Solar Companies in the Philippines: How to Choose the Right Installer
TL;DR
The Philippine solar market runs from large utility-scale developers down to residential rooftop installers — for a home, you want a residential installer, not a utility developer. There's no single 'best' company; the right one is whoever is PCAB-licensed, experienced with your distribution utility's net-metering process, offers a clear warranty, and can service what they install. This guide covers the types of providers, the vetting checklist, and how to compare quotes fairly.
Search “solar companies in the Philippines” and you’ll get a jumble of utility-scale developers, importers, and rooftop installers all mixed together. For a homeowner, most of that isn’t relevant. Here’s how the market actually breaks down and, more importantly, how to judge any company before you hand over a deposit.
The types of solar providers
- Utility-scale developers build large solar farms that sell power to the grid. They’re the names you see in energy news, but they don’t install on homes. Not who you’re looking for.
- Residential and commercial installers design and install rooftop systems for houses and businesses, handle the permits, and file net metering with your distribution utility. This is the category you want.
- Equipment distributors and importers supply panels, inverters, and batteries to installers, and sometimes sell direct to DIY buyers. Useful if you’re self-installing, but a rooftop system is not a DIY-friendly job.
You’ll come across a range of well-known residential installers as you research — national brands and strong local/provincial outfits alike. Rather than rank them (the right choice genuinely depends on your location, roof, and system), this guide focuses on the checklist that tells you whether any given company is a safe choice.
How to vet a solar company
Judge every installer against the same criteria:
- PCAB license. The Philippine Contractors Accreditation Board licenses contractors. A legitimate installer is PCAB-licensed. Ask for it.
- Track record and references. How long have they operated? Can they show installed projects, ideally near you, and customers you can talk to?
- Written warranty — on both equipment and workmanship. Panels and inverters carry manufacturer warranties, but you also want the installer’s own workmanship warranty covering leaks, wiring, and mounting. Get it in writing.
- Net-metering experience with your utility. An installer who has filed net metering with your specific distribution utility (Meralco, VECO, and others) before will move faster and avoid the back-and-forth corrections that eat weeks. See our net metering guide.
- Proper permits and grounding. They should handle the LGU electrical permit and ground the system to code — a system that skips grounding won’t pass the inspection required for net-metering approval.
- After-sales support. Who services the system if the inverter faults in year three? A brand your installer stocks and supports beats a marginally cheaper one nobody nearby can fix.

Compare quotes, don’t chase names
There’s no single “best” solar company — there’s the best fit for your roof, budget, and location. The reliable way to find it is to get two or three quotes and compare them fairly: equipment brands and warranties, permit and net-metering handling, after-sales support, and price. A suspiciously cheap quote usually cuts a corner you’ll pay for later (see our equipment and safety reviews for what those corners look like).
That’s exactly what we help with: tell us your monthly bill and we’ll match you with vetted local installers who send you quotes directly — no spam, no obligation. Start with the cost calculator, or size a system first with the solar panel calculator.
Frequently asked questions
Who are the biggest solar companies in the Philippines?
The market spans large utility-scale developers building solar farms and residential/commercial rooftop installers who do homes. For a house you want a residential installer, not a utility-scale developer. Rather than chase brand names, judge any company on its PCAB license, track record, warranty, and net-metering experience with your utility.
How do I know if a solar company is legit?
Check for a PCAB (Philippine Contractors Accreditation Board) license, a real business address and track record, references or installed projects you can verify, a written warranty on both equipment and workmanship, and experience filing net metering with your specific distribution utility. Be wary of unusually cheap quotes that skip permits or grounding.
Should I pick the cheapest solar quote?
Not on price alone. The cheapest quote often cuts corners that cost more later — thinner cable, no surge protection, skipped grounding (which fails net-metering inspection), or a weaker warranty. Compare quotes on equipment brands, warranty terms, permit and net-metering handling, and after-sales support, not just the bottom line.
How many quotes should I get?
At least two or three. Comparing quotes side by side is the best way to spot an outlier — a suspiciously low bid cutting corners, or an overpriced one — and to understand the fair price range for your roof and system size.
