Yes. solar shingle are designed to be the roof covering itself and are installed using conventional roofing methods. The curved and flat profiles match standard roof dimensions, so structural changes are usually not required. How efficient are solar tiles? GreenMore solar tiles use two cell technologies. Our back-contact crystalline tiles reach up to 24.1% module efficiency, while our thin-film solar tiles deliver around 20% efficiency with strong performance in low light, high temperatures and partial shading. Actual output depends on roof orientation, shading, local irradiance and system configuration. What is the difference between solar tiles and conventional solar panels? Conventional panels are mounted on rails above an existing roof, whereas solar tiles are the roof covering itself. Solar tiles remove the need for separate racking, give a cleaner integrated appearance and are often preferred for new builds and roof renovations. Rack-mounted panels generally have a lower upfront cost and are easier to fit on an existing roof. How much maintenance do solar tiles require? Very little. The double-glass surface is durable and weatherproof, and normal rainfall helps wash away dust. In dry or dusty locations, an occasional visual inspection and gentle cleaning will keep output high. The waterproof overlapping design and secure fastening reduce the need for ongoing roof maintenance. What warranty is provided? The solar tiles carry a 25-year power warranty. When the system includes storage inverters or lithium batteries, those components carry a separate 3-year warranty. Does GreenMore support distributors and OEM projects? Yes. GreenMore supplies system design, technical documentation and remote commissioning support, and offers OEM customization for tile dimensions, colours and electrical specifications to meet local building codes.

Frequently Asked Questions What is a home solar system? A home solar system generates electricity from rooftop PV panels, stores surplus energy in a household battery and manages usage through a smart inverter. It lets a home use its own clean power, with the grid as backup when needed. How much can I save on electricity bills? Savings depend on roof size, local sunlight, electricity tariffs and how much power is used during the day. With self-consumption and battery storage, a well-sized system can cover a large share of household consumption and reduce bills substantially over its life. Will my home still have power during an outage? Yes. A system with battery backup switches to off-grid mode automatically when the mains fail, keeping essential loads such as lighting, the refrigerator, router and security cameras running until power returns. Can solar be installed without damaging my roof? Yes. Systems can use conventional, lightweight or bonded mounting suited to the roof type, and installers protect the existing waterproofing and finish. Tiled, steel and concrete roofs can all be fitted with appropriate fixing methods. Can I add a battery or expand later? Yes. Modular inverters and batteries allow storage to be added or capacity increased without replacing the whole system, provided the initial equipment is chosen to support expansion. What warranty and support are provided? PV modules carry a 25-year power warranty, while the inverter and lithium battery carry a 3-year warranty. GreenMore provides installation guidance, app-based monitoring, spare parts and after-sales support for homeowners and installation partners. Want a solar system sized for your home?

A flexible BIPV roof system uses lightweight, bendable solar modules that are bonded or laid directly onto the roof surface. At roughly 2.5–6 kg/m², the modules are far lighter than conventional glass panels and follow curved, irregular or load-limited roofs with few or no penetrations. This makes them well suited to retrofits and architecturally complex buildings — provided heat dissipation, bonding durability, fire and electrical safety are engineered properly. Flexible BIPV is not a universal upgrade over rigid panels; it is the right choice where low weight, shape adaptability and a non-penetrating installation matter most. At a Glance Lightweight Typically 2.5–6 kg/m², for roofs that cannot carry glass panels. Bendable Follows curved, arched and irregular roof surfaces. Non-penetrating Bonded or laid in place, reducing roof damage and leak risk. Cell options Flexible crystalline, thin-film and emerging perovskite. Advantages and Engineering Considerations Aspect Advantage What to verify Weight & load Much lighter than glass modules; suits load-limited roofs. Confirm roof capacity, wind load and snow load. Shape Bends to curves, arcs and irregular surfaces. Bend radius and bonding flatness affect output and life. Installation Bonded or laid with few holes, less racking. Validate adhesive ageing, de-bonding and wind lift. Building integration Translucent, coloured and curtain-wall options. Transparency and colour can reduce efficiency. Performance Flexible crystalline can exceed 23%; thin-film performs well in low light. Some flexible modules still trail premium rigid panels. Durability No glass, good impact resistance, easy handling. Check weathering, yellowing, delamination and moisture ingress via certifications and warranty. Cell Technologies Flexible crystalline is closest to a conventional generation scenario, with flexible crystalline modules now reaching 23% or higher. Thin-film offers advantages in translucency, colour options and low-light or high-temperature performance. Perovskite shows strong potential for ultra-light, curved and indoor low-light applications, though long-term outdoor stability at scale is still being validated. GreenMore selects the technology based on roof geometry, irradiance and project lifetime requirements. Suitable Buildings Load-limited roofs: older factories, colour-coated steel (corrugated) roofs, light-steel and grid structures, rural buildings, coal sheds and carports. Curved or irregular architecture: arched roofs, spherical or wave-shaped