Can Solar Panels Be Installed on Any Roof, or Are There Limitations?

This is one of the most common questions we get from homeowners and business owners.The short answer is: not all roofs are the same, but most can handle solar with the right system and proper installation.

We’ll explain what works, what doesn’t, and what you need to check before making the switch.

✅ Roofs That Work Well for Solar

1. Metal Roofing (GI Sheet, Rib-Type, or Corrugated)This is one of the best types for solar panels. It’s strong, lightweight, and easy to install mounting brackets on.Most homes in subdivisions and warehouses in the Philippines use this material—so it’s almost always solar-ready.

2. Tile Roofs (Clay or Concrete)You can install solar on tiled roofs, but it takes more care. Mounting brackets need to be handled carefully to avoid breaking tiles.We usually use hooks and supports that fit under the tiles to avoid damage.

3. Flat Concrete RoofsThis is ideal for schools, bungalows, bodega-type buildings, and commercial properties. Since it’s flat, we use tilt mounts to angle the panels toward the sun.This setup gives you flexibility and better airflow under the panels too.

⚠️ What Might Not Be Ideal?

1. Nipa or Lightweight RoofsThese types usually can't support the weight of solar panels and mounting structures. If your roof is made from materials like nipa, we’ll need to check if reinforcement is possible—or suggest an alternative like ground mounting.

2. Old or Damaged RoofsIf your roof is rusty, cracked, or due for replacement in a few years, it’s better to fix it before installing solar. We want your panels to last 25+ years—so the roof underneath has to last too.

3. Small or Heavily Shaded RoofsIf your roof is too small or gets a lot of shade (from trees, walls, or buildings), it might not generate enough power. In these cases, we check for possible adjustments or even design elevated racks if there’s space nearby.

🌤 The Good News: We’re in a Sunny Country

The Philippines receives an average of 4.5 to 5.5 kWh per square meter per day.That means even with partial sunlight or a modest roof size, you can still produce a lot of energy and save on your electric bill.
