In the context of the climate emergency and the continued rise in energy costs, more and more people are turning to solar energy as a solution to reduce their dependence on the power grid and cut their bills. One option that is gaining popularity is the balcony photovoltaic. This innovative solution allows you to generate energy directly from your balcony, an ideal solution for those living in cities, in apartments, or in buildings without a suitable roof for traditional solar systems. 

In this article, we will explore why choosing a balcony photovoltaic system is a smart, eco-friendly, and economical choice, and we will do so with updated data at hand.


What is a balcony photovoltaic system?

A balcony photovoltaic system is a small solar plant designed to be easily mounted on balconies, terraces, or other outdoor spaces. Unlike traditional photovoltaic systems, which require a large surface area like a roof, the balcony photovoltaic adapts to smaller spaces. Its ease of installation and the fact that it doesn't require complex interventions make it an ideal solution even for those without experience in electrical installations. Thanks to plug-and-play systems, it is enough to connect the system to the power outlet to start producing energy. The most common models have a power output between 400 W and 800 W and are designed for instant self-consumption.


How does a balcony photovoltaic system work?

The balcony photovoltaic system works in a similar way to traditional solar systems, but on a smaller scale:

  1. Solar panels: The photovoltaic panels capture sunlight and convert it into direct current (DC).

  2. Inverter: A micro-inverter converts the direct current into alternating current (AC), the type of electricity needed to power all the electrical devices in the home, from appliances to lighting.

  3. Connection to the grid: The energy produced is fed directly into the home network, powering appliances in real-time. With a 800 W system, for example, up to 1,200 kWh per year can be produced in optimal conditions in sunny areas.


The advantages of balcony photovoltaic systems

A balcony photovoltaic system not only provides a practical and convenient answer to daily energy needs but also brings with it numerous advantages that make it a beneficial long-term choice.


Ease of installation

The main attraction of a balcony photovoltaic system is the ease with which it can be installed. Many balcony photovoltaic systems are plug-and-play, meaning that once the kit is received, you simply mount the panels on the balcony, connect the inverter, and plug it into an electrical outlet to start producing energy. Installation usually takes between 1 and 3 hours. No advanced technical skills or professional intervention are necessary, making this solution very accessible even for those without experience with solar systems.


Energy savings and reduced bills

One of the main reasons to choose a balcony photovoltaic system is the potential for savings on energy bills. An 800 W kit can generate up to 1,200 kWh per year, covering up to 30% of the electricity needs of a typical family, especially if they are home during daylight hours.

The annual savings vary depending on the cost of energy: in Europe, it can reach up to 300 €/year in areas with higher rates. Considering that many kits cost between 300 € and 1,300 €, the payback period for the investment generally occurs in 2–5 years.


Sustainability and reduced environmental impact

A balcony photovoltaic system contributes to a more sustainable future as it uses a renewable and clean energy source: the sun. On average, a kit of 700–800 W prevents the emission of about 200–250 kg of CO₂ every year, effectively contributing to the fight against climate change. It is a simple yet powerful choice to reduce your ecological footprint.


Versatility and adaptability

Balcony photovoltaics are designed to adapt to various balcony configurations, whether they are masonry, with railings, or other structures. There are glass modules sturdy for traditional balconies and flexible modules that adapt to curved or irregular surfaces. This versatility allows maximizing the available space, regardless of the shape or size of the balcony.


Low initial costs and quick payback

Compared to traditional photovoltaic systems, balcony photovoltaics are relatively inexpensive. As mentioned, the initial investment starts at around 300 € for the simplest systems and goes up to 1,300 € for the more complete ones. Installation costs are low, and thanks to energy production for self-consumption, it is possible to recoup the investment in a few years, especially when combined with incentives or tax bonuses.


Glass modules vs flexible modules

When choosing a balcony photovoltaic system, you can opt for glass modules or flexible modules. The choice depends on your needs and the type of balcony on which the system will be mounted.


Glass modules

These panels are more robust and durable. They are ideal for masonry balconies and can be easily adjusted to optimize sunlight reception. They offer high efficiency, especially if oriented correctly during different seasons.


Flexible modules

Flexible modules are lightweight and more adaptable to irregular surfaces. These panels are perfect for balconies with railings or not perfectly flat surfaces, as they can be easily secured without compromising efficiency. They are especially useful for those who want to install a system on smaller balconies or in limited spaces.

Installation guide for a balcony photovoltaic system

The installation of a balcony photovoltaic system is simple, but it requires some precautions to ensure that the system operates correctly and safely:


  1. Choose the right position: The position of the panel is crucial. Make sure that the balcony is exposed to sunlight during peak hours (9:00 AM - 3:00 PM) to maximize energy production.

  2. Mounting the panels: Secure the panels using the provided supports, paying attention to maintain an optimal angle of inclination, which can vary depending on the season.

  3. Connecting the inverter and the grid: Connect the inverter to the photovoltaic panels and plug it into a power outlet or the home network to start using the produced energy.


Why choose a balcony photovoltaic system?

Choosing a balcony photovoltaic system is a smart choice for those who want to produce their energy simply and conveniently without needing large spaces or complex systems. With significant savings on bills, economic returns in a few years, and a positive environmental impact, the balcony photovoltaic system proves to be an ideal solution for self-consumption in urban areas.

The option of choosing between glass or flexible modules allows you to find the right solution for every type of balcony. Start today by utilizing your balcony to produce clean energy, reduce emissions, and lighten your household expenses.
