What is a residential solar water heater?

The residential solar water heater system captures the heat of the sun and uses it to heat water for households, businesses. Unlike solar photovoltaic (PV) systems, which collect sunlight and convert it into electricity. Residential solar water heaters absorb only the heat of the sun and transfer it to the hot water supply system. With home solar water heaters, you can reduce energy and utilities without sacrificing comfort or reliability. Even in cloudy days and nights, the system can be used with your solar water heater, so you can enjoy hot water 24 hours a day, 7 days a week.

 

How does a residential solar water heater work?

Solar water heaters come in a variety of designs, including collectors and water tanks. All of which use the heat of the sun to add water.

Solar collectors are usually installed on the roof of your house to absorb the heat of the sun.

A pump loops the heat transfer fluid from the collector through the heat exchanger of your solar storage tank.

The heat exchange of the heat of the sun is passed on to your water supply.

Hot water flows into your existing residential solar water heater. And residential solar water heaters provide backup heating when the sun is not shining.

 

Do residential solar water heaters work on cloudy days?

Solar panels produce the most electricity (not surprising), but is solar panel working in cloudy weather? Yes, typical solar panels can produce 10-25% of rated capacity. However, it doesn't matter, what matters is how much sunshine you get all year round. Cloudy days are likely to come, but on average, it does not affect the return on investment of solar panels.

When you are researching how solar energy can help you save on electricity bills, you will consider how much sunlight you can get throughout the year, not any specific day. If you generate more electricity than you need, your power company will calculate the products you produce in a year because they will calculate how much you have to pay.

The good news is that even if you live in a city that is not known for its sunshine, you may still get enough sunlight in a year, and solar energy makes sense to you. In fact, some places with the most solar installations are not known for their sunlight.

 

Summary

It turns out that residential solar water heaters work on cloudy days, and even in cloudy conditions, there is usually some radiant heat that can be used to heat the water, even though it is smaller than the sunny days. If you want to buy a cost-effective, safe and reliable residential solar water heater, the Jiangsu Sunpower Solar Technology company has the perfect product.
