Triple-Arch Hantile

L Luke Product Manager, GreenMore · BIPV solar tiles, facades & storage Israel has some of the best rooftop solar conditions in the region — more than 3,000 hours of sunshine a year and peak sun hours around 5.3 to 6.0 depending on the location. Homeowners here increasingly want that resource used without putting an industrial-looking array on a house they have spent money on designing. This short project note covers a residential roof we completed with our curved photovoltaic tiles and a home battery, including what was fitted and how the system behaves in the local climate. Project Background Israel’s national policy aims for 30% of electricity to come from renewable sources by 2030, most of it solar, and households are encouraged to generate on their own roofs. The homeowner had two practical concerns that come up often in this market: conventional panels sit visibly above the roofline and change how the house looks, and in a dusty, hot climate panels can lose output to soiling and high operating temperatures. The goal was therefore a roof that generated its own power, stored some for evening use and still looked like a normal finished roof. Photos of the Israeli Tri-Curve Solar Tile Project What We Installed Triple-arch photovoltaic tiles The roof uses our triple-arch solar tiles, which follow the curve of traditional clay tiling rather than sitting on a rack. They are built from laminated toughened glass, rated for 5400 Pa static load and Class A fire performance, and operate across −40 °C to +85 °C, which suits both the hot inland summers and coastal humidity. A few design points matter for this climate: The curved profile sheds rain and, because dust does not settle as flatly on a smooth curved surface, normal rainfall helps keep the glass cleaner between washes. The tiles are laid with an air gap behind them, so heat can escape rather than being trapped against the roof, helping the cells run closer to their rated temperature. Colors are matched to the building so the finished roof reads as tiling rather than equipment. Home battery and hybrid inverter Household demand in Israel tends to peak in the late afternoon and evening, after midday generation has passed its peak. We therefore paired the tiles with a stackable home battery from our energy storage range and a hybrid inverter with MPPT tracking. The combination covers three functions: daytime self-consumption, storing midday surplus for the evening, and backup for selected loads during an outage on an island-capable setup. Capacity is chosen per household; a 10–15 kWh battery is a common fit for a home of this size, and stackable units can be extended later if the family’s use grows. System Layout and Expected Output The pitched roof offered roughly 140 m² of usable area. Fully tiled at the curved product’s density of around 103 W/m², that corresponds to about 14 kW and on the order of 420 tiles; in practice the exact count is adjusted around hips, edges and any areas kept clear. On a clear day at local peak sun hours, a system of this size would typically produce in the region of 60 kWh — well above a single household’s daily use, leaving surplus for charging the battery or exporting. We present these as indicative figures from the local solar resource rather than guaranteed meter readings; the real number moves with shading, orientation, soiling and the season. You can see the full tile family in our solar tile category and read more in what is a triple-arch hantile. What the Homeowner Told Us The feedback that matters most to us is the simple kind: the roof looks like a normal finished roof from the street, the house uses more of its own solar in the evening thanks to the battery, and the owner no longer treats a short grid interruption as a problem for the lights, refrigerator and internet. We do not attribute invented revenue or percentage figures to customers; the value is easier self-consumption, some backup and lower exposure to tariff rises. About GreenMore GreenMore is a photovoltaic tile factory. Our solar tiles, PV bricks and curtain walls are made in our own production facility, and we configure the matching inverter and battery around them so a homeowner or project partner sources a compatible system from one team. We are a focused, growing manufacturer rather than a mass producer, which lets us tailor colors and profiles and give each project direct support. On warranty, the photovoltaic tiles carry a 25-year power output warranty, while the inverter, battery and other non-tile components carry a 3-year warranty; the two are specified separately. Frequently Asked Questions Do solar roof tiles suit the Israeli climate? Yes. High irradiance suits generation, the laminated glass handles heat and UV, and the curved surface and rear air gap help with dust and temperature. Occasional washing in the dry season is still advisable. Is a battery necessary with the tiles? No. The tiles work grid-tied on their own. A battery mainly helps use midday generation in the evening and provides backup during outages, so it depends on the household’s routine and whether export terms are attractive. Can the system keep running during a power cut? With an island-capable hybrid inverter and battery, selected critical loads can keep running and the system isolates from the grid for safety. It backs up the circuits you choose rather than necessarily the whole house. Do you supply the tiles and storage together? Yes. As the tile manufacturer we supply the roof and configure a compatible inverter and battery for the local grid, so the parts are matched and supported through one contact.

