With regards to solar panel installation, the primary objective is to deliver maximum energy from the little space that you can afford. That is the reason high-efficiency solar panels flourish in the current market. They’re especially useful when your rooftop space is quite restricted. While conventional solar panels normally have 16 to 17% efficiency, modules tagged as “high-efficiency” are usually 19% effective. Numerous brands are currently driving their modules to a higher efficiency level of 22% or even better. The Advantages of High–Efficiency Solar Panels The primary advantage of higher-efficiency modules is a more dependable power output. Effective cells generate more power over an extended period of time. The newer techniques solar manufacturers use in developing their product results to very reliable solar panels with higher efficiency levels. However, increased power output and higher efficiency likewise mean costly solar panels. But that shouldn’t be one’s concern. After all, the higher efficiency modules can lead to great saving in the long run. Solar panel modules that deliver more power per square-meter require lower installation and maintenance cost simply because it requires fewer components. The Cost of High-Efficiency Solar Panels The cost of a solar panel depends on its power density. Other costs, such as labor, inverters, and land or roof area should be considered as well. It is more feasible to install highly efficient solar panels.” Solar panel installers increment efficiency in various ways. The mere idea of removing bus bars or ribbon interconnections can go a long way. By placing the cells closer together, inactive space is reduced, thus increasing power and efficiency. Other techniques include utilizing the back-contact technology that places every electrical contact on the back of the cell to make more space on the front to collect more energy. The use of smaller solar cells also effectively increases capacity without expanding the area. Smaller cells are also less susceptible to microcracks that affect output over time. On Choosing High-Efficiency Solar Panels But while high-efficiency modules are so good, there are still a lot of people that rather use the lower efficiency options. Though generally speaking, there are ones that have the luxury of space that they don’t need to spend extra for the same power output. However, high-efficiency modules are still best for users with limited space to work with. Additionally, high-efficiency panels are also preferred by people who have issues with shading, obstructions, and slanted roofs. In all these cases, high-efficiency solar panels prove to work best. Solar panels usually deteriorate after 10 years of use. While manufacturers may offer a 25-year warranty, they may not be around for that long. High-efficiency modules offer better performance and less deterioration. They are expected to produce more power for a long time. So when you’re choosing solar panels, don’t just check the wattage. You may also want to take a look at its efficiency rating. There are several solar packages in Perth that you can check out. Choose wisely when shopping for solar panels and always seek an expert if you have questions about it.
