Solar panels are devices that convert the sun's energy into electricity. The basic elements of solar panels are photovoltaic cells, which use the photon energy of the Sun to generate electrons and generate electric current.
Below we bring you some of the key information about solar panels.
The basic elements of solar panels are photovoltaic cells, which are usually made of silicon. Photovoltaic cells absorb photons from sunlight and create an electrical voltage.
There are different types of solar panels, including monocrystalline, polycrystalline and thin-film panels, each with different characteristics and functions.
When it comes to the efficiency of solar panels, it can vary. Modern panels typically have efficiencies between 15% and 22%. This means that they convert 15% to 20% of the Sun's energy into electricity.
Depending on the amount of electricity that the user wants to produce with the help of solar panels, solar panels are installed in different places, so they can be installed on the roofs of houses or on the ground, with mandatory exposure to direct sunlight. In addition to the panels, inverters must be installed to convert the DC electricity produced by the panels into AC energy used in households.
It is important to say that solar panels are environmentally friendly because they do not produce gases that cause the greenhouse effect and reduce the need for fossil fuels.
Although it does not seem profitable at the start, and the cost of installing solar panels can vary due to several factors, investing in the installation of solar panels in the long term brings great savings on electricity bills and returns on investment.
Many states offer subsidies and incentives for the installation of solar panels to encourage the use of renewable energy sources.
Due to the simple design and durable materials, solar panels require minimal maintenance, which is reflected in the occasional cleaning of impurities that accumulate over time due to various human and weather factors (rain, leaves, smog, soot,...). In normal circumstances, where these influences are not great, cleaning once a year is sufficient, while in conditions of increased influence of human and weather factors, cleaning is required at least twice a year. Especially when it comes to solar panels located near factories.
Most solar panels have a lifespan of 20 to 25 years, but many panels can remain functional for longer than that.
The amount of energy produced by solar panels depends on the location, angle of installation, weather conditions, cleanliness of the panels.
Solar panels are certainly a viable option for generating electricity and are increasingly popular for homes and commercial buildings as a way to reduce dependence on fossil fuels and reduce the cost of electricity bills.
