7 Reasons Why Solar InRoof is a Better Solution than Solar Panels on Roof!

For a lot of us, a solar plant means a row of panels sitting on the terrace roof, at an angle. The old solar roof setup is ugly but functional. That is the traditional way of harnessing power.

But solar technologies have evolved.

Not all solar plants need to look the same way anymore. They can be adapted according to unique preferences and power requirements. Think solar panel windows, façades, or solar roof tiles.

One technology that extracts the maximum output from a rooftop without compromising on efficiency or design is Solar InRoof — a roof made of solar panels. It’s also one of the most practical ways to replace old solar roof sheeting that has started to rust, leak, or simply lost its structural strength.

Let’s understand how InRoof — India’s first integrated solar roof works, its advantages over traditional systems, and whether InRoof is right for you.

Imagine looking up in a big factory, but instead of a dull metal roof, you see the luminescent backsheets of solar panels.

With solar InRoof, you don’t need metal sheets. Instead, solar panels become your primary roof structure. There are multiple ways to install InRoof. For a new building, the solar roof is integrated into the foundation itself. It’s also possible to replace an old solar roof or metal sheet setup with an InRoof structure for a more efficient, leakproof, and aesthetic solution without hiring a separate roofing contractor to redo the base structure first.

Or you can set up a pergola-type InRoof on top of your terrace or unused ground space. This way, you get a completely functional shaded spot that also powers your building.

InRoof works well for both small-scale applications (pergolas, carports, corridors, cafes, gyms) and large-scale applications (factory roofs, playgrounds, rooftop restaurants). It can also be customized to different needs, applications, and roof styles, including sites that currently use metal roofing.

Solar panels installed over metal sheets tend to heat up, and heat brings down efficiency. InRoof eliminates metal sheets and allows free air circulation underneath the panels. As a result, InRoof is 10-15% more efficient than traditional rooftop solar installations, and this advantage holds over the long term as panels age.

Traditional solar panel mounting structures are installed by drilling into the existing roof structure. While most installers ensure adequate waterproofing during solar panel installation, structural damage over time can still create the possibility of leakage—one of the most common reasons homeowners eventually need roof repairs.

InRoof, on the other hand, has to work as the primary roof for large and small buildings, so there cannot be even the slightest possibility of leakage. That is why the solution includes a double layer of leak protection that can withstand the heaviest rainfall, without needing a separate roofing contractor for waterproofing.

With solar panels sitting on top of an existing roof, the space has a single function — generating electricity. The space underneath stays unusable.

That’s not the case with InRoof, which creates a self-powering, comfortable spot underneath that can serve multiple purposes. From a mini gym to a clean energy-generating carport, the applications are practically endless.

You can even build a whole new floor using InRoof, without needing extra permissions for it.

A traditional solar system needs roughly 90-110 sq. ft. of shadow-free roof or ground space to install 1 kW of solar capacity, since panels are mounted with gaps in between. With InRoof, the same 1 kW of capacity fits into just 60-65 sq. ft.

The benefit: InRoof accommodates 26% more panels in the same footprint and generates more power than a conventional solar system of the same size.

One of the biggest appeals of this futuristic solution is aesthetics. Protruding solar panels aren’t visually appealing and often detract from a building’s design.

InRoof’s assembly, however, is seamless. All you see is a vibrant, futuristic roof with no protruding parts. Whether it’s a pergola or a terrace shed, InRoof doesn’t just avoid looking out of place — it actively elevates the aesthetic appeal of a space, and it can be adapted to all kinds of roof styles and architectures, including buildings that previously relied on plain metal roofing.

If your existing metal or sheet roofing is old or rusted, installing solar panels directly on top can compromise its structural integrity. In most such cases, a roofing contractor will recommend a full roof replacement before you go solar, which adds significantly to your total cost.

Since there’s little to no need for a separate metal structure with InRoof, you end up saving money in the long term. InRoof is also compatible with all types of solar panels and inverters, which makes it more cost-effective overall than a traditional rooftop solar or BIPV installation that requires you to replace old solar roof sheeting separately.

Getting rid of sheet or asbestos roofing is a big plus for the environment — it helps cut down on harmful carbon emissions. To put this in perspective, manufacturing one ton of corrugated sheet releases about 1.85 tons of CO2 into the atmosphere.

This means choosing InRoof over a regular rooftop solar setup is more eco-friendly and a meaningful way to reduce your building’s long-term carbon footprint.

If you’re already searching for ways to replace old solar roof sheets or rusted metal panels, it usually comes down to one of a few situations: recurring roof repairs, visible leaks after monsoon season, declining structural strength, or simply wanting to add solar capacity without paying twice for a roofing contractor and once for a solar installer. InRoof is designed to solve all of these in a single project, since the solar structure is the new roof rather than an addition sitting on top of an old one.

InRoof is for everyone who has access to a sunlit spot, no matter how small or big, and wants to cut down on electricity bills. It works for residential, commercial, and industrial spaces. To simplify the decision, ask yourself these questions:

1. Are both energy efficiency and aesthetics a priority for your new building?

If you’re setting up a new building — perhaps a factory or warehouse — and want to power it with solar energy, InRoof is worth considering. This solution won’t compromise the building’s aesthetics.

The leading FMCG brand B.L Agro chose the InRoof solution for its new production facility in Bareilly, UP.

Plant size: 745kW

Roof Area: 45,000 sq. ft.

2. Is there a space at your home/office that you wish to use?

If you want to make an idle sunlit spot usable- InRoof would be a great investment. Perhaps you want to develop a cozy hangout space on your terrace or set up a carport in your office parking area. With InRoof you have the option to use underutilized spaces and turn them into energy-generating and modern spaces.

A private residence in Alibaug, Maharashtra used InRoof to set up a scenic poolside pergola.

• Plant Size: 11.77kW
• Roof Area: 765.05 sq. ft.

3. Is your metal roof leaking and are you looking for a better solution?

Roof leaks are common with metal roofing. If you want to upgrade your metal roof or replace it to install solar panels on top, directly switching to InRoof would be a great option.

India’s biggest uPVC pipe manufacturer, Ashirvad Pipes, replaced the metal roof of their Bengaluru factory with the InRoof solution

• Plant Size: 91kW
• Roof Area: 6630 sq. ft. sq. ft.
