Lower your BILECO bill. Typhoon-ready installs by an on-island engineering team, at one fixed price.
Put in last month's BILECO bill. You get an estimated monthly saving, a payback range, and which package fits — before you talk to anyone.
Estimates use conservative assumptions for Biliran sun hours and a standard residential system. Your real numbers come from the free site survey — roof pitch, shading and your actual usage all move them.
estimated saving on your bill
One fixed package price, quoted to your roof and your bill — panels, inverter, mounting, wiring, permits and paperwork included. What changes between packages is what it does for you.

All three put panels on your roof. What differs is where the power goes when the sun sets and when BILECO goes down — which is the whole basis for choosing between them. Here is the wiring, in plain terms.
The simplest and cheapest way to cut your bill. No battery.

Your panels feed a grid-tie inverter that powers whatever your house is using at that moment. Daytime consumption comes off your roof instead of off your bill. At night there is nothing stored, so you draw from BILECO exactly as you do now.
Fewest components, fewest things to fail, lowest upfront cost of the three — the battery is most of the price difference.
Fits you if: your power is reasonably steady, your bill is the thing that hurts, and you would rather put every peso into cutting it than into batteries.
Cuts the bill and rides through brownouts. One inverter does both.

A hybrid inverter runs your house off the roof during the day and puts the surplus into a battery instead of wasting it. In the evening the house draws the battery down. BILECO stays connected underneath as a fallback for the nights the battery runs out.
You choose which circuits sit on the backed-up side — typically lights, fans, the router and the fridge. Heavy loads like aircon usually stay on the grid side, because backing them up multiplies the battery you need.
Fits you if: BILECO drops often enough to be a real problem, you want the bill down as well, and losing the fridge or the workday costs you money.
No utility connection at all. Your roof and your battery are the whole supply.

Panels, a battery bank and an inverter, with no wire to BILECO. The battery has to carry the whole house overnight and through cloudy stretches, so it is sized for every load you own rather than a chosen few — which is why the battery, not the panels, drives the cost.
Built for places where the grid is unreliable, absurdly expensive to reach, or simply not there. If a pole run to your lot would cost more than a system, this is the cheaper answer.
Fits you if: there is no service at the lot, connecting would cost more than the system, or independence from BILECO is the point rather than a side effect.
Not sure which one your roof and your bill point to? Send the form — the free site survey and written estimate exist to answer exactly that, and nothing is due until you approve the design.
Who we are: Biliran-based engineers doing fixed-price residential installs — no showroom, no commissioned salesmen, no surprise add-ons on the final invoice.
Why now: BILECO rates keep climbing, brownouts keep coming, and the nearest full-service installer is a ferry ride away. We live here — warranty calls are a drive, not a shipment.
The survey and the written quote are free. Nothing is due until you approve the design — and the number on that quote is the number you pay.
Every household on this island has quietly built its life around two facts: the electric bill takes a bigger bite than it should, and the power goes out when you least want it to. Dinner gets replanned. The kids study by phone light. The bill arrives anyway.
We are four engineers who think that is a solvable problem rather than a permanent condition. Not with a cheaper bill you have to argue for — with a roof that generates its own power, quoted as one fixed all-in number with nothing added later.
Nobody should hand this much money to a logo. Here is who we are, and whose problem it is when something goes wrong.
“Your roof and your wiring are mine. I design it, I supervise it, I sign it off.”
“I already run one registered Philippine company with real clients. I run the paperwork side of this one — so there is still someone here when your warranty matters.”
“I have seen which contractors send a clear price and show up, and which go quiet after the deposit. Your price and your paperwork are mine.”
“When something breaks, someone has to actually pick up. That is my job here.”
Your package price depends on your roof and how much of your bill you want covered. Send the form and we send back a written, all-in number.
