Top 7 Steps To Install Solar Panels On A Roof: A Beginner’s Guide

“I have no doubt that we will be successful in harnessing the sun’s energy. If sunbeams were weapons of war, we would have had solar energy centuries ago.

↝↝ George Porter”

There has never been a shade of doubt that solar energy is the way forward. Whether it’s rooftop solar panels, commercial ground-mounted solar power plants, or floating solar plants, the entire idea behind using them is to generate clear and green electricity that’ll save the Earth and reduce the cost of electricity.

We all fancy the idea of installing solar panels on roof at some point in time: what holds most of us back is incomplete or no information. That is why we’ve curated this informative beginner’s guide to walk you through the aisles of installing solar panels on roof.

But first things first – trying the DIY way of installation has many risks. You might fall and even fail to pick the ideal spot for solar system installation.

Solar installation is a hefty one-time investment, and you would want to get it right the first time itself. That’s why we’re here to help.

Take a plunge and explore the correct installation method so that your solar system lasts for decades.

Top 7 steps to install residential rooftop solar systems

#Step 1

Do rigorous research to hire the best solar installation company

Everything, in the end, will boil down to your choice of installers. Don’t rely on random companies.

The best way to judge the trustworthiness is to find out whether or not the company is UL-certified: there can never be a certification bigger than that!

The pre-installation inspection and post-installation maintenance services matter too. Very limited EPC solar companies offer financial assistance in the form of easy loan approvals and zero-interest EMI services.

Looking for such solar companies is the first necessity if you want your rooftop solar panels installed the right way.

#Step 2

Take Rooftop Inspection Seriously

Solar installation companies send solar consultants for rooftop inspection for a bundle of reasons:

  • Checking the condition of the roof to ensure it is spacious enough and strong enough to take the load of mounting structures.
  • Ensuring that the space isn’t shaded by trees or surrounding buildings.
  • Ensuring there’s an uninterrupted supply of solar energy during the day (9 AM to 4 PM), especially during peak hours (11 AM to 2 PM).

#Step 3

Don’t undermine the advise of solar consultants

Solar consultants are rooftop Gurus. When they make an inspection, they’re using all their skills to ensure that solar panels on roof would work as promised after installation.

They have the right skills to locate the best tilt angle for mounting rooftop solar panels.

Ideally, the South direction gets the most sunlight in India. If you’re based in the South, the tilt angle of rooftop solar panels would be ten degrees.

The angle increases as you head towards the North. If you’re based in North India, the tilt angle of the rooftop solar panels has to be more than 20 degrees.

There’s so much hype about the tilt angle of the solar panels on roof because the more sunlight falls on them, the more power they generate. The more the power, the higher the monetary returns.

Undermining the suggestions regarding the tilt angle or condition of the rooftop will, later on, reduce the efficiency of the solar system.

#Step 4

Know your roof before you know the rooftop solar panels

As they say, better safe than sorry!

The roof has to be in perfect condition before you can mount a solar system on top. Besides, there are different types of roofs, and different types need different mounting structures.

For instance, if your rooftop is an RCC, it can hold more weight. Such roofs are ideal for hot-dipped galvanized steel mounting structures.

On the other hand, if the roof is made of metallic sheet, lighter, aluminium rail structures are the right options.

So, know your roof the best you can before deciding which type and size of the rooftop solar system you want to install at your home.

#Step 5

Learn about your power requirement

Solar rooftop systems don’t cost a penny – says who?

A rooftop solar system requires an upfront investment. Although that cost breaks even within a couple of years, you still have to invest in them first.

There’s no smartness in installing a 5 KW rooftop solar system if a 3 KW system can cover your power requirement. Keep in mind the average electricity units you consume every month.

When a solar consultant visits your house, ask as many questions. The more closely you know your consumption, the smarter the investment will be.

Naturally, a 5 KW solar system will be more expensive than a 3 KW solar system, and so on.

Always look at your requirements before installing solar panels on roof so that the cost breaks even soon.

#Step 6

Know your solar system at the back of your hands

We hate to break it to you, but a rooftop solar system isn’t your average gadget. It’s an advanced technology that’s complex.

There are many components in a solar system, and all those components have to be arranged in a specific manner.

It’s always a great idea to know those components. Let’s break them down for you:

  • solar panels
  • Mounting structures
  • Solar inverter
  • DC combiner box
  • AC combiner box
  • DC cables
  • AC cables
  • Earthing wires
  • Earthing strips
  • Earthing rods
  • Earthing kit
  • Lightning arrester
  • MC4 connectors

Each component has to be connected very closely so that your rooftop solar panels can gather maximum sunlight and generate electricity.

#Step 7

Watch the experts mount the solar system

You know the components, they know how to assemble those components. Once you’ve chosen the solar system you want, let experts mount the structure safely.

Don’t try to mount solar panels on roof on your own. There’s a safety risk, you can fall. There’s an efficiency risk, you might not be able to assemble the components in the right manner.

There’s a financial risk too, solar cells in solar panels are delicate. If manhandled, their efficiency will be affected.

No matter the angle you choose to look at, installing rooftop solar panels on your own will never be the right method. It will only cost you money rather than saving a few bucks.

Conclusion:

Rooftop solar panels are game-changers. A solar system produces clean electricity. Not only does it lessen the electricity bills (you can save a minimum of Rs. 40,000), but it also helps save the planet.
