Can SalvaTerra operate without being connected to the electricity grid?<span aria-hidden=\"true\">+<\/span><\/summary>\n<div class=\"approved-reading faq-answer\">\n<p><strong>Yes, an off-grid photovoltaic configuration can be designed<\/strong>to power specific loads even where the electricity grid is unavailable.<\/p>\n<p>This requires a battery storage system, an inverter suitable for standalone operation, and management and protection devices sized for the expected consumption.<\/p>\n<p>ETWAY is developing this type of application through the <strong>SalvaTerra Survival<\/strong>project, also designed for remote locations, natural areas and outdoor services without a grid connection. Not all available SalvaTerra configurations are automatically suitable for off-grid operation.<\/p>\n<\/div>\n<nav class=\"faq-related\" aria-label=\"Read more about answer 1\"><a href=\"https:\/\/etway.it\/en\/?page_id=11381\">Discover Survival<\/a><\/nav>\n<\/details>\n<details id=\"faq-2\">\n<summary>2. Can vertical photovoltaics increase energy self-consumption?<span aria-hidden=\"true\">+<\/span><\/summary>\n<div class=\"approved-reading faq-answer\">\n<p><strong>Yes, in some situations vertical photovoltaics can support self-consumption<\/strong>because electricity generation may be distributed differently throughout the day compared with a conventional rooftop system.<\/p>\n<p>For example, a vertical installation with east- and west-facing surfaces can make use of certain morning and afternoon hours when a building may have significant consumption.<\/p>\n<p>The actual benefit depends on orientation, exposure and the consumption profile. It is therefore incorrect to say that a vertical system always generates more energy or necessarily delivers greater savings.<\/p>\n<\/div>\n<\/details>\n<details id=\"faq-3\">\n<summary>3. Do vertical photovoltaic panels generate energy in the morning and evening too?<span aria-hidden=\"true\">+<\/span><\/summary>\n<div class=\"approved-reading faq-answer\">\n<p><strong>Yes. The orientation of vertical modules can enable them to capture a useful share of energy in the first and last hours of daylight<\/strong>particularly in certain east-west configurations.<\/p>\n<p>This profile can be useful for businesses, hospitality facilities and users that consume electricity in the morning and afternoon.<\/p>\n<p>However, generation depends on the season, orientation, shading and available solar radiation. Performance must always be assessed at the installation site.<\/p>\n<\/div>\n<\/details>\n<details id=\"faq-4\">\n<summary>4. What are bifacial photovoltaic panels and what benefits do they offer?<span aria-hidden=\"true\">+<\/span><\/summary>\n<div class=\"approved-reading faq-answer\">\n<p><strong>Bifacial photovoltaic panels are modules that can convert sunlight reaching both their surfaces into electricity.<\/strong><\/p>\n<p>Unlike conventional panels, which mainly use the front side, bifacial modules can also use direct or reflected radiation reaching the back.<\/p>\n<p>This technology is particularly interesting for vertical photovoltaics, where both sides can be exposed to light.<\/p>\n<p>The actual contribution of the rear side depends on installation conditions. SalvaTerra uses bifacial modules in configurations that specify them.<\/p>\n<\/div>\n<nav class=\"faq-related\" aria-label=\"Read more about answer 4\"><a href=\"https:\/\/etway.it\/en\/?page_id=11377#forme\">Prime\u2019s modules<\/a><\/nav>\n<\/details>\n<details id=\"faq-5\">\n<summary>5. Does SalvaTerra really generate usable renewable energy?<span aria-hidden=\"true\">+<\/span><\/summary>\n<div class=\"approved-reading faq-answer\">\n<p><strong>Yes. SalvaTerra incorporates real photovoltaic modules that convert sunlight into electricity.<\/strong><\/p>\n<p>The energy can be used in the building or area served through a properly designed and connected system. In specific configurations, it can also power dedicated loads or be stored in batteries.<\/p>\n<p>Installed power and annual generation vary according to the model, number of units, exposure and climate conditions.<\/p>\n<p>SalvaTerra is therefore more than a decorative element with a sustainability theme: it is a solar energy generation solution.<\/p>\n<\/div>\n<\/details>\n<details id=\"faq-6\">\n<summary>6. What do the microinverters and MPPT system in SalvaTerra modules do?