Your friendly, hands-on solar partner — helping homes and businesses across the Philippines turn sunlight into real, lasting savings. From your first site visit to long-term support, we make going solar simple and worth it.
Great White Sun installs solar panels and battery systems for factories, businesses, and homes across the Philippines — and we make the whole process clear, honest, and easy to follow.
A dedicated solar and battery installation company — focused on quality systems and long-term care, not one-off sales.
Factories, warehouses, cold-chain sites, commercial estates, and homeowners looking to put idle roof space to work.
Straight answers for owners and finance teams — we design around how you actually use energy, then stay on to support it.
We build the solution around your site — never the other way around. Each service is matched to how your place actually runs.
Turn unused roof space into daytime power and steady savings on your electric bill.
Generate power while giving vehicles and people welcome shade — perfect for parking areas.
Keep your critical equipment running through brownouts and grid dips with smart storage.
See exactly how your system is performing — any time, from anywhere, on your phone.
We stay on as your long-term partner — cleaning, checkups, monitoring, and quick help when you need it.
Design, permits, installation, testing and net metering — all handled for you, start to finish.
Your panels turn sunlight into power, an inverter makes it usable, and your building runs on it first. Add a battery to store extra energy for nights and outages — here's the whole picture.
The right setup depends on what matters most to you — saving money, staying powered, or full independence.
Best for daytime savings
Solar covers what you use during the day; the grid handles the rest. Simple, and the most cost-effective way to cut your bill.
Savings with peace of mind
Solar plus batteries keep your key equipment running when the grid goes down — savings by day, backup when you need it.
Best for remote sites
Panels and storage sized to run entirely on their own, away from the utility — ideal for locations the grid can't reach reliably.
Cut your monthly Meralco (or co-op) bill and protect your family from rising rates. We design a clean, tidy rooftop system sized to your home's usage.
Factories, warehouses, cold storage, malls and offices have big roofs and heavy daytime loads — the perfect match for solar. Most projects pay for themselves in about three years.
Solar systems our team has delivered for retail, manufacturing, automotive, healthcare, institutions and homes — big and small.

Going solar should feel easy. We keep every step clear and coordinated, so you always know what's happening and what's next.
We review your bills, usage and building so every decision is grounded in reality.
We size the system, plan the layout, and pick the setup that fits your needs.
We walk you through the costs and savings before anything is committed.
Careful procurement, installation and testing by an experienced team.
Monitoring, maintenance and quick help — we stay on for the life of the system.
Whether you run a factory or a family home, we make solar make sense — technically, financially, and practically.
High daytime power use where every peso of savings adds up.
Energy-hungry facilities where reliability really matters.
Big roofs and parking areas that are perfect for solar.
Households and communities that want cleaner, cheaper power.
A well-planned solar project gives you value that goes well beyond the energy it makes.
Real savings when your solar covers your daytime power use — money back in your pocket every month.
Keep your most important equipment running through brownouts with optional battery backup.
Easy monitoring so you always know your system is doing its job — no guessing, ever.
It depends on your bill and how much power you use during the day, but many commercial rooftops pay for themselves in around three years — then give 20+ years of near-free daytime power. Send us a recent bill and we'll show you real numbers, free.
Net metering lets a grid-tied system export surplus daytime power to your utility (e.g. Meralco) for peso credits on your bill. For larger sites we usually size to your own use so nearly all the solar offsets your load. We handle the net-metering application for you.
A standard grid-tied system safely switches off during an outage. If you want power to ride through brownouts, we add a battery or hybrid inverter — just tell us and we'll include that option.
We do. Our licensed engineers manage the electrical permit, the utility and net-metering application, and interconnection — plus the structural and single-line design.
From signed contract to switched-on is typically a few weeks, depending on system size, equipment lead time and utility processing. You get a clear schedule with your quote.
Yes. Beyond outright purchase, we can arrange bank financing or a pay-per-kWh arrangement with little to no upfront cost — so your monthly savings help cover the system. Ask us for the options that fit you.
Answer a few quick questions about your home or business and we'll show you the system size, the investment, your payback, and how many years of free electricity come after.
