Factors to Keep in Mind While Choosing Solar Panelsby Simon Morris I am a freelance writer.
A solar panel system is supposed to be an effective inter-connected assembly or array of photovoltaic solar cells known for capturing the energy released from the sun as photons and then transforming the solar energy straightaway into electricity. The exact amount of electricity generated in watts or volts would vary as per the system and the specific kind of solar cell. Let us explore some critical factors to consider before choosing the best solar panels for your home, business or commercial use.
Examine the Solar Panel Efficiency
The efficiency of solar panels is measured in terms of the ratio of the power or energy present in the sunlight which would be hitting the panel surface directly to the electrical energy that is produced by the module. For instance, if the solar panel could capture half the sunlight’s energy, the module efficiency in such a case would be 50 percent. In real-world situations, traditional panel efficiencies would be ranging from roughly 12 percent to a little more than 21 percent. The high efficiency of solar panels is supposed to be good. Higher efficiency implies increased watts of electricity / sq. the meter of a solar panel. Hence, with higher efficiency, the solar panel would become smaller requiring less roof space and offering the same electrical output. However, high-efficiency panels would be costing more. Remember that your solar panel efficiency must exceed 15 percent at least. Choose a solar system Brisbane, with solar panels of high efficiency.
Determine the Quality of a PV Module
The quality of solar PV panels isn't easy to gauge right away from the price stated since sales folks are always a bit biased. The most important thing to do when you come across a particular product is to seek out reviews from Australian customers over the years. A large customer base is a good start because it will give you an idea of how well the panels hold up and perform in several areas and local conditions. You should also look at reviews that are posted after the owner has gotten a few months of use out of it, to eliminate recency bias and give things some time to stabilize. You should also scour the internet for comparison charts and videos of popular solar panel offerings so you can understand what kind of modules are available to you and what kind of value you get for your money.
Check Out the Warranty
Another the big thing you need to look into is the warranty offered by the manufacturer, the terms of the statement and how well the product conforms to quality standards and maintenance and support benchmarks. You will need to take a deep dive into the fine print to figure out if there are any catches in terms of things they might not cover under the warranty, as well as certain issues for which you would have to send your modules back to them.
Look into whether the company adheres to national and international quality standards and is approved for sale in Australia. You should also have enough assurance that the company will be around in 10-15 years when you might need a good service to be performed. A 10-year manufacturer warranty is an absolute necessity and you shouldn't be fooled by marketing terms like a “30-year performance guarantee” since they are far from the same thing as a warranty and mostly just empty assurances.
After considering the above factors, you could consider the overall aesthetics of the solar panels. Choose solar panels as per your preference. You could consider thin-film panels since they look sleek and pretty uniform. Some panels look bulky because of their lower conversion efficiency.
