Solar power, sized right, for your home or business.
PTG Solar installs Tier 1 and Tier 2 solar inverters, wired with proper combiner box protection — sized by real load calculation, not guesswork. The sun does the work; we make it usable, safely, in your home.
Engineering-backed, built for the long run.
PTG Solar is a Quezon City-based solar installation company built on a solid engineering background. Before we recommend a system size, product tier, or protection setup, we calculate your actual electrical load — so you get a system matched to what you actually need, sized and priced right the first time.
We handle the full scope ourselves: professional installation, combiner box wiring, and breaker sizing — then stay on call for troubleshooting consultation and aftersales support once your system is up and running.
Everything needed to go solar, safely.
One team handles planning, installation, and protection — so nothing gets lost between contractors.

Know your load before you size your system.
Before you reach out.
Do I need a load calculation if I already know my bill?
Your bill tells us your total usage, but not which appliances draw the most power at once. Load calculation makes sure your system and breakers are sized for real conditions, not just an average.
Why these inverter and battery brands specifically?
We've installed and supported Solis, Growatt, SRNE, and Top One Inverter, plus LVTOPSUN, Fidus Pylontech, and CST batteries — and are confident in their reliability and after-sales parts availability in the Philippines.
What's inside the combiner box?
TOMZN and EARU breakers, a surge protection device (SPD), an automatic transfer switch (ATS), battery and PV cables from Huizhou Transocean Electronics Co., and an MCCB — packaged so your system is protected from day one.
