How to Avoid Solar Scams in the Philippines
TL;DR
The biggest red flags are no PCAB license, no written quote or contract, and an installer offering to skip net-metering paperwork with an unregistered 'guerrilla' connection. Verify PCAB accreditation, insist on a written itemized quote, and confirm the system will actually be registered with your DU before any panel goes up.
The clearest way to avoid a solar scam in the Philippines is to check three things before signing: the installer’s PCAB license, a written, itemized quote, and confirmation that the system will be registered with your distribution utility, not connected as an off-the-books “guerrilla” install. Most solar horror stories in the Philippines trace back to skipping one of those three checks.
What are “guerrilla” solar installations, and why are they a red flag?
“Guerrilla” installs are systems wired directly into a household’s electrical panel without a bi-directional meter and without distribution utility (DU) approval. Meralco and other utilities have flagged a growing number of these — by some estimates, roughly a third of solar systems in Meralco’s franchise area are unregistered. The risks aren’t just regulatory: unregistered backfeeding can keep lines energized when utility workers assume they’re safe, and older analog meters can run backward or trigger double-billing penalties on digital meters that misread exported power as consumption. If an installer suggests skipping registration to save time or paperwork, that’s a hard no. See our net metering guide and permits and requirements guide for what proper registration actually involves.
How do I check if a contractor is actually licensed?
Ask for their PCAB (Philippine Contractors Accreditation Board) license number and verify it against PCAB’s public registry — it should be current, not expired, and cover the right category of work. A contractor without valid PCAB accreditation isn’t legally authorized to execute electrical and structural work like rooftop mounting and grid-tie wiring, which also means any permits they pull can be invalid. Our how to choose a solar installer guide covers the full vetting checklist beyond just the license.
What should a legitimate written quote look like?
It should be itemized, not a single number. At minimum, expect:
| Line item | What to check |
|---|---|
| Panel brand and wattage | Named brand, not “premium panels” with no spec sheet |
| Inverter brand and model | String, hybrid, or microinverter — matches the system type promised |
| Mounting hardware | Rated for typhoon wind loads, not generic brackets |
| Battery (if included) | Brand, kWh capacity, chemistry (LiFePO4 is standard now) |
| Labor and permits | Broken out separately, includes LGU permit and DU application handling |
| Total installed price | Matches the ₱50k-70k per kW grid-tied ballpark, adjusted for your specifics |
If a quote arrives as a text message with just a peso figure and no breakdown, ask for the itemized version before agreeing to anything.
What other technical shortcuts should worry me?
Undersized wiring and non-typhoon-rated mounting are the two most common corners cut to hit a lower price. Undersized cabling overheats under load and is a fire risk; mounting hardware not rated for local wind conditions is a real liability given how often typhoons hit the Philippines. Neither is easy for a homeowner to verify by eye, which is exactly why the paperwork trail — PCAB license, written quote, and proper permits — matters: it’s your leverage if something needs to be redone under warranty. Our warranties guide explains what coverage should look like and what voids it.
What makes a warranty from a shady installer worthless?
The warranty is only as good as the business standing behind it. An unlicensed, informal outfit that quoted you over Facebook Messenger and has no fixed business address is much more likely to be unreachable in year two or three, when a leak, a fault, or underperformance actually shows up. Established, PCAB-licensed installers have more to lose by walking away from a warranty claim, which is one more reason licensing isn’t just a paperwork formality.
Where can I check reviews of installers before I commit?
Check our reviews section for write-ups on panel brands and installers sold in the Philippines, and cross-check any installer’s claims against multiple sources, not just their own marketing. A pattern of vague answers about licensing, no fixed address, or reluctance to put a quote in writing is worth walking away from, regardless of how attractive the price looks.
What if I already have an unregistered system?
Contact your DU to have it formally inspected and registered under net metering rather than leaving it connected off the books. Under the DOE’s faster 2026 process, DUs must approve or reject net-metering applications within 10 working days, so formalizing an existing install is faster than it used to be — and it protects you from penalties and safety risk if the setup is ever discovered during a routine check.
Frequently asked questions
What's the single biggest red flag when hiring a solar installer in the Philippines?
An installer who offers to connect your system without registering it with your distribution utility. These 'guerrilla' installations skip the bi-directional meter and DU approval, which creates real electrical risk and can trigger penalties once discovered.
Do solar installers in the Philippines need a license?
Yes. Legitimate solar contractors doing electrical and structural work should hold a PCAB (Philippine Contractors Accreditation Board) license, which you can verify against PCAB's public registry before signing anything.
What should a legitimate solar quote include?
A written, itemized quote listing panel brand and wattage, inverter brand and model, mounting hardware, battery (if any), labor, permits, and total price — not a single lump-sum number scribbled on a Viber message.
Can a warranty from an unlicensed installer actually be enforced?
Rarely in practice. A workmanship warranty is only as good as the business behind it, and unlicensed, informal operators tend to disappear or become unreachable once a problem shows up months or years later.
Is a very low quote automatically a scam?
Not automatically, but it's the most common sign of corners being cut — usually undersized wiring, cheaper mounting hardware not rated for local wind loads, or panels priced well below tier-1 brands. Ask exactly what's included before assuming it's a deal.
What should I do if I already have a guerrilla (unregistered) installation?
Contact your distribution utility to have it inspected and formally registered under net metering. Leaving it unregistered risks penalties, safety hazards for utility workers, and voided coverage if anything goes wrong.
