How To Install Solar Panels On Roof?

Solar panels help save electricity and make the earth more sustainable. The one-time investment also reduces your monthly spending significantly as it curtains your energy bills down to zero. With time, solar panel technology and its installation procedures have also improved to be hassle-free and convenient for usage. Below are the important steps that you need to follow to install a solar panel on your rooftop.

Solar radiation is light – also known as electromagnetic radiation – that is emitted by the sun. While every location on Earth receives some sunlight over a year, the amount of solar radiation that reaches any one spot on the Earth’s surface varies. Solar technologies capture this radiation and turn it into useful forms of energy.

The amount of sunlight that strikes the earth’s surface in an hour and a half is enough to handle the entire world’s energy consumption for a full year. Solar technologies convert sunlight into electrical energy either through photovoltaic (PV) panels or through mirrors that concentrate solar radiation. This energy can be used to generate electricity or be stored in batteries or thermal storage.

Know the Configuration and Options

The panel should also fulfill the electricity requirements of your home. Other crucial factors to consider include:

  • The ample strength of the rooftop ensures that it can support bulky solar panels.
  • The intensity of sunlight that your rooftop receives.
  • The most appropriate solar panel that you should be installing. 
  • The local compliance guidelines and building codes.

Choose the Appropriate Solar Panel System

Rooftop Solar Mounting Structure is used to fix solar panel with it. You can fix both monocrystalline and polycrystalline panel with it. This is ready to use structure of 1 kw, offered by You can connect 4 panel of 270 watt.

Solar Panels perform at optimum capacity when placed in direct sunlight. When you install your Solar Power system, try to position your photovoltaic panels directly under the noontime sun for maximum efficiency from your photovoltaic unit.

Before Installation, take care of any obstructions to sunlight. Remove all unnecessary obstructions and items such as branches that may block sunlight to your solar unit. You should also trace the path of the sun in the sky and make sure there is no object that may cast a shadow over your solar photovoltaic panels. The operating efficiency of your solar energy unit will suffer because of this shadow.

Size of the System

The next step is to determine the size of the solar system required. You should add up wattage of all the electrical appliances that you plan to use. Calculate how many hours per day the appliances will be used.

If you follow the above steps, you will be able to know the wattage requirement, size of the solar battery needed and the wire size. Remember that correct wire size will prevent overheating of the wires and ensure maximum transfer of power to your batteries.

Determining Important Constraints

For installing a solar panel, you need to consider constraints and factors including pitch, size, orientation, and roof shading, among others. The ideal roof size for installation of a solar panel in a home is 46 m2 or 500 sq. ft. South-facing solar panels may receive the most sunlight and they usually have a slope of 30 degrees.

The pitch of the roof should be between 40 degrees and 15 degrees. However, you can also contact a leading OK Roofing company when you want to install a panel on a flat roof, for the best angle and support. An average-sized home usually has a requirement of 5 Kilowatt of electricity.

The mounting structure provides the base for the entire solar system so make sure it is sturdy and properly fastened to the rooftops of your house or commercial establishment.

The best direction to face solar panels is south, since here they receive the maximum sunlight. East and West directions also work well. North is the only direction that we should not want to put our panels on. Since India lies in Northern Hemisphere, south direction works best here.

Using solar panels is a very practical way to produce electricity for many applications. The obvious would have to be off-grid living. Remote homes and cabins benefit nicely from solar power systems. No longer is it necessary to pay huge fees for the installation of electric utility poles and cabling from the nearest main grid access point. A solar electric system is potentially less expensive and can provide power for upwards of three decades if properly maintained.

This energy creates electrical charges that move in response to an internal electrical field in the cell, causing electricity to flow.

Last, but not least, of the benefits of solar panels and solar power is that, once a system has paid for its initial installation costs, the electricity it produces for the remainder of the system’s lifespan, which could be as much as 15-20 years depending on the quality of the system, is absolutely free!
