SalvaTerra: Planter with Vertical Corten Steel Solar Panels

Each SalvaTerra module incorporates two panels with a total peak power output of approximately 880–900 W. Over the course of a year, depending on sunlight exposure, it can generate several hundred kWh of clean energy. This output is sufficient to continuously power small appliances (e.g., outdoor garden lighting, a fountain pump, a Wi-Fi router) or to contribute to a home’s overall electricity needs, thereby reducing the utility bill. In commercial settings, multiple planters installed in series can generate tens of thousands of kWh per year, covering, for example, all the nighttime lighting for a hotel park or an urban plaza. Actual output depends on the climate zone and how the energy is used (immediate self-consumption or feeding into the grid). Thanks to its bifacial panels, SalvaTerra guarantees excellent performance even in less-than-ideal conditions (east-west orientation, partial shade, winter), maximizing output compared to traditional solar solutions.

Generally speaking, no. Generally speaking, no. The SalvaTerra Photovoltaic Planter is designed to be a movable piece of furniture; therefore, it is a photovoltaic system that does not require permits in private settings, so it does not require building permits. Installing it in your garden, courtyard, or terrace is like placing a large planter or a lightweight pergola: since it is not permanently anchored to the ground nor does it alter the building’s profile, it does not fall under the category of projects requiring a building permit. If, however, you wish to place it in a common area of a condominium, a condominium resolution would be required, just as it is for any furnishings in common areas. For installations in public spaces, a permit for the use of public space must be obtained, just as for temporary street furniture; since it is a non-permanent structure, this is typically a straightforward process. Finally, in areas subject to landscape restrictions, the Superintendents’ Offices tend to view solutions like SalvaTerra favorably because they are reversible and have a low visual impact, making them easier to approve than rooftop panels.

Yes, SalvaTerra is designed to withstand the elements and requires very little maintenance. The Corten steel structure is extremely sturdy: it withstands rain, snow, strong winds, and UV rays without warping or deteriorating. The protective patina that forms on Corten steel makes it virtually immune to through-corrosion, even in salty or humid environments. The solar panels feature tempered, hail-resistant glass and a sealed frame: they are built to withstand outdoor conditions 365 days a year, just like any solar module used in rooftop systems. All electrical components (inverters, wiring) are securely housed and insulated, thus protected from rain and dust.

As for maintenance, it’s minimal. Regarding the system itself: it’s advisable to clean the surface of the panels perhaps 2–3 times a year (a soft cloth and water are sufficient—no harsh detergents needed) to remove any dirt and ensure maximum efficiency. That’s it: there are no internal filters, motors, or batteries to check or replace. As for the planter and plants: care for the plants just as you would in a regular planter—water them, prune as needed, and replace any seasonal plants—according to the needs of the specific plants you’ve chosen. Corten steel should not be painted or treated (don’t even think about it! Its beauty lies precisely in its natural patina). In short, a quick wipe-down of the panels every now and then and regular gardening are all you need: for the rest, you can enjoy free solar energy without worrying about any special maintenance.

Absolutely. Tourism and hospitality businesses that invest in sustainability have access to various incentives and dedicated grant programs. For example, there are PNRR grants (administered by the Ministry of Tourism) that provide up to 80% in non-repayable funding for “green” initiatives in hotels, agritourism properties, and beach resorts—such as the installation of solar panels and innovative street furniture. Many regions also issue periodic calls for proposals to fund energy efficiency improvements in hotels and B&Bs, often through non-repayable grants or low-interest loans. Although these programs change over time, the direction is clear: investing in renewable energy and sustainability pays off twice for hotels, because in addition to savings, they receive financial assistance. Installing SalvaTerra can also help indirectly: for example, it contributes to increasing the score needed to obtain environmental certifications (such as GSTC or LEED) or eco-labels in tourism, and some regional calls for proposals award extra points in funding to facilities that include such solutions in their projects. In any case, hotels are advised to check with their trade association or an energy consultant to see which measures are currently in effect; however, in general, there is broad public support for those who embrace sustainable innovation like SalvaTerra.

Yes, private individuals can take advantage of the 50% tax deduction provided for under the Renovation Bonus (Art. 16-bis of the TUIR) for the installation of photovoltaic systems in residential properties. The SalvaTerra planter qualifies for this tax benefit because it constitutes a renewable energy production system for domestic use. In practice, half of the cost incurred (including VAT and installation) is refunded to the owner in the form of IRPEF tax deductions in 10 equal annual installments. For example, on a total expenditure of €10,000, you’ll recover €5,000 over ten years (€500 per year in tax relief). You must verify that your property has sufficient tax capacity and that the work is carried out in compliance with regulations. In summary, through the end of 2025, as a private individual, you can deduct 50% of the cost of the SalvaTerra project, effectively halving the out-of-pocket expense thanks to government incentive programs for solar power. At the end of the year, these percentages may change depending on the budget bill.
