1. Roof Structural Assessment
We look at your roof's structure — what kind of trusses, whether they were designed with margin for additional load, whether any reinforcement is required before panels go on. This is the non-negotiable first step.
Most solar vendors are salespeople with installers. We're a BCA General Builder who also does solar — which means we assess whether your roof can actually carry the panels before we quote. Often it needs reinforcement first. Pure solar vendors miss this.
A typical solar panel system adds 15 to 25 kilograms per square metre of sustained load to your roof. Plus wind uplift. Plus the mounting structure. Plus any maintenance loading.
Landed homes built before the late 1990s were often designed with roofs that carry roughly the weight of the roofing material and nothing more. Adding solar to one of these without structural assessment is how you get sagging trusses, cracked ceilings, and in the worst cases, panel dislodgement.
Pure solar vendors almost never check this. They measure the usable area, propose the panel count, and move on. It's not malicious — it's just that they don't have the structural training or the BCA licence to do anything about it if there's a problem.
We do. When you engage us for solar, the first thing we do is look at your roof's actual structure. If it needs reinforcement before panels go on, we tell you — with a cost for the reinforcement, so you can decide whether solar still makes sense for your property.
We look at your roof's structure — what kind of trusses, whether they were designed with margin for additional load, whether any reinforcement is required before panels go on. This is the non-negotiable first step.
We work out how much solar your roof can realistically host, based on available area, orientation, shading from neighbours or trees, and the structural constraints. We aim for what actually fits, not what maximises our invoice.
We recommend panel and inverter combinations based on your roof size and your energy profile. We'll explain the trade-offs between premium panels and mid-tier panels — most landed clients don't actually need the most expensive option.
If reinforcement is needed, we do it first — using our BCA licence, we can make structural modifications that pure solar vendors can't. Then the mounting system goes in, then the panels, then the electrical work.
We advise on the Energy Market Authority (EMA) approval process, net metering setup, and grid connection requirements. This step is paperwork-heavy and takes weeks — we'll guide you through what's needed and what you actually do yourself vs. what we handle.
After installation, we give you a realistic performance expectation — what kind of generation to expect in different months, how to read your inverter data, when to clean the panels. No overpromises about payback periods.
Solar vendors often quote payback periods based on ideal conditions: south-facing roof, no shading, optimal panel placement, no degradation, unchanged electricity tariffs. Your real-world payback will almost always be longer.
For a typical landed home in Singapore, a realistic payback period is somewhere in the range of 7 to 10 years — depending on your roof, your energy consumption, and how tariffs move. Homes with pools or heavy aircon use see faster paybacks. Homes with modest electricity bills may never reach payback.
We'll give you an honest estimate based on your actual property and actual consumption — not a brochure figure. If solar doesn't financially make sense for your house, we'll tell you that too.
Sometimes the reason to install solar isn't payback. It's energy security, or carbon reduction, or raising the property value. Those are legitimate reasons too. But you deserve to understand which reason applies before committing.

Before you talk to solar vendors, let us come check your roof. We'll tell you honestly whether solar makes sense for your specific property.
