How to Choose a Solar Installer in the Philippines

Choose a solar installer in the Philippines by checking four things before you sign anything: they’re a registered business with a real track record, they handle your net-metering application, they give you a clear written quote using quality equipment with proper warranties, and they stick around for after-sales support. Installers who fall short on any of these are worth walking away from, no matter how good the price sounds.

The vetting checklist

Run through this before committing to an installer:

• Business registration. DTI (sole proprietorship) or SEC (corporation) registration, plus a valid business permit. Ask to see them.
• Real portfolio or references. Photos of actual completed installations, and ideally a past customer you can contact or a location you can see in person.
• Net-metering handling. The installer prepares and submits your net-metering application to your utility, not you. See our net metering guide for what that process involves.
• Clear written quote. A quote that spells out system size, equipment brands and models, scope of work, and total price in writing, not a verbal estimate or a one-line text message.
• Quality panels and inverters with warranties. Recognizable brands backed by a panel product warranty, a panel performance warranty, and a separate workmanship/installation warranty covering the installer’s own labor. Check our brand reviews and best solar panel brand guide if you’re unsure what to look for in the equipment itself.
• After-sales support. A clear answer on who to call if a panel, inverter, or the system’s output has a problem after installation, and what that support covers.

Red flags to walk away from

• No business registration or permit, or reluctance to show one.
• No references, no portfolio, no way to verify past work.
• Vague or verbal-only quotes with no itemized breakdown.
• Pressure tactics — rushing you to sign, “today only” pricing, or refusal to let you think it over.
• No workmanship or installation warranty, even if the panels themselves carry one.
• Prices far below normal market ranges (roughly ₱150,000-250,000 for a 3kW system, ₱250,000-400,000 for a 5kW system) with no clear reason why.

Questions to ask an installer

• Can I see your DTI/SEC registration and business permit?
• Can you show me past installations, or connect me with a past customer?
• Will you handle the net-metering application with my utility?
• What’s included in the written quote, and what could add to the price later?
• What warranties come with the panels, inverter, and your workmanship?
• What happens if something goes wrong after installation — who do I call, and what’s covered?

The easier way to shortlist installers

Vetting every installer yourself takes time, and it’s easy to miss a red flag when you’re comparing quotes on your own. Use our cost calculator to get matched with vetted local installers who send free quotes, so you’re starting from a shortlist that’s already passed the basics above.
