How to choose a solar installer in Singapore.

The right installer is licensed, transparent on the quote, and stands behind its warranties. Here are the green flags to look for, the red flags to walk away from, and the questions that protect you.

Start with an honest survey See your numbers first

Read the signs

Green flags, red flags.

You can tell a lot before you sign anything. Here is what good looks like, and what should make you pause.

Green flags

Proper scaffolding budgeted in, never cut to win the job
The team that quotes is the team that installs
BCA-licensed, and happy to show it
A clear, itemised quote with nothing vague
Tier-1 panels with real product and performance warranties
A written workmanship warranty and references you can call

Red flags

A suspiciously cheap quote that has shaved the scaffolding
Cannot say who actually installs, or quietly outsources it
Pressure to sign today, or a deal that expires tonight
A vague lump-sum quote missing permits or connection
Unbranded, no-name panels and inverters
A large upfront deposit, or cash only

Before you sign

Six questions worth asking.

A good installer answers all of these without flinching. Hesitation on any of them tells you something.

Do you use proper scaffolding, and to what extent?

Are you the ones installing, or is any of it outsourced?

Exactly which panels and inverter, and what are the warranties?

Is the quote all-in, including permits, connection, and electrical work?

What does your workmanship warranty cover, and for how long?

Can I speak to two recent customers near me?

Or skip the vetting

Common questions

Choosing well.

What should I look for in a Singapore solar installer?

A team that installs its own work, budgets proper scaffolding for safety, gives a clear itemised quote, uses tier-1 equipment with real warranties, and has references you can call. BCA-licensed is the baseline.

Why does scaffolding matter when choosing an installer?

Singapore enforces strict site-safety rules, and proper scaffolding, often S$2,000 to S$6,000, is what keeps the crew safe on your roof. It is the first thing a too-cheap quote quietly cuts. Experienced workers are not safe workers without it.

Should I just take the cheapest quote?

Rarely. A quote far below the others has usually compromised somewhere you cannot see, often on scaffolding and site safety, or by outsourcing the install. Compare the equipment, the warranty, and who actually does the work.

Is a longer warranty worth paying for?

Usually, yes. Panels and inverters run for decades, so strong product, performance, and workmanship warranties protect a five-figure investment. A thin warranty is a quiet red flag.

Can Sunnify recommend an installer?

Yes. We give you the honest numbers first, with nothing to sell you. When you are ready, we hand over to our BCA-licensed installer partners, who handle the survey, design, and installation to Singapore safety standards.
