Higher capacity supply — larger homes, GCBs, or homes with EV chargers. Supports larger systems
That’s okay — Sunollo will check this during your free site assessment
Most common in terrace homes — may require longer AC cable routing from inverter
Often near car porch or front door — shorter AC runs, simpler cable routing
Sometimes found on upper floors or in utility rooms — routing assessed during site visit
No worries — Sunollo locates and assesses your DB during the free site assessment
Exterior side wall — close to roof, good ventilation, easy service access
Near the car porch or driveway — sheltered, convenient for EV charger pairing
Rear exterior wall — hidden from street view, weather-protected in many layouts

Based on your selections, the guide below highlights what applies to your home. Scroll down to explore each section.
A clear, visual guide to roofs, mounting systems, inverter placement, cable routing, and finishing standards — designed to help you understand what to expect before your site assessment.
Every home is unique. Final design always depends on your specific roof, structure, and electrical layout — confirmed during Sunollo’s detailed site assessment.
Many homeowners want to visualise how solar will actually look and work on their home — before committing to anything. This guide explains the decisions, standards, and care that go into every Sunollo installation.
Every home is different. But the principles we follow are consistent: safety, neatness, durability, and respect for your home’s architecture. Understanding these principles helps you feel confident about the process ahead.
Your roof type determines the mounting method, panel layout, and cable routing approach. Here are the most common roof types we work with on Singapore landed homes.
The most common roof type on Singapore landed homes. Requires rail-based mounting with tile hooks that slip under existing tiles without damage.
Found on some modern landed homes and extensions. Allows direct clamp mounting without roof penetration, making installation faster and waterproof by design.
Common on terrace houses and some semi-detached homes. Uses weighted or ballasted mounting frames that can be angled for optimal sun exposure.
Premium roofing with raised seams. Panels attach with non-penetrating seam clamps, preserving the roof’s integrity and clean architectural lines.
How panels are physically attached to your roof. The method depends on your roof type, structural conditions, and aesthetic preferences.
Tile hooks slide under existing tiles, supporting aluminium rails where panels are secured. No tiles are removed or broken. Waterproofing is maintained throughout.
Clamps grip directly onto metal roof seams or ribs without drilling. Fast to install, inherently waterproof, and ideal for standing seam or corrugated metal roofs.
The panels themselves vary in appearance, efficiency, and suitability. Your choice affects both performance and how the system looks on your roof.
Premium appearance with black cells, frame, and backsheet. High efficiency and minimal visual clutter on your roof. Sunollo’s most popular choice for design-conscious homeowners.
High-efficiency cells with a silver aluminium frame. Slightly lower cost than all-black options while maintaining excellent performance and durability.
The inverter converts DC electricity from your panels into AC power your home can use. Different inverter types suit different roof layouts and future expansion plans.
A single unit that converts power from all panels. Cost-effective and well-suited to roofs with consistent sun exposure and minimal shading.
Individual optimisers on each panel maximise output even when some panels are shaded. Ideal for complex roof layouts or partially shaded conditions.
Your main distribution board (DB) is where the solar system connects to your home’s electrical grid. Its location directly affects how AC cables are routed from the inverter.
Where the inverter sits on your home depends on proximity to the roof, distance to your distribution board, ventilation, weather protection, and aesthetics. Here are the most common placements.
DC cables carry electricity from your roof panels down to the inverter. The route is planned carefully to minimise visual impact, protect cables from weather, and ensure safe, accessible connections.
AC cables run from the inverter to your main distribution board. Some routes are short and simple. Others may require visible conduit along walls — always finished neatly and aligned with Sunollo’s visual standards.
Where cables must run along visible walls, Sunollo uses rectangular white conduit with neat corners, disciplined alignment, and clean penetrations. This is where obsessive attention to detail becomes visible.
Every installation reflects our belief that solar should be as beautiful as it is functional. These are the principles that guide every decision our team makes on your roof and around your home.
Every panel is aligned precisely to your roof geometry. No uneven gaps, no misaligned rows.
All cables are secured, clipped, routed through conduit where visible, and labelled at junction points.
We plan routes to minimise visible runs. Where conduit is needed, it follows architectural lines.
Your home’s design language is considered at every stage. Equipment placement respects façade lines and proportions.
Components are installed with future maintenance in mind. Nothing is buried or inaccessible.
Roof penetrations are sealed, cables are UV-protected, and all exterior components are rated for tropical conditions.

Solar installations in Singapore follow specific technical standards. Here’s what they mean in plain language — and how Sunollo applies them with discipline.
Singapore’s primary standard for solar installations. It covers system design, wiring, protection, and connection to the electricity grid. Sunollo designs and installs every system in full compliance with SS 638, ensuring your system is safe, efficient, and approved for grid connection.
The Energy Market Authority oversees how solar systems connect to Singapore’s electricity grid. Sunollo handles all EMA documentation and ensures your system qualifies for net metering — meaning excess energy you produce is credited back to your electricity account.
Before installation, Sunollo assesses whether your roof can safely support the additional weight of solar panels and mounting hardware. This includes reviewing structural drawings where available, and conducting on-site structural checks to ensure long-term safety.
Practical answers to the questions homeowners ask most about solar installation, cable visibility, inverter placement, and finishing standards.
It depends on where your inverter and distribution board are located. In many cases, most cabling runs through the roof space or along hidden areas. Where cables must cross visible walls, Sunollo uses neat rectangular conduit that follows architectural lines — always white, always aligned.
Typically on an exterior wall near the roof — such as a side wall, car porch area, or backyard. The location is chosen to minimise cable runs, ensure good ventilation, and keep the inverter accessible for future servicing.
Many Singapore homes have the DB under the stairs or in a utility area. When the DB is inside, the AC cable route is usually longer and may require conduit along an exterior wall to reach an entry point. Sunollo plans this route carefully to minimise visual impact.
Yes. Tiled roofs use tile hooks and rails. Metal roofs use clamps. Flat roofs use weighted frames. Each method is specifically designed for that roof type to ensure structural safety, waterproofing, and long-term durability.
In most cases, DC cables on the roof and inverter connections can be concealed. Some AC cable runs may require visible conduit depending on your home’s layout. Sunollo always plans to minimise visibility, and uses premium white rectangular conduit where exposure is unavoidable.
The exact panel layout, inverter placement, cable routing, conduit requirements, structural adequacy, and shading analysis are all confirmed during Sunollo’s site assessment. This guide explains the general principles — your specific design is tailored to your home.
