Solar panel water heater is a water heating system that uses solar as the power. Through a panel (board), the sun ray is absorbed, converted, and then saved as the energy supply. Nowadays, technology using the sun and other natural sources is being enthused. Two main reasons behind it are to reduce the use of fossil-based energy and to reduce gas emissions. From time to time, the emissions are accumulated and become dangerous for the environment.
Emissions pose a significant threat to public health, particularly impacting respiratory health. Additionally, another critical effect of these emissions is their contribution to global climate change. While this change might not be immediately visible, it is indeed occurring. Moreover, it manifests in altered seasonal patterns, with the onset of seasons no longer following traditional timelines. Recently, these environmental shifts have led to more frequent extreme weather events, causing considerable damage in numerous places.

The Reasons for Shifting to Solar Panel Water Heater
The energy source of solar panel water heaters is a sustainable natural thing. It is free and abundant and everyone can access it easily. Besides, it is more eco-friendly. It is also versatile for many needs such as pool heating, telecommunications equipment, and other equipment. The installation might need more money but after that, the homeowners can enjoy the free power that is given by nature.
The gas emission is now becoming a serious issue. So many diseases are caused by this. The huge pollution also blocks the sight. It impedes productivity and somehow endangers those who are on the road. Changing the power source to this sun-powered equipment indeed gives benefits.
Solar Panel Water Heater Calculation
Before deciding to purchase or install anything, you have to consider some prominent things. The most important thing is the financial calculation because it will have a big effect on the homeowner’s life. It is said that the sustainable source is good for both the environment and for the building owners. However, we can’t just install it right away without calculating the cost.
The panel that is responsible for catching the light has various prices. To have enough energy to heat the water, the panels have to reach a certain number. The price of the components then is added to the installation fee. After all has been calculated, compare the result to the monthly bill or previous system. It is to know how long you will get the payback.
Don’t forget to think about another factor that will decide the success of this system such as the climate. In certain climates is hard to use this system, so, make sure that your area doesn’t have that climate. One more consideration is the other systems. Compare to other systems to make a perfect comparison. After that, deciding is easy because you have a clear estimation.
Is Your Home Okay for Solar Panel Water Heater Installation?
The homeowners cannot just say yes to the installation immediately. Firstly, it is a big decision and will require a lot to consider. Unlike purchasing a vacuum cleaner or other small equipment, installing a solar panel water heater is a more significant undertaking. Most importantly, the suitability of the building plays a crucial role. Therefore, before making a decision, homeowners should carefully evaluate whether their building is appropriate for such an installation.
The Roof Width
The roof serves as the primary location for the solar panels, acting as the initial receivers of sunlight. Generally, it requires approximately 2 to 5 square meters of space. In this case, the larger the area, the better, because a more extensive surface area will catch more rays, enhancing the system’s efficiency.
The Building Around the House
If there are a lot of tall buildings or big trees that block the sunlight, the system will not work. Make sure that the top of your house can be easily exposed to daylight.
The Direction the Roof is Facing
If the roof is facing east, it will be exposed to the sun only from the morning to the middle of the day. If it is facing west, it will get sunlight in the afternoon until nightfall. To get the longest duration of sun exposure, the roof should be facing south, south-west and southeast. The ideal one is exactly southward, but the two others still get a long time of sun exposure.
Some permanent factors can’t be changed. However, the direction the roof is facing still can be modified. It needs renovation, but back to the calculation, if you urgently need the solar system, it can be planned.
Conclusion
Solar panel water heater is a sustainable and eco-friendly technology. It helps the earth to become ‘healthier,’ contributing positively to environmental well-being. Furthermore, this approach is beneficial for both humans and the environment, leading to mutually advantageous outcomes. Additionally, it significantly reduces our dependence on fossil-based fuels, a resource that has seen a recent decline in availability. However, it needs some requirements for installation to maximize the system work. The requirements are the minimum roof width is approximately 2 to 5 square meters, the home area is clear from the sun barrier, and the roof should face south, southeast, southwest.
In addition to the numerous benefits of solar panel water heaters for conventional water heating purposes, an increasingly popular application is their integration with underfloor heating systems. Underfloor heating provides a comfortable, even warmth distributed across a room, and when powered by solar water heaters, it becomes an extremely energy-efficient solution. The solar panel water heater can transfer heat to a water-based underfloor heating system, creating a synergy that maximizes the use of renewable energy.
This combination not only further reduces dependence on fossil fuels but also enhances the overall efficiency and comfort of the home’s heating system. By utilizing the consistent and sustainable energy from the sun, homeowners can enjoy a warm, comfortable living space with significantly lower energy costs and a reduced carbon footprint. However, it’s important to consult with a professional to assess the compatibility and sizing requirements of the solar water heater and underfloor heating system, ensuring optimal performance and efficiency.
So, should you opt for a solar panel water heater? It’s a decision that offers environmental benefits, potential cost savings, and now, with the added possibility of integrating with underfloor heating, increased home comfort and efficiency.
