The popularity of solar powered systems is rising everywhere. The system offers numerous advantages to the user and the environment as an alternative to electricity. As a result, most people have opted for this type of system.
Most people want to maximize their use of solar energy by integrating it into their homes. There are a few factors to understand if you want to use solar energy for large loads like a water heater.
They are of two categories;
Direct solar water system ( open loop )
The simplest and most effective type of solar heating system is the open-loop. In this mechanism, portable water is taken directly from the storage tank, circulated through the array, heated, and then returned to a port in the tank for re-circulation.
Advantages
- Low price
- High Productivity
Disadvantages
- Frost damage is possible.
- In areas with hard water, collectors can scale.
Indirect solar hot water systems ( closed loop)
Because it is a closed-loop system, indirect solar hot water systems are likely to be more effective than other heating systems. Since pumps must circulate, pumps must circulate the temperature distribution liquid to heat the water; these systems are active.
Advantages
- Less maintenance is required because there are no additional burners.
- Less expensive – no additional venting or fuel lines to install.
- Better performance – more hot water available with faster recoveries.
- Simple to size and install.
Disadvantages
- Dependent on climate
- Heats only water
A solar water heater is an investment, particularly when compared to a conventional water heater. For such a miniature solar system, you also need room on your roof or the side of your house. But do the advantages outweigh the extra cost? Let me take you through some benefits.
Monthly savings
A solar water heater can meet 80% of your hot water requirements. It allows you to save money on your monthly electricity bills. In addition, the initial investment in a solar water heating system can be recouped quickly depending on use and has a lifespan of about 40 years. A straightforward equation explains it.
High Productivity
Instead of converting sunlight into electrical energy and then using that energy to warm the water in your home, heating your water straight from the sun’s rays is far more efficient. Why bother with two if you can heat your water in one step?
They are less expensive than solar PV panels.
Because fewer solar heating panels are required, they are much less expensive to install than typical solar PV panels.
Easy to maintain
A solar water heater requires little upkeep. It can be kept in good working order for years with only periodic cleaning. There is little chance of failure or repair because there are no moving parts. Additionally, the price for initial installation is meager, making it the best lengthy self-sustaining water-heating option for the entire family.
Dependence is reduced
Solar energy systems reduce the risk of power outages that could take your entire home. Using a solar water heater, you’d have hot water even if there is no electricity.
Conclusion
Solar water heaters require an initial investment but are always a better option for heating water. The only factor we must keep in mind is the proper selection of solar heaters to reach the appropriate water heating requirements at your home/business.
