Solar Guide | Read Before you Buy

There are several factors you should consider to ensure that you choose the right system for your needs. Here are some key considerations.

 1.Size

The size of the solar water heater should be based on your household’s hot water needs. A larger family will require a larger system to provide sufficient hot water.

 2.Efficiency

 The efficiency of the solar water heater is an important consideration as it will affect the amount of hot water the system can produce and how much energy it will save. Look for a system with a high-efficiency rating.

 3.Climate

 The climate in your area will affect the performance of the solar water heater. If you live in a colder climate, you may need a larger system to compensate for the reduced sunlight available in the winter months.
 

4.Type of system

 There are two main types of solar water heaters – passive and active. Passive systems are typically less expensive but are less efficient. Active systems use pumps to circulate the water and are more expensive but more efficient.

5.Warranty and maintenance

 It’s important to consider the warranty and maintenance requirements of the system before you buy it. Look for a system with a good warranty and make sure you understand what maintenance is required.

 6.Cost

 The cost of the system is obviously an important consideration. Consider the initial cost as well as any ongoing maintenance costs and the potential energy savings.

By considering these factors, you can select a solar water heater that is best suited to your needs and can provide you with an affordable and efficient source of hot water. It’s always a good idea to consult with a professional installer who can help you choose the right system for your home and provide guidance on installation and maintenance.

What are the types of solar water heaters available?

1.ETC (Evacuated Tube Collector) solar water heater 

 

ETC (Evacuated Tube Collector) solar water heater is a type of solar water heating system that is used to heat water using energy from the sun. It consists of a series of glass tubes that are sealed at both ends and coated with a special material that absorbs solar radiation.

The tubes are connected to a manifold that carries water, which is heated as it circulates through the tubes. The hot water is then stored in an insulated tank for later use.

ETC solar water heaters are highly efficient and can provide hot water even on cloudy days. They are also environmentally friendly, as they do not produce any greenhouse gas emissions. They are commonly used in residential, commercial, and industrial settings and can provide significant energy savings over traditional water heating methods.

2.Flat Plate Collector Solar Water Heater 

 

FPC stands for “Flat Plate Collector", which is a type of solar thermal collector used in solar water heating systems. A solar water heater is a device that uses the energy from the sun to heat water for domestic or commercial use.

In an FPC solar water heater, flat plates made of materials such as copper used to absorb the sun’s radiation and transfer the heat to water, which flows through tubes in the collector. The heated water is then stored in an insulated tank for later use.

FPC solar water heaters are typically more efficient than other types of solar collectors, and they can be used in a wide range of climates. They are commonly used in homes, hotels, hospitals, and other commercial and industrial settings. The use of solar water heaters can help reduce reliance on non-renewable energy sources and lower greenhouse gas emissions.

 

Minimum Requirements to install a solar water heater

 

 

 

 After the Plumbing work is over, For the first time the water should be let in only 3 hours after sunset.  that is by 10.30 pm or 1 hour before sunrise that is 5 am.  This is because the tubes have to cool down before water is let in, or else the tubes will break within second.
