There are three different methods of installing solar panels. Here at Outright solar, we install roof mounted solar panels, ground mounted solar panels and carports. All are good options. Ultimately, we select the option that best meets your specific requirements. If you have plenty of unshaded roof space available then a roof mount is likely going to be the best, cheapest option. If your available roof space is limited and you still want a way to take advantage of the benefits of solar, then a ground mount or carport might be a great option.
We examine the advantages and disadvantages of all the installation methods and what we consider when installing solar for your business, farm or home.

Roof Mounted Solar PV energy system

A roof mount is the most common type of installation for solar panels. This is when the solar racking, which holds the panels in place, is installed directly on the roof of a building. Panels can be attached to flat or sloping roofs. The panels are normally installed facing North-South direction for maximum exposure to sunlight

Advantages
  • Roof mounts utilise space that otherwise wouldn’t be used.

  • Typically the installation cost is lower compared to a ground mounted system or carports.

  • Doesn’t take up land that could be utilised for other activities.

  • Limits unauthorised visitors from accessing the panels.

Disadvantages
  • Requires un-shaded roof space in the north-south orientation.

  • Roof penetration is required for shingle roofs.

  • Could require a new roof before installation.

  • For roof repairs or installation of a new roof, the panels will have to removed reinstalled again.

  • Adds weight to the roof, and in some cases, the roof could require additional support mechanisms.

Ground Mounted Solar PV energy system

It possible that your rooftop isn’t the ideal location for your panels? Perhaps your roof is in a complete shade for most of the day. If you don’t have access to a perfect roof but you do have access to a wide, open space with plenty of sunshine and you want to take advantage of all the benefits of solar energy, then you may be a candidate for ground mounted solar energy system.

Advantages
  • Ground mounts can be installed to face any direction and in almost any location, positioning them for optimal energy production.

  • They can be installed at multiple angles.

  • The system can easily be accessed for maintenance.

  • Easily integrated with solar trackers for maximum energy production.

Disadvantages
  • Typically the installation cost is higher.

  • Limits the use of the land as the land cannot be used or any other functions.

  • Takes up large areas.

  • Easier access for unauthorised visitors.

  • Increased chance for accidental damage from rocks or other particles thrown from a mower and other equipment.

  • Will likely be required to install a fence adding cost to the project.

  • Likely requires mowing around multiple posts and under low clearances.

Carports Solar PV energy system

A solar carport is like a normal carport structure, but with solar panels built in to the roof. This gives it a dual benefit of protecting your car from the sun and the rain, while generating electricity that is used by in the house or if you have an electric vehicle, this could be used to recharge it.

Advantages
  • More Efficient Use Of Space by transforming unproductive parking spots into renewable energy-generation machines.

  • In addition to generating cheaper and cleaner electricity for their owners, solar carports also provide protection of cars from the elements

  • Reduce parking lot maintenance
    as they help channel rain to certain areas.

  • It’s much easier to reorient a parking spot than it is to reposition an entire roof. This allows easy orientation to maximise sun capture generating more energy.

Disadvantages
  • Typically the installation cost is higher than rooftop system.


  • Increased chance for accidental damage cars during parking.
