As solar panel technology continues to improve, an increasing number of businesses and homeowners are making the switch to solar energy. But with this increased demand comes the need for rigorous testing to ensure that solar panels withstand all sorts of weather conditions and hazards.
Solar panels are being tested in several different ways to see how they hold up against the elements. In this article, we will take a look at some of the most important solar panel tests and what they mean.
HOT SPOT PROTECTION
One of the most important solar panel tests is hot spot protection.
According to an article written by q-cells.eu hot spots are created, ”During different production steps, the primary material of solar cells – the silicon wafers – are subject to both chemicals and severe heat of up to 900 ℃. They are also put under mechanical stress during transport. Together these factors can lead to very small material defects – so-called “micro cracks” – that cannot be seen during conventional final inspections. Defective edge insulation can also cause hot-spots.”
If a hot spot occurs, it can cause the solar panel to overheat, become less efficient and potentially catch fire. Solar panels are placed in a chamber that simulates intense sunlight to test for hot spot protection. The panel is then monitored to see how well it handles the heat.
Another important solar panel test is hail damage. As the name suggests, this test is designed to see how well solar panels can withstand being hit by hail. To do this, solar panels are placed in a chamber and then bombarded with hailstones of various sizes. Then, the panel is monitored to see if any damage occurs.
PERFORMANCE & EFFICIENCY
Solar panel performance & efficiency is another important aspect that is tested. This includes solar panel conversion efficiency, which is the percentage of sunlight that the solar panel can convert into electricity. Solar panels with a higher conversion efficiency are more effective at generating electricity.
To test solar panel performance, solar panels are placed in a device called a solar simulator. This simulates different conditions that the solar panel might encounter, such as changes in the angle of the sun or cloud cover.
The solar panel‘s output is then measured to see how well it performs.
Overall, these solar panel tests are essential in ensuring that solar panels can withstand all sorts of weather conditions and hazards. In addition, by doing these tests, we can be sure that solar panels will be able to provide us with clean, renewable energy for years to come.
