In recent years, Solar Photovoltaic Energy has gained increasing popularity as a Renewable Energy Source. One of the most accessible ways to take advantage of this technology is through the installation of a Balcony Photovoltaic System. However, it is important to underline that this option has some limitations compared to installing a traditional Photovoltaic System on the roof of the house.
What are Balcony Photovoltaic Panels?
Balcony Photovoltaic Panels, or Balcony Photovoltaic Systems, are compact systems that allow you to generate solar energy on a small scale. These devices are designed to be installed on balconies or building facades and use sunlight to convert it into usable electricity.
For those who live in a condominium, Balcony Photovoltaics can represent an interesting solution when it is not possible to install a traditional system on the roof. In fact, if all condominiums agreed, solar panels on the roof would be very advantageous for the energy production of the entire building. Often, however, it is difficult to find an agreement, and the simplest solution that allows individuals to exploit solar energy independently is to install a photovoltaic system on the balcony.
Unlike traditional photovoltaic systems, balcony photovoltaic panels, by law, cannot have storage systems. This means that it is impossible to select a photovoltaic panel with storage to meet your needs and the excess energy produced by balcony kits cannot be stored for use at a later time, for example during the night hours.
Furthermore, by choosing to install balcony photovoltaics without storage, you must give up the possibility of taking advantage of the on-site exchange and dedicated collection agreements. This means that the energy produced by balcony photovoltaic systems is only used to support immediate energy consumption, without the possibility of storing or selling excess energy.
The possibility of receiving remuneration for the excess energy that is reintroduced into the electricity grid is instead guaranteed by traditional photovoltaic systems.
Balcony Photovoltaic: How Does it Work?
How Does a Balcony Photovoltaic Panel Work? The Balcony Photovoltaic System is mainly composed of solar panels which, in turn, are made up of silicon photovoltaic cells, capable of capturing the photons of sunlight and transforming them into electricity through the phenomenon of the photovoltaic effect.
This energy is then converted into Direct Current (DC) and can be used directly to electric power household appliances or charge electronic devices via an inverter, which converts the direct current into Alternating Current (AC) compatible with home use.
Before considering the purchase of a Photovoltaic Panel for a Balcony, it is a good idea to evaluate all the advantages and disadvantages resulting from the installation of these devices. One of the most obvious advantages concerns the “Plug and Play” system, a peculiarity of balcony photovoltaic panels. The latter is designed to be easy to install so that even users without specific technical skills can assemble them independently.
Therefore, to be able to take advantage of the energy generated by plug-and-play balcony photovoltaic panels, simply connect them directly to a domestic power socket, making the connection of the system extremely simple and immediate.
Therefore, it is important to keep in mind that balcony photovoltaic panels are standard products, but advantageous due to their ease of installation by the buyer, without requiring the intervention of a specialized technician. The possible disadvantages linked to the purchase of these devices emerge with the comparison with traditional systems.
A Photovoltaic System installed on the roof of the house, i.e. a traditional system, offers a much greater capacity than a balcony photovoltaic system. This is because the roof system is custom-designed, makes the most of the ideal southern exposure, and reduces any shading to a minimum.
The average size of rooftop systems varies from 4kW to 9kW, while Balcony Photovoltaic Systems reach a maximum of 1kW. Consequently, while a traditional system, combined with a storage system, can guarantee up to 75% savings on the electricity bill, a balcony kit can reach a maximum of 20%.
Another important consideration concerns the lifespan of traditional photovoltaic systems, which is estimated on average to be around 20 years. These systems can not only reduce energy costs, but also increase the value of the property, positively influencing its energy class, and improving it by one or two classes. In contrast, balcony photovoltaic panels do not offer these long-term benefits. However, they are much more affordable than the costs of traditional systems.
How Much Does a Photovoltaic Balcony Panel Cost
The Cost of Balcony Photovoltaic Panels can vary based on the power of the system, the brand, the quality of the components, and the specific characteristics of the product. However, in general, balcony photovoltaic panels are considered a more economical solution than traditional photovoltaic systems installed on the roofs of houses. The cost of balcony photovoltaics can vary from 700 to 2500 euros, depending on the specifications of the kit.
It is important to note that the cost of balcony photovoltaics is usually lower than traditional systems because the energy production capacity is limited compared to a rooftop system. Balcony photovoltaics have a maximum capacity of usually less than 1 kW, while traditional systems can reach capacities of several tens of kW. Therefore, the price of the balcony photovoltaic system is influenced by the size and performance of the system.
In conclusion, it can be said that a balcony photovoltaic system is advisable only if there are no valid alternatives. For example, it may be an appropriate choice when you do not have a roof on your own property or the necessary requirements in terms of space, structure, and exposure.
Furthermore, it can be an interesting solution for those who prefer to avoid the initial investment required by a traditional system or need an easily removable solution, as in the case of a rented house.
However, it is important to carefully consider the limitations and lower performance of this option compared to traditional photovoltaic systems, in order to make an informed decision on choosing the option best suited to your needs.
