What would solar actually take off your bill?

Type last month's BILECO bill. You get an honest range, the array size behind it, and the assumptions we used. No email, no phone number, nothing to sign.

02 Scope of work

What we actually install

Every system is designed to one roof, so we do not publish a boxed package. What does not change is the work: these four things are in every job, at the price on your written quote, with nothing added afterwards.

Drawing of a rooftop solar array on a Biliran home An axonometric sheet drawing: a house with a pitched roof carrying twelve rail-mounted solar modules, sunlight marked at 4.5 peak sun hours, with callouts for rails anchored into rafters and clamps torqued to spec, and a drawing title block. 4.5 PSH RAIL ON RAFTER TORQUED TO SPEC MACC SYSTEMS & ENG. ROOF ARRAY BILIRAN, PH
How the parts sit together on a typical pitched roof.
A

The array

Panels sized to your actual consumption rather than to the biggest number your roof could hold.

  • Monocrystalline modules, manufacturer warranty honoured locally
  • Rails anchored into rafters, not screwed to sheet metal
  • Clamps torqued to spec, penetrations flashed and sealed
  • Layout set by roof pitch, orientation and shading, measured on site
B

Conversion and protection

The part nobody sees and everybody depends on when the weather turns.

  • Inverter sized to the array, not to a sales target
  • DC and AC isolation, correctly rated breakers and fusing
  • Surge protection and a proper earth
  • Labelled, documented terminations you can hand to any electrician
C

Storage, only if you need it

Batteries are the expensive part. We will tell you plainly whether your problem needs one.

  • If your problem is the bill, storage may not be worth what it costs
  • If your problem is brownouts, a battery is the only thing that solves it
  • Sized to the circuits you actually want to keep alive
  • Quoted separately and clearly, never bundled to pad a number
D

Paperwork and sign-off

A system that is not properly permitted is a problem you inherit later.

  • Electrical permit prepared and filed
  • BILECO connection paperwork handled
  • Licensed electrician sign-off before energising
  • As-built documentation left with you, not filed away in our office

Solar alone does not keep your lights on during a brownout. A grid-tied system without a battery shuts down when BILECO goes down. That is anti-islanding, a safety rule that stops your roof energising a line someone is working on. If getting through brownouts is the point, you need storage, and we will price it honestly rather than imply the panels alone will do it.

03 The process

How this goes, start to finish

Nothing is due until you have seen the design and the number and said yes to both.

01

Site survey

We come to your house, get on the roof, measure it, look at your service entrance and read your last bills. Free, and you are not committing to anything by booking it.

02

Design and written quote

You get a drawn layout, the equipment list, the expected production, and one all-in number covering equipment, installation, permits and paperwork.

03

Install

Mounting, array, inverter, protection and terminations, done by the people whose names are on this page. Permits filed in parallel so nothing sits waiting.

04

Energised and handed over

Licensed sign-off, then we walk you through what the system does, what the monitoring shows you, and what to do if the inverter ever faults.

The survey and the written quote cost nothing and carry no obligation. The number on that quote is the number you pay — if we missed something, that is our problem, not a change order.

04 Why we started

Power here costs too much and arrives too rarely

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, but with a roof that generates its own power, quoted as one written all-in number with nothing added later.

05 The founders

Who you are actually hiring

We are new, and we would rather you check us out slowly than take our word for anything. Nobody should hand this much money to a logo, so here is who we are and whose problem it is when something goes wrong.

06 Straight answers

The questions everyone asks first

Will solar keep my lights on during a brownout?
Only if it has a battery. A grid-tied system without storage will not — when BILECO goes down, your inverter shuts down with it. That is not a limitation we chose. Anti-islanding is a safety rule that stops your roof pushing power into a line a lineman is working on. If getting through brownouts is the whole point for you, say so and we will size storage and price it honestly. Anyone who tells you a grid-tied system backs up your house is selling you something.
How much does it cost?
We do not publish a price on this page, because a price set before anyone has seen your roof is a guess, and you would be right not to trust it. What you get instead is one written all-in number after the free survey, covering equipment, installation, permits and paperwork. Nothing gets added to it afterwards, and nothing is due until you approve the design.
How do I know you're not a scam?
Fair question, and the right one to ask. MACC Systems & Engineering Inc. is a Philippine stock corporation registered with the Securities and Exchange Commission on 11 August 2026, Reg. No. 2026080263439-51. Look it up on the SEC's own site rather than taking our word for it. The founders are named on this page with their PRC numbers, every job gets licensed electrician sign-off, and nothing is due until you approve the design. We are early, and we have no customer photos to show you yet. We would rather say that than borrow someone else's.
What happens in a typhoon?
Mounting is the part that matters. Rails land on rafters rather than sheet metal, clamps are torqued to spec, and every roof penetration is flashed and sealed. We would rather quote a smaller array anchored properly than a bigger one that becomes a sail.
Do you handle the permits?
Yes. The electrical permit and the paperwork for your connection are part of the job, not an extra line. You should not have to project-manage your own build. Ask us about exporting surplus back to BILECO and we will tell you exactly where that stands rather than guess at it.
Can I pay monthly?
Tick the installment box on the form and we will lay out what is realistically available to you. We would rather tell you honestly what the options cost than pretend financing is free.
How long have you been doing this?
MACC was registered in August 2026, so as a company we are new, and you should weigh that. What is not new is the people: a Registered Electrical Engineer with twelve years of project and site supervision, and three others running a registered software firm and its support desk. We are building a track record on this island one roof at a time, and we would rather be honest about where we are in that than invent a history.