<span aria-hidden=\"true\">+<\/span><\/summary>\n<div class=\"approved-reading faq-answer\">\n<p><strong>Microinverters convert the electricity generated by photovoltaic panels into alternating current that the system can use.<\/strong><\/p>\n<p>In configurations that use them, they enable distributed electrical management of the modules. The MPPT system, or <em>Maximum Power Point Tracking<\/em>seeks the operating conditions that make the best use of the available power.<\/p>\n<p>This feature can be useful when modules have different exposures or experience uneven shading.<\/p>\n<p>For larger installations, centralised inverters or other electrical architectures may also be considered: the choice depends on the project.<\/p>\n<\/div>\n<nav class=\"faq-related\" aria-label=\"Read more about answer 6\"><a href=\"https:\/\/etway.it\/en\/?page_id=11371#forme\">Light\u2019s features<\/a><\/nav>\n<\/details>\n<\/div>\n<\/section>\n<section class=\"faq-category\" id=\"faq-gruppo-2\" aria-labelledby=\"faq-heading-2\">\n<h2 id=\"faq-heading-2\">Materials, design and accessories<\/h2>\n<div class=\"approved-faq-list\">\n<details id=\"faq-7\">\n<summary>7. What is Corten steel and why is it used in SalvaTerra?<span aria-hidden=\"true\">+<\/span><\/summary>\n<div class=\"approved-reading faq-answer\">\n<p><strong>Corten steel is a special steel designed to develop, in suitable environmental conditions, a surface oxidation patina that slows subsequent corrosion.<\/strong><\/p>\n<p>Its most recognisable feature is its warm colour, with brown and reddish tones that change naturally over time. This makes it highly valued in contemporary architecture, street furniture and garden design.<\/p>\n<p>Alongside its appearance, Corten can offer high durability without the painting cycles required by many conventional steels.<\/p>\n<p>The protective patina develops properly mainly through alternating wetting and drying. During the initial phase, runoff can stain pale paving: an aspect to consider in the design.<\/p>\n<p>Within the SalvaTerra range, versions made from genuine Corten steel must be distinguished from any painted Corten-effect finishes.<\/p>\n<\/div>\n<\/details>\n<details id=\"faq-8\">\n<summary>8. Can I integrate a bicycle rack or e-bike charging?<span aria-hidden=\"true\">+<\/span><\/summary>\n<div class=\"approved-reading faq-answer\">\n<p><strong>Yes. SalvaTerra can be configured to integrate sustainable mobility services<\/strong>such as bicycle racks and charging points for electric bicycles.<\/p>\n<p>This is an interesting option for hotels, campsites, agritourism properties, businesses, cycle paths and public areas.<\/p>\n<p>In this way, a photovoltaic planter can contribute both to renewable energy generation and to providing useful services for customers, staff and visitors.<\/p>\n<p>Charging arrangements, available power and any storage systems must be defined during the design phase.<\/p>\n<\/div>\n<nav class=\"faq-related\" aria-label=\"Read more about answer 8\"><a href=\"https:\/\/etway.it\/en\/?page_id=11383#vantaggio-5\">Explore the integrations<\/a><\/nav>\n<\/details>\n<details id=\"faq-9\">\n<summary>9. Can seats or benches be integrated into the photovoltaic planter?<span aria-hidden=\"true\">+<\/span><\/summary>\n<div class=\"approved-reading faq-answer\">\n<p><strong>Yes, some configurations and customised solutions can include integrated seating<\/strong>turning the planter into a furnishing element for rest and social interaction.<\/p>\n<p>This solution is particularly interesting for terraces, gardens, outdoor dining areas, business entrances, hospitality facilities and public spaces.<\/p>\n<p>The result is a furnishing that combines greenery, energy generation and people\u2019s comfort.<\/p>\n<p>Seating availability depends on the model and project: it is not a standard accessory on every SalvaTerra version.<\/p>\n<\/div>\n<nav class=\"faq-related\" aria-label=\"Read more about answer 9\"><a href=\"https:\/\/etway.it\/en\/?page_id=11367#forme\">Deluxe with bench<\/a><\/nav>\n<\/details>\n<details id=\"faq-10\">\n<summary>10. Can I add an LED lighting system?<span aria-hidden=\"true\">+<\/span><\/summary>\n<div class=\"approved-reading faq-answer\">\n<p><strong>Yes. SalvaTerra can be prepared to integrate LED lighting systems<\/strong>to enhance outdoor spaces and make them more usable in the evening.<\/p>\n<p>Lighting can serve a decorative, wayfinding or practical purpose, depending on the setting.