venues, artistic buildings, irregular facades and historic-building renovations. Waterproofing-sensitive roofs: commercial, industrial or residential roofs that should not be drilled or have their existing waterproofing disturbed. Daylighting or aesthetic builds: skylights, glazed roofs, curtain walls, atriums, cultural venues and villa facades. Coastal, humid and salt-spray locations: use well-encapsulated modules and verify salt-mist, damp-heat, fire and electrical certifications. Typical Applications C&I rooftop retrofits Existing roofs that cannot be reinforced, shut down or penetrated. BIPV integration Curtain walls, skylights, eaves, sunshades and balcony facades. Rural pitched roofs Laid onto tiled or sloped roofs with minimal structure change. Mobile & specialised RVs, boats, trucks, vehicles, agricultural sheds, floating systems and portable power. What GreenMore Verifies Before Installation Remaining roof load, wind-lift risk and waterproofing detail IEC / UL certification, fire rating, and salt-mist / damp-heat testing Whether the installation is adhesive, mechanically fixed or hybrid Power warranty, degradation curve and alignment with the service-life target Thermal design to avoid hot spots and output loss from full-coverage laying Future inspection, module replacement and end-of-life recycling path Frequently Asked Questions What is flexible BIPV? Flexible BIPV uses lightweight, bendable solar modules that are bonded or laid directly onto a building surface instead of framed glass panels on rails. The modules become part of the roof or facade, suiting curved and load-limited structures. When should I choose flexible modules instead of rigid panels? Choose flexible modules when the roof cannot support the weight of glass panels, follows a curved or irregular shape, or cannot be penetrated without risking waterproofing. For roofs with ample load capacity and a long service-life requirement, rigid panels often remain the more cost-effective choice. Will bonding modules damage the roof or cause leaks? A non-penetrating bonded installation reduces roof damage and leak risk compared with drilling, but the adhesive must be specified for the roof material and local climate. GreenMore reviews the existing waterproofing, bonding method and wind-lift loads before installation and can combine modules with a compatible waterproof membrane. How efficient are flexible solar modules? Flexible crystalline modules now reach 23% or higher, close to conventional panels, while thin-film modules perform well in low light and high temperatures and offer translucent or coloured options. Output also depends on roof orientation, curvature, shading, ventilation and system design. How durable are they, and what warranty applies? Flexible modules have no glass to break and resist impact well. Long-term performance depends on the encapsulation resisting yellowing, delamination and moisture ingress, so certified products with a documented power warranty and degradation curve should be used. Exact warranty terms follow the module datasheet; where a system includes storage inverters or lithium batteries, those components carry a 3-year warranty. Are they suitable for coastal or high-humidity locations? Yes, when using modules with durable encapsulation and verified salt-mist, damp-heat, fire and electrical certifications. GreenMore checks these requirements for each coastal or high-humidity project rather than assuming a standard module is suitable. Have a load-limited or curved roof? Send us the roof dimensions, structure type and location, and GreenMore will assess whether a flexible BIPV system is the right fit.

Remote and weak-grid sites Islands, mines and rural stations that replace costly diesel generation and reduce operating expense. Tourism and municipal landscapes Flexible PV and metal BIPV roofs that combine power generation with architectural appearance. Six Core System Modules Renewable Generation Distributed rooftop or ground-mount PV, with wind where the resource suits, supplies the primary clean energy and offsets grid consumption during daylight hours. Battery Energy Storage Lithium battery systems with integrated fire protection, thermal control and BMS store surplus energy, shave peaks, smooth load and provide emergency backup — the module that keeps the microgrid stable and profitable. Intelligent Power Distribution High- and low-voltage distribution cabinets, grid-connection cabinets, breakers and lightning protection safely transfer and allocate power between generation, storage, the grid and loads. Energy Management System (EMS) The brain of the microgrid monitors generation, consumption, storage and time-of-use prices around the clock, then schedules charging in low-price periods, discharging in peaks and seamless grid-to-island switching to maximise returns. Load Monitoring and Energy Control Production equipment, lighting and HVAC loads are metered, analysed and controlled in real time, pinpointing waste so energy can be managed precisely and overall cost reduced. Safety, Security and O&M Monitoring Fire warning, temperature and humidity sensing, smoke detection, video surveillance, remote O&M and fault alarms keep the system safe, compliant and dependable over its operating life. System Connection Diagram Core Functions and Benefits Flexible dual-mode operation: seamless on-grid and off-grid switching — arbitrage while the grid is healthy, independent supply when it fails. Clear cost savings: self-consumption offsets peak tariffs, peak-valley arbitrage and reduced demand charges lower the electricity bill. Reliable power supply: addresses rationing, outages and voltage fluctuation and keeps critical loads running. Green and compliant: raises the share of clean power and supports energy-control, carbon-neutral and green-factory or park certification. Smart, low-labour O&M: cloud monitoring, automatic dispatch and fault warnings cut manual operating cost. Works with any building: pairs with conventional PV, flexible BIPV or metal solar roofs, on new and existing structures.

