Three myths about solar panels

Solar energy is still accompanied by a multitude of ambiguities, although solar panels have been producing green kilowatts around the world for decades. When looking for information about this renewable energy source, it is easy to come across incorrect claims or “bad experiences”, although it is important to understand that solar panels can only bother you if they are not installed by professionals.

Installing solar panels can damage the roof

Some may not like the idea of ​​installing solar panels on the roofs of houses because they are afraid of damaging the roof.

Although the construction of a solar power plant requires that the roof be drilled in several places in order to install panel supports, well-trained workers will make sure that not a single drop of water enters your home. Most companies install roofing foils under the tiles to prevent leaks, and many subsequently plug the holes with tar or similar material, Energysage writes.

Also, some fear that the extra weight of the panel will damage or even collapse the roof, although this, experts say, is not a cause for concern. If you hire a licensed company that has a lot of successful projects behind it, a detailed assessment of the roof is one of the first steps they will take before they start building a solar power plant.

Solar panels are not resistant to hail

Although they seem fragile and fragile, solar panels are made to withstand some of the most extreme weather conditions. However, as almost all solar manufacturers use glass as the top surface, the question arises whether the panels have a chance against the city?

That is why the quality of solar panels is measured, among other things, by their resistance to the city, and for that purpose, special tests have been designed that simulate this weather disaster.

The minimum test, which must be passed by every manufacturer of solar panels, involves hitting an ice ball with a diameter of 25 mm in 11 different places on the panel at a speed of 23 meters per second, writes Solar Power World.

This test is easily passed by the manufacturers, which means that almost all panels are resistant to hail of moderate intensity. Yet, as we witness increasingly extreme weather conditions, a city the size of a baseball is a legitimate cause for concern.

Solariums quickly lose efficiency

It is true that solar panels produce less and less electricity over time, although this is something that new power plant owners do not have to worry about. If you have carefully selected the equipment and the contractor, your power plant will be operational for up to 30 years, and the loss of efficiency per year will be only 0.5 percent, writes EcoWatch.

There are other factors that can lead to reduced efficiency of solar panels such as dust, shadow, snow or mechanical damage, but you can mostly influence these factors.

It is important that you hire a licensed company to build a solar power plant and, following their instructions, take care of your solar panels.
