Facts About Photovoltaic (PV Komplettanlage) Solar Panels
We can all agree that green energy is becoming more popular than before. Hence, people started using solar as the best environment-friendly option for generating clean power and saving money on bills.
A solar panel is a group of electrically connected solar cells that use photovoltaic technology within a frame that directly converts a percentage of sunlight into energy. Remember that switching to solar power comes with numerous benefits, including saving money while helping the environment.
However, it comes with certain disadvantages or limitations depending on the weather conditions, household position, and price tag. It is vital to learn other essential facts that will help you determine whether you should invest in panels or not. Let us start from the beginning.
Things to Know About Solar Energy
You should know that Leonardo da Vinci created an idea and predicted in the 15th century that we would harness the sun’s energy and use it for our daily requirements. However, scientists developed the first solar cell in the 19th century, but it had one percent efficiency.
As soon as you deal with initial expenses, including panel costs, you do not have to spend another cent on the electricity you produce. At the same time, you will reduce your carbon footprint because solar energy is renewable and green compared with other options.
According to statistics, users save more than seventy-five million barrels of oil and thirty-five million tonnes of carbon dioxide. At the same time, you can harness plenty of power from the sun. For instance, the Earth receives more energy in a single hour than the entire world can consume in one year, but the panels are not efficient enough to handle that amount.
They feature photovoltaic cells (PV Komplettanlage), which we call solar cells. Remember that they feature silicon as a semiconductor that converts sunlight into electricity. As soon as light enters the cell, the electrons will separate and flow throughout the cell, which will generate power as a result.
Today, you can find options for household installation and properties that can convert up to twenty percent of light into electricity. Some commercial systems can go up to forty percent of solar efficiency. Still, the technology is continually advancing, meaning solar efficiency will grow accordingly, while the initial expense will drop.
When it comes to initial expenses, you should consider the installation cost. Although the prices can be high at first, you will get a short breakeven or payback period, mainly because you will save on government aid and electricity bills. Households with solar energy can sell faster and have higher curb appeal and value than those without.
At the same time, advancements in technology and increased demands will decrease prices due to lower materials costs and economies of scale. The facts are that prices have continually fallen since the introduction, meaning you can rest assured along the way.
As soon as you install it, you can rest assured because they do not require maintenance as other options. Of course, you must make sure they are clean and without obstructions, making them less efficient. Suppose you have a tilted roof. In that case, you do not have to clean it as much because rain will remove excess dirt.
Remember that they are highly durable, meaning you will get a twenty-five-year warranty, but the process can last up to forty years. It is vital to remember that you will get max efficiency when the sun is shining directly. You can also get it during winter and electricity. On the other hand, you cannot produce it overnight, but you can find storage systems that will help you.
Generally, solar battery storage is an effective way to use excess energy and make yourself 100% energy-dependent. Although you will need panels that produce free electricity throughout the day, having storage will help you use it during the night and on cloudy days when you cannot achieve the same efficiency.
Things to Consider First
Before installing them, you should consider the inclination and shape of your roof and the house’s location. If you wish to achieve the best performance, the top should face a thirty-degree angle. Of course, we are not stating requirements, mainly because they can operate in numerous settings, but you should install them in areas without shadows and obstructions.
It is vital to keep them far from trees and bushes for two fundamental reasons: they may shade the installation and reduce efficiency during peak hours, while leaves and branches may scratch the surface, causing damage in the long run.
Continual rain and wind exposure can degrade performance, so you should protect it against winds during placement. Still, they are highly durable, meaning they come with 25-year warranties, meaning you will get a guarantee that they will not fall below eighty percent efficiency during this period.
At the same time, panels do not operate appropriately in too hot climates, which is contrary to belief. The main reason for that is that cells harness sunlight, meaning high temperatures can affect their efficiency.
