Red Flags in a Solar Quote: An Annotated Example
Most bad solar quotes are not obvious scams. They are small, easy-to-miss omissions that compound. Here is one realistic, illustrative Singapore solar quote, annotated line by line, and what a genuinely good version of the same quote says instead.
Quick answer
A realistic Singapore solar quote can carry ten or more red flags without a single obvious scam element. A suspiciously low price per kWp, a vague equipment description, an unstated savings basis, an undifferentiated warranty claim, a large deposit before any site survey, and a 24-hour validity window are the common ones, and most compound rather than standing alone. The example below is one illustrative quote, annotated line by line.

Distinct red flags found in one realistic, illustrative Singapore solar quote, from a suspiciously low price per kWp to what it leaves out entirely
Most bad solar quotes are not obvious scams. They read like ordinary marketing, use real technical terms, and often come from a company that is genuinely operating, just cutting corners somewhere the quote itself doesn't disclose.
The example below is one realistic, illustrative quote, not a real company, annotated line by line for what each item actually signals and what a genuinely good version would say instead.
What does this quote actually say?
| Line | What the quote says |
|---|---|
| Installer | [Installer Name] Pte Ltd |
| System size | 12kWp, premium panels |
| Total price | S$10,800, all inclusive |
| Estimated savings | Save up to S$3,500 a year! |
| Warranty | 25 year warranty included |
| Payment terms | 50% deposit to confirm booking, balance on completion |
| Validity | This price is valid for 24 hours only |
Why is S$10,800 for a 12kWp system worth questioning?
That works out to S$900 per kWp, below the typical S$1,000 to S$1,600 range for a Singapore landed home installation. See solar panel cost by system size for the full pricing breakdown this range is drawn from.
A price this far under the range is not automatically dishonest, but it usually means something specific is being cut. Proper scaffolding, balance of system quality, or licensed labour are the most common places that happens, and a confident installer can name exactly what lets them price this low.
Why does 'premium panels' by itself tell you nothing?
No brand, no model, and no wattage means there is nothing here to actually verify. A specific panel model lets you check EMA's approved equipment list and the manufacturer's own datasheet directly. The word "premium" with nothing else attached verifies nothing at all.
Why is 'save up to S$3,500 a year' a red flag on its own?
The phrase "up to" describes a ceiling, not a typical outcome, and this figure states no basis at all. There's no mention of whether it's a P50 or P90 generation estimate, and no reference to your household's actual electricity consumption.
See how to evaluate a savings guarantee for what a genuine, defensible savings figure actually specifies in writing.
What's actually wrong with '25 year warranty included'?
A real Singapore solar installation carries at least three separate warranties, product, performance, and workmanship, each from a different party and running a different length. Product warranties commonly run 10 to 12 years, performance warranties run 25 years but guarantee a declining output percentage rather than a flat promise, and workmanship warranties commonly run 12 months to 5 years, not 25.
A single undifferentiated "25 year warranty" line either means the quote is only describing the performance warranty and leaving the other two unstated, or is genuinely overstating workmanship coverage. See solar panel warranty types explained for what each one should actually specify.
Why does a 50% deposit before any survey matter?
A reasonable deposit structure keeps the initial payment in the 10 to 30% range, released against actual progress rather than upfront in full. Half the contract value requested before a site survey has even happened is well outside that norm.
If the company stops trading partway through, a large upfront deposit is money genuinely at risk. See what happens if your installer goes out of business for what a safer payment structure looks like and why it matters most in the period before commissioning.
Why does a 24-hour validity window matter?
There is no genuine reason a S$10,800 decision needs to be made within a day. A real installer understands that this is worth comparing against at least one other quote, and a validity window this short is a pressure tactic more often than a genuine limited-time price.
What does this quote leave out entirely?
Five things that don't appear anywhere on it, and their absence matters as much as anything it does say.
- No BCA ME03 license number, so the company's authorisation to do this specific work cannot be verified at all.
- No UEN or ACRA registration mentioned, so even the company's basic legal existence hasn't been made checkable.
- No mention of GST treatment, so it's unclear whether S$10,800 is the actual final price.
- No Defects Liability Period stated separately from the vague warranty line.
- No mention of who handles the SP Group grid connection application, a step that should be the installer's job, not yours.
The BCA and ACRA checks answer different questions. BCA confirms the company is licensed to do solar work specifically; ACRA's free Bizfile search confirms the company legally exists at all, under the name it gave you. A quote naming neither leaves both open.
What would a genuinely good version of this quote say instead?
The same 12kWp system, priced honestly: S$14,400 (S$1,200 per kWp, itemised with scaffolding as its own line), a named Tier 1 panel model with a datasheet reference, a savings estimate stated as a P90 figure calculated from your actual consumption data, product and performance and workmanship warranties listed separately with their real lengths, a Defects Liability Period stated explicitly, a 20% deposit with the balance released against progress, and no expiry pressure.
Every one of those changes is checkable against the 25-point solar buyer checklist, which is the fuller version of the same exercise applied to a real quote in hand.
How many flags together mean you should just walk away?
One or two vague items, especially the equipment description or an unstated savings basis, are worth a direct question first. Three or more together, particularly when urgency pressure is paired with a missing BCA ME03 number or an unstated Defects Liability Period, are a stronger reason to treat this specific quote as disqualified and move to a second one instead of negotiating.
What's the actual next step?
Run the Sunnify solar estimate first, so you already know what a fair system size and price look like before any quote lands in your inbox.

FAQ
Frequently asked questions
No. A single flag is often an incomplete early quote rather than an intentional omission, and it is worth a direct follow-up question rather than an automatic disqualification. Several flags together, especially urgency pressure combined with missing credentials, is the stronger signal.
Not always. Some installers genuinely operate with lower overhead or a smaller margin, and that alone can explain a lower number with nothing cut anywhere. What matters is whether the installer can explain the specific gap when you ask directly, rather than offering a vague reassurance instead of an answer.
A missing or unverifiable BCA ME03 license number, since every other item on the quote, the warranty, the equipment claims, the price itself, only means anything if the company behind it is who it claims to be. Confirm this first, before scrutinising anything else.
It depends on the count and type. One or two flags, especially vague rather than false statements, are worth raising directly and seeing how the installer responds. Several together, particularly urgency pressure paired with missing credentials, are a stronger reason to get a second quote instead.
