Heating Systems
With these systems, freeze-protected fluid is distributed via a closed loop and the heat is moved to potable water by way of a heat exchanger with eighty to ninety percent efficiency. The often utilized fluids for freeze protection are water-ethylene glycol solutions as well as water-propylene glycol solutions.
On this indirect system, the collectors heat air, that is transferred via a fan using an air-to-water heat exchanger. The water will be employed for domestic or service needs. The efficiency of the heat exchanger is around 50%.