Frequently Asked Questions What is a smart microgrid? A smart microgrid is a local energy system that combines distributed generation, battery storage, intelligent distribution and an energy management system. It can operate connected to the grid or independently, balancing local supply and demand automatically. Can a microgrid switch between grid-tied and off-grid operation? Yes. When the grid is available, the system runs grid-tied to self-consume and capture peak-valley arbitrage. If the grid fails, it transfers to island mode and keeps critical loads powered from PV and batteries, switching back seamlessly on restoration. How does a microgrid reduce electricity costs? It raises self-consumption of on-site solar so less expensive peak-hour grid power is imported, stores low-price energy for high-price periods, lowers demand charges and reduces waste through real-time load monitoring. Is a microgrid suitable for a weak-grid or no-grid site? Yes — it is one of the strongest use cases. PV and battery storage replace or support unreliable grid supply and diesel generators, providing stable power for islands, mines, rural stations and remote communities while lowering fuel and maintenance costs. Can the system be integrated with BIPV roofs? Yes. The microgrid works with conventional PV as well as flexible BIPV and standing-seam metal BIPV roofs, so new or existing buildings can combine integrated solar roofing with storage and smart energy management. What warranty and support are provided? The system is designed for a 25-plus-year service life. Lithium batteries, power-conversion and energy-management components carry a 3-year warranty, backed by design support, remote monitoring, spare parts and commissioning assistance for EPC partners and owners.

GreenMore metal roof BIPV replaces the conventional roof itself with photovoltaic metal panels. The modules are laminated onto a metal substrate and joined by a 360° standing-seam lock, so the roof is simultaneously the weather envelope and the power generator — no exposed screws, strong wind-uplift resistance and a clean unified facade. It is the preferred roofing system for new large-span steel-structure factories, warehouses and public buildings that need reliable waterproofing and on-site solar generation in one build. Two Concepts: BIPV and BAPV BIPV integrated PV metal roof BAPV attached to an existing roof The PV module is the metal roof panel, replacing aluminium-magnesium-manganese or colour-coated steel roofing. Standard panels are added to an existing standing-seam roof with clamps and rails; the original roof and its waterproofing stay in place. Best for new builds; the roof and PV share one service life. Fast, non-penetrating retrofit for sound existing metal roofs. Why Choose a Metal BIPV Roof Structural Waterproofing and Wind Resistance Panels are joined with a 360° standing-seam lock based on the equalised-pressure principle, with no exposed fasteners between panels. The composite PV-and-metal roof is itself the waterproof component, achieving a reliable secondary waterproofing grade and resisting strong wind and typhoons — well suited to large-span steel structures. For retrofit projects, clamp-mounted BAPV grips the seam without drilling and preserves the existing roof's waterproofing. Moderate Weight, Better Cooling A finished metal BIPV roof weighs about 8–12 kg/m², far less than a concrete roof. A ventilated cavity beneath the modules dissipates heat better than a directly bonded flexible system, reducing high-temperature power loss and keeping output close to conventional rigid crystalline panels. Strong Fire and Hail Performance The substrate is typically colour-coated steel or aluminium-magnesium-manganese with rock-wool or polyurethane insulation, supporting a high fire rating for factory and warehouse requirements. The glass module surface also resists hail better than flexible membrane materials. Matched Service Life and Easy Maintenance The metal envelope and PV modules are designed to age together, so the roof does not have to be separately replaced midway. With dedicated maintenance walkways, the walkable surface is straightforward to inspect and clean, improving whole-life economics. Integrated Building Performance Insulation, sound absorption and thermal performance can be built into the assembly. Black modules with metal trim give a uniform architectural finish; the system works best on straight roof slopes and can also follow gentle curves. Limitations to Consider Higher cost: more expensive than standard colour-coated steel plus BAPV, so it pays off mainly on new builds, not on retrofitting old steel roofs. Fabrication and transport: panels are custom long boards with lifting and hauling constraints, and on-site seaming demands skilled workmanship — a poorly closed seam