In this article we will talk about the devices that are used to generate electrical energy from solar rays, solar panels, but what are solar panels?
What are solar panels
Solar panels are generally confused with solar systems , but they work differently. Unlike solar systems , which are used to produce hot water, photovoltaic panels capture energy from the sun and convert it into electricity.
The electricity generated by photovoltaic panels is most often used to power household appliances and equipment . The most common photovoltaic system is a grid connected system. This means that at night, when the solar panels are not working, you can use the electricity that is returned to the grid during the day.
The second type of solar panel system is a standalone system that is not connected to the grid. In that case, you can add batteries to the system to have electricity when it gets dark. This system can be really convenient in remote areas where there is no alternative to other sources of electricity. Today, thousands of people power their homes and businesses with photovoltaic panels .
Next, you will learn how the panels work, the benefits of using them, and the necessary maintenance.
How do photovoltaic panels work?
Solar panels consist of small solar cells that are connected to each other. Photovoltaic cells are made of semiconductor material, silicon being the most widely used material for this purpose. Cells are usually very small, but when combined into solar panels, they can be very efficient. When the sun’s rays hit cells, an electric field is created. The stronger the sun, the more electricity is produced. However, photovoltaic cells do not need direct sunlight to function and can still produce electricity on a cloudy day.
Photovoltaic panels are available in a variety of shapes and sizes and can be easily mounted on an existing roof.
Benefits provided by photovoltaic panels
Using photovoltaic panels as a source of electricity can be really beneficial. After purchasing solar panels and assuming the installation cost, you can start saving money with reduced electricity costs. In addition to these savings, there is also the opportunity to earn money from solar farms . The law in Poland allows the construction of micro-installations and the production of electricity from renewable sources for natural persons for their own needs and for sale and production in small facilities by entrepreneurs engaged in non-agricultural commercial activities. Another advantage of panels photovoltaic is its respect for the environment. Using them helps reduce our carbon footprint.
Photovoltaic panels and maintenance
Solar panels require little maintenance ; they just need to be kept clean and not under the shade of trees. If dust or snow becomes a problem, clean it with warm water and a brush or high-pressure hose. If you don’t feel like doing it yourself, you can always contact a window cleaning company to get the job done.
Solar panels can last up to 35 years or more, but the inverter needs to be replaced after ten to fifteen years. However, it is always safest to check with your installer to find out what the specific system maintenance requirements are and what is included in the warranty.
The energy Solar photovoltaic is an excellent source of renewable energy and there are many reasons to start reaping the benefits. In addition to reducing your carbon footprint, you will also reduce your electricity bills. Also, solar panels are easy to maintain and will last for a long time.
Currently, in Poland, we can observe a boom in photovoltaic energy, especially in provinces such as: Pomorskie, Wielkopolskie, Mazowieckie, as well as in large cities such as Warsaw, Krakow .
