Bills 30% lighter with one system balcony photovoltaic.
Plug and play photovoltaic represents an interesting solution for reducing domestic energy costs, especially for those who live in apartments, and constitutes an important step towards the energy transition.
It is now possible to find solar panels of different productions and powers on the market. Let’s say we have decided to install balcony solar panels that generate, in optimal conditions, around 400 kWh per year each.
Considering an average annual expenditure of €650 for energy bills, with an energy cost of €0.20/kWh, you could save €80 per year per panel, therefore up to €160 per year for a couple.
The installation of a balcony photovoltaic kit can cost between €400 and €1,200 (depending on the number of solar panels or the presence of storage batteries). Assuming an initial investment of €800 and annual savings of €160, the investment could be paid back in 5 years.
Added to this is the possibility of taking advantage of the deduction bonus which, despite some critical issues identified with respect to this new maneuver, still represents a useful tool to further lighten the initial costs.
Many countries in Europe are embracing the home photovoltaic philosophy. In Germany, the panels have already been installed on around 1.5 million balconies, to the point that the term Balkoncraftwerk (balcony power station). Even in Spain, where two-thirds of the population lives in apartments and the installation of roof panels requires the consent of the majority of condominiums, do-it-yourself technology is gaining widespread acceptance.
In addition to the economic benefits, this technology supports the energy transition towards a more decentralized model, reducing dependence on large energy companies. Challenges remain in regulation and integration with other renewables, but the potential to make cities more self-sufficient is significant.
