5 Components to Consider For Installing Rooftop Solar Panels

People around the globe are shifting towards renewable sources of energy. Renewable power is great in terms of moving towards sustainable development and solar panel installations are becoming a popular form of alternative energy nowadays. Solar panels rank alongside with wind and hydropower as a modern and reasonable energy options for the future of our planet.

Before going into details, just remember solar energy is a clean source and thus using it is a step to clean energy production. The solar power is a cost-efficient and effective way to meet the world’s power requirements. Moreover, it has unlimited supply and no environmental issues.

So, if you are thinking of installing solar panels on your current roof, there are a few things one should consider:

  • Material
  • Pitch
  • Shape and size
  • Orientation
  • Shade

The good news is nearly all types of roofs are compatible with solar panels, the bad that nowadays roofs are not installed with solar in mind. So, you will apparently need to make adjustments.

Let’s take a quick look at each of these factors.


Most roofing materials are compatible with solar panel installation and the roof is not harmed. Asphalt shingles or composite roofing goes great with solar panels and installation process is simple. Metal roof is also compatible with solar panels and installation is easy and cheap.

All above said does not refer to wood and slate roofs.

Pitch or angle 

To get the most from solar panels, you need to point them in the direction that receives most of the most sun energy. The panels need to be tilted to receive the most sunlight on average. This angle is typically the same as your local latitude.

Ideally, a fixed, roof-mounted solar energy system should simply be equal to the latitude of the location where it is installed. Pitch angles between 30 and 45 degrees will work well in most situations.

Shape and size 

Another two features affecting your roof’s compatibility for solar panels – shape and size. Ideally, the best shape and size for panels is a large and square roof.

Orientation of roof

Solar panels are effective when installed on south-facing roofs, though southwest- or southeast-facing panels can still be effective. And you have also an option to ask the contractor dealing with solar panel installation use a rack in order to adjust the orientation.

Amount of shade

Trees, clouds, adjacent solar panels, roofs and buildings are the most common sources of shade. There is a misconception that modern solar panels work even in case of poor light conditions. But it is not that true. Yes, solar panels do work in cloudy days or in shadow places, but their output capacity is compromised. The efficiency losses can be mitigated when the shade tolerant solar cells like Uni-solar are used.
