About AGESI

An engineering firm, 
not a panel reseller

Allied Green Energy Solutions Inc. designs, engineers, and installs solar power systems across the Philippines. We do our own design, our own load studies, and our own installation — which is why our proposals contain a bill of quantities rather than a lump sum.

Why we started

AGESI began because we wanted solar for ourselves. We were watching electricity prices climb year after year across our own homes and our own businesses, and it was obvious the trend wasn't going to reverse. So we went looking for someone to install it.

What we found was a market split in two. At one end, properly engineered systems priced well beyond what the numbers justified. At the other, installers quoting almost nothing and delivering systems that showed it. In between, very little. What struck us most was how few of them could answer straightforward questions — how the array would be secured, what happened to the roof underneath it, what the actual return would be once you accounted for how much power we'd use during the day rather than export. And none of them seemed willing to put their name behind the answer.

So we built the company we'd been looking for. The first systems we installed were on our own properties, where we had every reason to get the engineering right and no one to blame if we didn't. Then friends asked. Then their businesses asked. Then people we'd never met started calling. Forty-three projects later, we still design every system the way we designed those first ones — for a client who is going to live with it for twenty-five years and ask hard questions along the way.

Before you commit


Sizing from real data

Every proposal is built from your actual billing history.

We answer the hard questions

How the array is secured, what happens to the roof underneath it, and what the return actually is.

We tell you when not to buy

If your roof needs replacing first, or the numbers don't work, we say so.

Once you do


Our own people do the installation

Our engineering team, not subcontracted labor.

We help with the permits

The utility application and LGU paperwork are our problem, not yours.

We're still here in year ten

Monitoring, warranty claims, and maintenance long after the invoice is settled.
