The efficiency of solar panels is directly affected by where they are positioned. The photovoltaic modules need enough direct sunlight to generate optimum amounts of electricity, and therefore placement, orientation, and position are of crucial importance.
They are typically installed on roofs or on the ground, but let’s take a look in more detail at the specifics of where they should be sited to ensure premium results.

In general, the orientation of your solar panels will depend on where you live in the world. So, Solar Panels Cheltenham, England, will not have the same orientation as solar panels in Sydney, Australia, for example. Solar panels in Cheltenham, which is in the northern hemisphere, need to face south, while panels in Australia, in the southern hemisphere, will face north. The inclination, or tilt, of the panels will also be considered to allow for maximum energy production.

Availability of Space

The space you have will be a factor in where your panels can be installed. For example, small roofs may offer limited performance, and in that case, ground installation may be a better option. Both can provide benefits to the environment and your energy bills, however, as explained on the Energy Saving Trust website here.

Obstacles and Shade

Shading caused by obstacles will reduce how much energy your solar panels can produce and can also damage them in the longer term. This is why limiting obstacles will be an important factor when the experts decide where your panels should be positioned.

Ground or Roof?

There are advantages to both roof-top and ground-mounted solar applications. Ground installations can offer more choice in terms of orientation and inclination but may not be possible due to shading or space limitations.

Other factors should also be considered, such as cooling and cleaning the panels. You may also want to think about the visual appearance of the panels and how this will affect your property. Ground-mounted options may be better disguised in some cases but may need more mounting materials and foundations, adding to the costs.