L Luke Product Manager, GreenMore · BIPV solar tiles & roof systems As photovoltaic products move from industrial arrays onto everyday homes, buyers increasingly ask for solar that actually suits the building rather than sitting awkwardly on top of it. The triple-arch hantile is our answer to that. It is a curved solar roof tile shaped like a traditional clay tile, so the roof keeps its familiar look while it generates electricity. Here is a clear look at what it is, how it is built, where it works and how it pairs with energy storage. What Is a Triple-Arch Hantile? A hantile is a building-integrated photovoltaic (BIPV) roof tile. The word combines the Chinese character han with tile, and the product is designed to imitate the appearance of a traditional clay or cement roof tile. The “triple-arch” version uses a three-stage curved surface — a main arch with smaller side curves — that follows the silhouette of classic barrel and pantile roofs. The shape is not only decorative: the overlaps guide rainwater off the roof and help the tiles sit neatly together in rows. Technically, each tile is a laminated photovoltaic module. Solar cells are sealed between layers of toughened, high-transmittance glass and finished with edge protection and sealing strips, so the finished unit works as a weatherproof building material and a power generator in one. It replaces conventional tiles directly instead of being mounted above them. The full range is on our solar tiles category page. Real-life view of GreenMore residential wave-shaped photovoltaic tile pitched roof installation How It Is Built A few construction details matter more than impressive-looking percentages. These are the features the product is actually engineered around: Curved laminated glass The tile uses laminated, double-toughened curved glass with high light transmittance (above 91.5% on the glass itself). The laminate holds the glass together if it is ever broken, which is the same safety principle used in car windscreens, and the surface carries a nano self-cleaning coating so rain washes away dust. Overlapping, rail-light fitting Tiles overlap from left to right and bottom to top, with an up-and-down overlap of roughly 85 mm, so the joints shed water without exposed fixings through the waterproof layer. EPDM sealing strips and edge trims close the joints. The modular overlaps also absorb small construction tolerances, which makes laying them close to ordinary roofing work. Ventilation behind the tiles An air gap behind the tiles lets hot air rise and escape, cooling the cells naturally. Because photovoltaic output drops as the modules heat up, this rear ventilation helps steady production on sunny days. We treat it as good roof design rather than quoting a fixed extra percentage, since the gain varies with the roof and climate. Wind, load and fire performance The installed system is rated for a 5,400 Pa front static load, Class A fire performance and working temperatures from −40 °C to +85 °C. Our double-glass hantile roof system has been tested against wind speeds up to 177 km/h (level 15 typhoon). You can read more about the structural side in our pieces on how the tiles handle 5,400 Pa and fire ratings for solar roof tiles. Power and Cell Options The curved shape is available with two cell technologies, so buyers can balance appearance, efficiency and budget: CIGS thin film — a uniform, subtly colored surface with good response to diffused and morning/evening light. The classic 34 W three-arch tile delivers about 103 W per square metre; the HW32L model is rated at 32 W per tile. We have produced thin-film curved tiles since 2019. Back-contact crystalline (2025) — for maximum output from a limited area. The new BC curved tiles range from 37 W to 50 W per tile, with module efficiency up to 24.1%, while keeping the same traditional profile. Each tile measures roughly 720 × 500 mm and weighs about 6.5 kg, close to a conventional roof tile in handling. Exact electrical figures differ slightly between models, so the current datasheet is the reference for a specific order. Where It Is Used Villas and high-end homes where owners want solar without giving up a classic roofline. Heritage-style and cultural buildings, resorts and courtyards where flat panels would look out of place. Renovation and urban-renewal projects that re-roof in the original style while adding generation. Low-carbon communities combining distributed solar roofs with shared or home storage. Because the tiles form the finished weather surface rather than sitting above it, they are easiest to include when a roof is being built or re-covered. Our wider work in this area is collected under the BIPV systems section, and the fitting process is explained in our guide to installing solar tiles on a roof. Pairing the Tile with Energy Storage A solar tile roof generates while the sun is up, but households often use most of their electricity in the evening. A battery closes that gap, which is why many homes now plan the two together. Adding storage lets you: Use more of your own solar — store midday surplus and draw it down at night instead of buying it back. Shift load away from peak prices — charge in cheap periods and discharge when tariffs are high. Keep essentials running in an outage, where the inverter and battery are set up for backup. Monitor everything together — generation, battery state of charge and household use in one portal or app. Wall-mounted batteries suit homes short on space, while stacked batteries let capacity grow in modules. How the pieces work together is covered in our article on solar roof tiles with energy storage, and the options are listed under our home energy storage batteries. One point to keep clear: the photovoltaic tiles carry a 25-year linear power warranty, whereas the battery, inverter and other non-tile parts carry a 3-year warranty. They are specified separately. How to Choose the Right System When planning a triple-arch roof, with or without a battery, it helps to have a few facts ready: Roof area, orientation and pitch — these set how many tiles fit and how much they produce; south-facing planes usually lead. Average daily electricity use — used to size both the roof and any battery. Inverter and grid rules — whether you need a hybrid inverter for storage and what the local utility allows. Color and finish — standard colors are the most economical; custom colors can be matched to the building. Compatibility and support — confirm the tiles, inverter and battery are designed to work as one system and who supports them after delivery. GreenMore is a photovoltaic tile factory, and the triple-arch hantile is the product we built the company around.
