Innovations in photovoltaic: what changes in 2025 and why it is worth updating

Technology in the photovoltaic sector is advancing at a very rapid pace. The systems installed even ten years ago can now be considered obsolete: new materials, new solutions and new approaches have raised the bar in terms of efficiency, size and cost.

This progress is the result of increasing investments in research, with the aim of developing increasingly performing, small and accessible modules. But not only that: components such as inverters, connectors, smart monitoring systems and especially storage batteries are also benefiting from technological innovation.

The evolution of batteries: less costs, more efficiency

One of the most significant changes concerns precisely the storage systems. Since 2010, the cost of batteries has fallen by about 90%, with forecasts that indicate further declines in the coming years.

In addition to the reduction in prices, the chemical composition of batteries is also changing: today we are focusing on cheaper and more sustainable alternatives to classic lithium, such as sodium ions, the aluminum ions And the magnesium.

Solar panels: increasing efficiency thanks to new materials

Even photovoltaic cells are experiencing a small revolution. The most promising innovation is represented by perovskite tandem solar cells, which combined with silicon make it possible to exploit different wavelengths of sunlight and obtain previously unthinkable efficiencies.

This technology, still being refined, could soon surpass traditional silicon panels, increasing the amount of energy generated at the same surface area and reducing costs thanks to economies of scale.

Another important innovation are the bifacial cells, capable of capturing light from both sides of the panel. According to forecasts, this technology will surpass single-sided technology in terms of diffusion already by 2025.

Less loss, more energy: black silicon

Another frontier of innovation concerns the reduction of optical losses, or the part of energy that is “lost” during the absorption or conversion of light into electricity. To solve this problem, we are focusing on nanostructured silicon — also known as Black silicon — which better absorbs light on different wavelengths and minimizes surface reflectance.

The result? Higher overall efficiency and more energy produced under equal conditions.

Balcony photovoltaic: small spaces, big ideas

The democratization of photovoltaic also involves more accessible solutions, such as plug-and-play systems for balconies. These mini plants allow even those who live in apartments to start producing renewable energy, without the need for complex authorizations or invasive work.

The risk of falling behind (and how to avoid it)

Installing a photovoltaic system today may seem like a far-sighted choice, but with such rapid technological evolution, the risk is that of buying an already “old” technology. After a few years, you may find yourself with an outdated, less efficient and difficult to upgrade system.

For this reason, it is worth considering more flexible and shared solutions, like the one proposed by GridShare.

GridShare: shared photovoltaic, always up to date

GridShare offers an innovative solution: shared solar parks. In practice, instead of installing a photovoltaic system at home, it is possible to purchase a share of a shared system, located in an area with high solar exposure, designed and managed directly by GridShare.

How it works

• You buy a share: the user chooses how much energy to “reserve”, by purchasing a part of the system.
• The plant produces energy: once active, the energy produced is sold to the electricity grid.
• The proceeds are distributed: the revenues obtained from the sale of energy are redistributed proportionately among all participants.

All of this without worrying about installation, maintenance or technological updates. In fact, GridShare guarantees maximum efficiency of the system over time, updating it when necessary.

Why is it convenient

• There is no risk of being left behind: the systems are updated with the latest available technologies.
• You participate in the energy transition without complications.
• You can start with a small investment thanks to crowdfunding, making the project accessible to anyone.

A sustainable investment, also for the future

GridShare represents a concrete alternative to domestic photovoltaic, with the advantage of not having to manage anything personally and still participating in the current energy revolution.

It is a project designed to last over time, which combines savings on the bill, affordability and positive environmental impact. And with the speed with which the sector evolves, it could be the smartest choice for those who want to produce energy in a sustainable way, without risking being left behind.