will leak. Thermal movement: metal expands and contracts significantly, so sliding T-brackets are required to prevent bulging and deformation. Heavier than flexible BIPV: not suitable for older buildings with insufficient load capacity. Where It Fits Best Recommended New large-span steel factories and workshops Logistics centres and cold-storage warehouses Exhibition centres, rail stations, stadiums, office parks New prefabricated and large commercial buildings Coastal typhoon-prone regions Not recommended Retrofitting old colour-coated steel roofs — use clamp BAPV or flexible PV instead Old buildings with seriously limited load capacity Tight-curvature irregular surfaces — flexible BIPV is preferable Temporary or low-budget buildings Installation Process for New Metal BIPV Roofs Survey and structural check: verify steel purlins, bracket spacing, wind and snow loads; finalise layout, drainage, ridge and gutter details, and electrical routing. Structural base: install purlins and liner, insulation and breathable membrane, then fixed and sliding T-brackets that absorb thermal movement. Panel laying: lift the integrated PV metal panels into place, overlap them and form the 360° standing-seam lock with an electric seamer; fit ridge, gutter and gable trims, end closures and flashings. Electrical work: connect pre-fitted junction boxes, run DC cables in metal conduit through the roof cavity, wire the strings and bond the earthing. Waterproofing re-check: inspect seam quality and gutter drainage, seal foam closures and apply weatherproof sealant at every termination and penetration. Inverter and combiner boxes: install combiner boxes and inverters, connect DC to the inverter and the AC side to the distribution room. Testing and grid acceptance: insulation resistance, EL and array performance tests, lightning-protection re-test, grid commissioning and handover documentation. BAPV retrofit on an existing standing-seam roof is simpler — survey and structural check, clamp aluminium fixtures to the seam, fit rails, secure modules with clamps, route and earth the cabling, then commission. The whole process is non-penetrating and faster. Key Risk Controls Seam quality: inadequate on-site seaming is the main leak cause and should be supervised throughout. Thermal movement: sliding brackets are mandatory; panels must not be fully fixed. Lightning and earthing: the metal roof acts as a natural down-conductor, so modules, clamps and rails must be reliably cross-bonded. Drainage: module layout must not block gutters, to avoid standing water and ice build-up. Corrosion: coastal projects use aluminium-magnesium-manganese substrates and high-corrosion-resistant fittings. Frequently Asked Questions What is metal roof BIPV? Metal roof BIPV is a roof system in which photovoltaic modules are laminated onto metal panels that replace the conventional roof covering. The panels are joined with a 360° standing-seam lock, so the roof both waterproofs the building and generates electricity. What is the difference between BIPV and BAPV on a metal roof? BIPV replaces the roof with power-generating metal panels and suits new builds. BAPV adds standard panels to an existing standing-seam roof using clamps and rails without drilling, which is faster and more economical for retrofits where the existing roof is in good condition. How waterproof and wind-resistant is a standing-seam BIPV roof? The 360° seam has no exposed screws and uses an equalised-pressure design, making the roof itself the waterproof component with strong wind-uplift and typhoon performance. Waterproofing still depends on correct seaming and properly finished ridge, gutter and penetration details. Is a metal BIPV roof better than flexible BIPV? They serve different buildings. Metal BIPV offers stronger waterproofing, better ventilation and cooling, higher fire and hail resistance, but it is heavier and more expensive. Flexible BIPV is ultra-light and bendable for old or curved roofs but is more vulnerable to hail and runs hotter. Metal BIPV is the usual choice for new steel-structure buildings. Can the system be installed on an existing metal roof? If the existing roof and structure are sound, non-penetrating BAPV using seam clamps and rails is usually the better option. Replacing the whole roof with integrated BIPV panels is generally not cost-effective unless the old roof already needs to be removed. What warranty and support are provided? The PV modules carry a 25-year power warranty, and the metal roof and PV are designed for matched service life with appropriate maintenance. Where a system includes storage inverters, PCS or lithium batteries, those components carry a separate 3-year warranty. GreenMore provides structural detailing, installation guidance and commissioning support. Planning a new steel-structure roof?