<\/p>\n<p>To operate when sunlight is unavailable, lighting points must be powered by the electricity grid or a suitably sized storage system.<\/p>\n<\/div>\n<\/details>\n<details id=\"faq-11\">\n<summary>11. Can I integrate cameras, sensors or monitoring systems?<span aria-hidden=\"true\">+<\/span><\/summary>\n<div class=\"approved-reading faq-answer\">\n<p><strong>Yes, in configurations designed for these uses, SalvaTerra can accommodate technological devices<\/strong> such as cameras, environmental sensors and monitoring systems.<\/p>\n<p>These integrations can be useful for businesses, car parks, public areas and hospitality facilities looking to combine several services in one furnishing element.<\/p>\n<p>Devices, power supply and connectivity are chosen according to the project\u2019s needs. For cameras, the applicable privacy and video surveillance rules must also be followed.<\/p>\n<\/div>\n<nav class=\"faq-related\" aria-label=\"Read more about answer 11\"><a href=\"https:\/\/etway.it\/en\/?page_id=11381\">Survival for standalone loads<\/a><\/nav>\n<\/details>\n<details id=\"faq-12\">\n<summary>12. Can I use SalvaTerra for plants, flowers or small shrubs?<span aria-hidden=\"true\">+<\/span><\/summary>\n<div class=\"approved-reading faq-answer\">\n<p><strong>Yes. SalvaTerra was created specifically to combine greenery with photovoltaic energy generation.<\/strong><\/p>\n<p>The planter can accommodate plant species suited to its size and the local conditions, creating ornamental arrangements for gardens, terraces, entrances and public spaces.<\/p>\n<p>Plant selection must consider root space, irrigation, drainage, substrate weight and sun exposure.<\/p>\n<p>It is also important to prevent growing vegetation from excessively shading the photovoltaic modules.<\/p>\n<\/div>\n<\/details>\n<details id=\"faq-13\">\n<summary>13. Are glass-glass panels different from normal solar panels?<span aria-hidden=\"true\">+<\/span><\/summary>\n<div class=\"approved-reading faq-answer\">\n<p><strong>Yes. In glass-glass photovoltaic panels, the cells are enclosed between two sheets of glass<\/strong>rather than a front glass sheet and a different rear material.<\/p>\n<p>This construction can offer benefits in protection and durability, depending on the specifications of the module used.<\/p>\n<p>The solution is particularly interesting for certain bifacial and architecturally integrated photovoltaic applications, where appearance and surface exposure also matter.<\/p>\n<p>The type of panel fitted to SalvaTerra depends on the chosen configuration.<\/p>\n<\/div>\n<\/details>\n<\/div>\n<\/section>\n<section class=\"faq-category\" id=\"faq-gruppo-3\" aria-labelledby=\"faq-heading-3\">\n<h2 id=\"faq-heading-3\">Installation, projects and applications<\/h2>\n<div class=\"approved-faq-list\">\n<details id=\"faq-14\">\n<summary>14. Can SalvaTerra be supplied with an assembly kit?<span aria-hidden=\"true\">+<\/span><\/summary>\n<div class=\"approved-reading faq-answer\">\n<p><strong>Yes. Depending on the configuration and supply arrangement, SalvaTerra can come with the components and preparations required for assembly.<\/strong><\/p>\n<p>The aim is to simplify assembly and make installation as orderly and predictable as possible.<\/p>\n<p>However, structural assembly must be distinguished from electrical connection: the latter requires checks, protection and qualified personnel in accordance with applicable regulations.<\/p>\n<p>The included components are defined in the technical quotation.<\/p>\n<\/div>\n<\/details>\n<details id=\"faq-15\">\n<summary>15. Can I use SalvaTerra without work on the building\u2019s roof?<span aria-hidden=\"true\">+<\/span><\/summary>\n<div class=\"approved-reading faq-answer\">\n<p><strong>Yes. This is one of SalvaTerra\u2019s main advantages: the panels are integrated into the planter and do not need to be installed on the roof.<\/strong><\/p>\n<p>The solution is useful where the roof is hard to access, shaded, architecturally sensitive or already occupied by other systems.<\/p>\n<p>However, choosing to install photovoltaics at ground level, in a garden or on a terrace does not remove the need for feasibility, safety and permit checks for the selected location.<\/p>\n<\/div>\n<nav class=\"faq-related\" aria-label=\"Read more about answer 15\"><a href=\"https:\/\/etway.it\/en\/?page_id=11393\">The iWIM project<\/a><\/nav>\n<\/details>\n<details id=\"faq-16\">\n<summary>16.
