Deciding on using solar panels as the source of energy for your house is not easy. It is costly, time-consuming and it may not provide as much power as other exhaustible energy sources. Further, solar panels tend to be less efficient over time, and it is also prone to damage or breaking. For that reason, you will need solar panels that you can rely on, and the experts recommend to conduct the following steps to determine your solar panel’s reliability. Euro Solar Group is one of the providers of excellent quality solar panels. If you are concerned about getting solar panels for your house, make sure to read about them.
1. Know The Types
It is important to learn about different types of solar panels before making the decision to install it for your house. The most used solar panels nowadays come from three distinct groups, namely monocrystalline solar panels, polycrystalline solar panels, and thin film solar panels.
MonoCrystalline Solar Panels
Monocrystalline solar panels are usually black in colour, and its cells corners are absent due to its unique production process and physical nature. The process is very similar to semi conductor’s production, where silicon dioxide put into an electric arc furnace. The most efficient monocrystalline solar panels can yield up to 22.5 percent efficiency level, and in theory, it cannot use for light–energy conversion higher than 29 percent. There are a lot of reasons why monocrystalline panels are relatively preferred more than other types of solar panels. Known for its long life and durability, some even claim that monocrystalline solar panels can last for about 50 years. Despite this fact, most warranties for monocrystalline solar panels last for 25 years with various terms and conditions. Monocrystalline panels can also resist heat better, and as a result, it will produce more electricity in higher temperature when other materials suffer a reduction in their electricity output.
Polycrystalline Solar Panels
The most attractive feature of polycrystalline solar panels compared to monocrystalline would be its price. Polycrystalline is cheaper than monocrystalline only because the silicon melted into a cast instead of being shaped as single crystals. The process of making polycrystalline solar panels itself is easier because liquid silicon will be put in a graphite mould to create a silicon block. However, polycrystalline solar panel’s efficiency is lesser compared to monocrystalline solar panels. It has lower heat tolerance compared to monocrystalline solar panels, and it requires a larger surface to be able to produce the same electrical output generated by a smaller monocrystalline solar panel.
Thin Film Solar Panels
Thin amorphous solar panels are made from non-crystalline silicon, while Thin Film solar panels can make from cadmium telluride or copper indium diselenide. The amorphous solar panels are considered to be similar to other thin film solar panels due to its silicon wafer form. Thin film solar panels are famous for its flexibility. They can apply to various types of surfaces with different shapes and curves, where crystal silicon solar panels are very rigid and fragile.
2. Consider the Financial Partiality
Reliability does not always refer to the performance and output of the solar panel. Financial bias can also be taken into account when determining your solar panel’s reliability since it will significantly affect whether or not the produced electricity will balance out the expenses paid. A solar panel can be of different sizes, where for example 180 up to 220 Watt solar panel will be of the same size. On that note, the monocrystalline solar panel is the most expensive type amongst the three, but the possibility of getting a bank financing for it is much higher compared to the other two varieties due to its durability and long-life. Moreover, fragility should also be considered concerning the expenses, because you will need to set sufficient insurance for any damage or replacement. Fragility could be something to think if you live in an area with strong wind or frequent storm, as solar panels can get damaged by objects carried by a strong wind or storm. Polycrystalline solar panels are known to be the most fragile, where they can be severely damaged when hit by a branch or other objects being carried by a strong wind.
3. Install and Maintain Correctly
Once you have decided on a particular solar panel type, make sure that it is install suitably. For example, thin film solar panels do not work well on roofs that face south, however; it can survive through high heat without suffering a decrease in output. However, thin film solar panels yield greater output in places with hot climates and higher temperatures, with occasional cloudy weather to provide partial shading for the panels.
Conversely, crystal solar panels are environment-friendly compared to non-crystal thin film solar panels and hence they require a less complicated method of recycling or disposal. Thin film solar panels especially the cadmium telluride type are considered as a probable carcinogen for human beings, and hence they need to be disposed of in a unique manner as a toxic waste in a particular specialised waste management facility. Nevertheless, monocrystalline solar panels are more sensitive to shade, dirt or snow and hence they must clean continuously. Dust and shades will reduce the monocrystalline solar panel’s efficiency, and this may cause unnecessary and time-consuming extra duty. As a conclusion, choose other types of solar panels if it 's hard to do the cleaning regularly.
4. More Points to Consider
Aside from the three pieces of advice mentioned above, there may also be other parameters that can be used to measure solar panel’s reliability. For example, weather impact on the electrical output as well as its aesthetic value especially if integrated into a building’s space and overall design. These aspects closely link to climate conditions and geographical locations. On top of that, the manufacturer’s reputation of solar panels, as well as the manufacturing process and the materials used for the process, are also important to determine its reliability. As a conclusion, list down everything before purchasing your solar panel and make sure that it is reliable.
