Almost everyone has heard of photovoltaic power, but do you all know exactly what photovoltaic panels consist of and what benefits they can bring? People considering buying PV panels often ask themselves if installing them is still worth it. With these questions in mind, we have created this complete guide to buying solar panels. It will certainly bring you closer to PV panels and remove your doubts! This guide is divided into two parts, and this is the first part.
Photovoltaic panels: What is it and how does it work?
To invest in a photovoltaic system or renewable energy, first we should understand what it is and how it works.
The job of a photovoltaic panel is to collect the energy from the sun and generate electricity. Mainstream photovoltaic panels are made from silicon-based semiconductor materials, and by preparing PN junctions, these materials undergo a “photovoltaic effect” when exposed to sunlight, which generates direct current. This direct current is then converted by a device called an inverter into the kind of alternating current that flows in an electrical outlet. Some of it is used immediately, while the rest is fed back into the grid or stored in a battery, from where the current can be used again at a later time.
In short, this is how a photovoltaic system works. Thus, home photovoltaic panels support the process of generating electricity from an inexhaustible source of free energy – solar radiation. Thus, those who have installed PV installations are able to produce their own green electricity and save money in doing so.
Types of photovoltaic panels
There are many manufacturers on the market and they offer different photovoltaic products. Therefore, it is worth knowing which PV panel should be chosen, how they differ and what are their advantages. Two types of panels are usually mentioned.
Monocrystalline panels
The first type of panels are monocrystalline panels, made of single crystal silicon. They provide the free flow of electrons followed by their high efficiency. They are characterized by their dark blue color, almost black. As for the price, it is usually higher compared to other types of panels.
Polycrystalline Silicon Panels
Polycrystalline photovoltaic panels, as the name suggests, are made of polycrystalline silicon, which gives them an intense blue color. This type of panel is slightly less efficient, followed by a lower price. Many people are keen on this type of panel because they have a high yield in areas with low sunlight, which is an extremely important advantage.
Amorphous Silicon Panels
There is a third type. These are amorphous silicon panels, also known as thin-film panels. Many people do not choose them because of their low efficiency. However, if you want to install a PV system on a property that is exposed to high temperatures, consider this type of panel.
It is worth reminding that balcony PV panels are also available. Many people have installed these thin-film panels on their terraces and fences, which make their balconies both look beautiful and produce a portion of free electricity.
How much does it cost to install a home photovoltaic system?
This is one of the most frequently asked questions people ask. First, the cost of photovoltaic power generation is quoted in kWp (kilowatt installed capacity). Therefore, it all depends on the size of the photovoltaic installation. In Europe, taking a 160-square-meter residential house as an example, installing a 5kw grid-connected photovoltaic system requires an initial investment of about 6,000-8,000 euros (tax included).
System installation costs depend on: the capacity of the PV system, the needs of the home, the type of panels, the experience of the installing company or the amount of the subsidy.
By the way, subsidies for photovoltaic panels are something anyone planning to install a photovoltaic system should consider. This will certainly reduce the overall cost of investment. It is worth considering exactly what conditions need to be met in order to qualify for the subsidy. You can consult the relevant policies with the local administrative department.
Where to buy photovoltaic panels?
Now, we already know what types of photovoltaic panels there are. It’s more important to remember that they should be high quality, good brand, and last 25 years.
High quality solar panels can be purchased from Maysun Solar. This company has been thriving in the photovoltaic industry for more than 14 years. For Maysun, the most important thing is the customers and their satisfaction.
The company works hard every day to ensure that the products on offer are of the highest level – whether before, during or after the sale. When looking for a photovoltaic module manufacturer, trust Maysun Solar.
